The United States is making the greatest push in its history to use renewable energy. However, thus far, one of the biggest obstacles for implementing renewables has been the United States’ exorbitant energy demand, which accounts for 26 percent of the world’s energy consumption.
On the May 14, 2012, Washington, D.C., Mayor Vincent Gray joined officials from the District Departments of Transportation (DDOT) and Environment (DDOE) to replace the last of approximately 1,360 alleyway lights with new energy-efficient light-emitting diode (LED) lamps.
Like all renewables, photovoltaics (PVs) are in a constant state of innovation. Researchers are forever striving for breakthroughs in materials and productivity to help them lower costs and chip away at the historical advantage enjoyed by fossil fuels in mainstream energy markets.
After engineer David Kaneda’s firm moved into its own self-designed zero-energy building, an analysis of the zero-energy claim revealed that their photocopiers, printers, clock radios and coffee pots were threatening efforts to make the building self-sustaining.
Energy efficiency is often the ugly stepsister in alternative-energy conversations because quantifying its potential effect is difficult; how do we determine the real value of all those avoided kilowatt-hours?
The second step in the energy services project delivery process is normally thought to be an energy audit; it is the cornerstone of energy service. While it is a key component, an energy audit is only one form of assessment.
By Oct. 18, 2013, all states in the United States must put in place a commercial building energy code at least as stringent as the ASHRAE/IES 90.1 2010 energy standard, according to a Department of Energy (DOE) ruling on Oct. 19, 2011.
The last energy services column (January 2012) introduced an 11-step energy services project delivery process. Electrical contractors can follow the process systematically, thereby developing a comprehensive program to help their customers identify and achieve energy and sustainability goals.
The U.S. Department of Defense (DOD) is the nation’s biggest energy customer, and it wants to cut its bills. The DOD’s armed services all have initiatives underway to reduce energy use and increase adoption of renewable technologies, in both overseas operations and at stateside bases.
Whether California’s nickname refers to its plentiful sunshine or the pursuit of riches, the Golden State provided an appropriate venue for the National Electrical Contractors Association’s (NECA) first Energy Forum. On Saturday, Oct.
Employing daylight to reduce electricity can be an attractive energy opportunity for building owners and operators, with lighting accounting for nearly 40 percent of all energy consumed in modern buildings.
The U.S. Green Building Council (USGBC) announced that the Green Building Certification Institute (GBCI) has certified the 10,000th LEED commercial project. Created in 2000, the LEED green building program has become a mainstay in sustainable building certification.
