Do you want to know why so many of these initiatives fall apart? Because they get sold as pipe dreams. We'll just throw solar cells on every roof (what I was actually replying to) and free energy for all! Yeah! We'll power the entire planet! Disagree with me? Screw you, you are just working for big oil!
No. We need to be realistic. In some regions, solar is the bomb diggety. In others, wind can generate a lot of watts. And pretty much anywhere that has hydro or geothermal as an option do great. And in a subset of those, it is sufficient to handle power needs.
So sell it that way. Don't perpetuate the myth that we are "just about there" because that makes it an easy target. Explain that it is still mostly about supplementing power and lessening dependencies. Because pushing the former just leads to "Your proposal will handle about a quarter of non-peak energy usage. And it will take at least a decade until it might get to 50?"

Also, you may want to consider reading other branches as most of your points (aside from the accusations of astroturfing...) were already brought up in other branches. And you'll see that I even praise the UK.
