Fossil fuels are energy sources that come from the reamins of plants and animals. These remains are millions of years old.
fossil fuels can be used as an energy source to power all vehicles and most machinery
Coal is a source of energy but i dontknow about all of them.
Rocket fuels are used. It contains chemical energy
The most common source of energy used to produce electricity is fossil fuels, such as coal, natural gas, and oil. These fuels are burned to generate heat, which is then used to produce steam that drives turbines to generate electricity.
Because it cant be used again once it's first used
Fossil fuels are exhaustible. Electric energy is an alternative.
Fossil fuels.
Yes, the sun is the original source of energy for solar fuels. Solar fuels, such as hydrogen or biofuels, are produced using sunlight through processes like photosynthesis or artificial photosynthesis, where energy from sunlight is used to convert water and carbon dioxide into fuel.
Any energy source that is an alternative to fossil fuels. They are used to avoid the damages that fossil fuels do to our environment such as: Carbon dioxide emissions which leads to global warming and acid rain.
Coal is a material that formed from the decay of ancient organisms and is used today as a source of energy.
they can be used instead of fossil fuels like bio diesel which can be used in automobiles.
The most widely used energy source today is fossil fuels, particularly oil, coal, and natural gas. These fuels are responsible for a significant portion of global energy consumption, but there is a growing shift towards renewable energy sources like solar, wind, and hydro power.
