I think addiction is the right word. John Spencer, (I think a psychiatrist) compared alcohol dependence, which is a form of addiction, to energy dependence. [Spencer, John: Energy dependence syndrome. Search 1990, 21;8:7-10]

Alcohol Tolerance: The more we drink the more we can drink (within reason).
Energy Tolerance: We have an ever increasing demand for energy consuming equipment.

Take away Alcohol: we develop Withdrawal symptoms.
Take away Energy: we have Social disruption, commercial disorder, personal & domestic inconvenience

Get the alcohol back: Relief and further drinking
Return the energy: Relief when energy supply returns

Alcohol associated with compulsion and craving for more.
Energy: same thing. We have the urge/desire to purchase the new and discard the old manual power

Alcoholism: behavior repertoire is narrowed.
Energy dependence: Human behavior increasingly governed by proximity/availability of supply

Alcoholism: constantly striving to find alcohol
Energy dependence (addiction): Increasing priority to maintain consumption despite consequences

Stop and then restart drinking: relief
Energy: Return to former consumption levels following period of scarcity

-----------------
In humans (and I suppose other animals), addiction refers to a physical dependence and withdrawal leads to physical symptoms. There is no true energy corrolary, but if we consider society as the 'human' in energy addiction, I think that all the nasty events that occur subsequent to energy deprivation would be a good corrolary to the physical dependence seen in addiction.

So, I think addiction is a good word.
