Summertime and the grilling is easy… but how environmentally friendly is it? We sent reporter Jennifer Guerra to find out which type of grill is greener: gas or charcoal:

Neal Fisher thinks he’s an environmentally friendly kind of guy. He and his wife recycle, they use compact fluorescent light bulbs in the house, they walk most places and hardly ever use their car.

But when it comes to outdoor grilling… it’s charcoal all the way.

“It may be a little decadent when you’re taking the environment into consideration, but I do it.”

(sound of grilling)

On tonight’s menu, it’s burgers, Jamaican jerk chicken, onions, and asparagus. Everything is grilled on basic, 22 ½ inch Weber kettle.

“Nothing fancy, no frills.”

To get the fire started, Fisher throws about 7 or 8 pounds of hardwood lump charcoal into a chimney starter.

“I don’t use the lighter fluid, I just use the charcoal chimney. I figure if I’m going to be cooking wood, I don’t want to cook a lot of chemicals too. So that’s something. I don’t kid myself that this is at all healthy for the world. I sometimes joke about it, too, well there goes my carbon footprint. Suddenly I’m carbon Sasquatch.”

To find out if Fisher really is a carbon Sasquatch, I called up Eric Johnson in Switzerland.

“Basically the footprint of using charcoal is about 3 times higher than the footprint of gas.”

Johnson just published a study in the journal Environmental Impact Assessment Review. In it, he compared the carbon dioxide emissions – or carbon footprint – of the two most popular types of grills: charcoal and propane gas.

When it comes to straight up carbon emissions – gas grills win hands down. Run your gas grill for an hour; emit 5.6 pounds of carbon dioxide into the air. Use charcoal briquettes for an hour of grilling; emit a whopping 11 pounds of CO2.

Fair enough.

But what if we look at the total carbon cycle of propane gas, a fossil fuel and charcoal, which is a bio fuel?

For that answer, we’ll turn to Bill Currie. He’s a professor in the School of Natural Resources at the University of Michigan.

“You have to think about, can we replace the carbon back in the pool that charcoal came from? Can we replace it biologically over a reasonable period of time? And with charcoal, the answer is yes, we can re-grow those trees.”

That’s because charcoal is made out of wood, which is a renewable energy source. So if charcoal is harvested locally in a sustainable way, the re-grown trees can absorb the CO2 – which makes charcoal essentially carbon neutral. So charcoal made out of wood which is renewable. Propane gas on the other hand is made from oil. Not renewable.

“Fuels that are based on coal, oil, petroleum based fuel, it’s not possible to put that CO2 back where it was biologically in a reasonable amount of time. And that’s the big difference.”

But does any of this really matter? I mean, how important is grilling in the overall environmental scheme of things. Well Currie says it’s definitely not a big-ticket item like, say, the size of your house or the number of cars you have.

“It’s probably a small factor in the whole analysis. But at the same time, we make dozens or hundreds of these choices a day. And if we know that one alternative is better than another, these little things do matter because they add up.”

Especially when you consider that Americans are expected to use more than 60 million grills – both charcoal and gas – on July 4th. That’s the carbon equivalent of 900,000 trees. Now that’s a Carbon Sasquatch.

One of the world’s largest oil companies
was hit with criminal indictments and hundreds of
millions of dollars in fines. Mark Brush has more on
the cases against British Petroleum:


BP settled three different criminal cases brought by the Commodity Futures Trading Commission, the Environmental Protection Agency
and the Department of Justice.


The government found that the company ignored warning signs of a Texas refinery explosion
that killed 15 people. It was found negligent in a pipeline oil spill in Alaska. And BP
settled charges of a propane price fixing scheme. All told, the company with pay 373 million dollars in fines and restitution.


Eric Schaeffer is a former enforcement officer with the EPA. He says there’s a
philosophical divide between the company’s headquarters and it’s managers on the
ground:


“And that split in the company in their personality – that kind of schizophrenia – I hope is
going to go away after this settlement.”


BP apologized for breaking the law and say they will fix the problems.

Point: Safe Oil Drilling in Lakes Is Possible

A Michigan Department of Natural Resources proposal to lease Great Lakes bottomlands for oil and gas development has prompted a lot of discussion regarding the risks and benefits of drilling near the Great Lakes. As Great Lakes Radio Consortium commentator Michael Barratt explains, those resources can be developed now in an environmentally safe manner:

A Michigan Department of Natural Resources proposal to lease Great Lakes bottomlands for oil and gas development has prompted a lot of discussion regarding the risks and benefits of drilling near the Great Lakes. As commentator Michael Barratt reveals, those resources can be developed now in an environmentally safe manner.

