FTR, I didn't buy battery powered landscaping tools or any other battery powered devices because of any "Green initiative". I bought them purely for ease of use, low operating cost, low maintenance and they are completely effective for my needs. If they wind up also being better for the environment that's great if not, I doubt they are any worse than petroleum powered tools. I am considering an EV car for the same reasons, the only green I'm concerned with in this decision is $$. I think the thought that "people who buy electric vehicles are motivated mostly by environmental concerns" is largely false.
