13 Easy inexpensive ways to go green

Here are some quick, simple and mostly painless ways to reduce the amount of power you use. Many repay your kindness to the Earth with another kind of green.

Still stalling on going green? Procrastinate no longer.
We give you 13 ideas for saving energy around your home that involve little or no installation and barely a bump in your routine. Individually, they cost less than $75. Collectively, they can save hundreds of dollars a year in household energy bills and thousands of pounds of carbon-dioxide emissions.
You have every reason to follow these tips and not a single reason to ignore them. Get cracking, folks.

1. Take a flier on fluorescents. They no longer buzz, flicker or turn faces blue, and they represent one of the brightest ideas yet for cooling down the atmosphere and your electric bill.
Compact fluorescent lights (CFLs) approximate the glow of incandescent bulbs and use 75% less energy. If every U.S. household replaced just one incandescent bulb with a compact fluorescent, the emissions savings would be comparable to taking 3 million cars off the road for a year.
Don't let the price of CFLs -- as much as $7 each -- turn you off. The lights not only last 10 times longer than incandescents but also save up to $60 in electricity per light over their lifetime. Some utility companies subsidize the energy-sparing lights, reducing the tab to $2 or so.
A bright way to cut your power bill
Not every CFL produces a warm, candlelight glow. To achieve that effect, look for one with a Kelvin temperature of 2,600 to 3,000, says Donn Davy, a home-energy consultant in Novato, Calif. Fluorescents that operate at higher temperatures provide hard, white light better suited for task lighting. Most compact fluorescents are spirals or U-shaped tubes, but you can also find them in bulb form. Some of the newer lights adjust to three levels or work with a dimming switch.
Fluorescent lights contain small amounts of mercury. In some communities, you'll need to dispose of them as hazardous waste.

2. Vanquish the vampires. Remember James Thurber's story about the aunt who worried that electricity was leaking out of the wall sockets? She had a point, of sorts. Appliances that include a clock or operate by a remote, as well as chargers, "are all sucking electricity even when you're not using them," says Dale Bryk of the National Resources Defense Council. Of the total energy used to run home electronics, 40% is consumed when the appliances are turned off.
The obvious way to pull the plug on so-called energy vampires is to do just that -- pull the plug. If you don't want to keep rebooting your PC, you can reduce the juice to it by putting both the monitor and the computer itself in sleep mode when they're not in use. Computers operating on snooze control use about 95% less electricity than those running on full power.
To get yours to nod off, go to the control panel, where you will likely see "sleep" or "hibernate." The sleep mode powers down the computer, whereas instructing it to "hibernate" effectively turns the PC off while preserving your applications. Both modes let you resume work where you left off.
If your computer powers down by default, you can adjust how long it waits before going to sleep -- say, from 30 minutes to 15 -- or set the monitor to power down first. Don't bother using a screen saver, which neither preserves your screen nor saves energy.
To get all your devices on the same nap schedule, plug them into the Smart Strip Power Strip ($31 to $44). The strip senses when your computer or TV is asleep and electronically unplugs devices that depend on them, such as a printer or DVD player, until the controlling device wakes up.

3. Harness the wind. Once you've cleaned up your own act, help clean up the power grid by buying so-called green energy -- electricity generated by wind or solar power or a blend of renewable resources. You'll pay about a half-cent to a few cents more per kilowatt-hour for green-powered electricity compared with electricity generated from nonrenewable resources.
If companies in your area haven't yet gone with the wind, you may still be able to pay a small premium on your utility bill to support green power elsewhere. Or you can subsidize it separately, with so-called green tags or renewable-energy certificates.
To find certified renewable-power sources in your state, as well as programs that sell green tags or renewable energy certificates, go to the Environmental Protection Agency's Green Power Locator or to Green-e.

4. Insulate your water heater. The newest electric water heaters have plenty of insulation. But if you have one built before 2004, wrap it in an insulating blanket (under $20) and save 10% -- about $30 -- annually on your water-heating bill.

5. Cover the hot tub. Hot tubs lose heat even with the top on. Float a thermal cover ($26) under the hard cover and cut energy use by one-third.

6. Service the furnace. Have your furnace tuned every two years, and you'll save about 1,250 pounds of carbon dioxide and 10% on your heating bills.

7. Turn down the heat. For every degree you lower your home's temperature during the heating season, subtract 5% from your bill, according to the Alliance to Save Energy. An Energy Star programmable thermostat ($70) saves more than twice its price within a year.

8. Set the washer to cold. Use cold water to wash your clothes and save 50% of the energy you would otherwise use for hot water. Set your dryer on the moisture sensor, not the timer, and cut energy use by 15%.

9. Dim the lights. Install light dimmers, which cut electricity use by the same percentage that they lower the light.

10. Stop drafts. As your father would say, don't heat the great outdoors. Put weatherstrip around the frames of your front and back doors and save about $30 per year in energy costs.

11. Lower your water temperature. Set your water heater at 120 degrees. If your heater does not have a temperature gauge, dial down until the water feels hot, not scalding. (Before going too low, make sure your dishwasher has a booster heater, which gets the temperature back to 140 degrees, necessary for proper cleaning.)

12. Insulate pipes. Wrap precut pipe insulation around exposed hot-water pipes, including pipes traveling through crawl spaces. Your dollars can help make the world a more sustainable place, says MSN Money's Ann Monroe. Strategies range from investing in environment-friendly funds to buying local food.

13. Use timers on lights. Install occupancy sensors or timers on lights in areas you use only occasionally and for exterior lights, which tend to get left on during the day, says Crissy Trask, a green-living consultant in Spokane, Wash. Occupancy sensors start at $20 per switch, light timers at $7. Anyone with basic wiring skills can install them.
How the savings were calculated
Many of these calculations rely on figures provided by Jeffrey Langholz and Kelly Turner in "You Can Prevent Global Warming (and save money!)," updated to reflect an average electricity price per kilowatt-hour of 10.6 cents, the recent national residential average.
