Power plants are facilities that generate electricity by converting various forms of energy into electrical energy. This process typically involves the use of steam, gas, water, or combustion of fossil fuels to drive turbines and generate electricity. Power plants can be classified based on the primary source of energy they use, such as coal, natural gas, nuclear, hydroelectric, wind, solar, or geothermal power. The efficiency, environmental impact, and cost-effectiveness of power plants vary depending on their specific technology and fuel source. Researchers in this field focus on improving the efficiency, sustainability, and reliability of power generation, as well as developing new technologies to reduce emissions and environmental impact.
