Unlikely City Claims Nation’s Largest Electric Car Share

Retirado do site GreenTechMedia:
"Katherine Tweed: June 13, 2013
Far from high-tech Silicon Valley or hipster Austin, Texas, the largest all-electric car-sharing service is being built.

If your second guess is Portland or Brooklyn, keep guessing…and moving inland. Indianapolis, the nation's twelfth largest city, will install 1,200 charging stations at about 200 locations to support 500 electric vehicles. The project is expected to be up and running within a year.

Indianapolis is hardly a hotbed of alternative transportation. It does have a bus system, but “we have one of the worst ranked bus services in the country for a city our size,” said Paul Mitchell, president and CEO of Energy Systems Network (ESN), a nonprofit clean technology initiative that is working on the EV project in Indianapolis. It was not one of the twenty-one metro areas chosen by the Department of Energy as part of the EV Project.

Electric Bus Picks up Passengers ... and Energy


"Tom Lombardo posted on March 18, 2013

Many years ago I bought a rechargeable battery-operated toothbrush with its own charging cradle. I noticed that there were no electrodes on the toothbrush or the cradle, and for a moment I wondered how it charged through the plastic. In a flash of inductive reasoning (sorry - I couldn't resist) I realized that the charging cradle and the toothbrush must be magnetically coupled. (This was long before iPhone charging pads.)

Soccket: Amazing Energy-Generating Soccer Ball Launches on Kickstarter!

Retirado do site StumbleUpon:

"By Lidija Grozdanic, 03/02/13

The kinetic energy-generating Soccket soccer ball produces power from play - and it's set to bring energy to off-grid locations around the world! After a year of building prototypes and conducting pilot programs, Uncharted Play just launched the energy-harnessing soccer ball with a fresh new design and a Kickstarter campaign. Developed by a group of Harvard alumni, the Soccket ball can generate three hours of electrical power from just 30 minutes of soccer play, and it offers an eco-friendly alternative to unsafe and unreliable energy sources often used in poor communities around the world.

U.S. Nuclear Industry Withers as Wind Hurts Prices


"By Julie Johnsson and Naureen S. Malik on March 11, 2013 Exelon Corp

A glut of government-subsidized wind power may help accomplish a goal some environmentalists have sought for decades: kill off U.S. nuclear power plants while reducing reliance on electricity from burning coal. That’s the assessment of executives and utility experts after the U.S. wind-energy industry went on a $25 billion growth binge in 2012, racing to qualify for a federal tax credit that was set to expire at year’s end.

Nuclear Industry Withers in U.S. as Wind Pummels Prices

Wind-generated electricity supplied about 3.4% of U.S. demand in 2012 and the share is projected to jump to 4.2% in 2014, according to the U.S. Energy Information Administration.

New report: U.S. Solar market grew 76% in 2012


The solar industry in the US added a record 3.3 GW of Capacity last year...

The report, Solar Market Insight: Year-in-Review 2012, jointly published by GTM Research and the Solar Energy Industries Association (SEIA), found that solar was the fastest growing energy source in the U.S., with 3,313 megawatts (MW) of solar photovoltaics (PV) installed in 2012.

Even with the cost of solar falling for consumers, the market size of the U.S. solar industry grew 34 percent from $8.6 billion in 2011 to $11.5 billion in 2012. As of the end of 2012, there were 7,221 MW of PV and 546 MW of concentrating solar power (CSP) online in the U.S.
