"Renewable fuels and clean energy, a sector beaten down hard since last fall, are now primed for a major comeback," says Eric Roseman, editor of The Commodity Trend Alert. Here's his top ETF play on the sector.

"With every passing day the price of crude oil rises, the secular trend to alternative energy becomes even more powerful. Consumers, companies and governments are now sick and tired of soaring energy prices.

"The long-term solution is to obviously reduce our dependence on oil and increase our consumption of renewable fuels like wind, solar, and nuclear energy.

"The bull market in alternative energy began in 2005 when a host of companies in this thriving sector went public, supported by government subsidies, especially in Germany and Spain. Interestingly, Germany and Spain have just reduced solar energy subsidies this spring.

"In my view, those subsidy cuts don't matter at this stage. When companies in the solar sector are making money, why should governments continue subsidizing them?
