Of course. if the power plant was powered by solar or wind power, electric cars become much more practical.
_____ From: [email protected] [mailto:[email protected]] On Behalf Of John M. Steele Sent: 24 June 2011 11:41 To: U.S. Metric Association Subject: [USMA:50733] Tesla and MPGe rating MPGe is miles per gallon, equivalent, a new rating scheme by the EPA for electric and other technology vehicles not using gasoline or diesel. The article is about the Tesla Roadster (not Roaster, as in the article) and its rating. I understand why they chose kilowatt-hours per hundred miles (it is how your electricity is priced) but I would have preferred 108 MJ/100 mi, or, better yet 67.1 MJ/100 km, for direct comparison to other fuel and engine options. http://gas2.org/2011/06/23/the-mighty-tesla-and-mpge/ Of course it will always look much better than an internal combustion engine since the huge 30-40% efficiency hit for a heat engine is back at the power plant, not in the car. If they measured the fuel the power plant burned to make that electricty, it would be a fairer comparison.
