I thought is was the other way around. Older supplies with a low power<br>
factor use more energy that what is metered and thus charged for.<br>
Newer supplies have power factor correction at the insistence of the<br>
power companies and governments, so you are charged for the real<br>
amount of power that you're using.<br>
