| − | For rural development, energy was, and in some cases still is, looked at as having two distinct uses: residential and productive. Residential uses of energy are expected to positively impact the rural quality of life or improve rural living standards (1, 2). The productive use of energy in rural areas is expected to result in increased rural productivity, greater economic growth, and a rise in rural employment, which would not only raise incomes but also reduce the migration of the rural poor to urban areas. With respect to agricultural production, electricity would be used principally to provide motive power for agriculture-based industries and would power farm machinery, such as water pumps, fodder choppers, threshers, grinders, and dryers. Thiswould result in the modernization of agricultural production. Electricitywould bring an increase in irrigation, which in turn would result in an increase in the amount of required labor. The generous output of these modernized farms would provide inputs to large commercial enterprises such as rural cooperative sugar factories. Another example includes the use of electricity as a source of driveshaft power and lighting, which is suitable for rural industries, for example, machine shops. In the past, a common belief was that once a rural region was provided with electrical service and access to modern energy, rural industries would expand and the quality of rural products would improve. Over the long run, the availability of modern energy services would provide significant indirect social benefits such as greater equity and improved quality of life. In short, if energy was used for productive applications, itwould transform an underdeveloped agrarian economy. Not surprisingly, the process has proved to be more complicated (3–5). One example of this is India. India has a long history of supporting rural electrification for productive uses, in recognition of the potential benefits for the country in terms of poverty alleviation and food self-sufficiency. A major component of India’s rural electrification program since the late 1960s has been to promote electricity for irrigation pumping by heavily subsidizing agricultural electricity rates (6, p. 13). Since then, 13 million pump sets have been put in use for irrigation by Indian farmers. Partly owing to the high prices of other pumping alternatives such as diesel, and partly owing to the constrained capacity of the State Electricity Boards, today there are substantial waiting lists for irrigation pump-set connections in most Indian states. Thus, this program in India has been relatively successful in promoting productive uses—particularly in the form of irrigation. However, electricity use by households has not kept pace with its use for irrigation pumping, and it is estimated that only about 44% of rural households actually have electricity in their homes. Bangladesh, by contrast, has witnessed a more balanced approach toward rural electrification. The rural electrification program in Bangladesh stressed both residential as well as productive uses of energy and has met with reasonable success (7, 8). Lack of adequate electricity for households has important gender implications as well. Because agriculture and cultivation are usually male domains (with homes being female domains), the traditional definition of productive use of energy has an inherent gender bias (9). This bias is evident in the rural marketplace as well. Even in rural areas where households have access to electricity, markets stock leisure items such as televisions and radios but not labor-reducing modern cooking appliances for women. Because men serve as the decision makers in households, the market tends to cater to their needs over women’s (10). In Indonesia, a survey of a relatively wealthy rice-growing region found that the rate of growth of pump sets was low and that most irrigation continues to be successfully accomplished through traditional, gravity-fed methods. Furthermore, the price of kerosene and diesel in Indonesia was heavily subsidized, making it less attractive for those farmers who used diesel pumps to switch to electricity. Thus, experience suggests that there are many different ways to promote productive uses of energy. This has important consequences not only in shaping the program but also in producing the types of benefits needed for rural areas.

| − | == EMERGING VIEWOF PRODUCTIVE USES OF ENERGY ==
| + | [[Category:Rural_Electrification]] |
| − | | |
| − | The view that the productive use of energy for rural development is primarily one of motive power is now changing. There are several reasons for this change. First, some recent studies have documented that lighting for rural nonfarm businesses actually improves productivity and provides additional income for rural people (11). Secondly, there is growing evidence that electricity use in rural homes is related to an improvement in education levels (12). And, because there is a welldocumented relationship between lifetime earnings and education, a use of energy that positively impacts education can be considered productive (13). For instance, one study that stresses the value of human capital in development states, “The main engine of growth is the accumulation of human capital—or knowledge—and the main source of differences in living standards among nations is a difference in human capital. Physical capital plays an essential but decidedly subsidiary role” (14).Finally, access to modern energy services can lead to improvements in health. Although there are very few studies examining the relationship between electricity and health, there is a growing body of literature on indoor air pollution and its impact on both morbidity and mortality (15, 16). And because people who are unhealthy cannot work as much as people who are healthy, surely improved health will lead to higher incomes. Thus, the uses of energy in homes or businesses, which can have a positive impact on social development in many contexts, are also productive. In June 2002, the Global Environment Facility (GEF) and the Food and Agricultural Organization (FAO) held an expert workshop on the productive uses of renewable energy (17). The fact that the traditional concept of productive uses as motive power for farms is under scrutiny was revealed as the assembled international experts grappled with developing a working definition of productive uses. In the end they settled on the following definition: “In the context of providing modern energy services in rural areas, a productive use of energy is one that involves the application of energy derived mainly from renewable resources to create goods and/or services either directly or indirectly for the production of income or value” (17). It should be noted that the above definition is