Global Solar Photovoltaic Industry Likely Now a Net Energy Producer

For the first time since the boom started, the electricity generated by all of the world’s installed solar photovoltaic (PV) panels last year probably surpassed the amount of energy going into fabricating more modules, according to Michael Dale, a postdoctoral fellow at Stanford’s Global Climate & Energy Project (GCEP). With continued technological advances, the global PV industry is poised to pay off its debt of energy as early as 2015, and no later than 202

Guest Post: Green Roofs Boost Efficiency of Buildings and Photovoltaic Panels

Planting a green garden on the roof of a building can help increase its energy performance; the vegetation infrastructure of soil, insulating and waterproof material and the vegetation itself, form an effective insulation layer on the roof of the building. Considering that the roof constitutes the primary source of energy waste in a building it is evident that planting a garden on the roof will effectively reduce unwanted energy gains from radiation in summer and reduce internal heat losses in winter – see green buildings: Rational solutions.

New Solar Structure Cools Buildings in Full Sunlight

A team of researchers at Stanford has designed an entirely new form of cooling structure that cools even when the sun is shining. Such a structure could vastly improve the daylight cooling of buildings, cars and other structures by reflecting sunlight back into the chilly vacuum of space. Their paper describing the device was published March 5 in Nano Letters.
