Germany Produces Record-Breaking 5.1 Terawatt Hours of Solar Energy In One Month
oritonic1 writes "Germany is rapidly developing a tradition of shattering its own renewable energy goals and leaving the rest of the world in the dust. This past July was no exception, as the nation produced 5.1 TWh of solar power (PDF), beating not only its own solar production record, but also eclipsing the record 5TWh of wind power produced by German turbines in January. Renewables are doing so well, in fact, that one of Germany's biggest utilities is threatening to migrate to Turkey."
This can't be right, solar doesn't work, Germany is too far north, the lights must go off every night, PV is a stupid technology, nuclear is the only way!!1 How can this be happening, it must be a liberal media lie put out by the scientifically illiterate eco-nazis... it... it just can't...

with cheaper solar panels and more efficient too. I think there will be a point in the future where no house is build without solar panels.
I don't like the greens too much but on days like this I'm happy that they do have as much political influence as they do.
exxon... says... unsustainable...
No matter how much you wanted to do that pun, 2% greater does not count as "eclipsing".
But at what cost?
"...that one of Germany's biggest utilities is threatening to migrate to Turkey."
Don't let the door hit your ass on the way out.
Discussion of technological breakthroughs is meaningless without a discussion of the cost.
We have the technological capacity to build a hotel on the moon and run flights daily. We don't have the means to do it on an even remotely economically reasonable basis.
And in discussing costs, I mean real costs. Subsidies to the renewable energies and penalties/fees to the fossil fuel based energies are distortions to the economic picture and must be excluded for an honest discussion on the topic. Here in California I saw a state sponsored study that attempted to prove that recycling plastic bottles was more economic than treating them as trash. I actually read the study and what I found is that the authors allowed subsidies to be included in the revenues of the recycling agencies and extra fees charged to landfills (and related) to be counted in the costs of the trash side. Naturally if your agenda is recycling and you have regulatory control over the revenues and costs... you're studying your ability to exercise power: not the economics behind an industry.
BundesScheisse?
Just nationalize the plants that are being shut down and keep them running only as long as necessary. Oh wait... Maybe the banks won't like that, and we don't want to offend them.
“He’s not deformed, he’s just drunk!”
..lots and lotts and lotttsss and lotsssss of..
Obviously there are subsidies to encourage buying solar panels. However, whats really burning the utilities is how the pricing is worked out in Germany. The utilities have to pay top tier price for small scale solar power (ie if you have solar panels on your roof, generating an excess). The way the ends up working is that each kilowatt hour your neighbors put into the grid, the more you have to pay to pull power from the grid. More solar power drives the price up.
I don't see how this can last long term. California has a much more common sense approach - equal pricing. The utilities have to pay you back equal to what you would pay.
Most other US states, the utilities can pay you back less than they charge you.
... and in the DRM, bind them.
a single nuclear plant (http://en.wikipedia.org/wiki/Gravelines_Nuclear_Power_Plant) produces 38 Twh or about 7.5 times more than ALL of Germany's solar power! Don't get me wrong, I think renewables are amazing but the numbers look impressive until you compare them to how the world really powers itself...renewables have a LONG way to go.
There has to be something better then renewable energy.
What will happen to all those to big to fail oil and gas
companies when they are only needed for occasional back
up power.
The sky is falling, The sky is falling...........
Perhaps I should RTFA, but looking at the Wikipedia page on Energy_in_Germany, that looks to be about 10% of monthly electricity consumption, (generously, given that it's summer), and less than 2% of total energy consumption.
If humans are mostly water, and beer is mostly water, then humans must be mostly beer.
Can someone translate this to DeLoreans?
They told you the real story here. The solar and wind guys are getting huge government subsidies and tax breaks. Where as the coal and nuclear providers have to pay all sorts of fees, extra taxes, and of course regular taxes.
So guess who is being more profitable?
You can crush any business by doing that. Anything. You could make growing rice in Antarctica viable doing that. Just offer a big enough subsidy for every ton of rice grown there. Boom. Profit.
The question is can the german government sustain these subsidies indefinitely. As in forever. And if/when they stop providing them what will happen to their renewable programs?
I live in California. We've gone through many renewable programs going back to the 1970s. This has been our experience.
First, we give the renewable company a lot of money.
Second, they build their plant.
Third, we give them big tax breaks for subsidies which last for five to ten years.
Fourth, they operate for five to ten years.
Fifth, the subsidies stop.
Sixth, the renewable power company dies almost instantly.
Seventh, the power station is left abandoned in the desert to rot. There isn't even enough money left after to tear it down. Our deserts are littered with these power plants. Dozens of them. Every time one closes we tend to start up another one. And another ruin is in the making.
