Currently, there are a couple dozen authoritarian regimes, most heavily armed, that are almost entirely funded by fossil fuel exports. That makes me fear things will get worse before they get better.
True; however, this was already the direction things were headed for said regimes as much of the world has begun to focus on energy security. On the upside, perhaps the lowered long-term demand for fossil fuels will reduce the risk of additional resource discoveries leading to more despotic regimes.
