It's easy when nearly all of your population lives in a third of your landmass mostly in the south. We're still talking about residential. Most of our cities and towns are also not walkable if that gives you an estimate of how spread out we are even in urban areas here.

Besides it took laws for power companies to get the last rural communities and families. I remember my grandparents talking about it. Honestly the better investment would be putting up solar panels cut off from the grid with battery banks to cover the most rural over here.
