#1 priority should be grid-tied solar systems on all new construction,homes and businesses alike. The only way to do that is through a government mandate. Like it or not,the world is going all-electric,and soon. We should do it as cleanly as possible.

Hi Perry1961,

I think you forgot the caveat "where it makes sense" :-) In Northern Europe the sun shines weakly and some countries have heavy cloud cover with strong winds. In these cases it might make more sense to go for windmills with solar water heating and an even higher priority might be to install good insulation to reduce energy demands?

But yes, we need government mandate and starting very soon not in several years time.
