Access to source of energy is still a major problem to sustainable development in many parts of Nepal. Large areas of hilly and mountain region are still not electrified and where there is electricity it is often unreliable or prohibitively expensive.
The best alternative form of energy is renewable energy. Renewable energy can be obtained form various source like sunlight, wind, water, biomass, geothermal etc. Solar energy is one of the best source and can be received from any part of the earth. Solar energy technology cab be simply divided into two categories: solar thermal technology and solar photovoltaic(PV) technology. Wind Energy can also be best alternative for such areas where adequate flow of wind is available. A wind turbine produces power by converting the force of wind (kinetic energy) acting on the rotor blades (rotating energy) into torque (turning force or mechanical energy). This mechanical energy is used within a generator to produce electricity.

Biogas energy is very popular and useful in village areas of Nepal. Biogas is a form of clean cooking mechanism, an eco-friendly sustainable source of renewable energy, economically and environmentally compatible to use.  It is produced out of organic waste and can be used for multiple purposes i.e. thermal, electric etc. The slurry that the biogas system produces is a convenient source of organic fertilizer which is a key factor on multiplying the agro-productions maintaining the environmental sustainability.
