Answer:
Solar Energy
Wind Energy
Tidal Energy
Geothermal Energy
Biomass
Explanation:
Solar Energy
Solar energy is harnessed by converting solar energy directly into electrical energy in solar plants. Photosynthesis process carries out this process of conversion of solar energy. In photosynthesis, green plants absorb solar energy and convert it into chemical energy.
Wind energy
Wind energy describes the process by which wind is used to generate electricity. As the wind increases, power output increases up to the maximum output of the particular turbine. Wind farms prefer areas, where winds are stronger and constant. These are generally located at high altitudes.
Biomass energy
Biomass is the organic matter that originates from plants, animals, wood, sewage. These substances burn to produce heat energy which then generates electricity. The chemical composition of biomass varies in different species but generally, biomass consists of 25% of lignin, 75% of carbohydrates or sugar. Biomass energy is also applicable for cooking, lighting, and generation of electricity.
Tidal energy
Tidal power is a form of hydropower that converts the energy of tides into electricity. In areas where the sea experiences waves and tides, we can generate electricity using tidal power. India may take up “ocean thermal level conversion” by which it will be able to generate 50,000mW of electricity to meet the power requirements.
Geothermal energy
Geothermal energy is the heat energy that we get from hot rocks present in the earth’s crust. So Geothermal wells release greenhouse gases trapped within the earth and but these emissions are much lower per energy unit than the fossil fuels. This energy generally involves low running costs since it saves 80% on fossil fuels.
