While it might sound prestigious and intimidating, net zero energy efficiency is pretty simple to achieve. Just install a few solar panels or even a wind turbine on your property, and use other methods for saving energy. Louvers, air and vapor barriers, ICF construction, and low energy appliances all used in combination will go a long way towards lowering your energy usage. The renewable energy from your solar panels or similar installations will take you the rest of the way, resulting in successful net zero energy efficiency.
