What type of fuel produces greenhouse effect?

Fossil fuels, such as coal, oil, and natural gas, are the primary types of fuel that produce greenhouse gases when burned. These fuels release carbon dioxide (CO2) and other greenhouse gases like methane (CH4) and nitrous oxide (N2O), which trap heat in the Earth's atmosphere. This process contributes significantly to global warming and climate change. Renewable energy sources, like solar and wind, produce little to no greenhouse gases, making them more environmentally friendly alternatives.