specifically for renewable energy; however, it can apply to energy derived from all sources. The workshop participants admitted that the meaning of productive uses of energy in the context of human development is difficult to establish. They felt that a use of energy that is instrumental in bringing about an increase in income is clearly a productive use. They also felt that the use of energy for increasing education and/or life expectancy is also a productive use; however, the impact that energy can have on these two is an indirect one. They argued that educated and healthy people will possess greater potential for income generation than a comparatively unhealthy and uneducated people. Thus, uses of energy to enhance education and life expectancy should be considered productive uses. However, some argue that applications of energy for home lighting and entertainment cannot be considered as productive applications, because even though they improve the quality of life, their linkages to the Human Development Index are less obvious and almost impossible to quantify. In a reviewof renewable energy markets Martinot et al. (18) use a definition similar to the one developed by the GEF/FAO workshop. Both not only include the uses of energy that have a positive impact on income generation, but also include the uses of energy for indirect social benefits such as education and health. Finally,K. Kapadia, in an unpublishedWorld Bank paper (19), cites three primary reasons for the emphasis on productive uses of energy: maximization of the economic and social benefits, catalyzed by access to energy; facilitation of the Millennium Development Goals; and improving the economic sustainability of rural electrification projects and renewable energy markets. Although all of the above-mentioned reasons for choosing the definition of productive uses are extremely pertinent, they preclude a broader understanding of what is meant by development. Amartya Sen (20) stresses the importance of thinking of development as the process of expanding the real freedoms that people enjoy. Specifically, he notes that the growth of individual incomes is important “as means to expanding the freedoms enjoyed by the members of the society.” In addition, he provides a wide list of freedoms, e.g., political freedom, opportunities to receive basic education, opportunities to receive health care, and freedom to participate in the labor market. It is often asked, he says, whether these freedoms are indeed conducive to development. This question, however, unfortunately misses the point that these very freedoms represent what development aims to achieve. In the context of energy, many of the uses of energy that are seen as consumptive (e.g., home lighting or television) in fact may be uses that help achieve the goal of freedom allowed by development. For instance, television viewing is considered traditionally as a consumptive or unproductive use of electricity. However, a recent study in Bangladesh revealed that women in households with electricity were much more aware about gender equality issues than women in households without electricity. Furthermore, these women cited the television as their chief source of information for gender equality-related knowledge (7). In the discussion above on the definition of productive uses of energy, energy projects that have a positive impact on education and health are included because improved health and education increase people’s incomes. A broader understanding of development would suggest that improved health and education are goals and ends in themselves. This is not to suggest that an emphasis on income generation is misplaced. However, if the only productive uses of energy are those that facilitate income generation, then any use of energy which does not must therefore be an unproductive use. Although energy professionals and specialists may understand that “productive uses of energy” is mere substitute nomenclature for “income-generating uses of energy” and does not in any way pass a value judgment on the “unproductive uses of energy,” some may mistakenly believe that only energy projects that increase income are valuable. Thus, it may be worthwhile to consider revising the nomenclature for income-generating uses of energy from “productive uses of energy” to what they really are, namely, “income-generating uses of energy.” Quantifying the impact of energy services on human development is not easy. However, a lack of quantitative data does not suggest the absence of a relationship but rather the need for further analysis and research. The next section discusses the impact that modern energy services can have on achieving the development goals in rural areas of developing countries.

| − | == LINKING OF ENERGY WITH DEVELOPMENT GOALS ==
| |
| − | | |
| − | The energy sector has a significant and productive role to play in achieving the goals related to income and poverty, education, health, and gender issues. More than half of the world’s population and more than 70% of the world’s poor are found in rural areas (21). Energy access can have a substantial positive impact on rural growth and livelihoods. In terms of economic development, it provides the basis for improving productivity by facilitating income generating activities and improving the business climate. In terms of human development, the energy sector can assist in reducing child mortality, maternal mortality, and other diseases by facilitating better health services. It can also encourage the development of higher literacy rates, gender equality, and women’s empowerment. It is not surprising that a number of statistics show a very strong association between increasing commercial energy consumption and human welfare. The MDGs (22) adopted by the UN member states commit the international community to human development and are key to sustaining social and economic progress in all countries. These goals are now almost universally accepted as a framework for measuring developmental progress. The MDGs seek to (23) eradicate poverty and hunger; achieve universal primary education; promote gender equality; empower women; reduce childhood mortality; improve maternal health; combat HIV/AIDS, malaria and other diseases; ensure environmental sustainability; and develop a global partnership for development. TheUNMillennium Project, which offers a practical plan to achieve the MDGs, has also recognized the importance of energy services. It has mentioned the provision of electricity for all schools and hospitals as one of the quick-win interventions that can be implemented immediately and has the potential to bring vital gains in well-being to millions of people (24). Table 1 is a modified version of Kapadia’s diagram, which depicts the association between energy and the MDGs (19).

