FOSSIL FUEL AND GEOTHERMAL ENERGY SOURCES FOR LOCAL USE IN ALASKA (also known at SP066) is a comprehensive compendium of resources which can be viewed by regional breakouts. Good graphics and well laid out text make it a good research piece. (You can download it at http://www.dggs.alaska.gov/pubs/id/24264). In an unusual way, due to the fact that it is the AK geological survey putting it together, you have a combined report of fossil and renewable sources that can be extracted. It is worth perusing through, if not systematically reading it over time, cover to cover!
