Dirt on the Coal Supply

Presidential candidates John McCain
and Barack Obama are trying to sell us on a
clean energy future. And they’ve got a laundry
list of ideas, including conservation, solar
and wind power, and safer nuclear energy.
But they both want to tweak an old reliable
fuel, too. That would be American coal.
Shawn Allee looks at why McCain
and Obama are gung-ho on coal:

One reason McCain and Obama tout coal is they’re convinced we have plenty of it.

And they even agree on how to make that point.

McCain first.

McCain: “Our coal reserves are larger than Saudi Arabia’s supply of oil.”

Obama: “We’re the Saudi Arabia of coal, we got more coal than just about
everybody else.”

The Saudi Arabia of Coal.

That’s a sexy political metaphor – it sounds like coal’s just waiting to be scooped up.

Where do politicians get this idea?

“It is really based on data published by the Energy Information Administration.”

That’s Mike Mellish. He crunches coal projection numbers for that agency.

Politicians cite a government figure that we have 250 years worth of coal.

Mellish calls that a very rough estimate. Mellish says we get that number by estimating
how much coal we can get out of the ground economically.

Then, analysts compare that to how much we burn in factories and power plants right
now.

“So that’s really the basis of that statement of 250 years.”

Mellish says, if we use more coal, we’d literally burn through the supply faster.

There are critics who pounce on the idea we have plenty of coal. One of them’s Richard
Heinberg.

Heinberg studies energy for the Post-Carbon Institute, a green think tank. He says
politicians should not expect cheap coal for centuries.

“It assumes we can continue extracting this stuff out of the ground at constant rates
until, one day, it all just runs out.”

Heinberg says America does have lots of coal, but the amount under the ground isn’t the
only thing that counts.

“We tend to get the cheap, easy stuff first, then the production peaks and tails off
afterward.”

Heinberg predicts companies will have to invest money to keep finding new coal, and
that will raise coal prices – not in centuries – but in a few decades.

And Heinbergs says there’s another reason Obama and McCain shouldn’t have so much
faith in coal.

Coal plants put loads of carbon dioxide into the atmosphere, and that makes the global
warming problem worse.

Both candidates want new technologies to put coal’s carbon emissions in the ground.

“But there are a lot of questions as to whether this is really going to work. The cost
of capturing all that carbon dioxide and moving it around and burying it will be
enormous and they will add to the cost of electricity we can make with coal.”

For Heinberg all this talk about the Saudi Arabia of coal, and that 250 year figure, it’s all
a big bet – and it could have a high cost if we’re wrong.

“If we’re going on the assumption that there’s plenty of coal out there for many
decades to come at current prices and we build infrastructure accordingly and then
a couple of decades from now, suddenly coal becomes much more expensive and
scarce we will have gotten ourselves in a very difficult place, sort of like we’d done
with oil.”

A lot of energy experts are more upbeat on coal than Heinberg.

They admit it’s not clear how much coal we have, but it’s a heck of a lot, and we know
how to get it.

They say they don’t blame Obama and McCain for giving clean coal a chance. It’s just
that we should have started testing it a decade ago.

Hmm, a decade ago?

Politicians don’t like to say we’ve missed the mark by a decade.

It’s no wonder we haven’t heard that on the campaign trail.
