> I like a home around 2500 to 3000 sq ft.. 4 bed rooms and 2 1/2 baths.. 2 car garage.. with a nice big yard to make into a garden and room for a greenhouse and a studio.. that is my dream..

That is precisely the current "North American" dream. I say North American because Canada is the same. The point I am trying to make is this. We want big homes. That's fine. However, where does all the concrete, lumber, metal and plastic come from? Is the environment affected more by a bigger or a smaller home? Obviously yes. Lumber comes from cutting down the forest. Metal and concrete from open pit mining. Plastics from processing of oil products. To produce all these things e need to run refineries, smelters, factories, power plants, etc. That means carbon dioxide in the atmosphere. Heating, air conditioning, cleaning a bigger home, removing more garbage from a bigger home. All these things mean more environmental impact.

Bernice pointed that in the UK the average home is 800 sq. ft. In the USA it is 2200 sq. ft. One in relation ot the other means about 3 times as much environmental impact for a home in the USA.

So people face two choices. Keep building large homes, or scale back. Since people always want bigger, the USA will continue to consume a lot of energy, until the price of oil is so high that people are forced to consume less. I suspect that in 30 years, it will be impossible for Americans to keep building like they are. We already see signs of that. In many places there is already a crisis in the collapse of home values. Since building bigger homes means that properties are more expensive, the market place is forcing a loss in the sale of those big homes.

The future probably will be such that people will see themselves forced to live in tiny, very expensive apartments. How long before rising house and energy prices forces people to build small, energy efficient homes? Only the rich will be able to afford the 2,200 sq. ft. I already see it here. Little houses worth 500,000 USD. Nobody can afford to buy those homes any more. Hence the short-term price collapse, followed by massive inflation as energy goes up in price.
