Easy to sympathise with your point.
We've seen small energy companies that tried to run more nimble disruptive operations go bust, whilst behemoths get bigger. That is a shame. It's a trend across the world in recent years that I do not like.
These companies would say that they're busy driving investment and development into both existing energy sources and also into future renewable sources to meet the UK and wider world's needs and targets etc etc. Challenging landscape in which multiple energy companies have gone bust lately blah blah.

Which yes is slick PR, but it is also true. We do ask and expect these companies to take risks and punt investments that the public sector isn't able. And to do that, they need profits to reinvest.
So the question is what do they do with the profits announced today, how to incentivise more of what we want (reinvestment) and less of what we don't want (excessive bonuses and dividends to execs and shareholders). Perhaps through tax carrots and sticks, perhaps through regulation (and there's topical questions over Ofgem currently).
Also worth considering if you have a pension, it's almost certainly invested in Centrica and Shell. Many of us on this messageboard are likely to be tiny shareholders of sorts in these companies.
