I refer you some of the possibilites on how to handle the situation.
When things change, we change with them. Or die.
I do hope the factions decide it is good investment to research bioadaptability and pour money on terraforming projects, agroforests, aquaponics, permaculture, biodomes and better battery tech to get the most out of the available energy.
When circumstances change, we either face it as an opportunity to make things differently, or we stick to old ways and face what comes with it.
