billion market, while the U.S. trails at 6 percent. Chinese manufacturers also dominate the market in eco-products: from electric bikes and solar hot water heaters to mass-produced electric cars. In a few years, China's also expected to become the top exporter of wind turbines, and a major user of them too. There are more than 12,000 wind turbines stretching across China. China's turbines generate just over 12,000 megawatts of energy, vs. more than 25,000 megawatts in America. But it's catching up fast: its wind capacity has doubled annually since 2002. Green Energy is the 21st Century All this activity is putting food on the table for workers like 37-year-old Wang Meiqiu. Her hometown, the city of Baoding in China's central Hebei province, was once a decaying factory zone. But, with major state backing, it's being reborn into an unlikely eco-hub boasting 29,000 new jobs, including one for Wang. "This is solving our unemployment problem," she said. The U.S. faces a huge disadvantage in situations like this. The average factory worker in China costs a company 81 cents an hour to employ, compared to an average of $29.98 an hour for a worker in the United States. Even after taking China's low cost of living into account, it's a difference America can't match. The disparity brings down China's prices. Chinese wind turbines, for instance, are ]
