2. Upgrade old cooling systems. If
you invest in a central air-conditioning unit with
a seasonal energy efficiency ratio (SEER) of 14 or
higher, you could reduce your carbon-dioxide emissions
by more than 1,500 pounds a year. If you use a window
air-conditioning unit in your home, consider replacing
it with a new unit that meets Energy Star qualifications.
That step could reduce carbon-dioxide emissions by
more than 100 pounds a year. Also, remember to clean
the filters in your cooling and heating systems regularly
and to seal any leaks in central air-conditioning
ducts.
3. Buy a programmable thermostat for your
home. They cost between $30 and $100,
but that’s money you’re sure to make
back over the course of a year because your energy
bills will drop. A programmable thermostat allows
you to adjust your home’s temperature on
a predetermined schedule, so you don’t unnecessarily
waste energy when you’re not home or when
you’re sleeping.
4. Don’t drive
so fast. Driving
your vehicle 55 mph instead of 65 mph can improve
your mileage by about 15 percent and reduce emissions
considerably. You’ll also get better mileage
if you avoid quick starts and sudden braking whenever
you can, and if you keep your tires properly inflated
to the maximum recommended pressure.
5. Watch that idle time. Letting
your engine idle for more than 30 seconds will burn
more gasoline than restarting the engine, so turn
the engine off if you expect a lengthy wait. Instead
of idling at a drive-through for several minutes,
park the car and go inside.
6. Map out your errands. Do multiple
errands on the same morning or afternoon and plan
out your trip ahead of time. Consolidate drives to
locations that are close to each other. If possible,
park your car in one spot and walk when you get there.
7. Take a break from driving. Consider
walking, biking, taking a bus or carpooling whenever
feasible. And if you have more than one vehicle,
drive the one with the best gas mileage whenever
you can.
8. Mow your lawn with care.
Lawn mower engines don’t use a tremendous
amount of gasoline, but they create more than their
fair
share of NOx, a main ingredient in smog. You can
avoid emissions altogether by opting for a low-cost
manual reel mower.
9. Do laundry efficiently. Horizontal-axis
(front-loader) washing machines use far less water
and 60 percent less energy than top-loaders. Regardless
of the type of machine you own, save energy and money
by using cold water instead of warm or hot. Run only
full loads when drying clothes, and dry two or more
loads in a row to make use of the heat already in
the dryer.
10. Think about your refrigerator. Don’t
locate this particular appliance in direct sunlight
or next to the stove or dishwasher. Also, unplug
that extra fridge, especially if it’s just
keeping a six-pack cold.
