I totally agree with Lyndon and Elon's recommendation of pricing carbon, which is currently an unpriced negative externality, and a market failure. I wish somebody asked them how to actually make it happen though. I don't need to argue that there is enormous headwind towards gaining a "carbon tax", which to me simply means that carbon polluters have to pay the costs of their pollution. And as long as coal, oil and gas are made artificially cheap because they don't have to bear the costs of pollution, then a clean, sustainable energy future is that much farther away. If the true costs of fossil fuel consumption were shown in the marketplace, then the obvious market reaction would be transition away from them to cleaner, renewable sources.
Not really making a statement here, just an observation. We know the problem. We know the solutions. And we're just not doing it. Just incredibly sad that we're in the process of making the future a whole lot more difficult and dangerous than it really has to be.
