By "hostile" I mean a market set up such that it's not possible for renewables to meaningfully participate, rather than that people are actively anti-renewables and campaigning against them etc.
I think the US is moving this way, by removing grants for green energy, continuing grants for oil, placing targetted tariffs on solar panel manufacturing countries, and blocking planning permission for wind.
> continuing grants for oil
Oil isn't used for grid energy generation in most parts of the world... We shut down our last diesel plant many years ago. It's way too expensive, relatively speaking. Like, here we're using renewables to power oil extraction lol. For the most part, renewables don't compete with oil since renewables power the grid and oil doesn't. Electric vehicles can reduce oil demand somewhat, but there will still be massive demand for oil for shipping, air travel, construction vehicles and farming vehicles, for the forseeable future.
No one here is against solar panels on their home and few are against wind farms, there's just also the realisation that for many applications, oil will remain for the time being. Aircraft, boats, tractors, and cars in many regions of the world are simply unsuitable for electric power with the current state of electric storage (batteries are heavy relative to energy stored).
