Control and relevance. These things matter to them as much as profit.

The barrier to entry to produce renewables is lower than fossil fuels - there is no natural oligopoly.

If you own your house, you can put solar on your roof and a battery on your house, and dramatically cut back on your fossil fuel derived energy needs. Communities can do the same, as can utilities and independent businesses.

That's a future where fossil fuel companies are far less relevant. Not irrelevant, but nothing like what they were. That future may be unavoidable, but they are trying to delay its arrival as much as they can. While that may seem like an anathema to many (including me), put yourself in the shoes of a major investor in or executive at a fossil-fuel company, and you might do the same.
