Now we’ve got to accelerate the transition away from old, dirtier energy sources. Rather than subsidize the past, we should invest in the future -- especially in communities that rely on fossil fuels. We do them no favor when we don't show them where the trends are going. That’s why I’m going to push to change the way we manage our oil and coal resources, so that they better reflect the costs they impose on taxpayers and our planet. And that way, we put money back into those communities, and put tens of thousands of Americans to work building a 21st century transportation system.

Now, none of this is going to happen overnight. And, yes, there are plenty of entrenched interests who want to protect the status quo. But the jobs we’ll create, the money we’ll save, the planet we’ll preserve -- that is the kind of future our kids and our grandkids deserve. And it's within our grasp. Climate change is just one of many issues where our security is linked to the rest of the world.
