  •  Wasted energy--definitions? (2+ / 0-)

    Is a feathered wind generator "wasting" energy? The power was never captured, but it's gone all the same.

    If the wind turbine uses its power to elevate a weight, or pump hydro, then the energy is gained--even if the process is extremely inefficient.

    There may be measurements that indicate running turbines to energize gravity is counterproductive because of wear and tear on the equipment . . . or . . . but it seems likely that generating any energy is better than missing the opportunity.

    •  Any energy lost to heat or other forms (0+ / 0-)

      of energy that can't be recaptured is wasted energy. So you really want to use the most energy/cost efficient way of storing surplus energy, which differs depending on the intended use. And we're talking about energy storage, not generation, capture or conversion. Obviously you can make a solar panel or turbine efficient only up to the technology's current and physical limits, but you don't want to lose any of that energy unnecessarily, whether in transmission, usage or storage and reconversion.
