    Energy is extracted from fossil fuels through combustion, a process where these fuels, such as coal, oil, and natural gas, are burned to release heat. This heat is used to produce steam, which drives turbines connected to generators, generating electricity. In transportation, fossil fuels power internal combustion engines, converting fuel into kinetic energy to move vehicles. This extraction process releases carbon dioxide and other pollutants, contributing to environmental concerns like climate change.
