Solar cells on all our commercial and residential buildings

I saw this news video today and it proposed what I said here some time ago and that is that we should use photovoltaic cells to transform all the exterior surfaces and buildings we can--commercial and residential buildings--to create our solar power.

With this, we could at least shrink the power companies, at minimum, if not, eventually, do away with them completely, to generate our electrical power. More power to us--power to the people.