| − | == Energy and Poverty ==
| |
| − | | |
| − | Energy services can help reduce poverty and raise incomes in a variety of ways. The traditional thinking about the productive uses of energy considers only the impacts on farm incomes by substituting machines for animal and human labor. However, energy services impact incomes in other ways too, such as saving time and resources, indirect benefits due to lighting and communication, and numerous other positive impacts on the nonfarm business environment. An expanded definition of the productive uses of energy would provide a greater emphasis on these benefits of energy. Electric-powered farm equipment has tremendous benefits for rural farm incomes. As discussed above, farm machinery, such as water pumps, fodder choppers, threshers, grinders, and dryers, increase average yields per acre, improve cropping intensities, are more dependable, increase cost efficiency and productivity, decrease labor time consumed, increase areas for cultivation, and result in higher crop growth. Several studies have documented these benefits (25, 26). One such study in India (25) demonstrates that the addition of an electricpumpto a typical farm without electricity can result in an approximate income gain of about 11 thousand rupees (Rs) annually. This compares quite favorably to the farmers’ electricity expenses (excluding electric pump capital expenditures), which average between 2 and 3 thousand rupees per year. Given existing agricultural subsidies, an irrigation pump appears to be a good investment for most small, medium, and large farmers with available groundwater resources. As indicated in Table 2, the same may not be true for marginal farmers, who gain only about 5600 Rs, as this sum may not cover capital costs. Therefore, it is quite reasonable that most of the farmers in this group have not yet invested in irrigation. Apart from raising farm incomes, modern energy services can improve the more informal aspects of rural incomes by reducing much of the necessary daily drudgery that pervades the lives of the rural poor. For example, the rural poor spend a considerable amount of time each day collecting fuelwood, dung, and water. Because biofuels are a poor source of energy (particularly for an activity such as cooking), they consequently have to be collected in large quantities. If the rural poor had access to improved stoves and modern cooking fuels, this time could be spent on income-generating, educational or other activities. On the extreme end of the spectrum, studies in South Indian villages have revealed that families spend 2–6 hours each day collecting 10 kilograms of wood over distances of 4–8 kilometers (27). A survey in the Himalayas (27) found that although the hilly areas of Nepal provided an abundant supply of fuelwood,women still had to spend more than an hour each day collecting biomass (28, 29). The survey also revealed that the amount of time they were able to spend on agricultural activitieswas reduced likewise (compared to other people who were not dependent on these fuels). Surveys in Africa have shown similar results (30). Some evidence from India suggests that even if households continue to cook using biomass fuels, lighting enables timesaving food preparation (31). Table 3 illustrates the amount of time and effort families spend gathering fuelwood each day.

| − | Time is not the only precious resource that is wasted by the rural poor owing to a lack of modern cooking fuels. Using dung and crop residues as a fuel reduces the amount available for use as a fertilizer for growing crops, thus reducing income from crops. The dung used as fuel in India would be worth US$800 million per year if it were used as fertilizer (32, 33). Also, the importance of lighting and the many benefits that it provides is oftentimes ignored. Without lighting, livelihood activities cannot be continued beyond daylight hours, thereby reducing the total number of productive hours available. If the rural poor had access to lighting, they could work in the evenings and nights. For example, some poor Indian households that operate small cottage industries increased their income by 10 Rs per day using light to extend their productive hours after nightfall (34). In Indonesia (35), solar home systems provided lighting, which not only had a direct impact on income-generating activities such as office and store hours but also on activities related to household chores. Another often overlooked impact is the facilitation of information and communication technologies. Rural energy services allow farm and nonfarm sectors access to modern communication, enabling them to receive accurate and current market prices. Lack of adequate information hurts sound business decision making and lowers income. For example, telephones in rural Thailand have enabled farmers to check prices in Bangkok regularly, significantly increasing their profits (34). Also, in India, the “e-choupal” initiative has succeeded in providing farmers with access to Internet-enabled computers, which helps them obtain current information on market prices and good farming practices and allows them to order agricultural inputs. This initiative has resulted in improvements to the quality of their produce and also ensures that they receive better prices for their produce (36). All of the above-mentioned benefits of improved energy services result in an improved business environment for small farm and nonfarm businesses. An example of the links between productivity and electricity is provided by a recent study in the Philippines, which found that small home businesses were more active in areas with electricity and made a greater contribution to family income than those in areas without electricity (see Table 4). Overall, 25% of households with electricity operated a home business, compared to about 15% of the households without electricity (12). The businesses with electricity, furthermore, were more productive than those without electricity. Most of these businesses were small general stores. Bundling the delivery of electricity with other services or coordinating rural electrification with other development programs has been shown to magnify its effect on income (37). A household survey in India, for instance, revealed that while both education and electricity can result in higher nonfarm income, when the two services are delivered together the effect is amplified by as much as 2.3 times (or 25,000 Rs of annual household income) (6). The traditional definition of productive uses of energy does not take into account these types of synergies.

| − | == Education ==
| |
| − | | |
| − | Modern energy services can have a positive impact on the time children spend at school and also improve the quality of the schools and the teaching. Electricity also provides lighting for rural homes, which increases the number of hours children have to study. In fact, children in rural areas are often unable to go to school because they must perform household chores and/or income-earning activities. For example, collecting cooking fuel can be an important component of a child’s daily household chores; and if children are in school, they are unable to assist the household in this activity. Similarly, children may be involved in certain income-generating activities. This income could be vital to the economics of the households, thus acting as a disincentive for the parents to send their children to school. As discussed above, lack of access to modern cooking fuels in rural areas forces villagers, often girls, to spend considerable amounts of time collecting firewood. If there is access to modern cooking fuels or better stoves (38, 39), then children need not spend hours every day collecting firewood and can take courses at school instead. In Morocco, road improvements made butane more affordable. This reduced the need for girls to collect firewood, giving them more free time and opening up new opportunities for education, work, and other activities (34). A comprehensive survey in India was able to quantify the complex relationship between electricity and education (25). Although the positive influence of rural electrification on education is fairly well established, it was found that one of the main benefits of electricity is a very high amount of quality light compared to that provided by kerosene. This high quality light in the evening creates an atmosphere in which reading is possible for adults and children, who can more easily pursue their studies.

