If the state wasn't being lobbied by the oil and gas industry we'd probably be able to actually invest in nuclear or solar, you're trying to make it seem like the core issues wouldn't be affected by private versus public running it, but conservative politics are what got us into this shit show with removing all economic stopping blocks to the private sector so if we removed the job of energy production from the private sector then we would naturally be able to fix the issue of running the planet into the ground by the very nature of why it's occurring in the first place.
Big oil only exists because 1. It's profitable, and 2. Republicans hate anything that doesn't directly make them and their friends money. They display zero long term thinking because they're a bunch of religious fascists who believe that because THEY think the world is going to end "any day now" we should have to adopt their "fuck the world cause it doesn't matter" mentality.
