The faster we have everyone understand, the faster we can save our planet earth.
If every suitable rooftop in America were covered with PV panels, up to a quarter of America’s electricity could be produced by PV systems (Dutzik et al. 2010). 
What does this translate to: 87% of solar energy is captured by these panels. Cheap, clean and plenty.

So why not for everyone?
⁃ Concentrating Solar Power (CSP)
⁃ CSP plants function via mirrors that focus the suns energy to harness heat that can either be used directly or to generate electricity. This type of technology has been generating power in desert areas of the Western USA for decades.

Don’t forget hydro and wind. Breakeven on cost a little better. Also not so many town aesthetic conflicts we seem to face as wind and hydro are normally not in residential areas. Even solar farms not in conflict with architectural aesthetics face considerable zoning objection. We initially start with water and tank storage back in the 60’s and then switched to air and rock storage. The first fully active commercial solar building I believe we did and it was a library complex in NJ. Back in the 70’s we used to get considerable federal tax credit but when that dried up solar died as the break even for potential customers was over 17 years in most locations. The problem with air and rock storage was the build up of bacteria in the storage. Today we play mostly with solar voltaic. Still the break even to recoup you initial investment except possible in hot water tank or pool heat contribution makes such an investment meek on capital invested unless folks can be convinced their capital has meek return but helps to save the earth. Passive solar for the most part and &”green” design is free and most architects today incorporate this into all their designs, commercial and residential. Over the past 50+ years I did get about an average of four customers a year for active designs but every one interested in good or passive design to save energy , reduce the use of fossil fuels, and attempt to cut pollution of our earth. Good for you for pushing conservation. Grandaddyearl
