Green Grilling: Gas or Charcoal?

One of the biggest obstacles to going green is having to give up bits of your lifestyle. You know—the convenience factor. (Why do you think Al Gore called it An Inconvenient Truth?) Recycling at home, for instance, is very convenient (when your neighborhood has curbside pickup). But what about recycling on vacation? A hearty "Great job!" to all of you who carry home bags of empties from your campsites; as for the rest of you... we'll continue this discussion later. I'm sure we'll have many more posts about how to make a difference without eschewing all of your favorite things. I'm a big proponent of being as environmentally friendly as possible while still enjoying life the way you want to enjoy it, so join me in the search for that perfect balance!

Today, we're talking about grilling. What is summer without cookouts? But burning stuff on our patios can't be good for the environment, so what's the greenest way to grill? Gas or charcoal? The debate that used to be simply about flavor has evolved into a scientific study weighing the environmental impact of obtaining the fuels, burning the fuels, and disposing of their waste. The electric George Foreman grills would probably win the energy contest, but let's be honest—that's not grilling. I'm talking about charring, smoking, barbecuing.

I shall direct you to yet another Slate article (we do love Slate) on the charcoal vs. gas debate. As the article points out, barbecue emissions account for only 3 ten-thousandths of a percent of the United States' annual carbon footprint, so changing your grilling habits may not matter. But as I will point out, every little bit helps.
.
You'll see there are pros and cons to either fuel. But there is one big rule: No lighter fluid! You don't want to breath its harmful compounds, and you don't want its yucky residue on your food. If you use charcoal (we do, for the true smoky flavor of barbecue), get your coals going in a starter chimney with a couple of crumpled pieces of newspaper.
.
Perhaps more important than which fuel you use is how you use it. If you're using a gas grill, try not to leave it on any longer than necessary. But if you're cooking over charcoal, take advantage of the coals' lasting heat and grill for as long as possible. Why waste all that heat energy by flipping a few burgers and calling it a night? You could get another hour of good grilling out of those coals!
.
When we fire up the grill, we usually have prepared a feast of items to grill in succession, giving us meals for the week. We pile the coals on one side of our rectangular grill so there is a spot for grilling some things over direct heat and a spot for slow-cooking other foods off to the side. One of our latest feasts included burgers, two different kinds of fish, chicken breasts, kabobs, corn on the cob, mixed veggies, potato wedges, onions, and peaches.
.
.
Sometimes we go crazy with marinades and sauces, and it takes three hours to prep everything before we can light the coals, and we end up grilling late into the night. Other times we go for the convenience of bottled sauces, and the prep time simply depends on how long we take to decide which foods we should lay on the grill first. Regardless, it's a fun evening, especially if we're in the mood to try new recipes, and it makes the subsequent weeknight dinners a breeze.
.
.
We do have to add a few more coals to the fire from time to time to keep it at a high, even temperature, but even then we're using fewer coals than we would have if we had grilled each meal on a separate occasion.
.
And, there's always fire left for cooking some dessert. (S'mores, of course.)
