Visit the
America's Next Top Energy Innovator Challenge website to cast your vote by "liking" the companies that you think could make the greatest positive impact to the country's economic and energy future. In addition to the public votes, an expert panel from the U.S. Department of Energy (DOE) will weigh in their votes. The top three companies will receive a free registration to the
2012 ARPA-E Energy Innovation Summit and a chance to present their ideas at the technology showcase. According to DOE, voting closes at 8:59 a.m. (EST) on Monday, Feb. 6.