| − | Furthermore, the likelihood of having electricity is directly related to the level of education and the level of income (see Table 5). Households in the rural energy sample with low levels of income earn about 13 thousand rupees per year and only 30% of them have electricity. This contrasts with close to 30 thousand rupees annually for the more than 80% of households that have electricity and have an adult with a high school education. Particularly interesting was the finding that with every year of education, electricity seems to have a greater impact on income compared to those households without electricity. In other words, the combination of electricity and education has a greater effect on income than each variable taken separately. This finding has potentially important policy implications because it implies that education and electricity are mutually supporting programs. Providing education without electricity is not going to have as much impact as providing education with electricity. Similarly, providing electricity by itself without schools or other educational facilities will not have as much impact as having both of them present in a community. This is supported by a study in Peru that found the bundling, or joint provision, of services was very important in creating positive impacts and increasing returns. To illustrate, the study found, in an analysis of identical households, that those households with access to basic services such as electricity and water “had a significantly higher growth rate of per capita consumption than households that did not have such access” (37). Rural schools throughout the developing world typically lack electricity and clean fuels. Many development assistance programs will pay to build school houses and provide books, teaching materials, and basic furniture, but electricity is rarely part of the package. With modern energy, these schools can much better serve the needs of students and their families by providing space heating, clean water, good meals, and educational facilities that include decent lighting, audio/visual equipment, computers, and information and communication facilities. The use of electricity, modern fuels, and thermal energy services for schools is described in a detailed manual (40) from the National Renewable Energy Laboratory. Electricity and clean water are also essential services if schools are to offer decent living and working conditions for teachers. Retaining qualified teachers in remote rural areas is a challenge. For example, there is an ongoing crisis in teacher retention faced by the Papua New Guinea Department of Education and the various Provincial Divisions of Education. At present, there are approximately 36,000 primary, elementary, and secondary school teachers posted throughout the country. Over 90% of the teachers are in rural locations and serve the predominantly rural population. Most primary and elementary school teachers have little or no provision for power supply. Primary schools in particular typically do not have electricity or communications, and teachers posted to these schools and their families suffer from a lack of basic amenities. Not surprisingly, poor teacher retention directly contributes to low levels of access to education and poor educational outcomes. [[Image.Relationship]]

| − | An example of howthis problem is being addressed is the proposedWorld Bank and GEF-assisted Teacher’s Solar Lighting Project in Papua New Guinea that will provide a modest financing package, making the purchase of solar lighting kits affordable for teachers and eventually for health workers and the general public. It is intended to improve delivery of education in rural Papua New Guinea through longer retention of teachers posted to remote areas. The project will provide the financial remediation necessary for the PNG Teachers Savings and Loan Society to offer long-term (five-year) fixed-rate loans that make purchase of a Solar House Lighting kit by school teachers possible (41). Electric lights in schools and homes permit evening study and classes. These greatly encourage adult education because adults are busy during the day. Educated adults, especially women, ensure educated children (42). Lighting also allows for a reduction in household accidents such as paraffin poisoning and burns associated with other commonly used fuels such as kerosene. According to some estimates, in Sri Lanka, one person dies every two days as the result of burn injuries associated with unsafe bottle lamps (43). A study in the Philippines examined the social and economic impact of rural electrification (12). The most important finding was the clear link between electricity and education. Rural households perceived electricity to be important for children’s education because it improved study conditions during the evening (see Table 6 for details). This was borne out by the increased number of hours spent by both children and adults reading in rural homes, where electricity was available. Children from electrified households gained about two years in educational achievement over children from nonelectrified households. A household survey in Vietnam produced similar results (44). Distance education (45, 46) is widely used in secondary schools (grades 7–9) throughout Mexico. The Telesecundaria program provides education to children who live in rural and indigenous communities where access to modern education services is limited. The educational program uses 16-minute televised lessons transmitted from Mexico City via the EDUSAT satellite. Rural teachers use the broadcast in combination with related texts and other teaching materials for a total educational segment of 48 minutes. The television sets are used for about 2 hours during each school day. Both grid electricity and photovoltaic (PV) power systems are used to ensure reception by all communities.

| − | The Mexican program is not just about energy; it is a comprehensive distance education program developed over more than three decades, and it is a major initiative in bringing the possibility of universal primary and secondary education to Mexico. Other developing countries are using various energy-enabled methods for distance information and education, including both low-cost radio (e.g., Mali) and television. The integration of modern energy with schools and effective curricula is emerging as an essential approach to achieving improved education in rural areas of developing countries. The evidence of correlation between electricity and education is strong, but we must caution that the difficult issue of causality has not been fully resolved. There is fairly strong evidence that electricity is related to improvement in school attendance, literacy, and level of education, but this could be caused by the decision of educated households to adopt electricity as well. These are issues that require further investigation and may be assisted by the inclusion of energy questions in national multisector surveys, a topic addressed below.

