We love our net zero, super insulated, solar powered house! The extra expense for the solar and weatherization measures added less than 10% to the construction cost, and we estimate that this premium was paid off in about 12 years through vastly reduced operating costs. It is an all-electric, grid-connected house, and the cost of the energy needed to run the home is very modest–mostly connection fees to the local utility. The extra insulation, high quality windows, and lack of noisy appliances make this a very quiet home.
