2010年Q2のアメリカに於ける風力発電の伸び

一昨日、２０１０年Ｑ１の風力発電の伸びは５３９メガワットの伸びに終わったと書きましたが、Ｑ２も７００メガワットの伸びで終わったようです。一昨日と同じAmerican Wind Energy Association (AWEA) の数字です。Q1とQ2の半年の合計で１,２３９メガワットですが、２００９年の１年間の伸びの１０，０００メガワット（原子力発電所１０基分）より大幅な減少となっております。
AWEAは、アメリカが風力発電に対するモーメンタムを中国やヨーロッパに持って行かれるのでは無いかと警告しています。

While this wind power deal was an attractive proposition for Exelon, the American Wind Energy Association (AWEA) noted recently that there were only 700 megawatts of wind power added in the second quarter of 2010 in the U.S., which was a 57 percent drop from the amount of wind installed in 2008 and a 71 percent drop from the amount of wind installed in 2009. The AWEA said that this is a sign that the U.S. is losing the wind power race to China and Europe, which have more defined and long term federal subsidies.
It doesn’t look like the U.S. will get any more clear long term subsidies for wind power any time soon. While the stimulus bill provided hundreds of millions in short term financing for clean power, a national renewable energy standard was dropped from a version of the energy bill in July, and the energy bill itself has stalled in Congress.
However, wind can still be economical in various parts of the country. On July 30, Google, via its subsidiary Google Energy, said it would start buying clean power from 114 MW of wind energy via a wind farm in Iowa owned by NextEra Energy Resources.

今まで、太陽光発電とかに比べてワットあたりのコストがかなり安く、風力発電装置（ブレード、タービン、等）の素材や技術とかも飛躍的に向上して来て、ここまでアメリカに於ける「再生可能エネルギー」を引っ張って来ましたが、このまま失速するのでしょうか？
