Consider, for example, the problem of wind generation previously
mentioned. Since, as mentioned, even in one of the most advantageous
siting areas for wind, it requires from 2.5X to 4X the needed capacity
to have 50:50 probability the wind farm will provide that much (on a
monthly basis, the multipliers get even larger as time averaging goes
shorter), there has to be that backup generation somewhere, somehow to
make it up when needed. That, unfortunately, means investment in some
other generation capacity that most often now is gas turbine which
drives up demand for diminishing natural gas and does add to the CO.


This is the most bull**** pocket-picking analysis i think i've ever
seen.


Huh? I think he makes a valid point -- facilities must be designed for
peak demand, not average demand.


That analysis uses the accounting of debiting peak load deficits
against a wind generator is intellectually dishonest. The correct way
is to credit a wind generator's output against a conventional plant's
fuel consumption.

One watt-hour provided from wind is one watt-hour not required of coal.

Now, if we really really want to persist in that sort of thinking, one
might imagine a magical future where somehow the impossible happens and
we contravene the laws of thermodynamics by using our wind energy to
excite an energy storing oscillator.

But that's impossible, unfortunately, so we could never imagine B-field
storage (apropos of which results were recently published of a new
apparently b-field-quench resistant (quench-proof?) ceramic
superconductor) , nor Ke storage, nor hydrogen storage nor water
resevoir storage schema for load leveling. oh, wait.

That's why i call it dishonest. Because the limitations of windmill
technology do not require us to build more fossil fuel plants, and
because it's "relatively" trivial to built energy storage systems to
buffer their output, should we deem it helpful to do so.

Hi,
If we talk about energy saving, how about we start driving smaller
vehicles. No monster SUV like Hummer or big gas guzzler V8, V10 engines.
Why we need a Hummer going grocery shopping?
