We all know that water has a very important role in our lives. We use it to drink, to cook our food, to bathe and brush our teeth, and to water our plants or pets. But water affects our lives in so many other ways we might not think about. Check out these 5 unique ways that you use water!
1. Heating and Cooling. Many homes and businesses are using something called “geothermal energy” to heat and cool their buildings. “Geo” means “from the earth” and “thermal” means heat so this type of energy uses the heat from the under the ground to regulate the temperature of a particular system. Buildings that use this system pump a liquid, often groundwater, through a series of pipes and devices like “heat exchangers” to use the natural heat from the earth to warm up the air inside. During hot summers, a geothermal system can also cool down the air by working in reverse, absorbing the heat from inside and moving it back down into the earth. This very efficient system costs less than other modern systems and almost none of the energy is wasted.
