Background
Renewable Energy is “energy derived from natural processes (e.g. sunlight and wind) that are replenished at a faster rate than they are consumed. Solar, wind, geothermal, hydro, and some forms of biomass are common sources of renewable energy." [1]
On Earth, there are three sources for renewable energy: solar radiation, heat from the Earth’s core (geothermal energy) and gravitational force resulting from planetary movements (tidal power). Energy resulting from solar radiation accounts for about 99.9% of all energy available on Earth.
Even if the renewable energy resources are distributed throughout the world, location plays a huge factor when deciding which resource should be applied and in what level of intensity. Solar and wind energy resources are intermittent in nature – this indicates that not all resources are suitable for each location, purpose or application. Site-specific analysis is hence crucial. In case of solar energy, equatorial regions are more suitable than far northern and southern regions.
Generally speaking, each location has some sort of renewable energy potential. Sometimes this potential is directly visible and at other times different resources have to be combined. However, there is almost always a way to tap nature’s vast energy supply. To find out about the potential around your area, look for renewable energy projects nearby or talk to your national institutions to access studies on different potentials.

Conclusion
- Use of renewable energy in rural remote areas of many developing countries could help farmers to increase agricultural productivity as well as to earn more money by value addition to their produces (e.g. controlled drying of fruits and vegetables, cheese production from milk, off-seasonal production of fruits and vegetables with irrigation, etc.)
- The potential for using REs in the agricultural value chain is plentiful and often has many advantages compared to conventional technologies like diesel generators.
- A high level of integration of RE into an agricultural process can lead to high efficiencies, low environmental impact and low production costs.
- There is always some sort of RE resource available in any location, it is just important to choose the adequate source or a good combination of sources.
