Case studies from nations that have made choices to tap local energy resources: Brazil for sugar cane, Denmark for wind, Spain and Morocco for sunshine, and China with "all of the above," including clean coal and carbon sequestration... and a question as to whether America has made smart decisions for its own national energy policies.
