The cost of turning off a single lightbulb does not amount to noteworthy savings. However, the cost when looking at the total number of bulbs in your home is more substantial. On average American homes have 40 lightbulbs, and the energy to power those accounts for 20% of the average electric bill. When ten incandescent bulbs are left on for an hour each day, the resulting cost is $24 each year. The expense for having ten halogens left running an hour daily is $17 annually. It is $6 annually to leave ten compact fluorescents running for a single hour every day. Leaving ten LEDs on for an hour daily equates to a net cost of $5 a year. These figures when multiplied show how much it truly costs to light your home, and the savings from turning the lights off when you leave the room.
When turning off your lights you may be saving energy, but the cost effectiveness of this is dependent on the type of light bulb used. Each style of bulb differs due to their individual rated operating life, which is impacted by the number of times the light is turned off and on. With every additional flipping of the switch, the functioning lifespan of the bulb is shortened. The Department of Energy compared the electricity usage and expenses of four 60-watt equivalent bulbs. A single Incandescent bulb employs 0.06 kWh of electricity in an hour. Each one consumes roughly $6.60 in electricity in a year. This number is calculated by the cost per kilowatt hour of $0.11 for one thousand hours of operation. This is the least efficient method of lighting, so these bulbs should be turned off whenever possible. A 43-watt halogen lightbulb is able to save 25% more energy than an incandescent. In 1,000 hours of usage, the cost of one bulb is typically $4.73. Replacing an incandescent bulb with a single 15-watt compact fluorescent will cause 75% less energy to be used. The compact fluorescent has an operational cost of $1.65 per 1,000 hours. An LED bulb provides 80% higher efficiency over incandescent lightbulbs. The cost to use a 12-watt LED for 1,000 hours is only $1.32. If you are interested in saving energy and money, consider switching to more energy efficient lighting options.
If you are looking for easier ways to deal with your lights, you may want to upgrade to dimmers, timers, or motion detectors. Dimmers are an affordable option to decrease the amount of wattage and output for your lighting. Timers can be programmed to align with your daily needs. Another option is motion detectors which use heat waves to detect when someone is in the room, and shuts lights off when there is no movement present. These are great solutions to reducing your lighting usage and ultimately saving energy.