I want renewable energy. But I want it to be self supporting.
I've decided to stop wasting my time responding to AC trolls/sockpuppets... so if you want a response from me... login.
"In 2006 the plant produced 38.14 TWh". In a full year. The 5.1 TWh of solar power was for a single month.
Renewables still have a long way to go, but it's 12 times better than you think. :)
Does this mean that Godzilla will immigrate to Germany, because they have more power lines to walk through? With 5.1twh of electric power, how can he resist the temptation? How can Japan possibly compete, with their Nuclear plants mostly shut down?
Who would win this election: Andrew Weiner vs Andrew Weiner's weiner.
I can't see Turkey putting out more energy than coal or natural gas. Surely it wouldn't be any cheaper, or cleaner, to burn Turkey than what they are using now.
Having to work for a living is the root of all evil.
Germany uses on the order of 4,000 TWw per year. 5 TWh in the peak solar month... still a long ways to go. Then again, Germany sticks other countrys with over half of its energy needs.
The Forbes article states "Under current regulations, electricity generated by renewable energy resources are given priority access to the grid. As a result, electricity generated by coal and gas-fired plants is only used “to make up for any shortfalls,” according to the AFP."
Does this mean that the nuclear stations have to divert their power when the wind picks up or the sun comes out? I'm certainly no expert, but I thought in the US it is the opposite, so that the wind stations have to go on bypass and the dams/nuclear stations have priority. Or is the Forbes article simply incorrect?
That is the problem. Notice that conventional electricity generation is used when there is not enough green power produced. Storms that would over speed wind power and block most of the solar power happen quite often and could drop green power generation drastically. During those times convention power plants need to be available. If they are not profitable then they will not be available and brownouts and blackouts will occur due to lack of power. The problem with green power is not generation; it is storage so it can be used when needed and not just when produced. Sure there are some technologies available but they are not widely used. More money needs to go into the storage issue.
According to the Fossel Fuel lobby in the UK, solar and wind isn't economical, drives up the cost of electricity and gas and is bad for the environment, the money should be given on the Fossel Fuel companies instead ..

Germany is subsidizing renewable energy production heavily, very heavily. Their top electric producer is now struggling to maintain their business, keep their nuclear and fossil fuel plants profitable so they are threatening to close up shop and leave Germany at the mercy of renewable. Electricity essential to keep a modern economy going and "running out" is simply NOT an option. If you run low on electricity, you have to shut off stuff, because if you don't EVERYTHING will shutdown. Many renewable energy sources are NOT reliable, the sun doesn't always shine and the wind doesn't always blow and chances are one or both will go away when you need it most. (Heck, fossil fueled plants fail, albeit less often than the weather forecast.. )
While renewable energy may sound good, there are some serious problems looming for Germany if they continue down this path too quickly. Eventually, government money can run out and the subsidizing of renewable energy will stop. Then what happens if all the rest of the electric producers are out of business and the sun doesn't shine on a calm day? Down goes the electric grid. Folks are going to find that Germany is back in the horse and buggy days, only nobody kept any horses around just in case. Bringing up the electric grid in a whole country would take times measured in weeks and would surely adversely impact the German economy.
My German friends, tread carefully. Government subsidies never really work out like you think. There is always a down side...
"File to fit, pound to insert, paint to match" - Aircraft Maintenance 101
The US produces %0.11 of our electricity via solar. just over 2 TWh (source [PDF]). We have how much landmass and we don't even come close to Germany's output. Depressing... I'm curious to know what programs Germany has in place to support adoption of solar and wind energy production. Although it would likely never happen, it would be nice if we could replicate some of that here, in the more weather-stable parts of the country. Even better if we could have some decent mass storage solutions to allow solar to really support the whole grid on a larger scale (as opposed to locally).
BOOP!
"Oh, the solar power haters* are going to love this oneâ"a recent study by Germanyâ(TM)s Institute for Future Energy Systems (IZES), conducted on behalf of of the German Solar Industry Association (BSW-Solar), has found that, on average, solar power has reduced the price of electricity 10% in Germany (on the EPEX exchange). It reduces prices up to 40% in the early afternoon, when electricity demand is peaking and electricity typically costs the most. Thereâ(TM)s a visual of that (in German) here:" link

Any mention of solar or any other renewable energy on Slashdot brings out an army of trolls, dolts, nincompoops and people who haven't commented on a story in ages, but suddenly have a pressing need to hold forth on solar energy. People who say, "It takes 7TW just to build a goddamn solar panel!" or, "Solar's no good because it's only 10%, and since coal is 30%, then that means coal is better because clouds!!" as if we'd passed the limits of technology in the 1890's and had better just get used to what we've got. I don't know what motivates people, or what brings them out for these stories, but it's pretty clear that if there is a concerted corporate effort to spread disinformation about energy, it's definitely working.
