In the fall, the facilities workers at my agency use leafblowers to clean up the outside of our building. These leafblowers are not only expensive to buy (or rent) and to repair, but they waste energy and contribute to both air pollution and noise pollution.
Why not replace those leafblowers with good old-fashioned rakes? Rakes are less wasteful, not just when they're being used, but also when they're being manufactured. Of course, they're also much quieter. And, for multiple reasons, using rakes would be better for the health of the people on the facilities staff than leafblowers. It's a win-win-win!
