They call themselves "energy" companies, so where does it matter where that energy comes from?

In that perfect world where once they knew early on that the consumption of their product would lead to an uninhabitable planet for future generations (because that's what we're facing now), couldn't they have pivoted (slowly) towards true renewables and battery technology? They could have been the leaders instead of the culprits, and positioned for greater long term growth and shareholder value, instead of the relatively short term profits of business as usual.

As long as we're writing science fiction that is... But someone somewhere made a choice to bury the science and keep the status quo, either by action or inaction.
