10 Ways to Save Energy This Summer
The summer heat can lead to increased demand on our energy supply. When we use less energy, there’s less need to generate electricity. By managing our energy use, we can help control energy costs and reduce carbon emissions as we work together to achieve net-zero carbon electricity by 2050.
Simple steps to save energy:
- Use a qualified contractor to professionally maintain your heating and cooling system at least every two years. And, be sure to clean leaves and grass clippings off your outdoor cooling unit.
- Limit or avoid running major appliances between 4 and 9 p.m. during the cooling season. This helps lower the demand for power during peak times.
- Don’t overcool with your air conditioner. Set your thermostat as high as is comfortable, preferably 78˚F or higher when you are home and up to 85˚F when you are away. Make sure to set the fan to “auto.” If it’s set to “on,” the fan will run 24/7.
- Swap your lightbulbs with LEDs, which use up to 75% less energy than standard incandescent bulbs and last 15 to 25 times longer.
- Unplug your phone chargers, printers, computers and other electronic equipment when not in use or opt for a smart power strip that reduces standby power. These devices still can use energy when not in use and can account for 5% to 10% of your total energy use.
- Run room fans or ceiling fans. Be sure to turn them off when no one is in the room—fans cool people, not rooms. And, be sure to run your bath fan during and after showers or baths to remove humidity.
- Seal around your window air conditioner so cool air cannot escape. If you need to purchase a new unit, consider a Wi-Fi-connected window air conditioner, which can be controlled remotely using a smartphone. Always look for ENERGY STAR® certified products for energy efficiency.
- Keep your window coverings closed in summer to block out direct sunlight during the day.
- Run full loads in your washer and dryer to cut down on excess energy usage.
- Keep your water heater temperature set at 120°F, and if you go on vacation, remember to switch it to vacation mode.
