What energy source is used in power stations that produces carbon dioxide and water?

Fossil fuels, such as coal, natural gas, and oil, are the primary energy sources used in power stations that produce carbon dioxide and water as byproducts. When these fuels are burned to generate electricity, they undergo combustion, releasing carbon dioxide (CO2) into the atmosphere and water vapor (H2O) as a result of the chemical reaction. This process contributes to greenhouse gas emissions and climate change.
