Germany's oldest remaining nuclear reactor has been shut down, part of a move initiated four years ago to switch off all its nuclear plants by 2022.
Bavaria's environment ministry said Sunday that the Grafenrheinfeld reactor in the southern German state was taken offline as scheduled overnight, the news agency dpa reported. Grafenrheinfeld went into service in 1981. It's the first reactor to close since Germany switched off the oldest eight of its 17 nuclear reactors in 2011, just after Japan's Fukushima disaster. The next to close will be one of two reactors at the Gundremmingen plant in Bavaria, which is set to shut in late 2017. The rest will be closed by the end of 2022.
Germany aims to generate 80 percent of its electricity from renewable sources by 2050.

Probably they just crank up the existing nuclear plants to 11.
They have indeed added coal plants since this announced shutdown. And they appear to only be shutting down the oldest nuke plants. Roughly half their nukes are still running, and they buy a lot of electricity and gas from across borders.
It will take just one nasty spat with Russia in a strong winter for them to realize renewable isn't going to carry the load.
They would need to build out solar a ten to twenty fold to approximate what they get from coal, gas, and nuclear. Germany seems to go to great lengths to propagandize their energy sources making the appearance of making great strides. But its only when you dig just a little bit [cleanenergywire.org] that you find layers upon layers [cleanenergywire.org] of bullshit.
No, you are mistaken. I've always had this sig.

Without further digging, the numbers in the diagrams seem to be for primary energy, which includes residential and other heating. The big bar for "petroleum" is for all the houses that have the tank truck come once a year for their oil heating. The remaining heating is done with natgas, which makes up the larger part of the "gas" bar. There's even trouble going on with gas-fired CCPPs (including a world-leading >60% efficiency one, https://de.wikipedia.org/wiki/Kraftwerk_Irsching [wikipedia.org] ), because the grid doesn't call off enough power from there. It's indeed lignite (brown coal) that supplies most of the fossil based energy.
Germany is also not in need to import any electricity; quite the opposite. The Germans export over 30B kWh/a. http://www.iwr.de/news.php?id=27846 [www.iwr.de] This, for a good part, goes to the French with their dense NPP-population that has to be throttled in Summer when the rivers are too warm. Convenient, when German PV outputs near its peak (> 30 GW) on a sunny summer day.
The Russians have been perfectly reliable suppliers for the last 100 years, except for a short while that had something to do with a little invasion, supposedly (*) to secure Romanian oil sources, and maybe obtain some Kazhak ones, too. This is in contrast to the arabs which brought Germany a car-free-Sunday period in 1973.
So, really, the big piece of the cake is residential heating, which is why the Germans (**) are so obsessed with insulating houses (cf. my post in the bricklaying-robot article).
My NPP stock (which I didn't want to divest of, because of some tax regulation change) took a steep dive not only because they had to shut down a good number of NPPs, but also because it eventually came to be widely known that they had their "savings for dismantling" in the books, but not in the bank (hence the breakup of e.On; RWE might follow suit.).
On top of that comes the discovery that the low-activity waste dump at Asse is rotting away with the junk in mild-steel barrels and the price of fixing this alone will be probably in the dimension needed to kickstart a whole syngas economy. (Mind you, the German subsidies for PV got the current worldwide avalanche rolling). On the topic of this article, the dismantling is particularly interesting, btw, because it resembles the common large 1300 MW PWR widespread in the country in fully irradiated state. AFAIK all previous dismantlings were on less irradiated or smaller plants; they're taking apart a 600 MW PWR at Stade right now (and found out that primary circuit leaks caused the foundation to be contaminated).
(*) Depending on how revisionist someone is, of course :)
(**) except those who celebrate burning US-supplied petroleum just to show the stinkin' treehuggers.

Wrong. Added implies the number went up. We built new coal plants, more efficient ones to replace old ones. Bottom line the number of coal plants is dropping.
And they appear to only be shutting down the oldest nuke plants. Indeed. Actually the article (did you read the summary?) sys so.
It will take just one nasty spat with Russia in a strong winter for them to realize renewable isn't going to carry the load. That is a pretty silly remark as the russian gas in winter is used for heating houses with gas furnaces. How exactly would the house be heated anyway? The amount of gas we use to produce electric power is very low.
They would need to build out solar a ten to twenty fold to approximate what they get from coal, gas, and nuclear.
You are bad in math ... if we increase solar (I assume you mean all renewables) by factor of ten we can power three countries ...

Go back and read the numbers.
You've cherry picked all the easy renewables, already, and you are still only up to 11% of your energy needs. The next best renewables are going to be a lot more costly, because you haven't addressed storage at all.
Like I said. It looks rosy till you start digging through the numbers in great detail. But if you limit your self to the public consumption nonsense you might never know this and will still run around regurgitating the same old nonsense. The figures are available. You just have to dig.
No, you are mistaken. I've always had this sig.

Renewables don't need storage.
That is an american made up myth.
BTW: all renewables together are the biggest power source in germany.

Fossil fuels are renewable too. It just takes a few million years to renew them. ;-)

And then non-renewable again as our sun dies out.
And then renewable again as the universe collapses and a new big bang occurs.
As you go up (or down) the time scale, renewable and non-renewable tend to alternate.

What makes you think the Universe will collapse? Currently the expansion is accelerating and it doesn't look like it will ever collapse, likely ending up in the heat-death of the Universe.
