How are those big shiny panels on the roof (or on your calculator or emergency street lights) actually generating electricity? The University of Texas at Austin Architecture and Engineering takes a looks at the basics of solar power and why energy from the sun is the next big thing.
Around 50 % of the world’s photovoltaic cell production was manufactured in Japan in 2003. United States accounted for 12%. On the supply side, the amount of product manufactured by PV cell manufacturers worldwide reached 742 Megawatts in 2003. Japan has taken over from the United States as the largest net exporter of PV cells […]
For billions of years, the sun has poured out huge amounts of energy in several forms, including light, heat, radio waves, and even x-rays. Now is the time we can use this energy for the good of our planet. Re-Energy provides links, downloads, and information on do-it-yourself solar power and the future of solar energy […]
Beacon Power goes through the mechanics of a typical home installation of a photovoltaic (PV) system used to power homes and offices.
Ecogeek reports on an Australian man’s invention for tracking the sun using a motorless tracking device. It uses a hydraulic system powered by the sun. The device works by absorbing heat from a combination of increasing ambient air temperature and direct solar radiation to provide an expansion of a liquid at a controlled rate. Increasing […]
