Which Capital City's in the World are closest to being self-sufficient?

We've often heard that city's, capital ones especially, are the ones that are akin to islands. Always needing constant re-supply with goods every day or so. In addition the distance that the goods have to come in from is often exponentially a lot further than normal too.
With this in mind, where do you think are the most self-sufficient cities in the world for food supply, electricity and spare machine parts...

My thoughts on this are the following 3 city's:

Moscow
Wellington
Rekjavack

No large cities can be completely self sufficient.

Small to medium sized cities are more likely to fit the bill. Large cities need too much shipped in from the countryside in the way of food, fuel and consumables.

I believe Portland, OR in the USA. . . of all places! But not the capital. . .

But as far as the world goes I think Indonesia is on it's way up.

I just moved to Albuquerque, NM and I am an architect so I had to go see the Toas Earthships. Absolutely incredible what these people are doing everything from growing there own food to harvesting water, solar, wind, thermal the works! Check it out. As the city grows so does the technology to improve on these green techniques.
