She’s definitely right about the second part.

These ideas more that pay for themselves in terms of productivity improvements, reduced health care costs, strengthening the economy, etc …

I thought one of the most critical points was in her (excellent) speech:

In my campaign, I have defined the four big goals for our country: restore our leadership in the world, rebuild a strong and prosperous middle class, reform our government and reclaim the future for our children. Meeting the energy and climate change challenge is essential to reaching every one of those. I do not want to be part of the first generation to leave America and the world in worse shape than when we found them. It will not happen on my watch.

This statement places energy/global warming central to her presidency (if elected).
