Access to Modern Energy

Energy Access Trends

Energy access represents a crucial dimension to the issue of poverty. Without energy, economies cannot develop, as energy is a key input to all economic sectors such as industry, commerce and agriculture, and important for the provision of social services such as education and health. Relatively small amounts of energy can satisfy the basic needs of rural populations, can improve the productivity, competitiveness and employment of rural areas and have a dramatic impact on quality of life. Despite this, approximately 3 billion people, half the world's population, have no access to clean cooking energy and around 1,6 billion are without electricity provisions. The vast majority of those affected reside in rural and isolated locations which remain unreached by modern energy services and electrification programs, relying instead on traditional forms of energy. 

Defining Energy Access

The Poor People’s Energy Outlook 2010 by Practical Action has attempted to define energy access by introducing six kex energy services (lighting, cooking and water heating, space heating, cooling, access to information and communication technologies, and energy for earning a living) as well as minimum standards for “total energy access” for each service category. It furthermore proposes an “Energy Access Index” which is derived from a household’s level of energy access in the areas of household fuels, electricity, and mechanical power. A short summary of the minimum standards for energy access and the calculation of the Energy Access Index can be found at http://practicalaction.org/energy-advocacy/ppeo-energy-access-standards .

Distribution of Access

Electrification has the potential to open doors to many essential services such as refrigeration in clinics, lighting in schools and homes, battery charging and diversified livelihoods, yet over a quarter of the world's population lack access. There are over 30 countries where more than half the population are without access.

Of the 32 countries with an electrification rate of less than 50%, 26 are located in sub-Saharan Africa where the average rate is just 26%. This geographic distribution is not only evident on a national level but also within countries, where rural areas have considerably lower electrification rates. In sub-Saharan Africa the rural electrification rate is just 8%.

In South Asia the electrification rate is 60-65%. Nevertheless, the absolut number of unelectrified households is as high as in Sub-Saharan Africa. Most of these households live in India. Per capita consumption of electricity in South Asia is the lowest after Sub-Saharan Africa.

In addition to insufficient access to electricity, over 3 billion people worldwide are reliant on solid fuels, [http://www.who.int/indoorair/en/ including biomass fuels such as wood, dung, agricultural residues, and coal, for cooking. In at least 45 countries, primarily in sub-Saharan Africa and developing Asia, more than three-quarters of the population are dependent on these solid fuels. As with electrification, those in rural areas have far lower access to modern fuels and services.

Benefits of Energy Access

Energy can be a powerful vehicle for the provision of essential services such as education, healthcare and clean water. The time burden associated with essential tasks is an important signifier of energy-poverty yet energy technologies can reduce the disproportionate time spent by poor households on basic activities. Access to energy services can help communities meet basic needs and stimulate social, economic and environmental development.

Livelihood benefits

Energy access has the potential to alleviate poverty through stimulating rural livelihood options. This can occur via the establishment of new energy-based industries, creating employment in manufacture, construction and maintenance. Energy access can allow households to engage in a more diverse range of income-generating activities as well as make pre-existing activities more efficient. In particular, this diversification will make rural families far less dependent on natural resources as their sole form of income. Nearly 60% of the population in low income countries rely on agriculure, forestry and fishing for their livelihoods. This figure rises to over 90% in some countries. With the necessary infrastructure to ensure sustainability, new livelihoods developed via energy access can have a huge impact on long term poverty reduction.

Health

Modern energy access has the potential to improve health in rural areas both directly- by powering healthcare facilities- and indirectly, by providing cleaner fuel sources and reducing debilitating labor.
The inefficient combustion of solid fuels combined with inadequate ventilation contributes to poor health in many households. These high levels of indoor air pollution often result in decreased pulmonary function, particularly amongst women and children. According to the WHO, approximately 1.6 million premature deaths are attributable annually to indoor air pollution, making it the second largest environmental health risk factor in the world. Indoor air pollution is also responsible for 38 million disability adjusted lost years (DALY), where one DALY represents one healthy year of life lost by an individual due to disease or adverse health conditions, which in turn has numerous impacts on income generation, livelihoods and education.
Furthermore, this dependency on biomass resources such as fuelwood and the lack of intermediary means of transportation means that increasingly large distances are traveled with these heavy loads, often resulting in debilitating back conditions, particularly impacting women and children.
This is also having widespread implications for the natural environment in vulnerable regions, with biomass fuel sources rapidly depleting, placing even greater pressure on the poor just to meet basic needs.

Clean Water

Energy based technologies can help ensure that communities have access to one of the most basic necessities, clean water, by aiding in both the distribution and purification of water supplies. 17% of the world's population do not have access to an improved water source with this value rising to over 45% in sub-Saharan Africa.

