Free heat bathes the Mill Creek NetZero Home’s east wall.
October 18 – Dec 15
Net Import: 1995 kWh
Net Export: 391 kWh
Total Production: 572 kWh
Total Consumption (imported + production – export): 2176 kWh
On the production side, we produced about 9.7 kWh/day when our annual expected daily average is 23 kWh/day.
I’m a bit concerned that we consumed such a boat load of electricity over the past two months. We used 37 kWh/day. Most of that is space heating energy. Our annual expected daily average use is 23 kWh/ day.
I still think we’re in the game. The months clustered around the winter solstice will understandably be when we consume the most and produce the least. Last year we pretty much stopped heating on February 12th, so even if we burn up a large deal of our energy budget by then, the good times will have arrived.
Whatever happens, there will be no denying the numbers.
Today’s readings (October 18 readings in parentheses):
