The Pokemon world is based on our world and still uses cars, planes, etc all of which run on both electricity AND fossil fuels. Unless Regieleki is gonna evolve into Regielekiandpetrol it's not going to solve the energy crisis as a whole which was the whole point of SwSh's story.
Furthermore, it'd appear Galar Particles do far more for that than electricity considering Rose's plan was to control Eternatus rather than Regieleki.
Speaking of cars and electronic devices in general, we're also reliant on chemicals such as lithium. Unless Regielekiandpetrol evolves again into Regielekiandpetrolandthemanychemicalsweneedforthingslikebatteries, it's hardly a catch-all solution for solving every single problem in the region.
