Obama wants to build such things as smart electrical grids and high-speed rail lines, which will offer big environmental improvements. Another obvious thing is that large-scale project financing is virtually frozen, so a lot of renewable energy projects are on hold. If the system doesn't get unclogged before the developers run out of cash, they will be cancelled. Money matters, and we are racing against time.

There really wasn't an environmental movement 30 years ago. The Sierra Club national office in 1969 consisted of one full-time volunteer.

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.

By the year 2000, such renewable energy sources could provide 40 percent of the global energy budget; by 2025, humanity could obtain 75 percent of its energy from solar resources.

We shouldn't fuel the future with the polluting methods of the past, ... We have the technology to power our future in ways that don't threaten our health or poison our planet. Let's choose to use it.

The easiest way to make something cool is to get cool people to do it. Part of this might mean the president has to forget tensions with opponents, or people like Arnold Schwarzenegger who has actually been decent with oil issues. Maybe he needs to pull some of the cool people in and make them model the right behaviors.

The more subtle thing is more speculative. The world is well past its long-term carrying capacity for human beings living a European, much less an American, lifestyle predicated on planned obsolescence. International economic growth is largely a matter of accelerated movement of materials from mines and forests to the dump. Instead of saving and buying decent furniture we can pass on to our children, we charge our credit cards for shaped heaps of sawdust and glue that fall apart in less than three or four years.
