The source of nearly all of our energy is the sun. While we might use wind, oil, and rivers to help empower our world, all of those sources of energy are also made possible through the sun. Because it won’t stop burning anytime soon, we can effectively consider it an infinite source of energy and better yet, it’s completely free for absolutely anyone to use. To get the biggest savings possible on your next energy bill, a passive solar water heater will use the sun’s rays, saving you hundreds of dollars a year. Just One Step to Protect the Environment a passive solar water heater is certainly smart for the environmentalist, but it also makes sense for any home owner. It’s estimated that ten percent of all home energy usage goes into water heating. If every conventional water heater was replaced with a passive solar water heater, the energy savings would be incredible; saving at least 3-4% off the world’s energy needs each year. While 3-4% doesn’t sound too large, keep in mind that this could be just one step towards making the world energy independent.
