Of course, if one is already using very little energy, then TPTB have very little to gain by eliminating one, do they?

Reducing one's personal energy use might be a good strategy to make oneself a little less vulnerable, on several different levels.

Odds are that the decision will be based on what is produced for the level of consumption. In that case very low consumption and zero contribution, or negative contribution, is probably not going to be a good place to be.
