China too much likes the coal

How to struggle against climatic warming if each does not put his in it? While China dethroned last year the United States of their position of first transmitter of gas with greenhouse effect, a report published in Beijing this week underlines that Chinese rejections could double before 2020.
Every week, have underlined recently three American researchers of the Massachusetts Institute of Technology (SHOULD) (PUT), China links to network between three and four edges of five hundred megawatts, principally fed by some coal. This last would represent 82 % of greenhouse gas emissions China, against 42 % at worldwide level and 36 % in the United States.
According to Steinfeld, to Ballast Cunningham and, of SHOULD PUT, who reviewed 85 Chinese installations (that is 9 % totals), the new power stations with coal are more and more often equipped with technologies to struggle against pollution, notably oxides of sulphur, reputed to cause acid rains and respiratory diseases. Besides, the producers are encouraged by authorities to buy in fuel with content of sulphur reduced, and big units — more competitive are preferred to the babies. But no more than elsewhere, power stations with coal Chinese can avoid programme of carbon dioxide, for lack of efficient and profitable technology of capture and of sequestration of these gases.
The tremendous often upper, Chinese economic growth in 10 % a year, causes a thirst for energy and for electricity. The country establishes wind as long as it not much. With 6000 installed MW, the country heaved itself on the fifth worldwide rank. Production capacity could achieve to be multiplied by fifteen before 2020 and China will soon be the worldwide leader in the field. But it is not so much enough the country needs energy. Even the nuclear technology, however with the wind in poop, can nothing there. Alone the coal can answer rather quickly and in an efficient way request.
A doubling of greenhouse gas emissions before 2020, as lets it hear the study published in Chinese, would be paradoxically a good news. Because these last years, economy doubled its activity every five years, and almost doubled its power consumption at the same time. A doubling between 2008 and 2020 would be therefore the sign of a slowing down of the mad growth which knows the country, the double of a net progress in energy efficiency (1).
But in the meantime negotiations on after - from kyoto will not be simple. The European Union, which bets on a fall of 80 % of its own greenhouse gas emissions before 2050 claims a fall in Beijing from 15 % to 30 %. Why so not much, while China is well ahead at the head of the heaters of planet? Because other heavyweights of greenhouse effect (the United States, Russia, Europe, Japan, etc.) issue for a long time. Besides, China always shows programmes per head very lower to that of Western countries. You should not forget either than a good part of its programmes is linked to our appetite for products made in Bargain-hunted. This week, they besides confirmed the weight growing by a powerful gas with greenhouse effect until then neglected in balance sheets, trifluorure of nitrogen. A very used gas, notably in China, to fabricate the flat screens about which Occident (2) is crazy.
In when a balance sheet of the programmes of each, taking into account importation and export?

Isn't the time against us?
USA have echoue, of meme whom their partners europeens. The first would have to ratify kyoto and to assure its monitoring with seconds, unfortunately, nothing has ete made. And however we suffer every day the consequences of our passivite when has the struggle against the climatic rechauffement.
I share your opinion Sofia, we indeed do not go to arreter the waves of the rechauffement tomorrow, because what we re-smell at present is others than the resultats of acts poses anterieurement. Therefore, we still do not have recu of feedback of recents acts, rest has patients etre. Of meme whom to act now would not have of effect immediat.N' empeche that we must struggle for not amplifying the saving actions which our children will have to deployer, otherwise them prefereraient of step naitre, seen the heritage to be weighing whom they will have of us.
But the men fit to the worst as all kinds. Find t-on no bacteria and other living beings in extreme conditions.
As for going to make poussr tomatoes over March, they would have to want CH4, just as the human being would have to fit to a chimiostnthèse.
In view of the fact that they are not enough representative to change before …
