Lets look at another example. I got an eletcric drill as a high school graduation present. It was a very high end Black & Decker with two speeds and an aluminum case. It survived decades of projects. A few years ago I bought a Sears battery powered drill. I never use the old plug in drill, even though I still have it. The battery operated drill is much easier to use.
The same thing is coming with more and more powered tools. They will be adapted because they're are a better all around product, not because they are green. The same will be true for cars and larger vehicles as the battery technology improves. Yesterday my car used a little less than 30 kilowatt hours per 100 miles That's equivalent to 122 miles per gallon. To get the EPA range of 310 miles it would need to only use around 25 watt hours per 100 miles or 146 miles per gallon. That's never going to happen with my driving style. At $0.115 per kilowatt hour that means it costs $0.00345 per mile. A 30 mile per gallon car will cost $0.12 per mile with $3.60 per gallon gasoline.
