Install a programmable thermostat to keep your house comfortably warm in the winter and comfortably cool in the summer.
Use compact fluorescent light bulbs with the ENERGY STAR ® label.
Air dry dishes instead of using your dishwasher's drying cycle.
Turn off your computer and monitor when not in use.
Plug home electronics, such as TVs and DVD players, into power strips; turn the power strips off when the equipment is not in use (TVs and DVDs in standby mode still use several watts of power).
Lower the thermostat on your hot water heater to 120°F.
Take short showers instead of baths.
Wash only full loads of dishes and clothes.
Look for the ENERGY STAR label on home appliances and products. ENERGY STAR products meet strict efficiency guidelines set by the U.S. Department of Energy and the Environmental Protection Agency.
Check for open fireplace dampers.
Make sure your appliances and heating and cooling systems are properly maintained. Check your owner's manuals for the recommended maintenance.
Study your family's lighting needs and use patterns, paying special attention to high-use areas such as the living room, kitchen, and outside lighting. Look for ways to use lighting controls—like occupancy sensors, dimmers, or timers—to reduce lighting energy use, and replace standard (incandescent) light bulbs and fixtures with compact or standard fluorescent lamps.
Indoor Lighting Tips
• Be sure to buy ENERGY STAR qualified CFLs.
- They will save you about $30 or more in electricity costs over each bulb's lifetime.
- Producing about 75% less heat, they are safer to operate and can cut home cooling costs.
- Visit www.energystar.gov to find the right light bulbs for your fixtures. They are available in sizes and shapes to fit in almost any fixture.
- They provide the greatest savings in fixtures that are on for a long time each day. The best fixtures to use qualified CFLs in are usually found in your family and living rooms, kitchen, dining room, bedrooms, and outdoors.
• Consider purchasing ENERGY STAR qualified fixtures. They are available in many styles including table, desk and floor lamps — and hard-wired options for front porches, dining rooms, bathroom vanity fixtures, and more.
Change your air filter regularly
Check your filter every month, especially during heavy use months (winter and summer). If the filter looks dirty after a month, change it. At a minimum, change the filter every 3 months. A dirty filter will slow down air flow and make the system work harder to keep you warm or cool — wasting energy. A clean filter will also prevent dust and dirt from building up in the system — leading to expensive maintenance and/or early system failure.
Seal your heating and cooling ducts
Ducts that move air to-and-from a forced air furnace, central air conditioner, or heat pump are often big energy wasters. Sealing and insulating ducts can improve the efficiency of your heating and cooling system by as much as 20 percent — and sometimes much more.
Focus first on sealing ducts that run through the attic, crawlspace, unheated basement, or garage. Use duct sealant (mastic) or metal-backed (foil) tape to seal the seams and connections of ducts. After sealing the ducts in those spaces, wrap them in insulation to keep them from getting hot in the summer or cold in the winter. Next, look to seal any other ducts that you can access in the heated or cooled part of the house
Consider installing ENERGY STAR qualified heating and cooling equipment
If your HVAC equipment is more than 10 years old or not keeping your house comfortable, have it evaluated by a professional HVAC contractor. If it is not performing efficiently or needs upgrading, consider replacing it with a unit that has earned the ENERGY STAR. Depending on where you live, replacing your old heating and cooling equipment with ENERGY STAR qualified equipment can cut your annual energy bill by nearly $200. But before you invest in a new HVAC system, make sure that you have addressed the big air leaks in your house and the duct system. Sometimes, these are the real sources of problems rather than your HVAC equipment.
1. Be bright about light
Artificial lighting accounts for 44 percent of the electricity use in office buildings.
> Make it a habit to turn off the lights when you're leaving any room for 15 minutes or more and utilize natural light when you can.
> Make it a policy to buy Energy Star-rated lightbulbs and fixtures , which use at least two-thirds less energy than regular lighting, and install timers or motion sensors that automatically shut off lights when they're not needed.
2. Maximize computer efficiency
Computers in the business sector unnecessarily waste $1 billion worth of electricity a year.
> Make it a habit to turn off your computer—and the power strip it's plugged into—when you leave for the day. Otherwise, you're still burning energy even if you're not burning the midnight oil. (Check with your IT department to make sure the computer doesn't need to be on to run backups or other maintenance.) During the day, setting your computer to go to sleep automatically during short breaks can cut energy use by 70 percent. Remember, screen savers don't save energy.
> Make it a policy to invest in energy-saving computers , monitors , and printers and make sure that old equipment is properly recycled. Look for a recycler that has pledged not to export hazardous e-waste and to follow other safety guidelines. Old computers that still work, and are less than five years old, can be donated to organizations that will refurbish them and find them new homes. (You may even get a tax deduction.)
3. Print smarter
The average U.S. office worker goes through 10,000 sheets of copy paper a year.
> Make it a habit to print on both sides or use the back side of old documents for faxes, scrap paper, or drafts. Avoid color printing and print in draft mode whenever feasible.
> Make it a policy to buy chlorine-free paper with a higher percentage of post-consumer recycled content. Also consider switching to a lighter stock of paper or alternatives made from bamboo, hemp, organic cotton, or kenaf. Recycle toner and ink cartridges and buy remanufactured ones. According to Office Depot, each remanufactured toner cartridge "keeps approximately 2.5 pounds of metal and plastic out of landfills...and conserves about a half gallon of oil."
4. Go paperless when possible
> Make it a habit to think before you print: could this be read or stored online instead? When you receive unwanted catalogs, newsletters, magazines, or junk mail, request to be removed from the mailing list before you recycle the item.
> Make it a policy to post employee manuals and similar materials online, rather than distribute print copies. They're easier to update that way too.
5. Ramp up your recycling
> Make it a habit to recycle everything your company collects. Just about any kind of paper you would encounter in an office, including fax paper, envelopes, and junk mail, can be recycled. So can your old cell phone , PDA, or pager.
> Make it a policy to place recycling bins in accessible, high-traffic areas and provide clear information about what can and can not be recycled.
6. Close the loop
> Make it a policy to purchase office supplies and furniture made from recycled materials.
7. Watch what (and how) you eat
> Make it a habit to bring your own mug and dishware for those meals you eat at the office.
> Make it a policy to provide reusable dishes, silverware, and glasses. Switch to Fair Trade and organic coffee and tea, and buy as much organic and local food as possible for parties and other events. Provide filtered drinking water to reduce bottled-water waste.
8. Rethink your travel
> Make it a habit to take the train, bus, or subway when feasible instead of a rental car when traveling on business. If you have to rent a car, some rental agencies now offer hybrids and other high-mileage vehicles.
> Make it a policy to invest in videoconferencing and other technological solutions that can reduce the amount of employee travel.
9. Reconsider your commute
> Make it a habit to carpool , bike, or take transit to work, and/or telecommute when possible. If you need to drive occasionally, consider joining a car-sharing service like Zipcar and Flexcar instead of owning your own wheels.
> Make it a policy to encourage telecommuting (a nice perk that's also good for the planet!) and make it easy for employees to take alternative modes of transportation by subsidizing commuter checks, offering bike parking, or organizing a carpool board.
10. Create a healthy office environment
> Make it a habit to use nontoxic cleaning products . Brighten up your cubicle with plants, which absorb indoor pollution.
> Make it a policy to buy furniture, carpeting, and paint that are free of volatile organic compounds (VOCs) and won't off-gas toxic chemicals.
