How Parking Lots Can Beat the Heat & Gain Energy
urbanlife
by urbanlife  6-6-2008    3
 On hot, sunny days when air conditioners threaten to overload the power grid, solar power generation makes a lot of sense. Parking lots in asphalt-rich cities have great solar potential because the panels can be oriented to optimize power production during summer afternoons when electricity is most valuable. Google, for example, has installed solar canopies on its parking lots to satisfy 30 percent of its headquarters' power demand. Because the parking lots for most commercial buildings are bigger than the buildings themselves, economies of scale for large installations can further reduce the cost of the solar panels. We shouldn't wait until the next heat wave to think about getting solar power from our parking lots.

 Interesting. I like to see patterns emerging in technology trends. This one makes sense, but the fact is that there are many different types of solar panels, including solar thermal and solar hot water, that are already competitive.

Photovoltaics - How they Work
Naomi-K
by Naomi-K  5-9-2008   
 It'd be nice to see a video of this.... The photovoltaic effect was first discovered in 1839. The first photovoltaic cells were made in 1918. Since then Einstein developed photovoltaics. There was a lot of research and development during the 1960's Space Race, when satellites were powered by solar panels. The 1970's saw the beginning of residential solar use. For houses living far off the electricity grid, photovoltaics made financial sense. Prices have since fallen from $30 a watt down to $7 a watt for residential installations. Now due to technology advancing and power costs rising, the price of solar energy is still falling. The future of solar energy looks bright indeed.

The Myth Of Energy Independence
merrie
by merrie  3-18-2008   
 Where did this notion of energy "independence" come from? Energy independence is not a new idea in American politics. Richard Nixon first started talking about it in 1974. The problem is it's no more feasible today than it was then. What about cellulosic ethanol, made from switch grass or corn stubble? I cite an analysis that was done by former CIA Director John Deutsch, who's now a professor at MIT. If his estimates are correct, producing enough cellulosic ethanol to displace just half of America's daily consumption of 20 million barrels of oil would require the U.S. to plant an area approximately equal to 1.5 times the size of Texas. That's a big area. If we could get the efficiency of the photovoltaic panels high enough, solar, ultimately, has more applicability. There are a whole lot of rooftops in this country you could put them on. Researchers are having better luck at converting larger parts of the light spectrum into energy.

 Thin film photovoltaics are an interesting develpment. Fuelled by a worldwide shortage of silicon (caused by a huge growth in demand for solar energy) thin film solar has risen in popularity. While less efficient (now) than traditional solar panels, thin film is cheaper to produce.

 Generates more energy than it consumes. The building’s aggressive approach to sustainability enables it to offer the lowest energy consumption per square meter for its class. The complex will utilize sustainable materials and feature integrated wind turbines, outdoor air quality monitors. In addition to serving as the Masdar headquarters, the building will accommodate private residences and ‘early bird’ businesses starting up in the city. The Masdar development will be constructed over seven phases and is due to be completed by 2016.

Island Wood: City Kids First Visit with Nature & Environmentalism
urbanlife
by urbanlife  2-22-2008   
 An environmental learning center—nestled into a rustic 250-acre nature preserve—plays a dual role as symbol and teaching tool. "We envision a future in which all people view themselves as lifelong learners, and share an extraordinary bond of stewardship for the environment, for their communities and for each other." Raising of environmental consciousness, one child at a time. “The center is primarily for inner-city kids who don’t have an opportunity to connect with the natural world. And when kids are uncomfortable, they’re not open to learning. So we wanted them to be as comfortable here as possible.” The mission of IslandWood is to provide exceptional learning experiences and to inspire lifelong environmental and community stewardship.
