The Earth receives approximately 1.6 * 10^18 units of solar energy annually, which is significantly more than the total energy requirements of mankind, estimated to be 2000 times more. The equator divides the Earth into two equal parts, and the regions between the Tropic of Cancer and the Tropic of Capricorn experience a tropical climate, which is conducive for solar energy generation. India, located near the equator, is classified as a tropical country, receiving abundant sunlight throughout the year, with approximately 250 to 300 sunny days annually. A map of solar radiation reveals varying intensities of solar energy across different regions, with Rajasthan receiving the highest amount of solar radiation, measuring 6.4 kilowatt-hours per square meter daily. The northeastern states of India receive the least solar radiation, while Rajasthan continues to lead in annual solar radiation availability. Applications of solar energy include heating, cooking, and electricity generation through solar heaters, solar cookers, and photovoltaic cells, respectively. Wind Power Wind power is generated from the movement of air, which occurs due to uneven heating of the Earth's surface. The kinetic energy of moving air can be converted into useful energy forms, such as electricity, through wind turbines and wind pumps. Wind turbines are designed to harness wind energy effectively, and their height is crucial as wind speed increases with elevation. The advantages of wind power include its abundance, renewability, and pollution-free nature, making it an environmentally friendly energy source. However, wind power has disadvantages, including its intermittent availability, which may not meet energy demands consistently. Wind farms, areas where wind energy is harnessed, are primarily located in Tamil Nadu, Andhra Pradesh, Karnataka, Gujarat, Kerala, Maharashtra, and Lakshadweep. Biogas Biogas is a gaseous fuel produced from the fermentation of organic matter, such as agricultural waste, animal waste, and human waste. The fermentation process involves microorganisms breaking down organic materials in the absence of oxygen, resulting in gas release. Biogas plants are established to produce biogas, and they can be set up by municipalities, cooperatives, or individuals. Biogas has several advantages, including improving the quality of manure, preventing deforestation, reducing air pollution, and providing a clean fuel option with higher thermal efficiency compared to traditional fuels. Applications of biogas include its use as a fuel for heating and cooking, as well as for generating electricity through gas engines. Tidal Energy Tidal energy is derived from the gravitational forces exerted by the moon and the sun, which create tides in the oceans. The energy from tides can be converted into electricity using turbines placed in tidal streams or estuaries. When high tides occur, water flows into a dam, and when the tide recedes, the stored water is released back, driving turbines to generate electricity. Regions in India with potential for tidal energy generation include the Gulf of Khambhat and the Gulf of Kutch in Gujarat, the Sundarbans in West Bengal, and the western coast of India. Geothermal Energy Geothermal energy is derived from the heat stored within the Earth, which increases with depth. As underground water absorbs heat, it can turn into steam, which is then used to drive turbines for electricity generation. Geothermal power plants utilize this steam to produce electricity, and the used steam is cooled and converted back into water for reinjection into the Earth. In India, geothermal energy is harnessed through established plants in Parvati Valley near Manikaran in Himachal Pradesh and in Puga Valley in Ladakh. 🔔 SUBSCRIBE and GET it FREE:    / @free-educations
