My Dream Green House

One of the first moves would be to collect the water from bathtubs, showers, and wash machine in some sort of water tank and reuse the water for flushing toilets. I would have the water heated by the sun and saved in a water tank for showers, dishwashing and washing clothes. Toilets, garbage disposal, and slop sink would empty into the regular sewer system but all the other water would be used twice before going to the city sewer system. Rainwater would be collected from the roof of all buildings on the property and stored in a cistern and used for lawn and garden.
The next big move would be to generate electricity by using either the sun or using the wind. I would light the entire house via this source of electricity. I would have the house wire with commercial electricity for all appliances and one tiny night light in each room in case one has no sun or wind for a long period of time..
The house would be heated by the Sun as much as is possible. Electricity would be the source of alternate or additional heat during winter months. A fireplace would be available to help out with heat and keep the yard cleaned up of branches.
The house would be well insulated. Fans would be part of the lighting system and each room would have a fan. One big fan would be used above the stairwell to pull hot air out. Central air would be used but only used when really needed. A small air lock would be used to cut down on cold air entering the house. Fresh air would come into the house thru the air conditioning system.
I realize that the cost of this house is stiff at the building stage but I do think one could live much cheaper and make up the difference in time. My goal is to be as green as possible and yet keep it a reasonable and comfortable house.
