  • The Great Paradox of China: Green Energy and Black Skies by Christina Larson: Yale Environment 360 on 2009-10-31
    • The experience of daily life in Beijing hardly gives the impression that the last year has been a watershed for the environment in China.
    • These two targets represent some of the most ambitious green goals in the world, and are expected to make China — in just over a decade — the world’s largest producer and consumer of alternative energy.

  • Safety Concerns Don't Slow China's Coal Boom : NPR on 2009-10-31
    • Actually, China has the worst coal mine safety record in the world. Only two months ago, 105 men were killed in one mine. Last year, approximately 3,800 miners were killed in accidents.
    • The Chinese government is under huge pressure to improve mine safety and to reduce pollution. But 80 percent of China's power is generated by burning coal.
  • China's Coal-Fueled Boom Has Costs : NPR on 2009-10-31
    • Seventy percent of China's energy comes from coal, the dirtiest of all fuels to produce energy. Coal is literally powering China's seemingly unstoppable rise to superpower status, but not without costs to people and the environment.
    • China will build 500 coal-fired power plants in the next decade, at the rate of almost one a week. This massive appetite for coal means equally huge greenhouse gas emissions

    • Unless China finds a way to clean up its coal plants and the thousands of factories that burn coal, pollution will soar both at home and abroad. The increase in global-warming gases from China's coal use will probably exceed that for all industrialized countries combined over the next 25 years, surpassing by five times the reduction in such emissions that the Kyoto Protocol seeks.
    • The sulfur pollution is so pervasive as to have an extraordinary side effect that is helping the rest of the world, but only temporarily: It actually slows global warming. The tiny, airborne particles deflect the sun's hot rays back into space.

    • The second big decision facing China lies in how efficiently the heat from burning coal is converted into electricity. The latest big power plants in Western countries are much more efficient. Their coal-heated steam at very high temperatures and pressures can generate 20 to 50 percent more kilowatts than older Chinese power plants, even as they eject the same carbon-dioxide emissions and potentially lower sulfur emissions.
    • The third big choice involves whether to pulverize coal and then burn the powder, as is done now, or convert the coal into a gas and then burn the gas, in a process known as integrated gasification combined combustion, or I.G.C.C.

    • China must make some difficult choices. So far, the nation has been making decisions that it hopes will lessen the health-damaging impact on its own country while sustaining economic growth as cheaply as possible. But those decisions will also add to the emissions that contribute to global warming.

    • There are growing concerns about the impact of this coal boom on the environment. The Asian Development Bank says it is financing pollution control programs in Shanxi because the number of people suffering from lung cancer and other respiratory diseases in the province has soared over the past 20 years. Yet even after years of government-mandated cleanup efforts the region's factories belch black smoke.
    • China is also the world's largest emitter of mercury, which has been linked to fetal and child development problems, said Dan Jaffe, an atmospheric scientist at the University of Washington.

    • One goal is to build urban communities for 300 million people over the next two decades.
    • The difference from most wealthy countries is that China depends overwhelmingly on coal. And using coal to produce electricity and run factories generates more global-warming gases and lung-damaging pollutants than relying on oil or gas.

    • Researchers in California, Oregon and Washington noticed specks of sulfur compounds, carbon and other byproducts of coal combustion coating the silvery surfaces of their mountaintop detectors. These microscopic particles can work their way deep into the lungs, contributing to respiratory damage, heart disease and cancer.
    • Unless China finds a way to clean up its coal plants and the thousands of factories that burn coal, pollution will soar both at home and abroad.
