Here is the jewel of Times Square at 4 Times Square -- The Conde Nast Building -- in New York. It was built in 1999 and is called the first green skyscraper. The building has special e-glass and a fuel cell generator for additional power.

That's a cool building, actually.

There is talk of a new solar cell technology that uses silicon "b-b's" embeded between two layers of aluminum foil and laminated between layers of clear plastic. The idea is that it could cover the outside of buldings, especially skyscrapers. I believe it is 10% efficient and significantly cheaper than normal cells. It is said to look like "denim" jeans material and would make for an interesting looking building.

I know there is also a "polimer" based solar cell that is supposed to be really cheap but not nearly as efficient. Both are very flexible.

I do believe that in the next 20 years or so, most, if not all, power will be generated on site, even for private residences.