This lack of a clean and steady water supply limits agricultural activity and results in easily preventable diseases, poor hygiene and inadequate sanitation. The World Health Organization found unsafe water, hygiene, and sanitation to be the world's largest environmental health risk factor [1]annually responsible for over 1.7 million deaths. Energy technologies such as solar, wind and hydraulic ramp pumps[2]can aid in redistributing the water supply to the areas in which it is most needed whilst application of simple solar distillation techniques can improve water purity.

Education

The impacts of energy access on education are often indirect, with one linkage being to the issue of time burden. Improved energy resources can reduce the time and labor required to achieve certain tasks such as collecting fuelwood and water as well as mechanizing many activities. This in turn could lead to increased enrolment of children in schools, since their household roles are no longer as consuming. In addition, access to lighting in the home increases the time available for study and hence may impact on achievement levels. Lighting at the schools themselves can remove restrictions on school times making night classes a viable possibility or allowing schools to double as community centers in the evenings. Electrification can also affect education infrastructure through the integration of modern resources such as computers and internet access.&

What is required to enable rural energy access

Many of the same elements necessary for any successful development intervention are applicable to the case of sustainable rural energy provisions. Developers should ensure that the technology itself is affordable and appropriate. Participation of the communities in question must be key at all stages and access to energy provisions and services should be equitable. In addition, local capacity should be built in order to ensure the long term sustainability and replicability of the scheme.

Affordability

Affordability and payment mechanisms are key considerations when assessing energy interventions. The poorest households often spend a disproportionate amount of their income on energy. Amongst those earning less than $3000 annually the percentage of total household expenditure spent on energy can be as high as 12%. In most cases it is the capital costs associated with shifting to a new energy carrier or end use technology that present the greatest barrier for poorer households. To remediate this, many payment mechanisms are possible ranging from subsidies to loans to upfront payments. These mechanisms need to be tailored to the specific needs of lower income households.

Most [3]still favor conventional centralized energy schemes such as fossil fuel plants or large scale hydro power. However, for the many residing in rural locations a smaller scale decentralized approach is far more likely to meet their needs. It is often economically unfeasible to extend the national grid to low density rural communities, particularly when combined with the relatively low energy consumption of these populations. In such situations, decentralized sources are the only feasible option. When combined with the drive for "sustainable energy" renewables become particularly attractive.

[4] i.e. energy technologies which do not supply to a national grid, can take a number of forms including diesel generators, micro-hydro schemes, wind turbines and solar photovoltaic. The most suitable technology is dependent on a combination of physical, economic and social factors.

Participation A decentralized approach to energy interventions led by local needs and contexts is important, particularly with smaller communities and rural populations. Starting with the people and not the technology can lead to improved and more widely disseminated energy technologies. Even Principle 10 of the [5] states that "Environmental issues are best handled with the participation of all concerned citizens. Each individual should have (information) and the opportunity to participate in decision making processes." Employing a participatory approach underpins every aspect of ensuring the success of an energy project.

Appropriate Technology Technology in itself is not the cure-all to rural development issues. In fact, installation of the same technology within different contexts can often yield contrasting results. There is no best-fit solution to energy needs, and carriers must be weighed carefully against the local situation, capabilities and preferences.

For example the initial focus should be on modernizing existing needs before introducing new services. In many rural areas the main household energy need is for cooking purposes. The chief use of electricity is for lighting, which, although important, tends to be a much lower priority amongst households. Despite this rural electrification is often higher on the agenda of many governments and international agencies, possibly due to the relatively high profile and kudos of electrification programs compared to cooking.

Access and Equity Access to modern energy services can potentially have a huge impact on poverty alleviation. Despite this not all energy projects have the desired effect on the communities in which they are implemented. Energy planners need to integrate social sustainability factors within projects including: the distribution of households able to access the resources; equality of access within these households; the potential marginalization of certain groups such as women, the young or old, the very poor; and the sustainability of the livelihoods promoted by energy access.

The energy needs of rural communities are not uniform. Income, cultural background, livelihood choices and family structure can all play roles in determining particular requirements and situations.

Intra-household energy use is often just as dynamic as that between households and once again a comprehension of specific needs, situations and behaviors is necessary. Women tend to bear the burden of the human energy crisis taking responsibility for activities such as pumping water, collecting firewood and other fuels, cooking and their family's healthcare (see table below). In addition there are often distinctions in access to credit or land as well as training opportunities. As a result men and women may have very different priorities regarding energy services.

Replicability

The replicability of a particular project is also key to ensuring long term success and proliferation especially in terms of the transfer of technology and knowledge to local communities. For example, has capacity been built sufficiently enough that local people are able to take responsibility for the maintenance and upkeep of the project? Have they acquired the necessary skills which will allow them to act as future facilitators on similar interventions in neighboring areas? Have local industries been developed and appropriate technologies been used such that local communities are not reliant on the import of materials?

Energy for Development

Energy access in itself is not a panacea to rural poverty issues. A successful intervention has the potential to stimulate development by modernizing existing needs and introducing new services. However the long term success of any energy project requires social sustainability to play a central role which can only be achieved by starting from the context of the users rather than the technology.
