Geothermal Energy Concepts and Applications

This video by Mr. V reviews geothermal energy, explaining how it is derived from the Earth's heat. The process involves injecting water into the Earth's interior, where heat and pressure convert it into steam, which then powers turbines and generators to produce electricity. The video outlines the cyclical nature of this process and discusses its applications both on a large scale and in homes. However, it also highlights challenges such as high costs, limited accessibility, and potential pollution issues like hydrogen sulfide release.