The same people who will discuss seriously the best type of deep space drive for a manned mission to the Cygnus constellation will aver with absolute certainty that solar energy is just a pie-in-the-sky pipe dream.
If I was a sociologist, I'd study the phenomenon. But that would just depress me.
You are welcome on my lawn.
... in spain they tax us extra for renewable energy, because otherwise it would be "unfair" to the industry...
The chart says that there is 34.558 GW of solar capacity installed. They then show that 19.4Twh of energy was produced in the first seven months. Lets do some math. The longest day in Frankfurt is 16 hours and 23 minutes while the shortest day is 8 hours and 3 minutes. Therefore, on average the sun is up for 12 hours.19400Gwh / 7 months / 30 days / 12 hours = 7.4 Mw produced on average. That is 22% of capacity. That would mean that when the sun is up solar plants are producing, on average, 22% of their installed capacity. What happened to the other 78%?
Lets do the same calculation for wind power. 24200 TWh /7 months/ 30 days / 24 hours = 4.8 Mw. 4.8/30.533 = 16% (wind works after dark so not daylight adjustment). Where is the other 84% of capacity.
http://phys.org/news/2013-08-german-energy-giants-conventional-power.html
Here are the numbers from the chart on page 4:
Electricity production: first seven months 2013
Uranium -- 52.1 TWh
Brown Coal -- 85.1 TWh
Hard Coal -- 65.5 TWh
Gas -- 23.8 TWh
Wind -- 24.2 TWh
Solar -- 19.4 TWh
Run of River -- 10.5 TWh
Total energy production was about 280.6 TWh, renewable was 54.1 TWh (or about 19.3% of all energy production).
Also interesting is the chart on page 9, "Monthly Production Solar". It is a bar graph, so these numbers are mostly my eyeball estimates:
January: 0.35 TWh (exact number)
February: 0.6 TWh (my estimate)
March: 2.3 TWh (my estimate)
April: 3.1 TWh (my estimate)
May: 3.3 TWh (my estimate)
June: 4.3 TWh (my estimate)
July: 5.1 TWh (exact number)
So winter really is bad for solar in Germany, but other months it isn't bad. Interestingly, wind does better in Winter... chart on page 10, "Monthly Production Wind", same deal as above (mostly eyeball estimates with two exact numbers):
January: 5.0 TWh (exact number)
February: 3.2 TWh (my estimate)
March: 4.7 TWh (my estimate)
April: 3.3 TWh (my estimate)
May: 2.8 TWh (my estimate)
June: 3.3 TWh (my estimate)
July: 1.7 TWh (exact number)
It doesn't look like renewables will be able to produce 100% of power needs any time soon in Germany, but they are producing about 1/5 of all energy. More than I expected.
Critics claim that Germany is paying six times as much for power, to finance all the renewables. (Per that article, 18 billion Euros paid on power that has a market value of 3 billion Euros) See also the Wikipedia article on Renewable energy in Germany.
Presumably though this is an investment and the renewables will keep providing power once their costs have been paid fully. I'm wondering if, over the operational lifetime of the solar and wind power equipment, they will wind up producing enough power that they will have actually been a good investment?
IMHO it would make more sense for them to keep the nuclear power plants and try to shut down coal plants, but that's not their plan.
lf(1): it's like ls(1) but sorts filenames by extension, tersely
Since the sky seems to fall quite often, maybe we should build skyfall power plants.
The Tao of math: The numbers you can count are not the real numbers.
OK, so they made a lot of power in one summer month. Show us a graph of their production for a year. I've been to Germany in the summer and the winter (used to work for a German company) and I know what it's really like there. Hope they've got a lot of storage and low demand...
On page 22 of the report it states that 1.32 TWh were produced in calendar week 29. According to page 3 there are 34.558 GW of installed capacity. Lets do some math; 13200/7/16= 11.8. That is 34% of capacity.
Take a look at page 71 of the report. Notice that as solar becomes more prevalent there is more electricity being imported.at dawn and dusk and more surplus exported around noon. What if every country tried to do that? There would be shortages at dawn and dusk and massive surpluses at noon. This is why I say that electricity generation is not the problem; electricity storage is.
I guess that's a great place to put the next PRON video server - fast fiber, plenty of energy.....
The 900 lb gorilla in the room is the shutdown of nuclear generation. This is causing a much faster increase in coal consumption and construction of more coal burning plants in Europe.
A lot of what is being mined and burned is nasty brown stuff too.
