China busca reducir sus emisiones mediante la reducción de carbón

Aires nuevos en China fruto de la polución tan atroz que llega a inundar a ese país. Parece que la apuesta es más definitiva en un país que se llega a producir electricidad hasta el 80 % a base de carbón. De allí su apuesta por las renovables así como el mayor uso de gas natural. El porcentaje de uso de gas natural en China es bajísimo pero se quiere doblar hasta alcanzar el 8 %. Así mismo se quiere aumentar la proporción de eólica, solar hidroeléctrica y nuclear hasta llegar al 11 % desde niveles actuales de un 8 %. La apuesta por la nuclear en China llega hasta 40 gigawatios antes de 2015, así como 120 gigawatios en hidroeléctica. Consecuencia de ello será la reducción de gases de efecto invernadero en un 17 % en el plazo de 5 años.

China Congress Pushes Gas, Renewable Energy Plans: Chart of Day

March 11 (Bloomberg) -- China, the world's biggest polluter, said it would accelerate its use of renewable energy and cleaner-burning fuels including natural gas over the next five years to cut pollution and reduce reliance on coal, which generates about 80 percent of the nation's electricity.

OF THE DAY shows China aims to double gas's share of energy consumption to 8 percent by 2015 while boosting the combined proportion of wind, solar, hydro and nuclear to 11 percent from 8 percent, according to National Energy Administration data. China plans to start building 40 gigawatts of atomic reactors by 2015, more than three times of last year's capacity, documents released at the National People's Congress this week show. The country will also begin construction of 120 gigawatts of hydropower by then.

"Hydro, wind, nuclear and gas will continue to grow at double-digit rates relative to fossil fuels, which will decline as a percentage of the energy mix," Neil Beveridge, a Hong Kong-based analyst at Sanford C. Bernstein & Co., said in a note.

China won't "blindly" pursue economic growth that's unsustainable, Premier Wen Jiabao said last month, noting that the world's largest coal user would slash carbon-dioxide emissions by as much as 17 percent within five years. Russia, Turkmenistan and Australia are offering to supply more gas.

Turkmenistan plans to boost pipeline shipments to China by 50 percent, even as a supply deal with Russia is delayed over pricing issues, according to OAO Gazprom, the world's largest gas producer. Australia was China's biggest source of liquefied natural gas last year, with Chinese importers paying an average $191 a metric ton for Australian term-contracts compared with an average $323 for all imports, customs data show.

The share of oil in China's energy mix may remain at 2010 levels as the country depends less on fossil fuels while getting increased crude supplies from overseas fields that state- controlled companies including PetroChina Co. and China Petroleum & Chemical Corp. have stakes in. Last year, Chinese companies bid for a record $39.6 billion of energy assets abroad to enlarge reserves, data compiled by Bloomberg show.
