> Widespread Bitcoin adoption would require more energy for mining coins than the entire world can currently produce. No. Bitcoin could work exactly the same even without any more hash power, or energy consumption, ever being added. This is because mining is only a competition to produce a block and defines the security of Bitcoin. But it has no bearing on how many transactions the network can process. Any scaling that happens is completely orthogonal.
