Tesla Powerwall Battery Economics: Almost There - "Elon Musk announced Tesla's home / business battery today. [video] tl;dr: It'll get enthusiastic early adopters to buy. The economics are almost there to make it cost effective for a wide market... That said, for large scale grid deployment (outside of the home), it still looks like flow batteries and advanced compressed air are likely to be far cheaper in the long run." [more inside]
The Economic Risks of Climate Change in the United States (PDF); prospectus (PDF); press coverage (YT) - "The signature effects of human-induced climate change—rising seas, increased damage from storm surge, more frequent bouts of extreme heat—all have specific, measurable impacts on our nation's current assets and ongoing economic activity. [The report] uses a standard risk-assessment approach to determine the range of potential consequences for each region of the U.S.—as well as for selected sectors of the economy—if we continue on our current path..."

Installed solar capacity is growing by leaps and bounds, led by Walmart and Apple, and helped by bonds backed by solar power payments,[*] which have sent industry stocks soaring, even as molten salt and new battery technologies come on line to generate storage for use when the sun doesn't shine. Of course we could always go to geostationary orbit -- or the moon -- as well we may (if politics allow it) as thirst from the developing world grows beyond the earth's carrying capacity.

Cloud services that power email and other technologies we use each day are themselves massive energy consumers. Gigaom reporters have written a pair of in-depth articles about efforts by Amazon and Apple to build infrastructure and source their own energy.
Eric Maundu - who comes from Kenya, now lives in West Oakland and is trained in industrial robotics- transforms unused spaces into productive, small aquaponic farms. He has taken the agricultural craft one step further and made his gardens smart. He explores new frontiers of computer-controlled gardening. More information about this story. His company, Kijani Grows. Via faircompanies.com.
Most of the talk about renewable energy is aimed at electricity production. However, most of the energy we need is heat, which solar panels and wind turbines cannot produce efficiently. To power industrial processes like the making of chemicals, the smelting of metals or the production of microchips, we need a renewable source of thermal energy. Direct use of solar energy can be the solution, and it creates the possibility to produce renewable energy plants using only renewable energy plants, paving the way for a truly sustainable industrial civilization.

Get the Energy Sector off the Dole - Why ending all government subsidies for fuel production will lead to a cleaner energy future—and why Obama has a rare chance to make it happen.
Peak Oil, 1925. In 2000, 20% of new buildings will be solar equipped. By the late 1990s, 90% of the world's energy will be nuclear-generated. These and other erroneous projections are being collected as part of the Forecast Project on the website Inventing Green: The Lost History of Alternative Energy in America.
Chris Goodall, author of Ten Technologies to Save the Planet, talks about the ten big green energy myths.
The Edison of our age? Stanford Ovshinsky may not be a household name, but his inventions have the power to change the world.
World solar challenge 2003. Darwin to Adelaide 19 - 28 October. Check out the route. Meet the teams. Have a look at the Green Fleet class as well, where technology meets reality. I won't be able to watch the race but have high hopes for next year's Olympics.
