100% renewable right now. it isn't reasonable and wind really doesn't produce enough consistent energy to do that. nuclear power, that would work and there are a lot of environmentalists saying if we're going to solve this problem, we need to look at nuclear. you have natural gas which burns very cleanly. in fact, the united states has reduced its carbon emissions more than any other industrial nation just by using natural gas. there are solutions to this problem. where i get suspicious is when it looks like people are using climate change for political reasons. they don't actually propose a solution. they talk about renewables like it's reality. it's not. there are realistic solutions. if the climate change people were proposing those solutions they would have more credibility. >> sandra: when you look at nancy pelosi's initial reaction
