  • Jul 14 2011: Clearly the design of the city is critical to its sustainability. Monolithic cities ringed by large coal-burning power stations is probably not what we want but what we will have if there isn't effective design.

    Satellite cities with local infrastructure is probably a better model with multi-modal supply including as much sustainable energy as can be generated in the locale.

    Is it possible to move entirely to rooftop thermal solar and block-level wind if the design is done properly? Can building-level thermal storage replace the need for a base load in such a scenario? If you can design that you can free us from both coal and nuclear. How about it?

      Jul 14 2011: I think you are right to raise integrated design as a key issue. What we have seen is the evolution of cities in the industrial era. What we're looking at now is a 40 year revolution in urban development... Just look at the Chinese commitment to create almost 50 million new low cost city homes in the next 5 years.

      Daunting....! But looked at a different way, if you do find the right collaborations, supported with policy, what's to say that a ground up SIM-city approach to rapid urban development is so far fetched.

      On smaller, distributed generation, of course you'd expect them to play a part. Our view is that modern gas fired power generation alongside that will address real concerns over supply intermittency.

      We also have to innovate in the combined heat and power technologies and district heating to combat the hues energy losses we see today....

        thanks for your reply.

        Gas still ties us to a non-renewable resource. How long will the reserves last at the forecast rates of growth? It's also a carbon emitter. How do you 'green' it?
