Yes, any shortage of energy we have today is more or less entirely voluntary on a species level.

You can blame Moloch or wall Street or whatever for making it functionally impossible for whatever multipolar market-actor reasons, but with the right choices we could have plenty of energy today, just as we could (but don't) feed everyone on Earth.

Eventually the will bea point where it does actually become physically impossible to generate that much power without melting the Earth's crust or boiling the seas, but that's a long, long way away.
