Insulating a house, he estimated, probably breaks down to 30 percent materials and 70 percent labor — whereas for a solar panel, the materials (which may come from overseas) would absorb a greater percentage of the cost.
His point is that efficiency generates plenty of domestic jobs not only for manufacturing, but also for installation.
