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 Department of Energy (DOE) released a renewable-energy resource assessment detailing the potential to develop electric power generation at existing U.S. dams that aren’t currently equipped to produce power.
I started this series of articles after a friend asked some questions about overcurrent protection for the direct current (DC) output of photovoltaic (PV) modules, the DC output of combiner boxes, the location of disconnects for both the DC side and the alternating current (AC) side of the inverter,
Renewable power has the potential to transform our energy consumption, but like most innovations, it has a downside. One of the biggest stumbling blocks to a renewable-powered society is the intermittent nature of its generation.
At an event in Albuquerque, N.M., U.S. Department of Energy (DOE) Secretary Steven Chu announced the 20 collegiate teams selected to compete in the Solar Decathlon 2013 and unveiled the competition’s location: Orange County Great Park in Irvine, Calif.
With all the popular support and government subsidies that renewable power enjoys in the United States, it seems that it would only be a matter of time before they completely take over the nation’s energy markets.
The renewable-power industry is one of the greatest showcases of human innovation and ingenuity, drawing energy from sources that are clean, free and infinite. It also seems to possess a flair for the dramatic.
The nation’s largest hydroelectric facility is about to get an upgrade. As its 75th anniversary approaches, aging transmission lines at Washington’s Grand Coulee Dam will be removed and replaced with safer, more reliable lines.
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.
Energy projects currently underway across the United states reflect several trends—new construction in the alternative-energy sector and renovation at traditional power plants to update aging infrastructure.
Sonnhalter, a communications firm marketing to the professional tradesman in the construction, industrial and MRO markets, released a market overview for the alternative-energy industry. The overview takes a quick snapshot of the industry, its players and trends.
Many measures gauge the progress of renewables’ ongoing quest to become a mainstream source of power. Among them is the race to surpass traditional sources for share of total energy production. In this regard, renewables have made great strides.
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.