| |
| − | clinic has a live-in doctor, the systems include a television and radio.
| |
| − | It is for some of these reasons that maternal mortality rates tend to be lower
| |
| − | in urban areas than in rural areas in most parts of the world because urban residents
| |
| − | have easier access to appropriate medical services. One study illustrates
| |
| − | the beneficial effects that electricity can have on an area’s infant mortality rate. As
| |
| − | seen in Figure 1, the infant mortality rate in electrified Bangladesh households was
| |
| − | 4.27%, whereas nonelectrified households in electrified villages and nonelectrified
| |
| − | villages experienced rates of 5.38% and 5.78%, respectively. For further perspective,
| |
| − | the infant mortality rate in households with electricity is 25% less than the
| |
| − | national average (5.7%) and 35% less than the national rural average (6.6%). The
| |
| − | study’s estimates show that if access to electricity is expanded to 100% of rural
| |
| − | households, the annual number of infant deaths that could be avoided would
| |
| − | number roughly 36,818, i.e., a savings of 101 infant deaths everyday (7).
| |
| − | Access to modern energy services also can improve access to clean water, and
| |
| − | this, in turn, can make a significant difference in the fight against all kinds of
| |
| − | diseases (54). Energy allows the use of mechanized pumps to tap water from deep
| |
| − | wells, and energy can be used to boil or filter available water resources to make it
| |
| − | safe for drinking. Energy for pumping and treating raw water provides numerous
| |
| − | health benefits for communities as well. And, by reducing the cost of boilingwater,
| |
| − | access to modern cooking fuels not only improves hygiene but also reduces deaths
| |
| − | from diseases such as diarrhea.
| |
| − | Exposure to biomass smoke is a significant cause (55) of health problems, such
| |
| − | as acute respiratory infections, chronic obstructive lung diseases, lung cancer, and
| |
| − | pregnancy-related outcomes (56). Indoor air pollution affects children and women
| |
| − | the most. In fact, indoor air pollution is estimated to kill 2 million women and children
| |
| − | every year: There are about 500,000 deaths in India, roughly the same in China,
| |
| − | with the other million in other developing countries (57). It is also estimated that indoor
| |
| − | air pollution causes 500 million incidences of illness each year amongwomen
| |
| − | and children in India alone (58). In Nepal and India, studies of women exposed to
| |
| − | biomass smoke—but who did not smoke themselves—found that their death rate
| |
| − | from chronic respiratory disease was similar to that of heavy smoking males (59).
| |
| − | [[Image:Comparison]]
| |
| − | | |
| − | The exposure to smoke is quite high in households that cook with biomass fuels
| |
| − | in traditional stoves. For instance, a study in the Guatemala highlands (see Table 7)
| |
| − | indicates that households using open fires for cooking have average particulate
| |
| − | exposure levels of over 700 micrograms per cubic meter of air over a period of 24
| |
| − | hours. For households with an improved stove (plancha) or those that use LPG,
| |
| − | the exposure levels are 100 to 200 micrograms per cubic meter. As a reference, this
| |
| − | level can be compared to the United States Environmental Protection Agency’s
| |
| − | recommended maximum exposure level of 50 micrograms. Therefore, developing
| |
| − | country households that used open fires or three stone stoves have very high levels
| |
| − | of exposure to particulates.
| |
| − | There is strong evidence of causal linkage between biomass combustion emissions
| |
| − | and acute respiratory infections in children (60, 61). Children are particularly
| |
| − | vulnerable because they spend a lot of time indoors close to the women who are
| |
| − | doing the cooking. A study in the Gambia, for example, examined the health of
| |
| − | 500 children under five years old. It found that girls, who were carried on their
| |
| − | mother’s backs as they cooked in smoky huts, were six times more likely to develop
| |
| − | acute respiratory illness than other children (62).World Health Organization
| |
| − | figures indicate that 20% of the 10.9 million deaths of children under five years old
| |
| − | in 1999 were due to acute respiratory infections. In Bangladesh, a study found that
| |
| − | a child’s exposure to indoor pollution could be halved simply by increasing their
| |
| − | time spent outdoors from 3 to 6 hours per day and by concentrating this outdoor
| |
| − | time during peak cooking periods (63).
| |
| − | Information and communication facilities also play a crucial role in improving
| |
| − | health. Rural health clinics benefit from radio-telephone communications capabilities,
| |
| − | including single-side-band radios, two-way radios, cellular phones, and satellite
| |
| − | phones. In Cuba, clinic electrification resulted in significant health improvements
| |
| − | in local communities. However, owing to the remoteness of clinics, doctors
| |
| − | had no way to communicate with ambulances or hospitals. Radio communications
| |
| − | were added to each clinic. Of the 170 clinics, 130 have radiotelephones, allowing
| |
| − | them to communicate with hospitals in the larger towns. The radiotelephones
| |
| − | have already saved numerous lives and have been used for many purposes, including
| |
| − | during hurricanes and floods to request ambulance or helicopter assistance;
| |
| − | to inform relatives of the condition of a patient in a hospital; to inform hospitals
| |
| − | about the status of vaccination campaigns; to ask for specific medicines needed by
| |
| − | the clinic; and to solicit help from medical specialists. Importantly, the communications
| |
| − | equipment adds only slightly to the cost of the total PV system.
