primary sources of energy consisted of petroleum 36.0%‚ coal 27.4%‚ and natural gas 23.0%‚ amounting to an 86.4% share for fossil fuels in primary energy consumption in the world. (“U.S. EIA International Energy Statistics") Fossil fuels are of great importance because they can be burned (oxidized to carbon dioxide and water)‚ producing significant amounts of energy per unit weight. The use of coal as a fuel predates recorded history. Coal was used to run furnaces for the melting of metal ore

Because they cannot be renewed fast enough to keep pace with consumption‚ they are considered non-renewable and are the most commonly used type’s energy. Fossil fuels were formed over millions of years when decomposed plant and animal matter were buried by layers and layers of the earths crust and then it was transformed into carbon-rich material that is used as fuel.

Electric cars how they will make the world worse. “ Electric cars are coal powered cars. Their carbon emissions can be worse than gasoline powered cars.” Vinod Khosla. Electric cars are supposed to be the next thing for the world because people they don’t produce coal because they don’t need gas. Electric cars are bad because of refueling time ‚ cost ‚and how it affects the environment and people. The electric car takes to long to charge. The electric car takes about 1 to 8 hours to charge
