America has the technology and resources to meet all its energy needs while safeguarding the earth's climate. The urgent question now is, 'Do we have the will?' At least one city does, and I'm proud to live in it.

An aggressive building performance standard for all new buildings, and a set of performance requirements to be met by all buildings before they can be sold (when upgrades can be included in the new mortgage). These should encompass heating and cooling, lighting, and plug loads. Coupled with new efficiency standards for appliances, lights, and furnaces, this should reduce the energy consumption of new buildings by 50 percent, more or less immediately, and go on from there.
