Dirty Mathematics

Dirty mathematics makes a mockery out of clean energy on which electric vehicles (EVs) depend.

China puts together a typical Tesla lithium-ion battery on the coal-fired power grid. That alone releases 13,500 kilograms of CO2 emissions equivalent to the carbon pollution released by a conventional gasoline-powered car traveling 33,000 miles. This is a carbon-intensive manufacturing process, whichever way you slice it.

Also, most EVs are out and about during the day, right? That means solar-generated electricity won't be available for recharging them when nightfall comes. If and only if you happen to live in a solar panel-covered desert, then you may be able to reserve enough recharging power after sunset. Now, don't tell me that you have already set up a wind turbine in your backyard.

More than likely, an EV dealer's sale pitch is meant to cover up the devil that is always in the details. Clean-and-green buyers beware.
