The Coming Energy Turnaround In Germany
An anonymous reader writes "Germany has decided to close all of its nuclear power plants by 2022 and embark on an energy turnaround that focuses on large increases in sustainable energy production. What will it take in terms of investments, and will it mean cost hikes for German consumers? Will it really mean more jobs in the 'green energy' sector? Quoting: 'Total investment over the next decade for such an energy turnaround is estimated to be roughly €200 billion (or almost $290 billion). ... At the moment, more than 20 new coal-fired power plants are being planned or already under construction; together, they would achieve a total output of 10 gigawatts and could, in terms of power supply, replace nuclear power plants that are still operational. But coal-fired power plants do not fit into the concept of the sustainable energy turnaround that the government has put forward.'"
Solar doesn't produce anything at night.
Don't limit yourself to solar panels. They have solar collectors that concentrate energy onto molten salt that never cools. Energy is added during the day but small amounts of heat are used to power turbines throughout the day/night.

Unless/until we can develop some form of industrial scale fusion, any of the base load options (nuclear, gas, coal, oil) are going to be necessary and will come with a serious environmental price tag attached. Solar and wind need to be developed and widely used but absent some miracles in battery technology and/or transmission losses (high temp superconductors) they will have limits.
If Germany wants to use fossil fuels instead of nuclear that is their prerogative but they are simply trading one problem for another one, possibly worse than the original. I don't really understand what they think they will accomplish other than to mollify people who are (reasonably or unreasonably) terrified of nuclear fission.
I agree. This story is such an excellent example of why environmentalism can be so dangerous and *must* be subjected to intense criticism, not adopted automatically "because that's what we should all do, right?".
It plays on people's fears, causes them to act irrationally and in the end can achieve environmentally negative results - as in the case of Germany introducing 20 new coal power-plants - the same that we've been so fighting so many years to get rid off, since they pollute the air and deplete non-renewable resources. (Yeah, my country neighbors with Germany, so I actually care about the resulting pollution.)
Yay! Progress... :(
Like all decisions driven by irrational fears, this is a bad move.
Germany already has some of the highest electricity prices in Europe (22 Cents/kWh versus 12 Cents/kWh in France, for example) and switching to super-expensive solar power and unstable wind turbines will prove to be eye-wateringly expensive, especially since there's very little energy storage capacity (eg. storage basins) and the existing energy transport infrastructure (ie. pylons across the country) is proving to be rather inadequate and has to be upgraded, naturally at huge economic and political cost (read: lots of NIMBY demonstrations).
Germans are very unrealistic about a lot of things (I'm German, BTW), and I think a lot of people are going to come down with a loud thump in this country when they're finally presented with the inevitable sky-high bills for all this energy utopia.
Hard figures: I'm reckoning on electricity prices of around 30 Cents/kWh in 5 years or so.
My 30 cents to the discussion.

