Zero Energy Home produces as much energy as you consume

Geothermal heat pumps have 300-500% efficiency

Why would you still want to live in a substandard quality home that is outdated, unhealthy and wasting a lot of energy?

Majority of houses today have poor insulation qualities, are equipped with run of the mill energy systems and are full of materials that off-gas toxic fumes for years to come. Today's consumers are environmentally aware and in tune with our energy and environmental challenges and demand higher quality of living. How do we get there?
