I am not sure how another economic system will fix this

You answer yourself shortly afterwards

The issue is getting this done politically

Under socialism, since there are no private owners of companies or oil, there is no incentive for them to lobby the policy in their favour. If you want evidence for this, I could pinpoint you to the People's Republic of China manufacturing some 95% of the world's supply of photovoltaic modules (already the cheapest form of energy available to humanity), spearheading electrification with Ultra-High-Voltage electric transmission lines and battery technology and supply, and leading the current generation of nuclear reactors. In contrast, my capitalist homeland of Spain had a "tax to the sun" during the previous decade that destroyed whatever solar industry we had, because in Spain the fossil fuel lobbyists do have the power to dictate policy, as opposed to China's socialist system.
