Now that I've got a whole two years of data on our water usage, I decided this is a good moment to start my own conservation thread. And I'll start with water, since that's what I can brag about
Electricity and maybe gas will come in the future.
I've been recording the water meter's state twice a month since November 2008 (actually, now I record every 5 days, but twice a month is good enough resolution) and here is a graph with average daily consumption, in cubic meters (1000 liters, 264 US gallons).
The blue line is average daily water consumption for each half-month, the red and yellow lines are daily consumption for the preceeding half-year and year, respectively. Between 11.2008 and 11.2009 our average was 0.28 m3 per day, while between 11.2009 and 11.2010 it was down to 0.23
The higher consumption in 04-05.2009 was lawn watering, before we got our first rain barrel installed. In we 2010 we got
two more barrels and they took care of garden watering until a long heat wave/drought, hence the spike in 07.2010. The dips were when either the Wife and I or Dad-in-law were gone for 2 weeks at a time. During the last 2 months we used some rainwater for flushing (about one 8-liter bucket every 1-2 days).
