Non-conventional or renewable energy comes from sources such as solar, wind, geothermal, biomass, hydro, and ocean thermal energy. Solar energy comes from the sun and can be used to generate electricity through photovoltaic cells or provide heat through solar collectors. Wind energy harnesses the wind using wind turbines in wind farms. Geothermal energy taps into the natural heat below the earth's surface to generate electricity. Biomass includes organic matter that can be burned to produce biofuels like ethanol or biodiesel. Hydropower utilizes the kinetic energy of moving water through dams or turbines. Ocean thermal energy exploits temperature differences in ocean water to power engines.

22. Types: Natural geysers Artificial geysers NATURAL GEYSERS : In some place, the hot water comes out of the ground through cracks naturally in the form of natural geysers . ARTIFICIAL GEYSERS : In some place we can drill a hole up to the hot region and through pipes we can transfer the hot steam.
27. TYPES: USING BIOGAS Wood , seed, cattle dung, agricultural waste etc. USING BIOFUEL ethanol , methanol, gasohol etc . The higher heating value of cellulose is about 17.4 MJ/kg [1]. The estimated yield of ethanol from dry cellulose is about 0.2 kg of ethanol per kg of cellulose [2] (60 gal/ton). Since the higher heating value of ethanol is 29.7 MJ/kg of ethanol it would be 5.94 MJ/kg of the cellulose
