1. Install Low Flow Shower Heads. They use less hot water, cost $10-$20 each, and deliver an invigorating shower. This will save 300 pounds (136 kg) of CO2 per year for electrically heated water or 80 pounds (36 kg) for gas heated water.
2. Put a Brick in the Holding Tank to conserve toilet water. Less water will be used to fii it, therefore, less to flush. Also, you can fill a jar with water to the jar's rim and put it in the tank.
3. Use an egg timer to conserve shower water. Set this when you take showers to limit your time to 5-10 minutes.
4. Take a Shower Instead of a Bath. A shower takes up to four times less energy than a bath.
5. Don't Leave the Water Running. Most people know by now that when brushing your teeth you shouldn't leave the water running, and only turn it on when you need to rinse. But, most don't always consider that an option when taking a shower. Turn the water off when you lather your hair, then back on to rinse.
