EnerPath is a company that works with large corporations and small businesses to implement energy efficiency. Though it has been doing so for 20 years, recent government "green" subsidies has enabled it to make systems with higher reliability for large-scale businesses. It doesn't sell the equipment for energy consumption like air conditioning and lighting systems, but instead creates software to manage these systems. Its software EnerWorks allows all energy consumption to be reported to one mainframe for quanitifiable data.
