States that have been leaders when it comes to embracing state cap-and-trade green house gas emissions programs, are now facing a variety of hurdles due to state and federal politics, economics, and lawsuits.
Weird. New data released by NASA shows that the atmosphere above eastern Japan was flooded with electrons and heated dramatically in the days before the devastating March 11 earthquake.
China is clearly a clean-tech force to be reckoned with. It installed more wind power, manufactured more solar PV and solar hot water heaters, and spent more money overall on clean-energy investments than any other nation in 2010.
The Electric Power Research Institute has released a report that lays out energy storage technology options, benefits, performance and costs and how the different technologies play a role in everything from managing the electric grid to managing home energy use.
Wind farm development is playing a huge role in a clean energy future. While mass wind power may offer a beneficial energy alternative, the construction of wind farms creates a great deal of controversy – from the destruction of natural habitats and dangers to birds and bats to the actual effectiveness of wind as an energy source. Some even argue that wind farms are ugly, disrupting the scenic coastlines and natural beauty of the world. Take a look at these wind farm pictures and let us know your thoughts – ugly or simply amazing?
John Maynard Keynes, a giant in modern economic theory, pushed back on the notion that people behave in an purely economically rational manner. Can it help U.S. investments in clean energy?
While the rest of the world is getting dressed up for the clean energy party, it looks like the U.S. is going to stay home. In the clean energy world, countries like Germany and China are the real party animals, while the U.S. runs the risk of becoming increasingly confused and dispirited. By James Barrett
Measured by dollars invested, cleantech venture investment was up by 52 percent compared to the previous quarter ($1.69 billion) and was also 31 percent higher than the same period a year ago ($2.28 billion). Conversely, the number of deals recorded in 1Q11 was 159, a total which is likely to be the lowest quarterly count since mid 2009, though this tally may rise once all investors have completed reporting deals. Of these deals, 65% (104) were follow-on rounds, accounting for 93% ($2.39 billion) of all money invested during the quarter.
Solar panels are a great way to generate electricity without causing any harm to the environment, but the problem with them is that they require a large area to contain a huge amount of solar panels in order to generate sufficient amounts of electricity. Tata Power, India; and Sunergy, Australia; have decided to work together to create a solution to the problem: a Liquid Solar Array. Making use of specially designed floating solar panels, the Liquid Solar Array will be a whole fleet of sunlight converting devices that will float off-shore India, transforming rays from the sun into useful electricity. Watch the video render of how the Liquid Solar Array would function. Via www.scoop.it/masa
Or Solar Dreams? It's one thing to demonstrate photovoltaic activity and it's a completely different challenge for the innovation to be scalable, reliable, efficient, and cheap.
Explore the high-tech revolution's collateral damage—25 million tons of e-waste and counting, poisoned workers and a public left holding the bill. Host Annie Leonard takes viewers from the mines and factories where our gadgets begin to the horrific backyard recycling shops in China where many end up. The film concludes with a call for a green 'race to the top' where designers compete to make long-lasting, toxic-free products that are fully and easily recyclable.
Great video -- thanks for sharing. It makes me think about Arthur C. Clarke's quote, "Any sufficiently advanced technology is indistinguishable from magic." By designing with this possibility in mind we can ultimately remove all of the hardware from our technology and therefore eliminate e-waste. The germ of this idea of magic is found on the iPhone and iPad; the keyboard has been removed and replaced with a digital version. The plastic keys have been replaced by digital "magic" and therefore no longer generate e-waste. It's a small example of what Arthur C. Clarke is describing, but it is the future of design. The sooner we embrace this possibility, the sooner we will eliminate the tons of electronics waste generated by our hardware.
Palm Spring, California, March 14-15. For the fourth consecutive year, Greentech Media presents its successful Solar Summit. Bringing together leading solar companies, influential regulators and policymakers, forward-thinking utilities and bullish investors, the Solar Summit is the place where the industry comes to learn and do business. Powered by the research and economic analysis of GTM Research’s team, participants at this event gain access to the freshest, most innovative research on the maturing PV market.
Looking for a luxury electric car, with utter disregard for the price? Rolls-Royce has got something for you: the Phantom 102EX, an electric version of the company’s top-of-the-line model.
The car is powered by the world’s largest electric car battery, weighing 640 kg (1,400 lbs) and has a range of 125 miles, which is not bad for a large limousine such as the Phantom. The batteries can be charged quickly — in about eight hours — but if you want to conserve battery life, you’ll need to take the slower route and leave the car charging for more than 20 hours.
Different: Sensus is the only one of the big five smart meter giants that uses a licensed star network, rather than an unlicensed mesh network, to connect smart meters — a fact that could offer key advantages, as well as drawbacks. Read more.
It’s one thing for a small percentage of wealthy homes in California and New Jersey to get solar panels. It will be another thing entirely for India, with its 1.19 billion population, to make a substantial commitment to solar power.
Electric motorcycle maker Brammo has kicked up its bikes a notch - well, about 6 notches. No doubt it performs well. No doubt it's greener. I however wonder how bikers will react. Motorbike is so irrational, almost by definition.
A mixture of vacuum cleaner and blender ... Tron Legacy sauce. It is environmentally friendly for the future, a beautiful response to rising gasoline prices ... but it lacks the peculiar smell of oil, the legendary sound of a muffler carbon ... no, not yet.
A wake is the region of recirculating air flow immediately behind a moving solid body, caused by the air flow of surrounding air around the wind turbine.
Google seems to be hell-bent on world domination… in a safe clean way at least. The company has been reported to have invested $100m in the Shepherds Flat Wind Farm in Oregon. The latest investment follows previous investments in clean energy after the $168 million solar power tower last week, and the German solar plant the week before.
Global research firm Cleantech has revealed that global investment in green technology for Q1 2011 totalled $2.57b, with the solar sector accounting for $641m.
Leading investments: BrightSource Energy ($201m), MiaSole ($106m), Alta Devices ($72m), SoloPower ($13.5m).
That would just be fantastic. Renewable energy is often intermittent and unreliable, but with the right storage technology, it can become a substitute for baseline power.
A paper that will soon come out from the National Solar Energy Center in Israel hypothesizes that the country — which now only gets a tiny fraction of its power from solar — could conceivably boost the total to 90 percent with things like vanadium-redox flow batteries and pumped hydro storage.
It’s easy to forget how early startup Tesla was in terms of getting commercial EVs on the roads. Tesla Roadsters have driven a collective 10 million miles, which has saved 500,000 gallons of fuel and 5.3 million pounds of carbon emissions.
An initiative from Mario Caceres and Cristian Canonico of the Influx Studio in Paris, working with SHIFTboston, is looking to roll out a man-made forest of air-cleaning Treepods throughout Boston ... which are powered by solar and kinetic energy.
NEW YORK, March 3, 2011 /PRNewswire/ -- Recyclebank®, a green lifestyle community that rewards people for taking everyday green actions, today announced that it has taken the top spot on the Wall Street Journal's prestigious ranking of the Top 10 Clean-Tech Companies.

Elon Musk is not the most impressive speaker. But his speech about why and how he decided to build his company and its products is so articulated and meaningful.
