Sounds like a bug in the Matrix to me. It will probably be fixed in the next release.

I could be very wrong here, but would the conservation of energy, and the fact that eventually all the used energy eventually ends up as heat energy, mean that the only thing these wind mills could do is move heat from the area of the wind farm to the city or where ever the power is used? Perhaps there could be local changes between night and day but those would have to seem to cancel out beyond the transfer to the city. And the city (plus the heat in the electrical lines) would warm up by the exact amount of cooling at the wind farm?

Check a very recent science book. It is defined. It used to not be, the meter was. It got to the point where are ability to accurately measure the speed of light was restrcited by the definition of a meter. So they dumped the standard for the meter, and instead defined the speed of light. The second is already defined by an atom vibration count, so its accurate. Now, if you attempt to "measure" the speed of light, you are actually measureing distance. The meter is now just defineds as the distance light travels in a certain time period.
