This paper from the National Renewable Energy Laboratory plainly states what I've long suspected: the US could be generating practically all of its energy needs with renewable energy technologies, right now.
The question is, why aren't we doing this? The answer, quoted directly from the report, is:
"These are technology-specific estimates of energy generation potential based on renewable resource availability and quality, technical system performance, topographic limitations, environmental, and land-use constraints only. The estimates do not consider (in most cases) economic or market constraints, and therefore do not represent a level of renewable generation that might actually be deployed."
Economic or market constraints. Translated into plain English that becomes "entrenched industries and public perception."
