Net Zero is a term that’s been tossed around for a few years. As with all green building concepts in this economy, it is being shelved until the industry picks back up. I think it’s worth studying and implementing once that happens.
The US Department of Energy defines Net Zero as a house that is 60-70% more energy efficient than a model home, and the remaining 30-40% of energy is created with renewables, such as solar, wind, and geothermal, to bring the energy use to zero.
A net zero home can be on-grid (net metered) or off-grid. Earthships are net zero homes. They create all their own power as well as harvest their own water and deal with their own waste products. This is truly net zero, but probably not suitable for the average homeowner.
