On a recent Mad Money episode, Cramer said that environmental “green plays” have been solid plays because of high oil prices. "We correctly anticipated that oil would be up huge, $125 is still our price target," he said. "It's high oil prices that have driven up everything related to clean energy. This is the trend behind the trend. I don't think it's going away." Cramer has backed a number of these “green plays” and First Solar has been the biggest winner, up 350%+ over the last year. "I have been the strongest backer of this stock out there, and I remain so," he said. "It will be the standard of this country no matter which presidential candidate wins, as it already is the standard in Germany." He is still a strong believer in FSLR as he believes its ability to produce panels in a cost effective manner (without using silicon) will allow it to continue to hit its numbers. "I think this is to solar what Intel (INTC) was to chips," he added.

Cramer recently touted El Paso Energy (EP), a stock which he owns for his charitable trust, Action Alerts PLUS, as his new natural gas play. El Paso owns and operates the largest natural gas pipeline in the U.S. and also operates in Brazil, Asia, Central America, and South America. Cramer feels the company’s true value has been lost on the investment community due to the different operating segments of the business: exploration and production on one hand and pipeline on the other. There has been rumors of a break-up of these 2 segments which could unlock serious value in the share price. Cramer doesn’t believe this is necessary but does feel it is a big reason the stock has grossly underperformed by nearly 10x in its sector year to date. He pointed out that both business units are stronger than ever and investors need to take note now. The company certainly has as witnessed by the heavy insider buying of late. Cramer ended by saying flatly: "El Paso is the cheapest natural gas play out there.”
