Otherwise, they become unbalanced and can damage both the mower and its master. Jim also reminded us to mention electric mowers, which are quieter, create less uncontrolled pollution and need far less maintenance than gas powered models. Without a heavy engine, they tend to be lighter and thus easier to handle, too. We once again drive big cars, and do so farther and at faster speeds. As a result, fuel efficiency erodes and gas consumption increases.
Prices tend to increase, too, as demand exceeds supply.
As for that tax roll-back, it's not going to help much, since it translates to a weekly savings per car of just under 64 . In fact, gas tax rollbacks could conceivably hamper energy efficiency efforts, since portions of the monies raised from these taxes go to state programs that improve transportation infrastructures or promote mass transit. The savings to both the ecology and your personal economy are considerable, as shown in the table. So when it comes to gasoline, the best way to save both money and energy is to think light and think small. It wouldn't hurt to properly inflate your tires, get a tune-up and take the bus, either.
