1. Cleaning or replacing air filters as recommended can save 5% of the energy used or up to 175 pounds of CO2. Energy is usually lost when air conditioners and hot-air furnaces have to work harder to draw air through dirty filters.
2. Setting the thermostat to 68 degrees during the day and 55 degrees at night during the winter. Keeping the thermostat set to 78 during the summer can result in serious energy savings. Lowering the thermostat just two degrees during winter can save 6% of heating-related CO2 emissions. That is roughly 420 pounds of CO2 per year in a typical home.
3. When replacing outdated or old models look into the Energy Star Label. Only buy products that are sized to one’s needs. Typically front loading washing machines will cut hot water use by 60-70%. Replacing a 1973 refrigerator with a new energy-efficient model saves 1.4 tons of CO2 per year. Investing in a solar water heater can save up to 4.9 tons of CO2 annually.
4. Setting the clothes washer to the warm or cold setting can save nearly 500 pounds of CO2 per year for an electric water heater or 150 pounds for a gas heater.
5. Not running the dishwasher until it is absolutely full as well as using the energy saving setting can save about 20% of the dishwasher’s total electricity use.
6. Refrigerators account for about 20% of household electricity use. Turning the refrigerator down and assuring that the energy saver switch is turned on can help conserve energy in the home.
7. Turning down the water heater thermostat to 120. Each degree reduction saves 600 pounds of CO2 per year for an electric heater, or 440 pounds for a gas heater. This can help prevent more than 45 million tons of annual CO2 emissions.
