Electric cars are much, much greener than gas cars (“gasmobiles,” as I like to call them). Even in the state with the dirtiest electricity grid (Colorado), electric cars charging from the grid have a miles per gallon equivalency of 34. The average new gasoline-powered compact car has a fuel economy rating of 28 mpg. (In the cleanest state, New York,

Solar power systems are ideal for buildings with large, flat roofs. That type of building is universal in public schools in the US. Thus, public and private schools offer huge, mostly untapped potential to increase solar energy use in the US. Installing rooftop solar photovoltaic (PV) and solar thermal systems on US schools just makes so much sense. Initiating progress

Editor’s Note: I remember seeing a presentation at EVS27 in Barcelona last year that also found rapidly recharging lithium-ion batteries wasn’t as harmful to the batteries’ capacities as was widely assumed. With another study coming to the same conclusion, combined with some stories of Teslas traveling tens of thousands of miles and just losing a little bit of their range,

By examining how tiny particles in a lithium ion battery electrode behave the researchers have shown that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as had been thought and that the benefits of slow draining and charging may have been overestimated. The findings also suggest that scientists may be able

TUV Rheinland recently issued its first Potential Induced Degradation (PID) test certificate in Greater China. New Duo-Max module (the PEG14 and PDG14 series) from Trina Solar Limited (TSL) successfully passed the most stringent PID test and received the quality certification. This is a significant achievement, as it is the first PID certificate issued by TUV Rheinland in Greater China, and

A new study investigating wind power and grid resiliency by GE’s Energy Consulting business in late-August found that wind power can substantially enhance grid resiliency when coupled with appropriate modern plant controls. Scenarios where the US electrical grid suffered large-scale interruptions, such as multiple power plants tripping offline, were the catalyst for GE’s research. GE’s study explored how the US

The Polish town of Kisielice has received the European Commission’s ManagEnergy Award 2014 for its clean energy leadership. It is 100% powered by renewable energy (wind and biomass, to be specific). The prize is to award outstanding local and regional sustainable energy projects. Kisielice’s submission was titled, “Energy self-sufficient Commune of Kisielice.” Mayor Tomasz Koprowiak of the small community in

(Reuters) – Renault plans to build its Fluence electric car in China and is discussing the proposal with Chinese authorities, Chief Executive Carlos Ghosn said on Monday. With government approval, “Renault is ready to build the Fluence in China” for an unspecified Chinese brand, Ghosn told reporters at a test-drive event in Nantes, western France. Renault and partner Dongfeng Motors

The battery could be used for many applications including as a reliable energy source in automobiles or for space flight. “Betavoltaics, a battery technology that generates power from radiation, has been studied as an energy source since the 1950s,” said Jae W. Kwon, an associate professor of electrical and computer engineering and nuclear engineering in the College of Engineering at
