Energy Saving Tip

Turn off your lights when you leave the room—even if you'll only be gone for a moment. Contemporary light bulbs require very little energy to turn "on."

Gas Meter Safety

Keep your natural gas meter dry and clear of snow and ice at all times to avoid the potential for dangerous indoor natural gas buildup.
