Last month's energy usage numbers are in (ok...they've been in for awhile and I've forgotten...you busted me) and the results show more good news:
June/July 2010 Usage: 950 kWh / 22 days = 43.18 kWh/d
June/July 2011 Usage: 1,086 kWh/33 days = 32.91 kWh/d
Savings = 23.79%
Pretty good. One thing to note is last month/this month I've been running that dehumidifier a lot (see previous posts) so that usage is abnormally high.
Compared to the "old" townhome, my usage looks like:
June/July 2009 Usage: 794 kWh/33 days = 24.06 kWh + 8 CCF gas (7.5 kWh/d) = 31.61 kWh/d
Difference = 104.1%
So I was 4% higher...but then again, remove the dehumidifier usage and I'd be lower. But even at 4% higher...can I complain? 2005 built vs 1984 built. 1300 sf vs 2600 sf. Yeah...no way!
The July/August bills will be interesting given how hot its been lately (90s). Last year we used 1636 kWh (51.1 kWh/d). With the mid-high 90s now, we've only used a maximum of 40 kWh/d (last Friday when it was 99-100F). This years July/August bill will hold an additional 2-3 weeks of dehumidifier usage too. FYI, I've switched to 3 hrs on/3 hrs off operation. The system is off right now and the humidity is at 50%. Good. So maybe I'll let it run through the week to see where it ends up holding when its off.
