Let there be LED light
Even energy-producing companies such as Duke and Progress recognize that they cannot reasonably continue the coal and fossil burning production forever. Therefore, they have been encouraging people to conserve energy in their homes by moving from old style incandescent lights to CFL to LED. However, the retail cost of LED has been very high. Now Duke customers have the opportunity to buy a wide variety of LED bulbs at a deep discount.
At website duke-energy.com/NewBulbs (or by calling 1-866.849.9704), you will find many types of CFL and LED lights at up to 92% off retail. For example, a 10W LED bulb that replaces a 60W bulb commonly used in table lamps costs only $3.75 with the discount, not $12.95 as in stores, and may last 10-20 years. A BR30 reflector bulb for recessed lighting costs $17 instead of $32 retail.
One strategy would be to replace the three to five light bulbs that you use most often. Maybe the lamp by your bed, or the over lights in the living room, or exterior lights that shine more at night. This would minimize cost and maximize the impact on your electrical bill. Later, replace three or five more bulbs. At the same time, become aware of turning off all lights and unplugging/turning off appliances when not in use.
