My hope is that we're going to see - and I believe it is the case - we're going to see more and more strong progressives running for office. That's my hope. That's my desire.

If we do not get our act together and transform our energy system away from fossil fuel, there is a real question as to the quality of the planet that we are going to be leaving our children and our grandchildren.

The decision is I'm going to do everything I can to fight for the working class of this country, the low-income people against income and wealth inequality, do everything we can about climate change.

It means joining with allies to deploy renewable energy technologies -- both at home and around the world -- to confront the very real and present danger of potentially irreversible climate change.
