Well sure, the entire global warming crisis is a matter of energy. Almost every problem we have today is a matter of energy.

The problem is, at any given point in time a more productive use of energy then carbon sequestration is going to exist, because it is incredibly difficult to pull carbon out of the atmosphere and it would require a project of herculan scales to make a difference in the global climate.

Imagine it's 10 times as hard to carbon out of the atmosphere as it is to put in.

It has taken the entire world economy decades to get to the point that global warming is moving back a couple of degrees.

To offset that with sequestration you're going to need something the size of the entire global economy, and you're going to need to create that while the only possible input is through government programs and sequestration creates next to zero benefit in terms of profit for the people doing it.

It's going to be hilariously difficult, nearly impossible, and you can't wave that away with "it's an energy problem".

It's only ever going to make sense inside of coal smokestacks.
