If you intend to use unpredictable sources, such as wind energy, you definitely are going to need a much larger and stronger transmission network to even out the local production variations. For wind energy, be prepared to transfer energy at distances that are similar to the size of a large high or low pressure area. The wind is blowing around the center of the high or low pressure area, but there is no wind in the center.

That is why they are placed in areas where there is a predictable wind pattern, which it happens to be near a large city, most of the time. But my remark was placed a bit further in the future, something more advanced, I am doing research on right now... cannot elaborate...

Perhaps on the trade wind coasts you might a capacity factor CF up to 50 %, in other areas 20-40 %. A 3 MW nominal power turbine with CF=33 % would produce only 24 MWh each day on average.

Right. The coastal areas are the best, but there are some very good inland wind corridors were have been placed. http://www.nrel.gov/wind/systemsintegration/images/home_usmap.jpg http://www.energy.ca.gov/wind/overview.html

I did not comment on content of a book that I did not read. At least, unless the book is no news to me, in which case I don't need to bother for reading it. I commented only on common "anti-nuke" arguments that I have heard plenty of, without reading the above book that you suggested I not comment on in the case that I did not read it. And, how could I comment on a specific book's contents unless I read them or had someone read them to me? Or am I experiencing someone summarizing such or part thereof into "common anti-nuke arguments", and "asking me if I am still beating my wife" by advising me as done above to not comment on contents of a book that I have not read? - Don Klipstein (don(a)misty.com) |
