THAT: Propane Grill

Propane is very energy-efficient; 90 percent of what gets produced turns into useable fuel. And, according to West’s figures, propane only emits 5.6 pounds of carbon dioxide for an hour’s worth of grilling. When it comes to flavor, a Good Housekeeping taste test performed a while ago found that few people could tell the difference in chicken or hamburgers cooked on gas from those cooked with charcoal (the same couldn’t be said for steaks, though).

Propane is a nonrenewable resource.
