India's Waste-To-Energy Plan Could Mean Bad News For Trash Pickers. How much energy does the U.S. waste? We must save all the energy we can!
At the broadest level, everything we can do to address climate change/national security/energy balance of trade and just about any other meaningful social question associated with our energy use falls into one of three categories: 1. Energy. BedZed Exhibition Centre. BedZed (Beddington Zero Energy Development)is the UK's first and largest carbon neutral eco-community.
Situated in the South London borough of Sutton, BedZed provides 100 comfortable and futuristically-styled homes with community facilities and workspace for another 100 people, without contributing any extra CO2 to the atmosphere. BedZed was developed by the environmental entrepreneurs, Bioregional, in partnership with the Peabody Trust, designed by Bill Dunster Architects and completed in 2002. CLEVEL – changing culture not climate: Rocky Mountain Inst (rockymtninst) Green. Green Initiatives. Solar cell. Solar cells can be used in devices such as this portable monocrystalline solar charger.
A monocrystalline solar cell A solar cell (also called a photovoltaic cell) is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect. It is a form of photoelectric cell (in that its electrical characteristics—e.g. current, voltage, or resistance—vary when light is incident upon it) which, when exposed to light, can generate and support an electric current without being attached to any external voltage source, but do require an external load for power consumption. The term "photovoltaic" comes from the Greek φῶς (phōs) meaning "light", and from "volt", the unit of electro-motive force, the volt, which in turn comes from the last name of the Italian physicist Alessandro Volta, inventor of the battery (electrochemical cell).

MIT creates solar cell from grass clippings. Could Battery Advances Mean a Better Robot?: Scientific American. Every robot has its limit.
For the famous Roomba vacuum, it's two to three hours. For the several thousand robots deployed in Iraq, about the same. For the warehouse robots sorting our sneaker orders, eight hours. And the Energizer Bunny? Forget about it -- a few minutes, tops. A Guide to Recent Battery Advances. Electric vehicles, hybrids, and renewable energy have at least one thing in common–if they’re ever going to be more widely used, representing the majority of cars on the road or a large share of electricity supply, batteries need to get significantly better.
Batteries will need to store more energy, deliver it faster and more reliably, and ultimately, cost far less. The specific ways batteries need to improve vary by the application, but in all these areas, researchers have been making significant headway. Last week, MIT researchers led by Yang-Shao Horn , a professor of materials science and engineering and mechanical engineering, and Paula Hammond, a professor of chemical engineering, announced a new approach to high-power lithium-ion batteries, the type that’s useful for hybrid vehicles or for stabilizing the electricity grid. High-power batteries accept and deliver charge rapidly. In hybrids, the goal is to supplement the gasoline engine, allowing it to run at its most efficient. Wave Hub.

World’s Most Efficient Solar Collector. What does a Solar Collector and a Sterling Engine have in common? Well if you mention them together with a company named aptly enough – ‘Stirling Energy Systems’/ Tessera Solar you will undoubtedly be talking about the Maricopa Solar Project and their SunCatcher concentrating technology. The Sun Catcher consists of an array of curved glass mirrors arranged in a parabolic dish shape for the solar collector . Instructables - Make, How To, and DIY.

Cool Environmental News, Green Design and Eco-Living Tips From Around The Globe! Easy sources of alternative energy: Helioculture. Appliance Efficiency and Long-Run Energy Demand. Appliance Efficiency and Long-Run Energy Demand Matthew Harding (PI), David Rapson (PI) This project will examine how people make decisions about appliance purchases and the effect that these choices have on energy demand.
Currently, approximately half of U.S. greenhouse gas emissions are attributable to residential appliance use. However, consumers can reduce their long-run energy needs by replacing old appliances with ones that are more energy efficient. It is not surprising, then, that efficiency standards have been the cornerstone of U.S. energy conservation efforts to date. We will use the latest econometric techniques on existing data to model the complex dynamic decision faced by consumers when choosing appliances. New battery could change world, one house at a time. In a modest building on the west side of Salt Lake City, a team of specialists in advanced materials and electrochemistry has produced what could be the single most important breakthrough for clean, alternative energy since Socrates first noted solar heating 2,400 years ago.
The prize is the culmination of 10 years of research and testing -- a new generation of deep-storage battery that's small enough, and safe enough, to sit in your basement and power your home. It promises to nudge the world to a paradigm shift as big as the switch from centralized mainframe computers in the 1980s to personal laptops. But this time the mainframe is America's antiquated electrical grid; and the switch is to personal power stations in millions of individual homes. Third-World Wind Power: First Look - StumbleUpon.
La desaparición de los arrecifes de coral es un problema para la sociedad. 2.600 científicos alertan de la rápida disminución de los arrecifes de coral en el mundo, recordando que requieren un esfuerzo mundial para salvar lo que queda.
Con los arrecifes de coral de todo el mundo en rápido declive es imprescindible hacer todo lo posible para salvar lo que queda de ellos, afirman los investigadores marinos que se reunieron recientemente en Australia con motivo del XII Simposio Internacional sobre Arrecifes de Corales. En una acción sin precedentes, 2.600 investigadores marinos de prestigio de todo el mundo hicieron pública la Declaración de Consenso sobre Cambio Climático y Arrecifes de Corales. Esta declaración requiere un esfuerzo a nivel mundial para superar las crecientes amenazas que afectan a los ecosistemas coralinos y para la subsistencia de millones de personas que dependen de ellos.
Proponen medidas para hacer frente al aumento de temperatura del mar, la acidificación de los océanos, la sobrepesca y la contaminación terrestre.
