Unless your outlets had substantial voltage drops due to (dangerously
high) resistance and heating, then ***no way*** will you see truly
the effects you claim.

I call troll, but it might be possible if he did such a bad job of rewiring the
outlets that a good portion of them no longer work at all. That could result in
a reduction of power usage.
