Energy is a general physical and chemical concept and does not reduce to any one issue or set of issues.
energy isn't simpleThe food energy digestible by humans differs from animal feed? used by domestic animal?s, and these differ again from heat?, electricity and mechanical energy? (sometimes from electricity and sometimes to move heat, e.g. in ground source heat?. The energy transfer? from one type of energy to another always results in significant losses, and so there is no such thing as one "energy supply".
[+] energy can ONLY be calculated relative to an infrastructure from perspective of ultimate consumer
the hardest problems: transfer, transportThe political use cannot be separated from formal physical and chemical definitions. When making decisions, the energy transfer? including energy transport? functions tend to dominate any model. It cannot be reliably said to make sense to extract energy in one place and move it to another, beyond a certain distance, which might be extremely short. To localize energy consumption is thus high priority in any effort to conserve energy?. In other words, energy locality defines conservation, and energy transport is an open-ended problem including a vast array of other problems including human health, e.g. see the Tar Sands issue.
[+] energy can ONLY be "saved" by creativity
energy and equity (Illich)Ivan Illich?, in Energy and Equity?, made an irrefutable argument that control over the deployment of human-controlled energy was, in its food, animal and mechanical forms, tautologically defined as power: that lack of ability to direct energy was lack of power in both sociological and mechanical senses. Accordingly, equity? would determine energy access, and energy access would determine equity, and failures of either would necessarily create a vicious cycle?.
Openpolitics.ca itself makes some assumptions with reference to common infrastructural capital - the power grid?, means to refine oil?, transport oil?, transport gas?, and the vehicle?s and furnace?s and generator?s involved. Within these assumptions, it is possible to frame issue?s:
energy demand - which leads to energy conservation?|
power sourcesfossil fuel?s
power useselectricity, e.g. to run computer?s mechanical energy?, e.g. to turn wheel?s
