Monopoly is a terrible thing, till you have it.

We've got to lift our game tremendously. We'll sell our business news and information in print, we'll sell it to anyone who's got a cable system, and we'll sell it on the Web.

We need to push ourselves to make as many reductions as possible in our own energy use first - and that takes time. But we must do this quickly - the climate will not wait for us.
