3. Solar-Powered Hot Water Heater
Speaking of solar power and water, you can save even more by using this sun-powered water heater. We all love a hot, relaxing shower. What we don’t love is the high cost of heating up that water, whether it’s electric or gas. By using the sun’s energy to back your hot water needs, your energy bills will take a nose dive, dropping as much as 50 percent, and you’ll still be helping the earth by saving resources. This gadget works by using solar power to heat your water and then storing that water in an insulated tank. It holds enough hot water for more than your showers, too. You can do your laundry and dish washing as well.
