Sciences and Futur The Challenge of
Coal is to take up for save the planet of one warming above of 2 degree in 2050 because the global demand has doubled in 35 years and, with the actual logic,
according the AIE (Agency International of Energy) his consumption could inscrease of 73 per
cent in 2030. This source of fossil
Energy stay essential in the world of make of the steel ( coke coal) or of
electricity (vapour coal). We estimate his reserves to 150 years of consumption. In more, his cost price is low, his easyness of transport and his distribution of all the continents continue to be attractive even if the France use to nuclear and pratically wean of coal since the closing of the last mine in Lorraine (french region), continue to think that it’s obsolete. It’s the case according to AIE, appeal to succeed to petrol ( more one hundred dollars the barrel) and to gas as the price is indexed on black gold. But, to moment where the countries try paradoxically to arrest the climate change, in 2005, the coal has emit more of CO² that the petrol and his emissions will raise of 70 per cent in 2030 ; because his strong content intrinsic to carbon and his
low efficientness of firm who burn it. And if we refine the coal for produce of liquid fuel, the global emissions to greenhouse effects rise rapidly. “ We prefer to travel to petrol and catch the CO² by the burning of coal” analyse Cedric Philibert responsible of political on reducing of climate change to the division of energy and environment efficacity of the AIE. Actualy, we know limited the impact of his gas on the environment but the industrial process will be ready in 2018. Adding, his burying durable and reliable isn’t ready too. The Austrilia, the United-States, the India and the China, also Europe are chosen the coal. According to the WWF association, in May 2007, the thirty energy station the most polluating are situed in Germany and in Great Britain. We foresee, according to AIE, for keep the energy independance (Russian gas), the building of four urge station by year during thirty years, low expensive that the nuclear. She must catch the CO² to part of 2020. The Europe foresee to produce also 20 per cent of his electricity to part of renewables energy. To United States, his scruple aren’t observed and the part of electricity produce by the coal will raise of 60 per cent in 2030, indicate Catherine Gautier of the University of California to Santa Barbara. Except to change of energy policy, the coal could supply 55 per cent of electricity to country to the same date. Bitter report, on 170 coal station, only 33 are clean. The climatologue James Hanser ring the alarm bell. They should have a take of general consiousness because the americans can react fast, the conctractors are ready to invest in the technology solutions. In spite of the signs worrying coming of Asia : The China consume more of 38 per cent of global coal and, for satisfied the city-dweller, his consumption has doubled between 2000 and 2006. However, the new stations using low of coal with a better output, but without unit of catching of CO² because she reduct the global output of 8 to 13 per cent. A black scenario is drawn until that 2050. We don’t escape until this date to pay the energy bill.
