3 tips to reduce your electricity bill

  1. Switch to LED bulbs — they use up to 80% less energy than incandescent and last longer.
  2. Unplug idle devices — standby power ("phantom load") can add up to 10% to your monthly bill.
  3. Run the washing machine on full loads with cold water; fewer cycles means fewer kWh.
