Renewable energy plans agreed in Copenhagen



Renewable energy plans agreed in Copenhagen
The first sign of progress has emerged from the Copenhagen climate change summit with the agreement to build Europe's first offshore windfarm.

Nine countries including the UK gave the green light to the clean energy facility being built in the North and Irish Seas yesterday (December 7th).

Energy and climate change minister Lord Hunt backed the motion in the Energy Council meeting in Brussels along with representatives from Germany, France, Belgium, the Netherlands, Luxembourg, Denmark, Sweden and Ireland.

Lord Hunt said: "Talks begin today in Copenhagen on how we can cut carbon emissions worldwide. A large part of that will be continuing the domestic decarbonisation of our energy supplies by moving to low carbon sources including wind.

"We're already the world leader in offshore wind here in the UK and today's announcements bring new funding and expert direction to grow this vital new industry. They also mean we can work with other countries in the EU to increase our renewable energy supplies."

The new windfarm will help the EU as a whole meet its renewable energy targets for 2020.

Climate change talks in the Danish capital are set to continue until December 18th.

Yes, if we burn enuf fuel to build enuf windfarm, we may "reach our renewable energy targets for 2020"
But what we don't seem to be looking-at is how , much energy was expended to do this !!!
Currently, the figures are that a typical windfarm returns well under One percent p.a. of the energy which went into making it.
Turbine-Alternator devices have an unusual "Economy of Size". The cost of facing any given area of weather, is a necklace-shaped function of (log) physical size, because one T to replace 4 of 1/2 the diameter weighs 8 times as much as any one of the 4, whilst the One A to stand in for the 4 of 1/4 the thro'put, is about half the cost. The cheapest size is, of course, when the T costs about the same as the A. This happens at around 1m diameter. Just under this and the gearbox disappears !
A very good design of "TAD" of at around this size can readily return 5% p.a. of its cost, which is about 50 x that from current (80m high) "technology". There are two other causes of this huge disparity. bertdotwindonatgmaildotcom
