It was another underwhelming week for the stock markets, with the broad markets and broad clean energy indices all losing ground over the five days. 

The only strongly positive clean energy sector was wind power and technology, with the EnergyBoom Wind Subindex (E•B Wind) increasing 1.35% and the First Trust Global Wind Energy ETF (FAN)  climbing 0.90%. Biggest loser was the solar power and technology sector, with the EnergyBoom Solar Subindex (E•B Solar) falling 7.34% and the Guggenheim Solar ETF (TAN) dropping 6.27%.

The broad stock market indices all had lacklustre weeks, apparently bothered by ongoing worries about the Greek economy and a meeting of Euro-zone finance ministers scheduled for Monday. Nevertheless, the broader markets managed to outperform the clean energy and energy efficiency indices this week, with the biggest exception being the EnergyBoom Biofuel Subindex (E•B Biofuel) which ended the week up 2.48%.
