Bioenergy is oil.

When this happens, they're compressed under tons of pressure, and turned into carbon based fossil fuels

If we burn fuels such as coal, oil and gas, they give off various gases.

Geologists scoured America.

As of 2007, coal generates 48.5 of U.S. electricity.

But in the meantime, for the next decade at least, the name of the game is hydrocarbons.

Hands weathered and worn and proud of it.

Will create carbonic acid gas

Coal is a fossil fuel.

Carbon dioxide is a gas that is produced every time a fuel such as coal, oil, or natural gas is burned.

And so far there are only three major sources of that coal and gas, hydro electric, which in most places is maxed out and nuclear.

Here's a piece of coal.

There's some questions as to what you should be doing with this stuff.

It leaves 25 or 30 percent for oil, gas, coal, nuclear, or whatever.

One unit like this is an energy unit of fossil fuel oil, coal or gas.

Coal. Hint of silt.

When that gas blows up, people die.

Coal powered industrial revolution in this country oil, gas, sorry.

This is the story of how Harriet came to pay attention.

Now, what does this have to do with energy?

Coal dust.

More coal doctor.

If they did, we would be shutting down all of our coal and gas plants based on radioactivity alone.

The coal is burning.

Massive coal reserves.

Because if coal turns out to be concentrated plant life, the reason why you may get a differential in gas output between one mine and another the reason why one mine may blow up and another one may not blow up may be because there's stuff eating that stuff and producing gas.

The thread that links them all our addiction to carbon based fuels,

The coal belt in Northern China,

The argument that it's a bridge fuel makes sense, because the amount of CO2 per unit of energy is lower than oil and coal, correct?

Coal consists mostly of carbon.

They substituted coal for oil.

This is regularly several hundred parts per million.

The reason why is because of the radioactive releases from coal.

A crow is as black as coal.

They burned some coal.

But as you think of coal, this is what burned wheat kernels look like.

it's a hot coal.

But I brought along here a lump of coal right here, one lump of coal.

Coal is not always black.

Oil is a problem, and coal is the most serious problem.

(Laughter)

You burn the gas, that radon's being released. Nobody counts that radon against the gas.

The coal in the stove is burning.

The coals are burning red.

Of those, only nuclear and hydro are green.
