OK, you've swapped your old incandescent bulbs for compact fluorescent bulbs. Now what?
The Environmental Protection Agency has five additional ideas, which it is promoting as a yearlong "Change the World: Start with Energy Star" campaign, beginning Earth Day (April 22).
The campaign promotes a six-step program for reducing personal energy consumption in order to reduce electricity demand and thereby reduce greenhouse gas emissions. The government's Energy Star program labels consumer electronic products so that we can make decisions armed with comparative information about the energy use of our purchases.
Generating power is the biggest source of U.S. greenhouse gas emissions, and a big part of electricity demand is the number and efficiency of home electronics.
Replace at least one light with an energy-efficient CFL (that's "compact fluorescent light") bulb or fixture
Use a programmable thermostat and perform regular maintenance of HVAC (that's "heating, ventilation and air conditioning") equipment
Activate power management features on home computers (that is, set your computer to enter low-energy "sleep" modes automatically if inactive for a period of time)
Choose Energy Star-qualified TVs and other home entertainment products
When replacing appliances, choose Energy Star qualified products
Light up for the holidays with decorative lights that have earned the Energy Star
