Here is my experience with an electric golf cart. I have a Club Car cart, with 4, 12 volt batteries. The first set of batteries lasted 38 months (11,000 miles). A new set of batteries, Trojan, cost 618 dollars (Aug 2011). I purchased a Kill A Watt device last fall that records the KWH when the cart is being charged. So far I have driven the cart 1,644 miles and have used 326 KWH. At the current electric rate it amounts to 37.54 dollars. I have made a spread sheet and assuming I get 11,000 miles on the new batteries compared to 40 mph on a gas cart I am 16 % ahead with electric, with gas at 3.79 per gallon.
Of course there is maintenance costs that I didn’t include. Also gas has a much greater range compared to electric so it is up to each individual what is best for them.
