  • Just wanted to get your attention. :-)

    What I really wanted to say is that whether or not global warming is caused by man, I don't believe that any of these measures to have "green" energy are worth anything. We'd do a lot better to put our efforts into nuclear power, or researching better advances in power than the same old "green" technologies that aren't poised to really solve anything, except maybe guilty consciences. ;)
    • The trouble with nuclear power is that it isn't a renewable resource either.

      At some point, we are fundamentally limited by the total solar radiation hitting the planet.

      These wind power initiatives generate genuine long term results, they do it immediately, they can be developed incrementally with low lead time, have none of the safety issues, use almost no land (since you can continue to use them as farm land in the NZ example), have no waste products whatsoever, don't require any water for steam, and since
      • Another indefinitely renewable resource: geothermal. The drawback is that it’s harder to exploit than wind as it requires digging up the place. On the other hand, it’s not subject to seasonal or meteorological variations. For a great instant introduction read Malcolm Gladwell’s post about it [].

        Of course, the ultimate source of energy would be The Other nuclear power: sustained H fusion. It too is fundamentally more limited on Earth than tapping the solar output, of course, but it’s also so efficient and we have so much easily “minable” fuel here that that wouldn’t be a worry. None of the toxic leakage issues of fission, either. And in the long now, mastering sustainable fusion will be imperative, since there’s plenty of hydrogen but no wind or geothermal power in space.
