America would be wise to invest in wind energy as a matter of national defense.

 Gasoline is dense energy. You can haul gasoline to market or to war in a gas-powered tanker truck, but you can’t expect to win a war with electric tanks and jets.

 The cord isn’t long enough for an electric jet fighter, and it kind of gives away the plan if you build a power line to the next area you will attack so you can conveniently recharge your electric tanks and Humvees.   There is only so much fossil fuel, and it should be conserved for use in remote areas where demands for energy cannot reasonably be met by solar, hydrogen, geothermal, biomass, electrical and wind power. The average wind speed worldwide is 12 mph and with current technology and energy prices, wind power is economical at an average windspeed of 14 mph.

Electrical energy from windpower is now economically competitive with electrical energy from natural gas generators. The production tax credit gives the economic incentive to develop better windpower technology now, rather than waiting until we have no choice because we have run out of gas.

    The gearbox failure rate on large turbines limits their reliability over time, according to an IEEE study. Visit some and you will find 30-50% down for repair. Most wind farms have not proven cost effective for return on investment. In this country, wind farms are subsidized by the US government, but owned by foreign companies. Some points to ponder.
