Efficient houses

Here is my lame assed idea for less energy hogish houses.

1: Each house has to have solar panels. You cannot sell a home that has no water. Why should you be able to see a home that has no power? The price to ad a 1kw solar array is about as much as the cost to plumb a house. 4% of the price of a house can get you 1KW of solar power generation. That is enough to significantly impact your electric bill.

2: Do not stop on the outside of the home as far as solar panels. There is no reason why some form of photo voltaic system could not be set up inside the home to capture stray photons and send them back to the grid as electrons.

3: Hydrodynamic turbines should be standard in all residential street mains. These turbines would trun each street into a tiny hydro electric dam.

With a little bit of available technology and some creativity we could make our world much better and save the average Joe a ton of money. Wouldn't we like to save money and the planet?
