California sets wind+solar record, 38% of US electricity from rooftops, polysilicon efficiency up, more

Estimating rooftop solar technical potential across the US using a combination of GIS-based methods, lidar data, and statistical modeling – 38% of US electricity could come from rooftops and solar power only. There is no longer a sound argument that intermittent energy sources – wind+solar – can’t power the country. An aside, as a commercial sales guy, I’d love to get a hold of these databases of nationwide rooftop viability scans and turn them into a lead database. Gold mine.
