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 into EV batteries. The NRDC argues that EVs are the "cleanest vehicles on the road today" and – more
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
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
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 Mitsubishi and charging stations from Eaton, Ecotality, General Electric, OpConnect, Shorepower Technologies, and SPX.
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 video doesn't exactly describe what happens in an electric car, but it does show off som
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.
Last July, the Wall Street Journal reported that China had overtaken the U.S. to become the world's largest energy consumer. According to the WSJ, data gleaned from the Paris-based International Energy Agency (IEA) confirmed that China's energy consumption surpassed all other nations. The IEA's report showed that China had consumed 2.252 billion tons of oil equivalent in 2009 (a metric that's used to represent all forms of energy consumed, including crude oil, nuclear power, coal, natural gas an
The U.S. has relied upon conventional energy sources to meet our electrical demand for a long, long time. While conventional energy sources rarely failed to keep up with our burgeoning electrical demand, the recent interest in renewable energy sources may actually push supply beyond our needs.
