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.
Biomass is organic material that comes from plants and animals, and includes crops, waste wood, and trees. When biomass is burned, the chemical energy is released as heat and can generate electricity with a steam turbine.
Hydropower is the largest renewable energy source for electricity Nationally and internationally, large hydroelectric plants—or mega-dams—are often considered to be non renewable energy.
We’ve come a long way from old-fashioned wind mills.Wind energy turns a turbine’s blades, which feeds an electric generator and produces electricity.
Distributed solar systems generate electricity locally for homes and businesses, either through rooftop panels or community projects that power entire neighborhoods.
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.
