Let that lawn go brown, or rewild your yardA brown lawn is not a dead lawn, so consider letting your lawn go. You can get a low-flow showerhead for as little as $15 or less, and the energy savings in hot water will pay that off fairly quickly. Install faucet aeratorsWater-saving faucet aerators help you cut down on water use, which will cut down on your electricity costs. Take shorter showersTake three minutes off your shower times and the savings, both in water use and in energy savings, will add up. Plus, an ENERGY STAR front-loading machine can cut water use by nearly 40% and electricity use up to 65% compared to a conventional top-loader.
