Alternative energy resources includes ethanol wind power and solar power. All of these produce fewer green house gases than oil or coal and when more developed could help the nations to be less dependent on other countries that produce more oil.
For then most part however alternative energy sources have not been developed to the point where they could produce energy as cheaply or efficiently as can be done with oil natural gas or coal.
World energy consumption:
Every minute about 272400 MWh energy is being used in the world. It means we use about 392,267520 MWh energy a day out of which about 87% from non renewable resources and 13% from renewable resources.
In 2008 energy supply by power source was oil 33.5% coal 26.8% gas 20.8% fossil 81% other hydro part solar wind geothermal power biofuels etc. 12.9% and nuclear 5.8%. Oil was the most popular energy fuel. Oil and coal combined represented over 60% of the world energy supply in 2008.
