Although my energy-saving measures have not been in palce for all of this quarter, our electricity bill is already £100 pounds (USD200) cheaper than it was for the same quarter last year, ie about £200 rather than £300.
I'm really hoping that we'll be paying nearer £100 per quarter, ie £400 per year, rather than over £300 per quarter (£1200, $2400 per year) as we did before.
Real tangible benefits of a little energy-wise thinking already!
It will be interesting to see if stopping all this waste heat from my servers' electricity makes our gas bill go up at all to compensate. I suspect that it won't much, so the saving will prove to be real.
