Reports show that over 3 quarters of all the properties in the US have cooling equipment. This same report details that cooling equipment uses about 6% of all the energy produced in total. As a result of all the cooling equipment in use, millions of tons of carbon dioxide are released into the atmosphere every year. Throughout most of the 20th century, nearly all cooling equipment used a particular chemical in the refrigerant that was later found by scientists to be easily damaging to the earth’s ozone layer. Most fortunately, the production of all air conditioner equipment made with that harmful chemical was halted, but the incredible destruction was already done. Nearly all cooling systems are made to use a peculiar refrigerant now, & even that chemical will be eventually phased out in the next decade.
