Who types of fuels give out energy when burnt?

Fuels that release energy when burned include fossil fuels such as coal, oil, and natural gas, as well as biofuels like wood and ethanol. These fuels contain hydrocarbons that, when combusted, react with oxygen to produce heat and light while releasing carbon dioxide and water. Additionally, hydrogen can also be considered a fuel; when burned, it produces energy with water as the only byproduct. Overall, these fuels play a crucial role in energy production for various applications.
