Turn down your water heater thermostat
In a typical household, the water heater thermostat is often set to 140 degrees F. But did you know that 120 is usually fine? Why is this important for the earth? Well, according to Power Scorecard (founded by leading environmental organizations and scientists), each 10 degree reduction saves 600 pounds of CO2 per year for an electric water heater or 440 pounds for a gas heater. And here’s another interesting tidbit from their site: “If every household turned its water heater thermostat down 20 degrees, we could prevent more than 45 million tons of annual CO2 emissions - the same amount emitted by the entire nations of Kuwait or Libya.” Pretty impressive. Today, challenge yourself to check your water heater and lower it to the most energy efficient level.
