Each week I recap the results of the WilderHill New Energy Global Innovation Index, symbol NEX, and published by New Energy Finance Ltd. The index consists of approximately 90 stocks from 22 countries. The NEX is the tracking index for the PowerShares Global Clean Energy Portfolio ETF (PBD: 9.70 0.00 0.00%).

Last week the NEX returned to its losing ways, shedding 12.2%. The major market averages NASDAQ and S&P 500 were off 8.3% and 7.4%. AMEX Oil fell 7.1% along with falling oil prices.

The solar energy sector was the largest decliner, losing 20.1%. All components of the sector fell on the news of decreased demand for solar equipment.

Wind energy, co-largest sector along with solar, posted a modest loss of only 6%. Wind was only outperformed by power storage, which declined 4.7%. In the wind sector, Chinese turbine manufacturer Goldwind climbed 30.3% on news of the Chinese government infrastructure package.
