General Energy Saving Tips

Switch to LED bulbs

LED bulbs use up to 85% less energy than incandescent and last 25x longer.

Use smart power strips

Eliminate phantom load from devices on standby. Can save 5-10% on your bill.

Adjust thermostat by 2 degrees

Each degree saves about 3% on heating/cooling costs. Use a programmable thermostat.

Run full loads only

Dishwashers and washing machines use the same energy regardless of load size.

Air-dry clothes when possible

Dryers are one of the biggest energy consumers. Air-drying is free.

Unplug unused chargers

Phone and laptop chargers draw power even when not connected to a device.

Clean HVAC filters monthly

Dirty filters force your system to work harder, using 15% more energy.

Use ceiling fans with AC

Fans let you raise the thermostat 4 degrees without losing comfort.