| |
| − | Apart from having direct impacts on health (as described by the examples
| |
| − | above), energy services also provide indirect impacts on improving health by increasing
| |
| − | literacy, reducing malnutrition, and promoting women’s empowerment.
| |
| − | For instance, a rise in women’s literacy and education has a strong impact on
| |
| − | reducing child mortality, maternal mortality, and HIV/AIDS. Educated women
| |
| − | take better care of children and increase a child’s chances of surviving. Grant in
| |
| − | “The State of the World’s Children” (64) has shown the relationship between female
| |
| − | literacy rate, contraceptive prevalence, the crude birth rate, and the maternal
| |
| − | mortality rate. The higher the female literacy rate, the lower is the maternal mortality
| |
| − | rate. The education of young people merits the highest priority in a world
| |
| − | afflicted by HIV/AIDS because education is the most effective—and the most
| |
| − | cost-effective—means of prevention (22).
| |
| − | Increased energy access can have an indirect impact on reducing malnutrition.
| |
| − | About 95% of staple foods need cooking before they can be eaten. Thus, lack
| |
| − | of access to energy may render some, otherwise edible, products inedible and
| |
| − | increase hunger. Malnutrition plays a role in more than half of all child deaths.
| |
| − | Experts agree that malnutrition leaves many women unable to meet the physical
| |
| − | demands of pregnancy (65).
| |
| − | | |
| − | ==Gender Equality andWomen’s Empowerment==
| |
| − | | |
| − | Lack of women’s empowerment has a direct impact on women’s health issues. It
| |
| − | is not an exaggeration to say that a maternal death is the outcome of a chain of
| |
| − | events and disadvantages throughout a woman’s life (66). A UNICEF publication
| |
| − | (67) titled The Lesser Child highlights the disadvantages of being born a female.
| |
| − | For example, girls are likely to be breast fed less often and for a shorter period
| |
| − | of time than boys, resulting in malnourishment from the beginning of their lives.
| |
| − | They also are subjected to heavy work both within and outside the house at an
| |
| − | early age and, when ill, are less likely to receive medical help. Energy services in
| |
| − | rural areas can have a significant impact on women’s empowerment (one of the
| |
| − | MDGs), thus indirectly impacting women’s health issues too. | |
| − | Energy projects are often seen as having no impact on gender equality (68),
| |
| − | however, as it is assumed that energy services impact men and women in similar
| |
| − | ways. This assumption does not reflect reality in most developing countries.
| |
| − | Consequently, several energy projects have not been as successful as they should
| |
| − | have been because they failed to recognize the differences in energy usage patterns
| |
| − | between men and women (69).
| |
| − | As a matter of fact, rural markets in developing countries often do not provide
| |
| − | appliances that cater towomen’s needs. Although these markets stock leisure items
| |
| − | such as televisions as well as video and audio players, they do not provide laborsaving
| |
| − | cooking devices for women, e.g., mixers, grinders, and cookers. One of the
| |
| − | reasons this occurs is that men are the decision makers; hence, markets are biased
| |
| − | | |
| − | [[Image:Hours]]
| |
| − | | |
| − | toward goods that serve their interests.Women benefit from televisions and radios
| |
| − | too, but many of the labor-saving devices that are of greater benefit for women are
| |
| − | not considered a priority (10).
| |
| − | Many of the benefits that stem from modern energy services disproportionately
| |
| − | benefit women more than they benefit men (31). This is largely true because it is
| |
| − | women and girls who spend the most amount of time and effort cooking, collecting
| |
| − | water, and collecting fuelwood and other biomass resources (see Table 8 for an
| |
| − | example). Thus, any improvement in energy access will disproportionately benefit
| |
| − | them. By reducing the time women must spend cooking and collecting water,
| |
| − | electricity allows women and children to spend more time on educational, social,
| |
| − | and income-generating activities. This additional time can have a dramatic effect
| |
| − | on a woman’s level of education, health, economic opportunities, and involvement
| |
| − | in community activities (70).
| |
| − | Limited access to modern energy remains an issue of gender equity in much
| |
| − | of the rural developing world because 70% of all poor are women. A study of the
| |
| − | impact of electricity on rural women in India showed that women from households
| |
| − | with electricity had more time for leisure activities than women from households
| |
| − | without access to electricity. There also is evidence that suggests the probability
| |
| − | that a woman will read is very strongly related to the presence, or absence, of
| |
| − | electricity in the home. In fact, regardless of income level, virtually no reading
| |
| − | takes place in households without electricity.
| |
| − | The Indian experiencewas mirrored in Mali (71), where modern energy services
| |
| − | derived from a multifunctional platform project showed that after the implementation
| |
| − | of the project women were spending less time milling cereals and dehusking
| |
| − | rice. They also were generating greater revenue from the sale of agricultural goods
| |
| − | and foodstuffs and were producing and consuming greater amounts of rice. Perhaps
| |
| − | most relevant to the subject of women’s empowerment is that the total proportion
| |
| − | of girls completing primary school increased as did the girl-to-boy ratio in primary
| |
| − | schools. Additionally, from a health perspective, the number of prenatal visits that
| |
| − | women made to health clinics also increased.
