You're right in that we're apolitical
But you're also correct in that we can't cover topics that can be construed in a political context. Our goal is to talk about policy without engaging in politics. Does that make sense? Covering politically hot topics is necessary -- energy, healthcare, government spending, infrastructure, R&D, private vs. public sector, economy -- but we can do so without slinging mud from either side, too.
To answer your question: A more sustainable energy future is possible because it is necessary. It's pretty clear there are a limited amount of resources on this planet, and we need to figure out how to use them more effectively, or we'll run out of them eventually. That's basic math. How much human population can our planet logically sustain? That's a question better directed at the experts working on this topic.