People around the Great Lakes have seen quantum jumps in the price of energy within the last few months. Gasoline prices in Michigan for example are approaching $2.00/ gallon, natural gas prices have increased 40-60%, and propane prices have increased markedly.


Since Michigan only produces 4% of its crude oil demand and 30% of its natural gas demand, we need to find ways to both conserve and maintain our energy supply.


The Michigan Department of Natural Resources has proposed to lease land under the Great Lakes for the purpose of drilling wells from onshore locations. The proposed procedures require new wells to be located at least 1,500′ from the shoreline. They also require that sites be screened, and no drilling is to be permitted in dune areas, floodplains, or environmentally sensitive areas.


Additional wells drilled under Great Lakes waters may encounter significant reserves to help Michigan have a secure energy supply. Using a safe and proven technology known as directional drilling, it is possible to reach and produce these reserves with little to no effect on the surrounding areas. There have been 13 wells drilled under Great Lakes waters from onshore locations since 1979. Seven of those wells, which are still producing, have produced 439,000 barrels of oil and more than 17 billion cubic feet of gas. There have been no spills, accidents, or incidents associated with the wells since they have been drilled.


New wells drilled under Great Lakes waters, if drilling is allowed , could produce an additional 90 billion cubic feet of gas, and 2 million barrels of oil; enough to heat more than 1 million homes and fuel 157,500 cars for a year. We now have a window of opportunity to use existing infrastructure associated with the currently producing wells to develop some of the additional reserves under the Great Lakes. Drilling pads, roads, pipelines, and production facilities are in place that can be used to drill new wells under the Great Lakes.


Besides energy security, the people of Michigan benefit from royalties paid to the State of Michigan. That money is put into the Michigan Natural Resources Trust Fund to develop and extend parks, and to purchase wetlands and other environmentally sensitive areas. The seven wells currently producing have contributed more than $16,000,000 to the Fund. Additional wells drilled under the Great Lakes could contribute another $85,000,000-$100,000,000


Let’s develop the State’s Bottomland resources now in a safe and environmentally friendly way to ensure that Great Lakes waters and shorelines can be enjoyed by future generations and also to make sure we have the energy supplies here to maintain our quality of life.

Counterpoint: Drilling Not Worth Risk

As the debate on a national energy policy intensifies, the hunt for more places to drill and dig for new energy is escalating. States are now turning their attention to prospecting in one place that hits close to home: the Great Lakes. As Great Lakes Radio Consortium commentator Cameron Davis of the Lake Michigan Federation explains, drilling under the continent’s largest body of fresh surface water is not something to be taken lightly:

As the debate on a national energy policy intensifies, the hunt for more places to drill and dig for new energy is escalating. States are now focusing their attention on prospecting for one place that hits close to home: the Great Lakes. As commentator Cameron Davis of the Lake Michigan Federation explains, drilling under the continent’s largest body of fresh surface water is not something to be taken lightly.


No matter which estimate you believe – that there’s only enough oil and gas to power a Great Lakes state for 2 minutes or 8 weeks – opening the Great Lakes to new oil and gas drilling is simply not worth the risk. Hydrogen sulfide, known to exist in lakebed oil and gas reserves, can escape during drilling causing far-reaching human health problems. Wellhead and pipeline leaks can contaminate groundwater and surface water in streams, often without adequate cleanups by the state agency responsible for drilling oversight. And, drilling can damage some of the most fragile fish and wildlife habitat known, habitat that exists along Great Lakes coasts.


The argument that drilling means more royalties to states doesn’t even hold up. One state Auditor General recently found that oversight of leasing and royalty payments from drilling operations continues to be lax. What does this mean? It means that taxpayers aren’t getting the financial benefits from drilling that they’re supposed to get.


Last, it’s not unusual for the same state agency to serve as subjective promoter of drilling while at the same time supposing to be the objective regulator. States such as Michigan, which is leading the charge for new drilling, can’t have it both ways and maintain their credibility. If they try to have it both ways, it’s inevitable that Congress will step in – as it did this summer with its own legislation.


President Bush, legislative leaders from both sides of the aisle, and a majority of citizens have all said that Great Lakes oil and gas drilling isn’t worth the risk. So why does a bad idea keep moving forward?
