In our experience investing in microgeneration increased our
sensitivity to possibilities for energy saving. Microgeneration has been very successful for us. Our
base measurements were for 2004-5 (the year before the installation of
photovoltaic cells).
Carbon footprint reductions - in the longer term we aim to reduce our household consumption (i.e. electricity use and gas heating) to no more than 1.0 tonnes of CO2 per year (0.5 tonne per person, which is below the international average in 2007).
If we include the microgeneration power, then we have reduced our net electricity consumption by 90%.
