I've never owned a dishwasher but using a dishwasher that is a full load saves 5,000 gallons of water as well as 230 hours of your time every year.........Your computer sucks up energy even when it's idle, so program to sleep for 12 hours a day. You'll help extend its workng life too. .........If you turn up the air conditioner 3 degrees, your home will still be pleanty cool use less enegy. Change the filter as recomended and you will save even more. ..........Repair a drip and you'll conserve 5 gallons of water per day, which adds up to more then 1,800 gallons each year. ........You can reduce the emission of greenhouse gases by 800 pounds a year by taking the bus, walking, carpooling, or riding your bike one day a week. You'll also save about 130 gallons of gas a year. ........I do not like the CFLs but they say it does use 70% less energy. They are suppose to last 10 times longer, but I have not found this to be true.
