Besides changing lightbulbs, what else can we do to conserve energy at home?

Use sunlight to warm up your house, by opening blinds on sunny days and closing the blinds at night. Also make sure in the winter to cover drafty windows, that way your heater doesn't need to work extra hard. You can also set your thermostat to a lower temperature when you aren't home. If I'm not home I set mine to 65 and then turn it up when I get back. You can also get Energystar appliances. These appliances are marked with the Energy Star because they save electric.
