Fun Facts about Saving Energy

A heavy coat of dust on a light bulb can block up to half of the light. Across America, home refrigerators use the electricity of 25 large power plants every year. A hot water faucet that leaks one drop per second can add up to 165 gallons a month. That's more than one person uses in two weeks. An energy-smart clothes washer can save more water in one year than one person drinks in an entire lifetime! |

When you turn on an incandescent light bulb, only 10 percent of the electricity used is turned into light. The other 90 percent is wasted as heat.

A compact fluorescent light bulb uses 75 percent less energy than a regular bulb – and it can last up to four years. A crack as small as 1/16th of an inch around a window frame can let in as much cold air as leaving the window open three inches! Some new refrigerators are so energy-smart they use less electricity than a light bulb! |
An automatic dishwasher uses less hot water than doing dishes by hand - an average of six gallons less, or more than 2,000 gallons per year.

Every time you open the refrigerator door, up to 30 percent of the cold air can escape. Every year, more than $13 billion worth of energy leaks from houses through small holes and cracks. That’s more than $150 per family! Test your energy smarts!Now that you’re learned about saving energy, try this fun online game to test your energy smarts: |
