You can be sure of one thing though, they certainly would buy technology that carries a risk of doing so and leave that one on the shelf.
That requires noticing the technology and understanding it's implications. Also they have limited influence globally - political donors could get solar manufacturing killed off in the USA but that just resulted in the Chinese making a fortune from selling US developed technology to US citizens. The third thing, which I think you dealt with above, is only the sort of oil company run by creationists (yes, selling fossil fuels - weird isn't it) would turn up their nose at making money out of something else. A company near me that started off with coal and natural gas power generation is now making a killing with their windmills. As seen with the extreme of Enron, they are not really in the oil business, they are in the money business and if they can get plenty of money another way they will do it.