| |
| − | The successful integration of renewable energy with economically productive
| |
| − | uses in the rural Philippines is providing income to many women at a small coconut
| |
| − | development cooperative (72). This enterprise employs 200 families; 90% of
| |
| − | the employees are women. Not only have employees doubled their household incomes,
| |
| − | but previously unemployed rural women are now earning a regular income
| |
| − | and, in many cases, have become the principal wage earners. Rural women have
| |
| − | been empowered by becoming bona fide (with voting privileges) members of the
| |
| − | local coconut cooperative. The Philippine Government and others are supporting
| |
| − | replication of this activity in other coconut growing areas of the Philippines.
| |
| − | In Bangladesh, a study revealed that women in households with access to electricity
| |
| − | were much more aware of gender equality issues than women in houses
| |
| − | without access to electricity. Barkat’s case study of Bangladesh (7) provides a
| |
| − | “women’s knowledge score of gender equality issues” for electrified and nonelectrified
| |
| − | households in electrified villages and nonelectrified houses in villages
| |
| − | without electricity. Figure 2, demonstrates the effect of electricity on women’s
| |
| − | empowerment through a combined knowledge score based on three indicators:
| |
| − | (a) women’s freedom in mobility, (b) participation in the family decision-making
| |
| − | process, and (c) knowledge about gender equality issues. Women in households
| |
| − | with electricity had a higher empowerment score (0.662) than women in nonelectrified
| |
| − | households in both electrified and nonelectrified villages (0.533 and 0.499,
| |
| − | respectively).
| |
| − | The same study also found that poor women in electrified households were
| |
| − | more knowledgeable (79%) about gender equality issues than even the rich in the
| |
| − | nonelectrified villages (64%). This indicates that household access to electricity
| |
| − | can greatly improve a poor woman’s knowledge of gender issues.
| |
| − | Figure 3, illustrates the sources women in both electrified and nonelectrified
| |
| − | households use to acquire knowledge about gender equity issues. Barkat notes that,
| |
| − | “Electricity has contributed spectacularly to knowledge-building about selected
| |
| − | gender equality issues” (7). Indeed, his statement is validated by Figure 3, which
| |
| − | shows that 64% of women in electrified households reported television as their
| |
| − | main source of knowledge about these issues.
| |
| − | It can be concluded reasonably, therefore, that women in electrified households,
| |
| − | compared to those without, are more aware and knowledgeable about the selected
| |
| − | gender equality issues and that electricity (via television) can play an important
| |
| − | role as a primary source of this knowledge. This has important implications for the
| |
| − | definition of productive uses of energy. In the traditional thinking about productive
| |
| − | uses of energy, use of energy for television is considered a leisure or nonproductive
| |
| − | use. However, if watching television encourages gender equality and gender
| |
| − | equality is one of the goals of development, then energy used for television is
| |
| − | energy used productively Public lighting improves women’s safety and encourages evening community
| |
| − | and commercial activities. Clean cooking fuels minimize indoor air pollution and
| |
| − | the associated morbidity and mortality of women.Women are at greatest risk from
| |
| − | indoor air pollution because of their gender roles, household responsibilities, and
| |
| − | behavior (e.g., cooking and spending a lot of time indoors). Modern energy services
| |
| − | (e.g., from multifunctional platforms) can increase agricultural productivity
| |
| − | and women’s incomes. Electricity and fuels for lighting, refrigeration, entertainment,
| |
| − | and a host of other purposes permit women to develop small enterprises and
| |
| − | increase their income and social power (9).
| |
| − | In conclusion, an updated approach to the productive uses of energy would
| |
| − | emphasize that energy services should be part of a suite or package of rural infrastructure
| |
| − | services that together can provide a base for substantial economic and
| |
| − | social development. For instance, it was found in Peru that when the infrastructure
| |
| − | includes electricity, water, and other development programs the various parts actually
| |
| − | work together rather than separately to promote economic growth (37). The
| |
| − | result is that the causal effects of electricity and other energy services are sometimes
| |
| − | hard to disentangle from other causes. However, this is really an empirical
| |
| − | issue for further research rather than an argument against the relationship between
| |
| − | energy and rural productivity.
| |
| − | | |
| − | ==EFFECT ON PUBLIC POLICY==
| |
| − | | |
| − | The most obvious impact of considering all the productive uses of energy is to
| |
| − | realize that even though the MDGs do not explicitly mention energy, without the
| |
| − | provision of energy services, the MDGs cannot be achieved (see Table 1 for MDG
| |
| − | linkages). This has strong implications for public policy. Development strategies,
| |
| − | whether formulated by the developing countries themselves or by international
| |
| − | development institutions, must include a greater role for rural energy. In the past,
| |
| − | energywas either assigned a marginal role or not mentioned at all in important strategy
| |
| − | documents. Such an approach will only serve to repeat the mistakes of the past.
