Indeed: we used to use what you (OP) do now per month and were able one way or another to cut that by ~80% over about the last year or so, without giving anything up.
I hope we can come in at under 2000kWh (ie 2MWh) consumption this calendar year, and it's looking plausible, see: http://www.earth.org.uk/saving-electricity.html
We do solar as well, and hope soon to generate more than we use over the course of the year, but that will never pay itself back from reduced electricity bills: our motivation is carbon-footprint reduction.
Cutting out waste is about 5x to 10x cheaper per kWh than generating with solar PV.
