That's interesting as I don't generally follow these things. Do you think the oil companies are controlling the current regime? It does seem to be doing things that favour them such as cutting back on renewables and reducing regulation. As you say, the oil companies want some stability for their long term investments so all this conflict may not be good for business.
I am not a fan of this regime (to put it mildly). I think we need cleaner energy sources and things like domestic solar give people some insulation from the corporations. That said, we will be burning oil for a while yet. We just not be able to burn it all and have a decent planet to live on.
Oil companies are not controlling the current regime, as they don't have any financial benefit.
Any good business prefers consistent policies. I am sure you know that these policies are anything but consistent :)
