Action - Lower water-heater temperature
In the average home, the hot water heater is set much higher than is necessary or desired. Many homes have it set well over 55C or 140F but water this temperature is never actually used. In the shower or sink it's normally mixed with cold water. Most people are happy with water under 45C or 120F, which will save a good amount of CO2 emissions and money.
