It is obviously in the interest of national economic security to investigate alternative sources of energy before the extraction of existing supplies becomes prohibitively expensive.  This applies to automotive fuels and general domestic energy use in buildings.  This web site investigates a number of potential fuels and their sources, including agricultural solutions (ethanol and biodiesel fuel from crops) and unconventional refining techniques such as coal-to-liquid, oil shale retorting, and tar sand processing.  It also attempts to dispel some of the common but erroneous beliefs and reports related to energy use and consumption. 

Our civilization has increasingly come to rely on energy.   Everything from transportation to commerce to food supply is heavily dependent on the availability of cheap and plentiful energy supplies.  In the past few years, however, many have realized that energy is a finite resource and that the traditional sources of energy - specifically oil and natural gas - are in limited supply and that we need to prepare for the approaching production maxima.  Indeed, in the United States both the proven oil reserves and the annual oil production peaked a couple of decades ago and we now importing more than half our oil.
