However, they generate large amounts of greenhouse gases, and options that don’t alter local weather change are being sought. The American Council for an Energy-Efficient Economy reported in 2012 that throughout nine pilot studies involving real-time energy consumption feedback using smart meters, the average savings was 3.8 p.c. Solar water heaters come in a wide variety of designs, all of which include an energy collector and a storage tank. They use the sun’s thermal power to heat water and are usually described based on the sort of collector and the circulation system. Water heaters are sometimes categorized by the sort of gas that powers them and by whether or not they heat a storage tank or provide heated water on demand (also generally recognized as “tankless” systems).
