Our nation's energy infrastructure is strained to capacity. The situation leads to brownouts, which resulted in a productivity loss of $80 billion last year. Most importantly, electricity demand is climbing and the cost of building out new infrastructure is extremely expensive. America needs to be more efficient; it needs to create a smarter grid. For those reasons, Motley Fool Stock Advisor analyst Matthew Argersinger thinks it's time investors looked to EnerNOC. Click on the video below to hear his thoughts on the company, then read on below:

EnerNOC frees up electricity demand through its network of customer sites, where EnerNOC monitors electricity usage and at peak times can actually ratchet down power. The agreement is win-win; both EnerNOC and customers get paid, and customers end up saving power. Customer growth has been enormous, swelling from around 2,200 sites at the end of 2007 to more than 7,000 today. There are some pretty hungry power users in that bunch also. Pfizer (NYSE: PFE), General Electric (NYSE: GE), and supermarket chain SUPERVALU (NYSE: SVU) have all adopted EnerNOC's solution.

While there's stiff competition from larger firms like Honeywell (NYSE: HON) and Johnson Controls (NYSE: JCI) as well as smaller players like Comverge (NYSE: COMV), Argersinger believes EnerNOC's unique position will make it a leader in this vast market opportunity during the coming years.
