» Renewable Energy This refers to a renewable source of energy like wind, sun, and biomass. Wind energy, solar energy, and biogas energy along with suitable devices are used in domestic and agricultural purposes. This type of energy can be used for cooking, heating water, lighting, water distillation, water pumping, electric generation, and food processing. Renewable energy is inexhaustible in nature. Wind Energy – Electricity generation, water pumping Solar Energy – Solar lighting, solar refrigeration, solar dryers, cooker, lantern, solar still Tidal Energy – Electricity generation Biomass Energy – Pyrolysis, gasifiers, biogas Geothermal Energy – Electricity and heat production Merits – No danger of depletion Inexhaustible, reproducible in nature Power plants running on renewable energy have no fuel cost and hence, have a negligible operating cost More site-specific (used for local processing) No need for distribution and transmission of power Low energy density Do not pose a threat t...
