And air pollution. The small engines used in gas-powered lawn tools such as leaf blowers and trimmers are 2-stroke engines, which are extremely dirty engines from an air pollution standpoint. There are still some 2-stroke lawnmowers around, but they appear to all have moved to significantly cleaner 4-stroke engines which is possible because they're larger engines. I'm looking at going all battery power for my yard tools, save for the mower.
