Bitcoin will consume most of the energy in the world,

Let's answer the questions,

hear me out,

For one,

+Bitcoin mining must stay economically rewarding through PoW.

+Energy markets must continue to have inefficiencies or stranded energy sources, incentivizing miners.

+Bitcoin’s decentralization and security model must still depend on computational proof derived from energy expenditure.

+Public perception must accept, or at least tolerate, Bitcoin’s energy consumption as justified by its utility and security.

For the second,

+Significant technological breakthroughs in renewable energy storage or transmission that eliminate energy waste, removing incentives for miners.

+An unexpected shift in Bitcoin’s consensus mechanism away from PoW (though improbable), dramatically reducing energy reliance.

+Global regulatory frameworks placing heavy penalties on energy-intensive mining practices, severely diminishing profitability.

For the third,

+Discovery and mass deployment of extremely cheap, nearly limitless clean energy sources (e.g., fusion), making energy cost trivial.

+A major global event (economic, environmental, or political) drastically shifts public consensus toward either strongly embracing or categorically rejecting energy-intensive industries like Bitcoin mining.

+Massive governmental adoption of Bitcoin as energy infrastructure support, effectively integrating mining into national grid systems and energy policy, transforming Bitcoin mining into a public utility.
