The 3rd hard the sources of energy is changed greatly
From;    Author:Stand originally
Global the sources of energy is used had experienced great transition twice, from burn straw to arrive burn coal, from burn coal to arrive scoriaceous oil, natural gas, now is great transition of the sources of energy the 3rd, should arrive from scoriaceous oil, natural gas new energy resources, but the system of the sources of energy that can last of second birth the sources of energy, this is the great transition of the hardest the sources of energy on human history.

The sources of energy that the mankind uses the earliest is firewood bavin, experienced time of more than 10000 years probably. About-face of first time the sources of energy is from firewood bavin turns to coal, if use coke puddling to begin from 1709, to 87% what held construction of world commodity the sources of energy 1920, around experienced 200 one's remaining years. The 2nd times great transition of the sources of energy turns to oil, natural gas from coal, if be in the United States to hit a wildcat to begin from 1858, to 50% what oil, natural gas formed in world commodity the sources of energy 1959, exceed coal first and occupy the first, around experienced 100 years. Is the 3rd times the sources of energy changed greatly from why to calculate case? Arrive when to can resemble coal, oil, natural gas in that way, take world commodity the sources of energy 87% or 50% ? Be being returned to now is an unknown.

From before in light of great transition of two the sources of energy, can see the contrail that the sources of energy changes greatly, also can estimate the arduous sex that the sources of energy changes greatly at the same time.

1, transition of the sources of energy is relatively slow. Can see from the analysis above first time the sources of energy changed around to experience 200 one's remaining years greatly, the 2nd times great transition of the sources of energy makes oil, natural gas is in the proportion in commodity the sources of energy is achieved 50% , used 100 years, look the 2nd times great transition of the sources of energy reachs the peak of 87% impossibly in that way like coal. The 3rd times great transition of the sources of energy wants to return very difficult final conclusion now with how many time. " encyclopedia of the sources of energy " say: Charming of Lai of  of coffin of Mao of lip of Mo of basketry billows let down with a rope a bit otter of  of grave of さ of  of Ju of Ju Huan of  of  of sole of  of  of in the company of the time with old?00 of  of  of Dong of flatter of heart of 4 the tenth of the twelve Earthly Branches Home Tiao. " encyclopedia of Chinese the sources of energy was published 1997, his estimation is to want 21 centuries end, namely 2100 but 50% what second birth the sources of energy holds construction of world commodity the sources of energy. Of course what we hope to change is a few faster, can reduce the greenhouse gas such as carbon dioxide discharge, but it does not decide the subjective desire at us.
