Energy efficiency and renewable energy represent the fastest, cleanest,
and least expensive ways to reduce our electricity use -- and our
dependence on oil. Here, some tips on doing just that, for both
individuals and businesses -- along with links to other resources
that will help you conserve even more.
Individual Actions:
Quick Fixes
Unplug unnecessary electricity-using devices. Are you running a
refrigerator in the basement or garage that contains just a few
items? Unplug it. You may save $20 a month on your utility bill.
Unplug little plastic transformer boxes. Every house is full of
little devices to charge cell phones, run battery-operated radios,
or power television-related equipment. These products consume almost
10 percent of the electricity in the home -- even when they aren't
doing anything. Keep these little boxes unplugged until you need
them. For additional savings, unplug televisions, VCRs, and similar
products when you're not using them. They use significant amounts
of energy even when they are turned off.
Check your computer to make sure it operates in energy saving mode.
Laptop computers save energy by shutting off the hard drive and
blacking out the screen during periods of inactivity. Most desktop
computers have the same feature, but it isn't usually enabled. Set
your computer to "sleep mode," which darkens the screen
when it is not actively used. (Screen savers, in contrast, waste
electricity.)
Turn your computer off when you aren't going to be using it for
a long time. Computers should be turned off if you will be away
from your desk or work station for more than an hour or two (and
less than that if you have not enabled the energy-saving "sleep
mode" features).
In the winter, turn thermostats down to 68 degrees or below. Reduce
settings to 55 degrees before going to sleep or when away for the
day. During the summer, set thermostats to 78 degrees (click here
for a more detailed energy-saving tip.)
Use sunlight wisely. Close shades and blinds during the summer
or when the air conditioner is in use or will be in use later in
the day. During the heating season leave shades and blinds open
during sunny, cold days, but close them at night to reduce the amount
of heat lost through windows.
Simple Low-Cost Investments
Caulk and weather-strip. Don't just seal doors and windows. Look
for other air leaks that you can seal, such as around plumbing penetrations
or ceiling-mounted lighting fixtures.
Buy compact fluorescent lamps. They are now smaller and more attractive
than before; they use a third or a quarter as much energy as an
ordinary light bulb, and last ten times longer. Look for the Energy
Star label, which identifies products that are not only energy-efficient
but also perform better. Replace bulbs that burn a long time first,
such as outdoor porch lights.
Install timers or motion sensors on devices that shouldn't run
all the time.
During the winter, make temporary double-pane windows by using
plastic sheeting over your regular windows. This reduces the amount
of energy lost through your windows.
Investing in Energy Efficiency
When you buy a new appliance or light fixture, choose the most efficient
model possible. Look for the Energy Star label. It tells you the
product uses less energy than standard new products. See http://www.energystar.gov/
for a list of the most efficient products.
Weatherize your home. Increased insulation, leak-free ducts, and
Energy Star windows improve the comfort of your home and reduce
noise as well as saving energy. (Californians can go to http://www.cheers.org/
for information on how an energy rating for your home can tell you
what needs to be done, how much it will cost, and how much it saves.)
If you are buying a new home, look for Energy Star rated homes
or for homes that qualify for utility energy efficiency programs.
When buying a new cooking range, clothes dryer or other heating
appliance, use gas rather than electricity whenever possible. It's
usually more efficient to burn gas where the heat is needed than
to burn it at a power plant, convert the heat to electricity, and
then send the electricity over wires to your house.
Actions For Business:
A typical commercial building uses more energy for lighting than
anything else. The second largest energy user is cooling, and the
third is heating. Electricity use by computers is also important,
but generally smaller.
Quick Fixes
During the winter, turn heating thermostats down to 68 degrees or
below. Reduce settings to 55 degrees at the end of the day. During
the summer, set thermostats to 78 degrees (click here for a more
detailed energy-saving tip.)
Turn off all unnecessary lights, especially in unused offices and
conference rooms and turn down remaining lighting levels where possible.
Many office buildings constructed or remodeled in the last 15 years
have two or three-level lighting controls in the offices. Set the
lighting at reduced output, particularly during the afternoon.
Use a blank screen for the "sleep feature" rather than
a screen saver. Most computers have energy-saving software installed
in them, but the software is not activated. Enable computers' "sleep
mode," which darkens screens when they are not being actively
used. Screen savers do not save energy.
Turn computers off when you leave the office.
Instruct janitors and cleaning staff to turn off lights after they
are finished cleaning in the evening.
Ask employees to turn off lights during lunch hours and when there
is sufficient daylight. Many people still believe the myth that
turning a fluorescent lamp on wastes energy. Actually, fluorescent
lamps should be turned off whenever they are going to be unused
for 5 minutes or more.
Minimize energy use during peak demand hours from 10 or 11:30 a.m.
to 7:00 p.m.
Investments in Energy Efficiency
Buy the most efficient possible appliances, products, and lights.
Look for the Energy Star label, which tells you the product uses
less energy than a standard new product.
If your lighting system uses a large number of incandescent lights
(such as reflector lamps), or if the fluorescent lamps are one and
a half inches in diameter, consider replacing the lighting. Energy
efficient lighting can save 50 percent while providing higher lighting
quality and better color rendition.
Ask an engineer in your company or hire an outside consultant to
look in detail at lighting, heating, ventilating, air conditioning,
and industrial processes to find opportunities for investing in
higher energy efficiency. Most industries and buildings can cut
energy use by 30 percent or more using only measures that payback
all their initial costs in 4 years. Your local utility can often
help in identifying opportunities and may be able to provide financial
assistance for the projects.
When designing a new building, ask your architect how much energy
the building will save compared to your state's Title 24 building
energy standards or ASHRAE 90.1. Often, a good target is 30-50 percent
savings.
