One of the criticisms you almost invariably hear, when discussing electric vehicles (EVs)Â is that there will be no net difference in carbon emissions, if large numbers of drivers switch from gas cars to EVs. Critics charge that carbon emissions will simply be released by coal power plants instead of tailpipes.
The coal emissions critique of EVs is fallacious on several counts, but here I will focus on one reason why gas cars and EVs will not be equivalent in carbon emissions: those interested in buying EVs are also likely to be interested in solar energy to power them. Manufacturers of EVs are already aware of this, and as a result, you see the electric car makers teaming with solar companies to create solar systems designed for electric cars.
Ford is teaming up with SunPower to offer a solar energy charging station, which will provied enough charge to power the EV for about 1,000 miles annually.
General Motors has partnered with Envision Solar to provide solar charging stations for the new Chevy Volt.
It should also be noted that retailers, such as Walgreens and Wal-Mart, are making plans to install electric charging stations in their parking lots. Think of Wal-Mart and Walgreens as the new Exxon and BP (minus the pollution).
