Installing solar panels (even with going up on roofs) is MUCH safer than logging or working in a saw mill. Nursing is very steady work and pays pretty well, too. But even so, there is plenty of logging still going on. Just not where they live, but in other parts of the country. If they would just move, he could keep on working in a saw mill. (And his wife could find a nursing school almost anywhere.)
There actually is a need for a few coal miners: Even if we don't use it for energy, we still make some specialty steels that require it.
