Is wind power underestimated?

Wind power is blowing into the future

According to a Reuter's article, wind power could become China's second largest source of energy in just a few decades, and in just 20 or 30 years, wind power could produce more energy for China than does nuclear power.

"China has the potential to install up to 100 gigawatts of wind power, equivalent to nearly one fifth of its total current generating capacity," said Wang Weicheng, an energy professor at Beijing's prestigious Tsinghua University.

Another article notes that the world's wind energy capacity is going to triple by 2014 (more).

That's a lot of energy from a source that barely receives any attention. Why is wind power so underestimated?
