    You can only "waste" a non-renewable resource, in that you have diminished the original stock but not received full benefit. For instance, if we extract ten thousand tons of iron ore and "waste" five hundred tons of it in the process, that five hundred tons is gone from the limited deposit we are mining but has given us no benefit.

    Wind energy is renewable and effectively limitless. We do not diminish the stock of wind by harnessing it, the way we diminish the stock of non-renewable resources by using them. Any power that is lost in transmission was free in the first place and its loss does not take away from anything. Thus even quite high losses in transmission are tolerable, so long as enough power gets through to economically justify the cost of the turbines and power lines.

    •  Ever hear of transmission line loss? (0+ / 0-)

      A nominal value for typical transmission line loss due to electrical resistivity in lines and system components might be in the order of 10% in typical in-utility-system distribution.   If you increase the required transmission line distance to generation sources hundreds of miles away, the amount of transmission line energy losses will increase with increasing transmission distance.

      I'd suggest taking a course in thermodynamics and electricity and magnitism before you commit further time and energy to setting national energy policy.

        It was that nothing was burned and hence nothing was wasted.  It was reduced from top efficiency, but no resources (e.g. gas, coal, wood) is gone forever due to the inefficiency.
