Energy costs many times what it did too
Perhaps for the consumer, not for the energy providers
What costs more? Gas or wind? Oil or solar? Coal or wave?
There’s a premium charged for new technology, sure. To cover R&D costs, new tooling, etc, but once the machinery is made, the fuel is essentially free. The wind blows itself, the sun has its own fuel, the tides move freely
Energy arbitrarily costs more because those that sell it have decided it costs more. Aka corporate greed, which is what this post is complaining about in the first.
Does it matter? Ultimately, these are estimates. Educated, data backed estimates, but still estimates.
One larger than expected volcanic eruption, coral reefs dying faster than expected, whatever, all it takes is one or two things to not go the way they’re expected and everything speeds up.
20 years or 25 years, the point is we’re all kinda fucked unless we do something about it.
What we need to do has been and will continue to be debated ad nauseam, but we know we must do something.
