Switch to Natural Gas
If your family loves grilling, buy a grill that can run on your mains gas rather than bottled gas such as propane. Natural gas is the cleanest fossil fuel, and burns more cleanly than propane.
Lower Your Preheat Times
Gas grills are ready to cook in 5 to 10 minutes, whereas charcoal take 15 to 20 minutes. Plan your food accordingly and don’t let you grill burn longer than it has to.
Plan Your Cooking Carefully
Cook the food with the highest cooking temperature when the grill is at its hottest. Put vegetables and fish on the grill earlier and fruit for dessert later.
