To limit risks when investing in alternative energy, Keith Fitz-Gerald notes, "We look for companies that have an actionable business model, a strong financial position, and an actual revenue stream."

The contributing editor to Monday Morning, a daily global news service, says, "One company that meets all these objectives is U.S. Geothermal (NASDAQ: UGTH). The firm has been in start-up mode for a few years now, but it's now set for the big time.

"Since I started following this tiny dynamo, the stock price has risen 278%. Even so, we're just starting to experience this company's true power -- pun absolutely intended.

"As its name implies, U.S. Geothermal is a renewable energy company focused on the production of electricity using geothermal energy. To break this down very quickly, geothermal power utilizes naturally heated underground water springs to turn turbines above ground by injecting water into the ground and pulling out steam.

"The company is sitting on two geothermal sites. There's the Raft River site (8.2 square miles), which is about 200 miles south of Boise, Idaho (formerly a geothermal test site for the Carter administration), and the Neal Hot Springs site in eastern Oregon (8.5 square miles).
