    not bulletproof

    Wind is actually a part of solar power generation, as the sun drives these forces. Back in the late seventies/early 80's, solar companies sprang up everywhere in the wake of the fuel shortage crisis. Most of these companies disappeared or went nowhere
    when the price of oil fell again, gas returned under a dollar. Lots of investors lost money, including me. I would not be least bit surprised to see oil prices drop again, especially if the US takes all the measures being discussed in Washington right now.
    Wind energy is not all that efficient, and requires enormous space and specific conditions to operate so would account for only a small portion of supply. A serious drop in oil price with the advent of nuclear, gas, cafe standards etc., could put it out of commission. It is worth a shot, but it is not bulletproof, irrespective of the hype going on right now. In my humble opinion.

    • What the hell are you talking about?
      The US uses 10^21 joules of energy per year. That's 3x10^10 kw-years. One 100m windmill produces about 1 Megawatt and is continuous duty at most sites.
      Therefore, you can supply all of US needs
      with 3x10^7 Mw windmills.
      The footprint of such a
      windmill is 0.03 (km)^2. That's 30 mills per km^2. So you need 10^6 km^2,
      which is 1000 km x 1000 km,
      about the size of Texas to meet all
      the US energy needs.

      I wish people would start dealing in facts instead of mindless boneheaded opinions and unsubstantiated statements.
