I think the biggest impediment to widescale solar adoption is legeslative. If you follow hackernews, you'll regularly see articles about places like Florida (and possibly Nevada if memory serves) where solar could easily power homes, but disingenuous legislative instruments and manipulativly worded ballot initiatives are housed to effectively block solar adoption. This is an example of the top result in Google news http://www.miamiherald.com/news/local/news-columns-blogs/fred-grimm/article69905142.html http://www.miamiherald.com/news/local/news-columns-blogs/fre... Not the greatest example I've seen, but again, if you follow HN you've seen variations on this story dozens of times. Lobbyists protect big utilities instead of facilitate solar. It's tragic to think how much further along we could be.
