The type of energy derived from fossil fuels includes thermal energy, which is converted into electricity and used for heating. Fossil fuels—such as coal, oil, and natural gas—contain hydrocarbons that release energy when burned. This energy is harnessed in power plants, vehicles, and industrial processes, contributing significantly to global energy consumption. However, the reliance on fossil fuels is associated with environmental challenges, including air pollution and greenhouse gas emissions, which contribute to climate change. As a result, there is a global push to transition toward renewable energy sources like solar, wind, and hydroelectric power to create a more sustainable energy system.
