Its adherents most often hold true sustainability as a goal or guide, and make lifestyle tradeoffs favoring sustainability where practical.
Although we try to avoid using to much electricity, our house uses a heatpump that uses of our annual usage. Usage is reduced by installing LED lighting and a low usage lifestyle. Not always possible with two children of course.
In 2008 we installed 1400 (8 x 175) Wp solar panels and summer 2009 an extra 2100 (12 x 175) Wp was added for a total of 3500Wp. That produces around 60% of our annual usage.
Update 2010: Change of 6 panels for larger capacity and another installation of 6 panels. A total of 5480Wp is now installed good for 85% for our annual usage.
Update 2013: Added another 12 panels, now 38 in total and will provide for around 105% our annual usage.
