AT HOME Postpone mowing your lawn or using other equipment with gas-powered engines. Postpone using your boat or other gas-powered recreational vehicles until evening.
Ozone is less likely to form when temperatures drop in the evening.
Use energy-efficient light bulbs and appliances, and turn them off when you're not using them. Keep your thermostat set at 72 degrees or higher in the summer and insulate your home. Run dishwashers and clothes washers only when full. Conserving energy at home can help cut the emissions from power plants. Avoid using lighter fluid when lighting a grill.
