Sure thing! There will be a "Green Fee" for gasoline that I use in the generator to keep fresh batteries charged.My BIL has a landscape business that serves just north of portland, cumberland foreside, falmouth foreside and cousins island and he told me a few of his customers have asked that he convert his equipment over to all elect. He said no..lol
I don't know about the cost because that varies widely by region. I do know it would be a very inefficient process.I would love to see a cost breakdown for a landscaper for the price of gas for his equipment verse cost to run a generator to charge all his batteries during the day.
A little Honda running a strip of chargers.
Of course the extra cost would be passed on depending on the competition.
