But we haven't done everything we need to do. We need to go further; we need to go faster. Our country's response to our generation's nuclear-free moment, the most important issue facing our future and the future of our kids and grandkids, must reflect the urgency and scale of the emergency. So we've laid the foundations, but next term we need to go further; we need to build on that foundation. We need to erect the walls, and those walls have to be solidly insulated. We need to make sure that when we're building the walls, we're putting inside double- or triple-glazed windows. We need to make sure, when we're putting on the roof, that it's covered in solar panels. And that's what I want to talk about today.
