ABSTRACT
Conceptually, the need for energy in a speciŸc form drives the energy demand curve and that demand in turn drives a response from a host of activities. Further complicating the response to a demand for energy are the various interests involved in the supply chain and other aspects of modern societies. These include, for example, political interests, environmental issues, market forces, competition, sustainability, conservation, technology constraints, social concerns, Ÿnancial issues, local and international rules/ regulations, etc. The means of providing the energy produced to an end user must also be included in the discussion of energy demand since the type, quality, and quantity of a speciŸc energy reserve is inherently governed by the distribution systems that are available between the point of supply and the end user.
