If there is a major grid down scenario, cash and bullion are the least of anyone's worries. And would only help those who have it on-hand. But with solar chargers and generators, bitcoin can still be transacted between individuals who hold their keys if needed. But again, that will also be the least worry. No power, no running water, no fuel, no food deliveries, no grocery stores, no heat or A/C, etc.
Additionally, bitcoin has some projects which could actually turn its energy consumption carbon-negative such as using flare gas from oil fields or landfills for mining: https://twitter.com/DSBatten/status/1566735902617276416
Agreed, Bitcoin uses a lot of energy and energy that must constantly exist in order for BTC to have any value. No Power, No Bitcoin.
No power no ATMs. No power no credit cards. No power no going into a bank to withdraw cash.
So then available cash and precious metals will be worth more and electronic dependent technologies go the way of the dinosaur.

Things that have inherent value will never go the way of the dinosaur.
Bitcoin uses somewhere between 50% and 75% renewable energy, and is helping load balancing the grid. It is actually an enabling technology for renewables, helping soak up excess energy production: https://www.cnbc.com/2021/12/04/bitcoin-miners-say-theyre-fixing-texas-electric-grid-ted-cruz-agrees.html
