After four hurricanes passed through Florida in 2004, leaving a tangle of downed power lines and outages, the most reliable power source proved to be solar.

A 500-kilowatt solar power system supplements 15 percent peak power to water treatment operations in northern New Jersey. A 250 kW fuel cell helps manage electricity demand and address ongoing air-quality concerns at a Southern California water reclamation plant.

Photovoltaics (PV) have a sunny future in the building industry. After a number of false starts over the past 30 plus years, PV has the potential to become a significant contributor to the U.S. energy supply in the coming decades.

The Leadership in Energy and Environmental Design (LEED) recognizes the contribution that photovoltaics (PV) make to the sustainability and efficiency of a building project through its Green Building Rating System for New Construction & Major Renovations (LEED-NC Version 2.1).

Photovoltaic (PV) installations are becoming more common in commercial and residential buildings as PV-system efficiencies increase, installed costs decrease and cost of conventional utility-supplied electric power increases.

A utility-interactive photovoltaic (PV) system is defined in Section 690.2 of the National Electrical Code (NEC) (NFPA 70-2005) as a “photovoltaic system that operates in parallel with and may deliver power to an electrical production and distribution network.” NEC Article 690 covers Solar Photovol

Advances in Photovoltaic (PV) materials and manufacturing processes are resulting in increased interest in the application of PV technology in buildings.

An energy transition with the potential to revolutionize the country's infrastructure is gaining momentum. It is not brokered through expanded power grids or traditional fossil-based economics-it is powered through fuel cells. Fuel cell development is on the upswing.

In the heart of Detroit, surrounded by erosion and boarded-up businesses, a major construction project is nearing completion.
