Can China Catch a Cool Breeze?

An article in The Nation takes a look at the future of wind power in China:

The global economic crisis has hit China hard. The country’s exports and Gross Domestic Product growth have dropped dramatically; over the past year tens of thousands of factories have closed, and an estimated 20 million workers have lost their jobs. Social unrest is growing, and many fear it could spin out of control. In the face of that, China must boost its internal investment and consumption. In other words, China, which exports much of its savings, must absorb more of the surplus it generates–it must stimulate its own economy. The Chinese government’s $585 billion stimulus package, announced in November and dedicated mostly to infrastructure, is an attempt to do just that. A second, equally massive intervention may be on the way soon.

At the same time, China faces an array of interconnected environmental crises. Foremost among them is air pollution caused by heavy use of coal. For the unconditioned foreigner (such as your reporter) who shows up in the leaden, acrid filth of an overcast day in Beijing or Chonqing, the physical effects can be immediate headaches, nausea and disorientation. Even much of rural China is choked by this poisonous, soot-laden air. Coal pollution is estimated to cost China at least 7 percent of its GDP annually in lost productivity. A recent Pew survey in China found that more than 70 percent of respondents said air quality was a serious problem; water quality is seen as equally dire.

Desertification and severe water shortages are beginning and will get worse as Himalayan glaciers disappear and rainfall is disrupted by climate change. Later this century, a rise in sea level is predicted to inundate many coastal cities and much of the country’s industrial base.

The mountainside sprawl, repeated in variations all over China, might work to stimulate the economy. But environmentally it will bring disaster. On the other hand, retooling the energy system–à la the windmills–could solve both problems by radically reducing the country’s carbon emissions while stimulating the economy.
