As buildings are rebuilt, reuse, recycle, and require them to be energy effiecient. Make use of solar and alternative energy. It might cost more up front, but be cost effective in the future. We have a chance to be a front runner for the US in this area like the town in Missouri that totally rebuilt green. Anything that is progressive in conserving energy could be used. The sky is the limit!! We have a chance to show the world our beautiful city.
