Hewlett-Packard has announced it will install a 1-megawatt solar array in its San Diego facility. The installation will be made up of 5,000 panels on seven buildings. It’s a large solar array, but smaller than Google’s 1.6-megawatt solar array, which is thought to be the largest corporate installation to date in the United States.
eSolar is one of the early-stage companies Google is working with. Google has announced a plan to develop sources of renewable energy that will be cheaper than coal. The new initiative, RE<C, (renewable energy is cheaper than coal) will begin by focusing on solar power technology, and will also encompass geothermal energy production. According to… [Continue Reading]
Air New Zealand and Boeing are secretly working to create the world’s first green aviation fuel, made of wild algae. The fuel is essentially derived from bacterial pond scum created through the photosynthesis of sunlight and carbon dioxide on nutrient-rich water sources such as sewage ponds.The company providing the biofuel is Aquaflow Bionomic Corporation. If… [Continue Reading]
University of Utah physicists 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. “We are converting waste heat to electricity in an efficient, simple way by using sound,” says Orest Symko, a University of Utah physics… [Continue Reading]
New York City’s fleet of yellow cabs will go entirely hybrid within five years, and all its vehicles for hire will have to meet new emissions and mileage standards by next year, according to Mayor Michael Bloomberg. The city said the increase in fuel efficiency will save taxi operators more than $10,000 per year. The… [Continue Reading]
The American Wind Energy Association (AWEA) today released its First Quarter Wind Power Market Report, announcing that the U.S. wind energy industry is on track to install over 3,000 megawatts (MW) of wind power in 2007, with Texas likely to account for about two thirds of the new installations.
Streetlights that adjust their light output according to the phases of the moon — this design idea was the winner of Metropolis Magazine’s Next Generation design awards. These streetlights would have light sensors built into them that are sensitive enough detect the brightness of the moon, and dim themselves accordingly. For example, if there was… [Continue Reading]
Wal-Mart launched a national ad campaign Wednesday touting environmentally friendly products like light bulbs and organic cotton pajamas, part of what analysts call a move by major retailers to test exactly how much demand there is from “green” consumers.
The cost of producing solar power will fall to that of coal-fired electricity by the end of the decade, according to a report by Europe’s Photon Consulting. However, falling costs of production won’t lead to substantially cheaper prices for consumers because of current market dynamics which see rising demand outstripping supply. The report predicts that… [Continue Reading]
From Live Science: Last year’s trash could become next year’s model home, thanks to the invention of a new type of construction material made entirely from waste products. “Bitublocks,” created by engineer John Forth of the University of Leeds in England, are composed of recycled glass, sewage sludge, incinerator ash, the by-products of metal purification… [Continue Reading]
