NRDC: Natural Resources Defense Council - The Earth's Best Defense
India Calling: The Green Cell Phone Revolution What if corporate executives and unschooled women in remote villages could join forces to change the world? In India, that may be happening -- thanks to the cell phone. George Black, executive editor of NRDC's award-winning OnEarth magazine, talks about his story for the Spring 2012 issue, online now .
California Cars Initiative for Plug-In Hybrids
CalCars is a non-profit startup of entrepreneurs, engineers, environmentalists and consumers. Since 2002, we've promoted plug-in hybrids (PHEVs) with large batteries. Local miles are powered partly or fully by electricity from standard plugs, and liquid fuel provides infinite range. PHEVs tackle energy security, jobs and global warming -- all at once. We built the world's first plug-in Prius using today's technologies and infrastructure .
EcoGeek - Brains for the Earth
A group of entrepreneurs has announced the formation of a new company called Planetary Resources with the goal of collecting valuable, useful minerals from asteroids. "Planetary Resources hopes to go after the platinum-group metals — which include platinum, palladium, osmium, and iridium — highly valuable commodities used in medical devices, renewable energy products, catalytic converters, and potentially in automotive fuel cells." The technology and information about asteroids is not in place for this to be undertaken immediately. The company plans successive levels of exploration , beginning with a series of private, orbital telescopes to be used to survey asteroids. This would be followed by spacecraft to intercept asteroids approaching Earth's orbit for further study and analysis, and then further deepspace explorer craft to study and gather information about more distant asteroids, and then finally get to the mining of minerals from the asteroids.Build It Green - Promoting healthy, energy- and resource-efficient building practices in California.

Sur Terre , l'énergie solaire est à l'origine du cycle de l'eau , du vent et de la photosynthèse réalisée par le règne végétal , dont dépend le règne animal via les chaînes alimentaires . L'énergie solaire est donc à l'origine de toutes les énergies sur Terre à l'exception de l' énergie nucléaire , de la géothermie et de l' énergie marémotrice . L'Homme utilise l'énergie solaire pour la transformer en d'autres formes d'énergie : énergie alimentaire , énergie cinétique , énergie thermique , énergie électrique ou énergie de la biomasse . Par extension, l'expression « énergie solaire » est souvent employée pour désigner l'énergie électrique et l'énergie thermique obtenue à partir de cette dernière. L'énergie solaire vient de la fusion nucléaire qui se produit au centre du Soleil . Elle se propage dans le système solaire et dans l' Univers sous la forme d'un rayonnement électromagnétique — de photons .
