This is absurd. The problem of dependence on oil is far more deep seated than the boardrooms of oil companies. I know a bit about this, having worked for one for over 30 years. As far as the major European oil companies are concerned, they are well aware oil is to be phased out and they are not trying to resist it, nor have they for about the last 30 years.
The issue is one of the massive inertia in almost all the technology used by society. You may be right that if the political will had been there we could have got further by now than we have, but it is as plain as the nose on your face that the lack of political will is due to people being unwilling to face the change, not just to lobbying by oil companies. I readily admit that the US oil companies (especially Koch, but also Exxon Mobil) have played an ignoble role in all this by casting doubt on the science until quite recently, but where have the auto companies been and, most of all where has the consumer been? A large proportion of the US electorate and a lot of US politicians continue to pretend that no action is needed.
That is not the oil companies' fault. A lot of Americans are, for ideological reasons, unwilling to countenance any form of action for the collective good. Just look at the arguments about Covid 19. That is your problem, fundamentally. When I was in Houston, I came across people who thought the new tram line being put in was communism!
We will get there: BP thinks we may already be past the peak use of oil. Shell, under Ben van Beurden, has spent the last decade making the big switch to gas from oil (much lower CO2 emissions per kWh) as a stop-gap, since most industrial process and transport uses can use gas with only minor changes in technology. Both companies are investing heavily in renewables. Neither is trying to block progress. But the lead now needs to come from the auto companies. Full marks to Tesla for making electric vehicles sexy. Then there is electricity generation. Here the UK is now already over 25% renewable, Germany and the Scandinavians more, France is largely nuclear. This has come from government action. Next up: domestic heating. We need to get off oil and gas. Government needs to get involved here to tilt the playing field in favour of heat pumps and where practical, solar. No action yet, I'm sorry to say.
So long as Americans elect governments that refuse to do any of this stuff, the problem in the USA will remain. Don't blame the oil companies: vote!
