Elon Musk and Warren Buffett are fighting over market share in Nevada's utilities market.
EnGoPlanet is providing Sin City with LED street lights powered by the sun and pedestrians' footsteps.
A Koch brothers-funded group says that Tesla's Powerwall battery-storage system will take decades to store enough power to pay for itself.
Despite some claims to the contrary, green cars will get downright emerald when it comes to environmental friendliness, as electric production gets cleaner, according to a recent Natural Resources Defense Council blog post. Electric vehicles contribute as much as 53 percent fewer "cradle-to-grave" emissions than gas-powered vehicles, even factoring in such elements as the lithium that goes in
A woman in Florida learned a hard lesson to pay attention to police: While on her way to work, Kari Zimmerman saw police pulling over cars on a busy road in Boca Raton, Fla. Instead of pulling over as well, she drove around the stopped cars and on to a live downed power line.
One of the smallest US states continues to be one of the biggest proponents of electric-vehicle adoption, and is now offering special electric-use charging rates for folks who install EV charging stations. The Hawaiian Electric Co. (HECO) has received approval from the state's Public Utilities Commission to offer electric-vehicle pilot charging rates, in which businesses that install fast-charging stations get special, lower electricity-usage rates. Additionally, the state will allow HECO to ope
Coda Energy has been officially unveiled. As Coda Holdings, Inc., and its Coda Automotive electric carmaker subsidiary, has closed bankruptcy sale proceedings, the energy storage division is now ready for business.
Your Monday green-car buzzkill is brought to you buy University of Michigan research professor John DeCicco, who says more electric vehicles won't do much to slow global warming if energy-production methods aren't addressed.
Generating electricity through energy sources other than coal and nuclear is being debated in legislatures and board rooms around the world. In addition to natural gas, wind, solar and geothermal, there's one zero-emission energy source that we really don't hear much about: prisoner power. But it's real.
Quick, which is easier to find: a public charging station for an electric vehicle or a station that offers E85? Despite the much larger number of flex-fuel vehicles on the road, it turns out that when you bring the fight down to electricity vs. ethanol, EV drivers have nearly a 2-1 edge.
Few electric vehicles are actually "zero emissions," but calculating the exact carbon footprint of an EV can be daunting. Not only do different utilities each use a different mix of coal, nuclear, hydro, wind, and solar, many areas also offer individuals the opportunity to buy "greener" power. These deals don't actually guarantee the source of the electrons arriving at your home, but they can help ensure that your utility expands or purchases power from sources that are more environmentally frie
A Glut Of EVs Could Make America's Shoddy Power Grid Even Worse
Portland, OR strives to be the U.S. hub for plug-in vehicles. What other city has dedicated an entire block to plug-in vehicle charging? During a ceremony on Tuesday, Portland mayor Sam Adams plugged in the first vehicle at "Electric Avenue" and dedicated the charger-lined street. On display for the ceremony were plug-in vehicles from Nissan, Chevrolet and Eric Loveday
At some point in every engineer's academic career, they probably got to try their hand at creating an electric motor with parts that included a nail, a few feet of copper wire, and a magnet. If your own school days somehow missed this formative event, or if those times of yore are feeling a little distant, pop in after the jump to see a couple of motors that have been pared down to the absolute minimum. This
Operating an electric vehicle in China today emits more greenhouse gases than simply driving a gasoline-fueled equivalent, according to emissions expert Juerg Gruetter of Gruetter Consulting. The reason is that, despite the country's push to promote electric vehicles, China's power grid is so overwhelmingly fed by dirty coal that recharging the battery-powered rides will release far more emissions than just putting gasoline in the tanks of the nation's 200-plus million registered vehicles.
Back on July 14th, Takuji Yamada, Honda's chief operating officer of power product operations, made it known the Japanese automaker sees solar gas cogeneration technology as its "third pillar." What are the first two? Passenger vehicles and motorcycles, which means that cogeneration is about to become a very big deal indeed for Honda.
Back in December of 2009, Sustainable Business reported that no new coal-fired power plants were erected that year. In fact, SB indicated that 26 coal plant proposals had been either "defeated or abandoned." Well, it appears that the trend to shift away from coal power will continue.
