To reduce the amount of electricity used in our homes:

• Switch to energy-efficient lighting
  Replace the familiar incandescent light bulbs with compact fluorescent bulbs. For each CFL bulb replacement, you’ll lower your energy bill and keep nearly 700 pounds of carbon dioxide out of the air over the bulb’s lifetime. CFL bulbs last much longer and use only a quarter of the energy consumed by conventional bulbs. LED bulbs are also energy-saving, but have a narrower range of application. Advances in LED bulb technology, however, are leading to more applications for these bulbs in the home. LEDs are more efficient than CFLs and do not have issues surrounding disposal, as do the CFLs.
• Improve the efficiency of home appliances
  Home appliances vary greatly in terms of energy-efficiency and operating costs. The more energy-efficient an appliance is, the less it costs to run. You can lower your utility bill and help protect the environment.
• Buy energy-efficient appliances when shopping for a new appliance
  Do this especially when shopping for a major appliance such as a refrigerator, dishwasher, or air-conditioner – select the one with the highest energy efficiency rating. By opting for a refrigerator with the Energy Star label — indicating it uses at least 15 percent less energy than the federal requirement — you can reduce carbon dioxide pollution by nearly a ton in total.
• Reduce energy needed for heating
  According to the U.S. Department of Energy, heating and cooling systems in the U.S. emit over a half billion tons of carbon dioxide into the atmosphere each year. Much of the energy used for heating our homes is wasted, and yet the prevention is, in many cases, simple and inexpensive.
• Reduce energy needed for cooling
  Air conditioners alone use up to 1/6th of the electricity in the U.S. and, on hot summer days, consume 43% of the U.S. peak power load. You can reduce much of the need for air conditioning, and enjoy a cost savings benefit, by using ‘passive’ techniques to help cool your home.
