With summer coming to an end, it’s time for many of us to put away our air conditioners, or shut them down for the season. That takes care of one significant contributor to our monthly energy bill. According to the DOE, air conditioning is responsible for roughly 5% of all the electricity produced in the US. It also accounts for roughly 9% of the energy used in a “typical” home, though, of course, that will vary widely by location. In commercial buildings, where equipment as well as people can have cooling needs, that number can be as high as 14%.
It’s true that here in the Northern Hemisphere, heating exceeds cooling as a portion of our energy footprint. But as we look to the future, much of the world that has yet to be developed is in the South. This portends a major rise in AC demand. According to the PBL Netherland Environmental Assessment Agency, global demand for cooling will exceed that for heating well before the end of this century.
