Save money and protect the planet!
1. Seal up your house. Air leaks can account for up to 25% of the heat loss in your house every year. Even for a house that's built well. So seal up the drafty windows and ceiling cracks, and you can save a few hundred a year on your utilities.
2. Use smart power strips. Most appliances and electronics still use power when they're completely turned off. You can buy smart power strips that cut off electricity completely whenever your appliances aren't being used.
3. Get a new fridge and air conditioner. If either one is more than five years old, a new one will be so much more efficient that it could pay for itself in three years, just on the energy you'll save.
4. Switch to LED light bulbs. Yeah, they still cost about ten times as much as the old incandescents. But they use less than a quarter of the electricity, and they last for 20 YEARS. For a typical house they'll save you about a hundred each year.
5. Wash all your clothes in cold water. Modern detergents can get clothes just as clean either way. One hot water load uses five times as much energy as the same load washed in cold water. You can save $100 a year by using cold water every time.
6. Get better fuel economy out of your car. If you can't buy a new car, change a few driving habits. Keep your car tuned up . . . drive a little slower on the freeway . . . and quit trying to be the first off the line at every stop light. You could save $500 a year.
7. Eat less beef. Not that anyone expects you to give up beef. But if you ate less, you'd be healthier and you'd save money. And a family of four that gives up half its meat consumption can save three TONS of emissions into the atmosphere annually.
