The electricity bill came in this week, my first since October and the first since I tried to simplify my power requirements through a rationalization of the hardware (read Switching hardware and saving energy.

Has it worked?

Strangely, over the course of the three months, despite now using only 3 computers instead of six to do my work, my electricity bill is actually slightly higher than before.

That doesn't quite match up with the 25% reduction in energy costs I was seeing before Christmas, which I based on the electricity meter readings which were at the time down significantly.
