Cool Your Home Naturally
Turn off indoor sources of heat
Replace lightbulbs. Swap out your incandescent lightbulbs for compact fluorescents (incandescents release 90 percent of their energy as heat).
Give appliances a rest. Turn your dishwasher's dry cycle to air dry, avoid using the oven, and be sure to unplug electronics you're not using (even on standby, they generate heat).
