Fossil fuel and geothermal energy sources for local use in Alaska: Summary of available information

Abstract

FRONT COVER PHOTOS:TOP : From 1922: From to 1962 EXECUTIVE SUMMARYEconomic growth and stability in Alaska hinges partially, if not primarily, on the availability of a mix of affordable and sustainable energy sources. The high and volatile prices of diesel fuel and heating oil have created economic hardship in many areas of Alaska, particularly remote rural communities where these imported fuels are the primary source of energy. Developing local energy sources that are not tied to a global market will help diversify the state's energy portfolio and help facilitate economic growth in many regions. Unfortunately, all areas are not created equal in energy accessibility.The purpose of this report is to summarize existing information concerning locally available, geologically hosted sources of energy across the state. This work considers both geothermal and fossil fuel (oil, natural gas, and coal) resources and is intended to supplement the Alaska Energy Authority's ongoing analysis of non-geologic energy sources such as hydro, wind, and biomass. Collectively, these summaries provide a basis for ensuring that Alaska's entire suite of potential energy sources is considered. Although this review does not represent a comprehensive analysis or resource assessment, the information should assist local, regional, and statewide efforts to reduce the dependence on diesel for heat and electricity.The potential for locally exploitable natural resources varies widely across the state, and certain regions possess more favorable geologic attributes than others. The chapters of this report are subdivided into the 11 regions recognized by the Alaska Energy Authority (AEA, 2009). For each region, discussion is provided on its potential for geologically hosted energy resources including coal, conventional and unconventional oil and gas, and geothermal resources. Many areas of the state lack sufficient geologic information to reliably evaluate local energy potential; summaries of each region conclude with recommendations regarding what additional data or strategies would be most helpful in developing new energy resources for local or regional use.
