What Is A Net Zero Energy Home?
Net Zero home is one that’s built to produce as much energy as it uses annually. On a net basis, these homes do not take energy from the system.
A Net Zero Energy building is not necessarily an off-the-grid home. In order to respond to peak demands and periods of lower energy production (such as reduced sunlight in winter, for solar), a Net Zero building may purchase energy from, and sell back to the grid as required.
- The average annual energy consumption for a new home is 39,166 kw/h (141 gigajoules).
- The average annual energy consumption for a net zero home is 10,555 kw/h (38 gigajoules).
Does A Net Zero Energy Home Still Have A Bill?
The answer Yes and No. The consumer, will still need to pay a monthly electric bill, but would still have a monthly electric bill, but they will also be producing and generating their own energy. Annual, they would have spent as much energy as they created. Therefore, the NET cost is still ZERO (depending on energy consumption levels of each dwelling).
The power generated by the consumer will be SOLD to the “grid” and electric companies.
