The chart given demonstrate the percentage of energy in use all over the world and the more detail dividence of renewable energy groups. Overall, although energy can be grouped into three broad categories and by far the largest one is still fossil fuels such as petroleum, gas and coal, the next is nuclear electric power and the remain supply is renewable energy that has only consumed not much. As can be seen from the chart there are three types of fossil fuels in which petroleum takes advantage with the biggest rate at 39% as compared to the natural gas and coal (23% and 22% respectively)The second major sector of energy is nuclear electric power which is a relative newcomer in the energy business with the rate at 8% in the total energy consumption. The third power is renewable energy which are essentially inexhaustible because it is naturally replenished. All forms of renewable energy together accounted for 7% concludes 53% of biomass namely wood, straw and so on, 36% of hydroelectric and a very small proportion of solar. geothermal and wind power.
