1. Lobbying groups for fossils and nuclear trying to find disadvantages of renewables. The most bizarre thing I saw a while ago was arguing strongly for nuclear largely based on the fact that it's more space efficient (saying the importance of that outweighs cost), while completely ignoring the fact that nuclear plants require extensive nofly zones (note theybare not really a problem atm either but would affect how much we can build out nuclear).
2. A strong push for making large scale renewable installations. While it is true that large scale solar is more efficient than smaller scale, I think the prime motivation is that it benefits large operators and investors, not individuals or small communities. Hence the lobby efforts.
In reality just putting solar on most existing warehouses and parking lots would already cover a significant proportion of our electricity use. And others pointed out how solar (and wind) can often be used in dual use environments benifiting both.
