The largest hydropower plant in the world is located in Washington along the Grand Coulee Dam. It took 11 years to build it from 1933 to 1942. Since that time it has undergone numerous facelifts and changes. It is amazing at a size of over 5,000 feet long and 550 feet high.

Switch to water heating systems that use solar power to heat hot tubs, pools and indoor water. Using electricity or gas to heat water is not terribly efficient, but water heaters that use solar power maintain water temperatures using only the sun’s rays by way of solar panels.

Naturally, if you live near a large city (we’re talking pollution here), you don’t want to use a cistern for your drinking water. Also if you collect water from your gutters, then you’ll want a clay or metal roof rather than a shingled one for cleaner water. But if you’re in an area where you get a lot of rain, this is a viable option for collecting water for bathing, laundry, watering your garden and even cooking and drinking – provided you have a filter system for your drinking water.
