That's gonna require you to jump through a lot of hoops and it might not even make economical sense at this point in time to build out the grid. It might not ever. You want to cook now, fuel solves that problem.
It's a complicated solution. On top of deployment of renewable energy production, it requires building efuel manufacturing and distribution network. Even if that's doable, it's not something that can be built immediately. And even if built, I don't see how it can compete in impoverished areas with just cutting down whatever is around.
And in the end, it only solves cooking. Electrification solves many more problems at once, and notably refrigeration.
