Fossil Fuels, Non- Renewable Source of Energy

Fossil fuels are a non- renewable source of energy. Fossil fuels include objects like coal, natural gas and oil. Fossil fuels are made of plants and animals that lived more that 300 million years ago and are found in deposits beneath the earth. Over 90% of our energy is made from fossil fuels. Out of many major countries the USA is the one which consumes most of the fossil fuels. Byproducts that form from the burning of fossil fuels are very dangerous to humans and other animals       **//** . **
