21 Years to Net Zero Energy
This rare perspective of 21 years of energy use reminds us that we shouldn’t treat a house as a static object. We can see that the progress of the Parker household toward net zero electricity consumption is hardly smooth, and many of the bumps don’t seem to correspond to particular technological events. Some of the bumps are good: The birth of two kids seemed to raise electricity use. That’s not really a surprise, but we shouldn’t forget this connection. The physical size of homes grows, too; this house increased roughly 25%. Nevertheless, we don’t see much increase in electricity use. Perhaps that’s because Danny was careful in the design and construction of the addition. Major appliances, such as the refrigerator and air conditioner, were replaced twice over the two decades. This is a reminder that efficiency experts should expect to visit each home several times in the path to net zero energy.
Very cool article from Home Energy Pros – and a great story from a family who have gone from using 10,000 kilowatt hours a year to producing more electricity than they can use!
