What is the primary purpose of thermal power plants?

The primary purpose of thermal power plants is to generate electricity using thermal energy. These plants convert the heat energy released from the combustion of fuels, such as coal, natural gas, or oil, into electrical energy. The process typically involves heating water to produce steam, which then drives turbines connected to generators, resulting in the production of electricity.

Thermal power plants are one of the most common sources of electricity worldwide, primarily due to their ability to produce large amounts of power and their established technology. They play a critical role in meeting the energy demands of industries and residential areas.

The other options do not align with the primary function of thermal power plants. Harnessing solar energy relates specifically to solar power plants, while utilizing wind currents pertains to wind energy facilities. Conserving energy is a broader goal that encompasses various technologies and strategies rather than the specific operation of thermal power plants.
