Top 10 Power Generation Companies in India

Top 10 Power Generation Companies in India Power generation involves the process of converting various forms of energy into electrical energy for use in homes, industries, and other sectors. The primary sources of energy for power generation include fossil fuels like coal, natural gas, and oil, as well as renewable sources such as hydroelectric, solar, wind, and geothermal energy. Power generation typically begins with the fuel being combusted or converted into thermal energy, which is used to heat water and produce steam. The steam drives turbines connected to generators, where mechanical energy is converted into electrical energy through electromagnetic induction.
