And the benefits go beyond cars. I would like to replace all my tools with electric motors but the energy density isn't there yet. I just got back inside from cutting down a 5.5" diameter tree branch that fell on my electric fence with a battery powered reciprocating saw. I need to go back out when the battery recharges (had to cut multiple large limbs) to get one more branch.
I have gas chainsaws, but I prefer the electric saw because it's much quieter, much lighter and easier to maneuver. I'm waiting for the day when I can buy a battery that lasts as long as a tank of gas.
I am quite happy that the cost is dropping though.
I have a battery electric chainsaw that would have eaten that branch for lunch. I don't get the chance to use it very often, but it's a joy when I do. It won't take down mature trees, but I'd have to get permission from the city and a certified expert for that anyway. It will limb just about anything.
The best decision I ever made powertool-wise was sticking with a single line of tools for both construction and yard tools, so I have at least 10 or so batteries that fit in every tool I own. I have drills, saws, nailers, lights, leaf blower (that thing drinks battery), hedge trimmer, weed whacker, and the chainsaw all ready to take the exact same battery. One thing I've never had to do is wait for a battery to charge.