| |
| − | Energy services also cannot be thought of in isolation. Changes in the understanding
| |
| − | of the productive uses of energy for rural development have meant that
| |
| − | public policy also must consider the following: An emphasis on simply providing
| |
| − | electricity coverage in rural areas without adequate forethought to opportunities for
| |
| − | business development and poverty reduction is not only undesirable, but in the long
| |
| − | run is unsustainable as valuable resources will be wasted. Moreover, promotion
| |
| − | of productive uses, in addition to its poverty reduction impacts, can also improve
| |
| − | the efficient utilization of energy infrastructure. For example, a rural electrification
| |
| − | project in Indonesia included a component to promote rural business services
| |
| − | by targeted marketing interventions and price incentives and also addressed information
| |
| − | constraints and business needs of small enterprises in rural areas. The
| |
| − | rural business service program demonstrated that these promotional efforts led to
| |
| − | better daytime utilization of utility electricity generation and distribution assets.
| |
| − | In fact, the program supported 66,000 rural enterprises and led to an increase in employment of 22,000, as well as an increase in electricity consumption by these
| |
| − | enterprises of 180 GWh/year (73).
| |
| − | Energy services, to be most effective, have to be applied in a way that they
| |
| − | improve the delivery of services from various other sectors such as health, education,
| |
| − | information, and communication. This in turn has several implications. To
| |
| − | a certain extent, the work on productive uses of energy has overconcentrated on
| |
| − | the role of electricity. This is not to diminish the importance of electricity, but to
| |
| − | improve maternal health, for example, improved cook stoves and modern cooking
| |
| − | fuels are needed to reduce indoor air pollution. Also, it is important that public
| |
| − | policy recognizes the interdependence of the various sectors by employing a multisectoral
| |
| − | approach. For example, in the case of India, this suggests that the rural
| |
| − | electrification program should have a broader focus—one that seeks to improve
| |
| − | not only the supply and quality of electricity to households, businesses, and farms,
| |
| − | but also to improve access to services (6).
| |
| − | This broader focus implies that within the developing countries, as well as in
| |
| − | the international development institutions, development professionals need to have
| |
| − | greater cross-sectoral interaction and competence. Energy professionals need to
| |
| − | provide greater outreach by engaging planners and implementers within other sectors.
| |
| − | By doing so, this will help ensure that an understanding of the important role
| |
| − | of energy in delivering services ranging from health to education to communication
| |
| − | is held among all professionals across all sectors (71, 73).
| |
| − | Although energy professionals often maintain that their colleagues from the
| |
| − | health and education sectors, for example, do not grasp the importance of energy
| |
| − | services, more often than not they themselves are guilty of not having made an
| |
| − | attempt to understand the education and health sectors. To be sure, it is of critical
| |
| − | importance that a better understanding of the linkages between energy and other
| |
| − | sectors be found. In spite of anecdotal evidence, there is a lack of sufficient quantitative
| |
| − | data on this aspect. However, it is important to emphasize that the lack of
| |
| − | quantitative data does not indicate the absence of linkages but rather only indicates
| |
| − | the need to study these linkages further.
| |
| − | Thus, it is important to improve and systematize the collection of information
| |
| − | on uses of energy and its impact on income generation, health, and education (86).
| |
| − | Often, energy is represented only by a handful of questions in national multisector
| |
| − | development surveys. As a consequence, it is difficult to establish or understand
| |
| − | the relationship between energy, productive uses, and development because there
| |
| − | are few national surveys that contain information about energy and other social
| |
| − | indicators such as health and education.
| |
| − | | |
| − | ==CONCLUSION==
| |
| − | | |
| − | In light of the increasing emphasis on the importance of education, gender, and
| |
| − | health for development, the energy practice needs to reevaluate its view on productive
| |
| − | uses of energy. The emphasis on motive power that leads directly to increasing
| |
| − | incomes is an important component of energy and productive uses. However, in this review, we argue for a much broader approach. The very purpose of development
| |
| − | is to create a world full of healthy, educated, and socially equal people.
| |
| − | Although income generation is an important means toward this goal, it must be
| |
| − | recognized that any use of energy that contributes toward education, health, and
| |
| − | gender equity should be considered a productive use of energy.
| |
| − | The ways in which energy contributes to the improved productivity of rural
| |
| − | populations are both many and varied. Energy services can improve the delivery
| |
| − | of health and educational services by providing lighting, refrigeration, heating,
| |
| − | and modern communication. New energy services can reduce the amount of laborintensive
| |
| − | time that rural women and children spend on collecting fuelwood and
| |
| − | performing household chores. This extra time can be used on more productive
| |
| − | activities, including the pursuit of educational, income-generating, and leisure
| |
| − | activities. Improved cooking fuels and stoves can alleviate health problems—
| |
| − | and even reduce deaths—related to indoor air pollution from traditional ways of
| |
| − | cooking with biomass. Generally, everyone agrees with the notion that healthy
| |
| − | people are more productive.
| |
| − | Broadening the definition of productive uses of energy is important for a better
| |
| − | understanding of how energy is related to development. Even motive power is a
| |
| − | means to an end and not an end in itself. Machines must be used by educated and
| |
| − | healthy people to be effective in promoting development and improving income.
| |
| − | Also, energy in the context of failing schools, poor health facilities, and poor water
| |
| − | supply will not lead to development. However, without energy there are limits
| |
| − | to any type of growth in rural areas. This suggests an urgent need to examine
| |
| − | the critical linkages between energy and women’s empowerment, education of
| |
| − | children and adults, health, and income generation without past preconceptions of
| |
| − | the productive uses of energy.
