Most of the world’s energy resources are being supplied by fossil fuels like coal, oil and natural gas. But the world’s dependence on fossil fuels is no good for several reasons. One is the fact that coal, oil and gas will eventually run out. No one knows exactly when, but the US Department of Energy says we have roughly 104 years of fossil fuels left, and that’s if global consumption stays the same, which it probably won’t. It’s been estimated that by the year 2020, world energy consumption will increase 50 percent. So it’s a matter of decades before the world runs out of its main source of fuel. Another problem caused by burning up 350 quadrillion BTUs of fossil fuel a year, is the creation of a substantial amount of carbon dioxide, which is contributing to global warming and the subsequent melting of the ice-caps. And of course air pollution threatens human health and that of the planet. The solution to all this is to find energy sources that are clean or green, and preferably won’t run out. Green fuel is something the whole world knows it will have to invest in sooner or later. Iran is one of the nations trying to reduce its dependence on fossil fuels.
