If you grow short plants, you should definitely try LEDs. 1  The first series of costs on the chart represents an electricity cost of $0.12/kwH, or 12 cents per kilowatt hour (a kilowatt hour is 1,000 watts being used for one hour). 2  $0.12/kwH was the US national average cost for electricity in 2011.
2. Buy smarter bulbs. An LED light bulb costs as little as $5 at home improvement stores, and it can save more than $100 over its lifetime. LEDs use up to 85 percent less energy to deliver the same amount of light as incandescents, and they come in many different shapes, colors, and intensities.
