The energy is the material foundation of national economy importance, is also the basic condition that the mankind rely for existence.Speed and person's people's livelihood of national economy development live level of exaltation all depend on to provide energy of how much.See from the history, the mankind make use of to the energy of every graveness the Tu break all chaperonage science and technology of progress, promote thus productivity consumedly development, even cause society the revolution of the mode of production.Such as 18 a life time Ji watt invention steam engine, replace manpower Xu4 Li4 by steam, in an energy of consume structure top change direction with the coal generation substitute firewood of ages, beginning capitalism Industrial Revolution.70's from 19 centuries beginning, the electric power gradually replace steam as lord want motive, thus realization capitalism industrialization.20 centuries 50's, along with cheap the petroleum, natural gas be large-scale to open hair, world energy of consume structure from regard coal as principle change direction regard petroleum as principle, as a result make west economic at 60's got into " golden age".

           The energy press it a born way and is divided into natural energy(a energy) is two major types with artificial energy(two energy).Natural energy is nature in with natural form existence has been process or conversion of energy resources, like coal, petroleum, natural gas, pit fuel, wind energy, water ability, solar energy, subterranean heat ability, ocean ability, tide ability etc.;Artificial energy then from an energy direct or indirect conversion become other category and form of energy resources, like coal gas, gasoline, kerosene, diesel, electric power, steam, hot water, hydrogen, laser...etc..Among them and already drive mankind extensive make use of and is over-weight to want the energy of function in the mankind the life and the production, call for the normal regulations energy, usually is coal, petroleum, natural gas, water ability etc. be 4 kinds.But recently drive just mankind development make use of, treat in further research development of the energy resources be called new energy, in opposition to normal regulations energy, at dissimilarity of history period and science technique level under the circumstance, new the energy have dissimilarity of contents.

     Statistics according to energy meeting in the world, the world have already explore clear can adopt coal to keep quantity to add up to 1,598,000,000,000 tons, anticipating to return can mine for 200 years.Explore clear can adopt oil deposit to add up to 121,100,000,000 tons, anticipating to return can mine for 30~40 years.Explore clear can adopt natural gas to keep quantity to add up to 119 to sign a square rice, anticipating to return can mine for 60 years.Explore clear can adopt uranium to keep quantity aggregate 2,356,000 tons(have never included a central plan nation), if the benefit use good, can again use 2400~2800 years.Whole world can development water the electricity pack machine capacity to add up to 2,260,000,000?W, the year generate electricity quantity and can reach to 9800 whs, can long-term the development make use of.
