For me the root of the problem is politics rather than money. Or to be clear, the reasons for procrastinating are not economic. We have the technology to de-carbonize energy and in most cases it's cheaper and better than fossil-based energy production. On the consumption side, the move to electrification is also compelling and in most cases economical - EVs, induction cooking, heat pumps, etc.
But in terms of politics we have Trump paying companies to abandon half-built offshore wind farms and various European countries offering subsidies for fossil-fuel consumption 'to help with affordability' to shield consumers from their dependence on a volatile source of energy.
And that is ignoring the huge and persistent subsidies dished out by governments (estimated at about $800 billion globally - which ignores the externalities like pollution and global warming).
