I started collecting electricity usage data in April 2012, and wanted to check how am I doing this year compared to last year. Of course, as of today, only few months overlap (May-August), but still that will give me some idea if all my energy use optimizations have effect.
Again, since I only started collecting data sometime in April 2012 so that month’s data is incomplete, plus September 2013 is not finished yet. The rest of the data, where the 2012 and 2013 data overlap shows a clear improvement, that is no surprise to me as I have undertaken many optimizations. The house runs entirely on electricity, we don’t have gas or central heating.
It feels good to have measurable effect, I will run this sort of analysis in few months when I have complete two years of data collected.
