Yes it is, that's why it would be supplemental solar. If we added solar capacity to every home, even though it is less than efficient than a large central collector system, The result would still be a low-cost dramatic reduction in the amount of energy production required.

There is not going to be one solution to getting off of carbon. Nested power generation methodologies will be a significant part of our future.

That's really about the only thing I learned in the army. Luckily not the hard way.
