"This kind of push from the ground up that we see in Germany is necessary for all countries."

You mentioned Steve that Germany is 'repowering' wind sites. People interested in more can see my piece on repowering in Germany (and elsewhere) in this month's IEEE Spectrum magazine: http://spectrum.ieee.org/jan09/7094. The potential impact is quite staggering.

Go Germany!

It's nice that the US has finally caught up to Germany in GWs of wind, though we have a long way to go in percentage terms. On solar, Germany and Europe can enjoy record low module prices that just emerged this month. See details at:
http://www.setenergy.org

It will be interesting to see how far solar's price will fall in the year ahead...

Onwards,
Dennis

Am I to understand that 7% of Germany's electricity demand is 23,300 Mw of installed capacity? If this is the case their demand is actually 332,800Mw hr
Clarify please.

The article states:

40 terawatt-hours of wind-generated electricity ... makes up about seven percent of Germany's electricity demand.

Thus total German (energy) demand would be about 571 terawatt-hours

The article says that 23,300Mw of installed capacity produces 40 terawatt hrs/yr. This indicates that the average actual output from this 23,300 Mw of installed capacity is 4566Mw which translates into less than 20% efficiency.
To put things in perspective it takes 15,000+ wind turbines that take up goodness knows how many thousands of acres of land that could be producing food and growing trees that both absorb vast amounts of Co2 to produce on average a measly 4566Mw when five 1000Mw Coal,Nuclear or Gas units at the expected efficiency of 90% or better built on about a total of 500 acres or less can produce the same amount of electricity 24hrs /day 365 days per yr.
Little wonder Germany has something like 36 new coal fired units in various stages of construction.I guess they want the lights to come on when they throw the switch.

Does anyone else think that Tony Clark works for the fossil fuel industry??

It is my understanding that coal fired power plants operate at an efficiency of about 30%. Tony Clark fails to mention the coal mines destroy goodness knows how many thousands of acres of land and water systems.

Crops and livestock can operate around wind turbines. How else would a farmer supplement their FARMING income by investing in wind power? Solar PV is attached to the roofs of buildings.

Germany should not be investing in coal fired power plants. Gas is considerably cleaner than both nuclear and coal and would suffice as the country continues its commitment to no more nuclear while making its transition to 100% renewables.

Tony, tell your boss to invest in renewables.

No Daniel - most coal fired plants are base load generators and generate at or close to 100% of their rated capacity. And no, I do not work for the fossil fuel industry - Did I say I was in favor of coal plants?or any other fossil fired plant plant? As for farmers having to supplement their incomes by allowing subsidized wind turbines on their property seems kinda wrong to me ,I would rather just subsidize the farmers who now are cursing while trying to farm around the turbines. You see Daniel, I am a retired farmer,with an education in electrical engineering. I was lucky enough to be able to sell my farm before the wind turbines were erected around my farm.
As for telling my boss to invest in renewables - you will be pleased to hear
that both my boss (wife) and I do -but it sure isn't in wind power.
