China climate pledge would require 50,000 solar farms.

Bloomberg: China, which does nothing in small doses, will need about 1,000 nuclear reactors, 500,000 wind turbines or 50,000 solar farms as it takes up the fight against climate change.”
“Chinese President Xi Jinping agreement last week with President Barack Obama requires a radical environmental and economic makeover. Xi’s commitment to cap carbon emissions by 2030 and turn to renewable sources for 20 percent of the country’s energy comes with a price tag of $2 trillion.
The pledge would require China to produce either 67 times more nuclear energy than the country is forecast to have at the end of 2014, 30 times more solar or nine times more wind power.
That almost equals the non-fossil fuel energy of the entire U.S. generating capacity today. China’s program holds the potential of producing vast riches for nuclear, solar and wind companies that get in on the action.
China is in the midst of a period of transition, and that calls for a revolution in energy production and consumption, which will to a large extent depend on new energy,” Liang Zhipeng, deputy director of the new energy and renewable energy department under the National Energy Administration, said at a conference in Wuxi outside of Shanghai this month. “Our environment is facing pressure and we must develop clean energy.”
By last year, China had already become the world’s largest producer of wind and solar power. Now, with an emerging middle class increasingly outspoken about living in sooty cities reminiscent of Europe’s industrial revolution, China is looking at radical changes in how its economy operates.
….Meeting the challenge is anything but assured. China has already run into difficulty managing its renewables. About 11 percent of wind capacity sat unused last year because of grid constraints, with the rate rising to more than 20 percent in the northern provinces of Jilin and Gansu, according to the China Renewable Energy Engineering Institute.
With its huge population, China is a country accustomed to eye-popping goals. Some have worked, such as the rapid growth and poverty reduction from the market reforms of the past two decades. Others, though, have exposed central planning run amok, such as Mao Zedong’s Great Leap Forward in the 1950s to collectivization and industrialization.
Xi sees no alternative to going big. “Letting children live in a good ecological environment is a very important part of the Chinese dream,” he said last week as he welcomed Asian leaders to a summit in Beijing. His words aren’t just lip service — pressure is building.
Protests over pollution at least three times this summer turned violent in Chinese cities. In Hangzhou, in the eastern part of the country, rioters overturned cars and set fire to police vehicles in May because of plans to build a waste incinerator near a residential neighborhood.
In the weeks leading up to last week’s APEC summit, China closed factories and limited traffic in Beijing so the air wouldn’t be offensive to visiting dignitaries. In the capital, 141 enterprises were asked to cut production from Nov. 3 to Nov. 11, according to the Municipal Environmental Protection Bureau. Xinhua News Agency said limits were placed on 3,900 plants in Hebei province and 1,953 firms in Tianjin city.
A government previously focused on growth at all costs has suddenly become sensitive to its environmental challenges, activists say.
….The targets Xi announced alongside Obama have been hailed as a boost for negotiations at a United Nations conference beginning Dec. 1 in LimaPeru. Envoys from more than 190 nations are seeking to craft a global pact that world leaders will sign next year in Paris.
The U.S. part of the deal includes a push to cut greenhouse gas emissions to 26 to 28 percent below 2005 levels by 2025. The current U.S. target is to reach a level of 17 percent below 2005 emissions by 2020. The Obama administration will likely have to achieve these cuts largely through regulatory methods.
For China to succeed, it will have to install the clean energy equivalent of Spain’s entire generating capacity each year until 2030, according to Bloomberg New Energy Finance data. It has achieved that only once — last year.”
