Non-renewable energy is the type of energy once used, it can not recover in a short time. These energies have a very high capacity to generate electricity, fuel and thrust and are not difficult to exploit. With mining and processing so popular all over the world, most people rely on this type of energy, whether to provide electricity for domestic use, propulsion for travel or fuel for cooking. Eat, this is the kind of energy that we cannot lack. More than 85% of the energy used in the world comes from non-renewable sources. Non-renewable energy is divided into two types, fossil energy and nuclear power. The three main types of fossil energy are oil, coal and natural gas.
