Energy Usage without the HTPC

Ok...so my HTPC "broke" last week and has been offline.  While I've been trying to troubleshoot the issues (I think I determined its the power supply), I've been able to look really how much energy it consumes.  Below is a figure from Google Powermeter which shows my energy usage before and after the HTPC is shutdown.  I would ignore Saturday and Sunday because there was a power failure at the house which messed up the readings. 

Note the "always on" power usage drops from about 8 kWh to 5 kWh.  This represents 3 kWh of savings or 125W.  That's some signficant savings!  (FYI:  Kudos to my wife who also significantly reduced power usage while I was away on business. I will mention that this is because she spent the majority of her time at her sister's place.  So minimal cooking, no TV, etc.)

So, I'd say that there's a lot of room to fix this.  As I've said in the past, updating my HTPC will significantly help power usage.  Reducing the power consumption down to 40W (which many reviews have shown modern PCs can do) could reduce HTPC power consumption by 68% reducing "always on" power consumption from 8 kWh to 6 kWh (HTPC would consume 0.96 kWh/d).  Yeah, I know someone will mention the two extremes:  "Why don't you not use the HTPC at all and save that energy?!?" or "Who cares?  That only saves you $0.1734/d or $5.27/month".  For the first question...(1) This is my hobby and I'll take the penalty.  And for (2), you're right it isn't a lot...but it's the thought that counts, right?  Plus it feeds the hobby mention in (1).   Oh...and don't forget I've already cut out a lot of the big things to do...so now I'm down to the small stuff anyway.
