RE: GERMANY SUBSTITUTES WIND FOR NUCLEAR POWER
I hope everyone noticed the contradiction between the two statements,
" Trittin told journalists in Berlin that the wind power plan could see
between 75 and 80 terrawatt hours of electricity annually from
offshore wind parks by 2030. This is equivalent to nearly 60 percent
of the nuclear electricity produced last year in Germany. "
and
" Trittin said that two areas of the North Sea have been identified as
appropriate for the construction of wind turbines which could total
4,000 by 2030. He said that the areas avoid all marine and bird
conservation areas. "
....because 75 to 80 terawatt hours of electricity annually comes to a
steady supply of about 8,790 MWe, which for the typical 25% average capacity
factor of windmills leads to a total installed capacity of some 35,160 giant
windmills, each with 1MWe theoretical capacity -- or about 8.8 times as many
as Trittin claims in the second statement (windmills as large as 1.5 - 2 MWe
have been built, but the 1MWe ones - and smaller - are much more common and
even the former wouldn't make up the factor-of-8.8 difference....).
Furthermore, if these windmills have 50-metre-diameter blades, and they are
spaced at 10 blade diameters by 5 blade diameters, it takes 0.125 square
kilometres per windmill, or 4,395 square kilometres total -- and since
Germany's North Sea and Baltic Sea coasts are only a few hundred kilometres
long, the rows of proposed windmills will be about 10 kilometres deep -- in
other words, the Germans can KISS THEIR COAST LINE GOOD-BYE ! ....any bets
on whether this will actually ever happen ?
.....but its encouraging that at least some folks over there are not blinded
enough to recognise that there are environmental impacts of such "green"
energy :
" Offshore wind power is contentious among Germany environmentalists
who are deeply divided about its environmental impact. The ministry
does not expect its plan to get an easy ride so it has invited
ecologists to a two-day congress this week to debate the
"integration of climate protection, nature protection, marine
protection and energy policy fit for the future."
