The natural resource most commonly used for producing energy is fossil fuels, which include coal, oil, and natural gas. These resources are formed from ancient organic matter and are extracted from the Earth's crust. Fossil fuels are burned to generate electricity, power vehicles, and provide heat for homes and industries. Despite their widespread use and efficiency, fossil fuels are significant contributors to greenhouse gas emissions and climate change. As a response to environmental concerns, there is a growing push toward alternative energy sources like solar, wind, and hydroelectric power to create a more sustainable energy future.