Wind gusts do not cause power surges. Modern Turbines and windmills (the ones with the hundred foot long wings) spin at very low RPM. In high winds brakes are applied to keep the speed down because rapid rotation would destroy the windmill.
I just don't understand why people like you bring up a couple weaknesses of renewable energy then walk away like the only answer is non renewable fossil fuels. The real answer is sustainable energy production that uses multiple renewable sources. Base load from geothermal and nuclear, then you handle summer peak air conditioning load with PV and solar thermal, add in some wind for ~10% of base load, maybe some wave power for a few more percent. Some renewable gas generation from waste digestion (sewage or other organic waste), throw in Hydro where it's available and you have a system that's no entirely dependent on a single source of fuel. Not only that but you don't export several hundred billion dollars a year to hostile countries buying dino by-product to burn.
Energy generation is a national defense issue. Burning coal has made fish uneatable due to mercury content. Fossil fuels will run out someday and it is in the national interest to move away from non-renewable sources of energy because in the long run they will run out.
Right, because nobody ever solved the problem of "how to clean a mirror", and plants like SEGS that have been operating for over a quarter century without a significant drop in efficiency, they're just lies and propaganda.
In fact, the *newest* section of SEGS is 21 years old, and still going strong.
This will mean more and more hydrocarbons will have to be used to sustain the German economy. This is a hysterical political response from form uniformed and misguided environmental do gooders. I made an earlier post in another article about thorium reactors. These have no where the dangerous consequences of uranium/plutonium reactors. Thorium reactors have already been built in the US. But the reason why they never went commercial is because you cannot produce nuclear weapons from them in a practical sense.They better hope that fusion becomes viable soon. But I doubt it. People need to be more educated themselves and stop listening to lying politicians and self serving demagogues of fanciful ideologies.
Oh, yeah! Wise guy, huh? Woob woob woob woob! Nyuk! Nyuk!
Except that it's not a level playing field. Fossil fuels get heavily subsidized. According to this, (which I have not independently verified or checked sources on) solar would be cheaper if that was turned around.
At the very least "less optimal economy" seems like disingenuous or stupid way to judge the cost/benefit to me. The costs of global warming, asthma, coal-related deaths, and smog would massively tilt the scale in favor of green. We've let the economists and corporations convince us that fossil fuels' external costs will never ever ever have to be paid off though, just as we let economists and irresponsible politicians convince us that deficits don't matter.
They aren't really dropping nuclear, they are exporting it across the Rhine to France. The analysis I've seen is the only way the Germans keep up with historic demand growth short of tanking their economy is to build more interconnects to France and let the French operate those horrible nuclear plants.
There are 4 boxes to use in the defense of liberty: soap, ballot, jury, ammo. Use in that order. Starting now.
So, Japan got hit by an earthquake and the reactor failed, shit happens, without risk there is no gain...
There's acceptable risks and unacceptable risks. Locating a nuclear plant on a seashore, next to a fault line, is not an acceptable risk, it's downright dumb. We've done the exact same thing here in the USA with a nuclear plant in California that was on the shore and right next to a fault line.
If you're going to do totally stupid stuff like this, you shouldn't be using nuclear power at all. Leave it to someone smarter, like the French, who apparently don't do these idiotic things and have been running tons of nuclear plants safely for decades.
I live in Germany, and I've been following this closely.
First of all, a former government had already decided on a stop on nuclear power, at a much earlier date. The current government reversed that as one of the first major things. It took Fukushima and a huge public outcry for them to reconsider.
So that's the first scam - those who are now hailed as the ones leading Germany into a brighter, greener future had to be forced to walk that path.
The main replacements for the nuclear plants will be coal plants. Which, as everyone familiar with the subject, put out not only more CO2, but also more radiation. Their advantage is that they are less likely to fail catastrophically with nuclear fallout. That's the second scam - energy generation in Germany will actually be a lot less clean and less green.
The choice to go with coal is mostly due to the responsible people clinging to the "baseline" concept, which says you need a certain amount of power stations that output the same amount of electrical energy no matter what the time of day, climate, temperature, season, etc.
That's the third scam, because it is an outdated model. With 21st century technology and systems, the variability of alternative energy sources can be compensated over types or distances and easily create a reliable baseline equivalent. However, those are distributed, decentralized systems, and the technology and business models of big power corporations are designed for large, centralized power stations. They need time to change (if they even want to), and the government has been nice to give them that time. Did anyone yell "campaign contributions"? Please... you have such a bad image of politicians...
Viewed as a whole, the entire thing is a game to stay in power and to find a middle way to please both the corporate sponsors and the voting public. But it has no vision, no conviction and no drive. With the next election, or if public opinion changes, everything will be up for grabs again.
When you read something about politics that mentions a far-future date, always count how many elections are inbetween now and then...

Maybe, but Germans are still trying to find their nuclear waste that East Germany "treated" before the fall of the wall. They do know it is buried somewhere, nobody has a clue where.
