Yes, but this is how you get evicted.
Why do you think that would have helped? The landlord cares about the fact that he/she is paying more money because power consumption is high, not about why power consumption is high.
Besides, there's no way it's really free -- it's accounted for in the monthly rent. If you use less power than average, you are probably better off paying for it yourself.
It's somewhat disheartening that you've founded two businesses, yet you're looking to the letter instead of the spirit of the agreement.
