The energy source is versatile used to generate electricity and heat homes and emits the least co2 of all fossil fuels Natural gas.
Biomass is a versatile renewable energy source. It can be converted into a liquid transportation fuel equivalent to fossil fuels such as gasoline, jet fuel, and diesel fuel. Fossil fuel power plants burn coal or oil to produce heat, which is then used to generate steam that drives turbines to generate electricity.
Fossil fuels are the dirtiest and most dangerous energy sources, but nuclear energy and modern renewable sources are much safer and cleaner. Electrical energy is one of the most commonly used forms of energy in the world. It can be easily converted into other forms of energy and transported over long distances safely and efficiently. As a result, it is used in daily life more than any other energy source.
