Number two, do you agree with those scientists that it is absolutely imperative that we transform our energy system away from fossil fuel to energy efficiency so that we can leave this planet in a way that is healthy and habitable for our kids and future generations?"

The question is, how do we address it in a thoughtful way that doesn't compromise economic growth, that quite frankly doesn't affect our energy affordability."
