Answer 1

Answer:

Name and describe some non-conventional sources of energy

Energy generated by using wind, solar, small hydro, tides, geothermal heat and biomass is known a non-conventional energy

• Wind - 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. Wind turbines use wind to make electricity. There is no pollution because no fossil fuels are burnt to generate electricity.
• Solar - 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. Solar energy is an essential energy of all non-conventional sources but its usage amount is very less.
• small hydro - A hydro energy system is considered to be a renewable as well as a nonrenewable energy system. The characterization of a small hydro energy system changes but an electrical energy-producing capacity of up to 10 megawatts (MW) is generally established as the higher limit of what can be termed a small hydro energy power plant.
• tides - 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 heat - 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. Due to this, there is an increase in the use of geothermal energy. It helps in reducing global warming and does not create pollution.
• biomass - 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.
