These sources not only instigate greenhouse effects but also reduce the dependence on oil and gas. ConclusionĪs the fossil fuels are one of the most the biggest pollutants on the planet, demand for the non-conventional sources is developing. It helps in reducing global warming and does not create pollution. Due to this, there is an increase in the use of geothermal energy. This energy generally involves low running costs since it saves 80% on fossil fuels. So Geothermal wells release greenhouse gases trapped within the earth and but these emissions are much lower per energy unit than the fossil fuels. Geothermal energy is the heat energy that we get from hot rocks present in the earth’s crust. 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. In areas where the sea experiences waves and tides, we can generate electricity using tidal power. Tidal power is a form of hydropower that converts the energy of tides into electricity. Biomass is an important energy source contributing to more than 14% of the global energy supply. The residue left after the removal of biogas is a good source of manure. Biomass energy is also applicable for cooking, lighting, and generation of electricity. The chemical composition of biomass varies in different species but generally, biomass consists of 25% of lignin, 75% of carbohydrates or sugar. These substances burn to produce heat energy which then generates electricity. Biomass energyīiomass is the organic matter that originates from plants, animals, wood, sewage. One of India’s largest windmill farm is in Kanyakumari which generates 380mW of electricity. There is no pollution because no fossil fuels are burnt to generate electricity. Wind turbines use wind to make electricity. These are generally located at high altitudes. Wind farms prefer areas, where winds are stronger and constant. As the wind increases, power output increases up to the maximum output of the particular turbine. Wind energy describes the process by which wind is used to generate electricity. Solar cells also use solar power to generate electricity from the sun.Solar heaters also use solar energy to heat water instead of using gas or electricity.They are applicable widely in areas of the developing world where deforestation is an issue, and financial resources to purchase fuel are not much. A solar cooker directs the solar heat into secondary reflector inside the kitchen, which focuses the heat to the bottom of the cooking vessel.It is the most important non-conventional source of energy and it gives non-polluting environment-friendly output and is available in abundant. Solar energy is an essential energy of all non-conventional sources but its usage amount is very less. In photosynthesis, green plants absorb solar energy and convert it into chemical energy. Photosynthesis process carries out this process of conversion of solar energy. Solar energy is harnessed by converting solar energy directly into electrical energy in solar plants.
