A limited supply of silicon used to make solar panels and a deluge of homeowners rushing to install solar power before state rebates are reduced have made it difficult for installation companies to meet demand.
A mirror alignment measurement device, invented by Rich Diver, a researcher at Sandia National Laboratories, may soon make one of the most popular solar collector systems—parabolic troughs— more affordable and energy efficient.
University of Utah physicists have developed small devices that turn heat into sound and then into electricity. The technology holds promise for changing waste heat into electricity, harnessing solar energy and cooling computers and radars.
National green certification programs now exist to recognize and encourage green building. They share the same goal—to promote green construction and create buildings and homes that use less energy, water and other natural resources; improve indoor air quality; and create less waste. The U.S.
According to the San Francisco Chronicle, Stanford University’s Global Climate and Energy Project (GCEP), formed in 2002, currently has 42 initiatives underway, involving 59 principal investigators at 10 institutions around the globe.
There seems to be two conflicting certainties about the photovoltaic (PV) or solar module installation market: It is a rapidly expanding and lucrative opportunity, and curiously, not that many electrical contractors are aware of it or have chosen to explore its potential.
"Sustainable development involves … meeting the needs of the present without compromising the ability of future generations to meet their own needs,” was said at the Earth Summit in Rio de Janeiro in 1992, and subsequently adopted by the President’s Council on Sustainable Development.
A Study of the Potential for geothermal energy within the United States, led by the Massachusetts Institute of Technology (MIT), has found mining the heat in the Earth’s hard rock crust could supply a substantial portion of electricity to the United States.
The Integration of photovoltaics (PV) into building systems represents a growth market for the electrical contracting firm. PV combined into exterior building elements such as the building’s roof and exterior walls is typically referred to as building-
