It’s fair to say that it’s possible to improve energy efficiency, but it’s also fair to say that improved energy efficiency usually comes at a cost.
It’s the costs that organizations promoting energy efficiency like to ignore.

This article will deal with savings on the use of electricity, as this is a major component of the EPA’s proposed regulations for cutting CO2 emissions(1).

This does not improve efficiency, it reduces the use of electricity … and imposes a lower standard of living on people.
