Moje mišljenje (in kot kaže mišljenje mnogih) pa je, da so elekrični avti brez izpustov emisij CO2. Pri avtih s pogonom na bencin ali nafto, se izpusti merijo v izpušnih plinih. Teh pri električnih avtih ni. Če pa hočete upoštevati izpuste pri pridelavi električne energije, pa ne vem, zakaj tega ne storite tudi za avte na fosilna goriva, kajti tudi tam je treba pridelati bencin in poskrbeti za dostavo do črpalk...

Renault's home auto show in Paris this fall will mark the beginning of a new styling direction for the brand and that means a new concept car. The DeZir is the first major project under new design VP Laurens van den Acker and according to Renault it represents the vision of 'simple', 'sensuous' and 'warm'. The shape certainly fulfills the first two elements and the bright red finish is downright hot.

The DeZir wouldn't be a modern Renault concept if it wasn't powered by electrons and such is the case for this coupe. Energy storage comes by way of the same size 24 kilowatt-hour lithium ion battery pack that sits under the Nissan Leaf and the driving range remains the same 100 miles. Unlike the Leaf, the pack in the concept is configured for Quick Drop exchanges.

Propulsion is provided by a 110 kilowatt electric motor spinning the rear wheels and pushing the 1,830 pound concept to 60 mph in five seconds (at least according to the spec sheet). Kevlar body panels are wrapped around a steel tube frame chassis with double wishbones at all four corners. Renault hasn't given any indication yet if the DeZir will be produced.

Earlier this year, Honda unveiled its newest prototype home hydrogen station for fuel cell vehicles. Susan Carpenter of The Los Angeles Times recently drove over to Honda's Torrance headquarters to check out the unit installed there. The system consists of three components: a vehicle filling unit, an electrolyzer to split tap water into hydrogen and oxygen and a six-kilowatt solar array to power it all.

The whole system can generate about 0.5 kilograms of hydrogen from eight hours of sunshine. That's enough for about 30-35 miles of driving, which should meet most people's daily commuting needs. If they need to use the full 270 mile range of the FCX Clarity, they'll have to stop by one of the handful of hydrogen stations in the Los Angeles area for a complete fill-up that takes about five minutes.

Toyota and Tesla have officially announced that the electric prototypes being developed by the California startup are based on the RAV4 crossover, and the two companies hope to have a production version ready by 2012. When we sat down with Toyota CEO Akio Toyoda last week, he revealed that an initial prototype was being built with a Tesla electric powertrain. Since then, Tesla CTO JB Straubel revealed that his engineering team was preparing two vehicles based on an existing Toyota platform for delivery by the end of July.

The long-running legal battle between Toyota and Alex Severinsky over who "invented" a critical piece of hybrid technology is heading into a new phase. The automaker and the Russian engineer will be making their respective cases before International Trade Commission judge Theodore Essex to determine if Toyota can continue to import its hybrid vehicles into the United States.

Just moments after we published our earlier report about today's scheduled hearing between Toyota and Alex Severinsky at the International Trade Commission, we got word that the parties have settled. The parties haven't released any details and they probably won't.

This will likely be the favorite screen for most drivers. All EVs have a power use gage of some sort, on which their drivers focus – initially out of necessity, then, as they become more comfortable with the car's range, out of interest. Ultimately, the gage is used to maximize range, often in competition with other drivers; the EV crowd was hypermiling long before the word made it into common vernacular. Still, there are always questions about how much energy the HVAC system uses, or radio, or headlights, even though most accessory use won't affect range, and even climate control is a distant second to one's right foot. Threads on EV forums delve into whether it's better to use AC or roll down the windows, and so on. While most drivers never see their battery's "state of charge" gage hit "empty", the more adventurous among us have all eked out the last few miles to the next stop in a sweltering car on the off chance that a little air conditioning might make the difference between getting there and not.

At the Plug-in 2010 Conference in San Jose, CA today, Nissan North America's executive vice president, Carlos Tavares, announced that the Leaf's battery pack will be covered by an 8-year, 100,000-mile warranty – exactly what Chevrolet is offering on the Volt pack. He said that feedback from people interested in the Leaf was important in setting these levels, so that explains why Leaf handraisers got those email surveys about this topic recently.
