If you operate or manage a government building, "green" power may be in your future. New rules are calling for some of your electricity to be generated by technologies that, only a few years ago, were regarded only as fringe contributors to power grids.
Amidst the fallout and confusion rendered by electric deregulation, one bright spot has been a resurgence of interest in renewable power from such sources as hydro, wind, geothermal, biomass, and solar photovoltaics (PV). Renewables are generally credited with generating power that results in little, if any, of the usual pollutants and a major reduction in the carbon dioxide that is believed to contribute to global warming.
