In this edition of MarketFoolery, Motley Fool analysts answer a question from a reader regarding one alternative-energy stock. 

While the alternative-energy space has enormous potential, it also carries huge risk. It's often very difficult to get alternative-energy sources adopted by the general public. To that end, the gang recommends steering clear of the company in question, because it's a penny stock and by nature carries more volatility and risk than we suggest investors take on. Instead, they recommend two specific alternatives: Clean Energy Fuels and General Electric.

Check out our premium research reports on both companies. They're written by our top analysts and come with ongoing updates throughout the year about all the news as it relates to your investments.
