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.
According to the San Jose Mercury News, more homeowners and homebuilders are considering solar power as the government provides more incentives and concerns regarding climate change and energy prices increase.
In April 23-26, 2007, the inaugural GridWeek event took place in the Ronald Reagan Building in Washington, DC. The purpose was to raise awareness and generate support for advancing and modernizing the grid and bring attention to an impending problem.
Jacobs Field, home of the Cleveland Indians, currently is placing 50 photovoltaic panels on the upper concourse, which will generate “a modest amount of power,” according to Jim Folk, vice president of ballpark operations. The array will be 86 feet long and 15 feet high.
Funded by The Engineering and Physical Sciences Research Council (EPSRC), the University of Manchester and Imperial College London plan to investigate a number of new solar cell designs over the next three-and-a-half years, in an attempt to produce a more efficient solar power system.
In April, the world’s third-largest solar thermal power plant began generating power for Las Vegas residents in the Nevada desert. Acciona Solar Power of Spain owns the Nevada Solar One plant, located in Boulder City.