The idea is that it's going to be replaced by renewables. Someday maybe, but I bet not in my lifetime. The upshot is that despite all this solar etc. the EU is spewing more CO2 than ever.
The Economist has a great article about it. They call it the 'Golden Age of Coal'.
Solar is "working" thanks to bailouts (oops... subsidies) provided monthly to the producers by the rate/taxpayers. And meanwhile power provided by coal and gas fired power plants has risen 12% in the first half of 2013. (Search "coal power in germany" for all the information you could ever want)
The only thing that is working is a glorious example of rent seeking crony capitalism.
1. Rate payers pay much higher electricity rates
2. More coal plants - more emissions
3. Politicians get to claim "I'm green! Elect me!". Likely earning kickbacks along the way
4. Government guaranteed profits to green energy producers
5. Everybody wins!!
my god, this is AWESOME. the next step will be to use the earth as battery; instead of discharging the earth battery (pumping out oil and coal and gas and "morsche atome") finally someone can recharge mother nature ... assuming this trend continues. it will not be easy ... nobody has even thought about these kinds of technologies ... uplifting natures energy instead of breaking her apart. any ideas?
Yes, and who was the fool that put a nuke plant in a coastal tsunami prone part of the world. The problem isn't nuclear. The problem is the fuel. Uranium style reactors were developed as a kinda afterbirth of the manhattan project. Uranium plants can produce plutonium needed for the bomb. The soviets just took a further approach and made all their reactors, the RBMK series, produce plutonium as a direct byproduct of fission chain reaction. With a high void coefficient and poor management we saw what happens with being careless with nuke plants did in 1986 and the power of location in fukishima. However the gates foundation is funding research into thorium based reactors. Very much safer and if something were to happen, the by products have very short half lives and don't have the bio consequences of Cesium 137 and Strontium 90. Fusion isn't around but probably because it keeps getting defunded. They thought fission was impossible too at one point.
The problem isn't the technology, the problem is the fuel. But then again listening to the far left on energy works all the time. Too bad Solyndra isn't around to sell to Germany. Not that the right is even better. Oh wait... this is slashdot.
Any propaganda coming out of Germany with links to the 'Green' party can be considered dishonest in the extreme.
This is how Germany's actual 'green' policies work. Recently acquired a Bosch tool. The flimsy and near useless instruction manual was made from recycled toilet paper (as per Germany's 'green' laws) and actually near enough dissolves if wet (no exaggeration). In the same packaging were glossy, plastic-coated, near indestructible promotional leaflets for other products from Bosch. Green laws meant that the thing you need to keep and refer to (the instructions) are crap, and the junk advertising literature is as non-environmentally 'friendly' as possible.
The EU, led by Germany, recently placed massive tariffs on cheap solar energy panels from China. Apparently 'green' thinking doesn't spread to encouraging consumers by giving them access to the cheapest 'green' technology possible.
In the UK, fake solar panels are seen in many places- pretending to power decorative lighting, for instance. The fake installations have cost far more than the electricity they PRETEND to save, but that point is moot since the real power still comes from the ordinary electricity grid. The fake panels represent the attempts by councils to hit local 'green' targets.
Here's a clue. Germany is NOT a sunny nation. Here's another clue. The German government, since long before the end of the last great war, has had a policy of out-right lying to its sheeple for reasons of social engineering. The Allies and the Soviets both compounded this habit considerably when they took over their halves of Germany.
In reality, and any visitor can attest, Germany is THE meat and potatoes industrialised nation of Europe. Behind the 'green' propaganda lies a nation that actually does everything conventionally, and very effectively. Those involved in industry know the truth. The dribbling sheeple that need to believe 'green' propaganda don't have opinions that matter.
Now this isn't to say that Germany's concern about reducing pollution and looking after the environment isn't a good thing- it is. However, such concerns have NOTHING to do with 'green' propagandists/politicians and everything to do with improving the living experience of the general population as a nation advances, grows richer, and is able to keep its house in better order.
The 'greens' in Europe have proven themselves time and time again to be neo-fascist, and as such are a VERY disturbing political block. Renewable energy, like eugenics, are bad jokes, but both have found traction in Germany as mechanisms to further much darker political objectives. German 'greens' were fully in favour, for instance, of providing the obscene racist state of Israel with free German submarines specifically designed to carry Israel's genocidal nuclear warheads.
Yes, and who was the fool that put a nuke plant in a coastal tsunami prone part of the world.
GE.
Shouldn't the article say that ... the SUN produced (whatever) amount of power ... and didn't even notice it? Germany is just learning another way of harvesting the output of that nuclear furnace.
Ah yes, crony capitalism. Like all of the cronies who have collected the ~$10T we've pissed away over the past decade on such national treasures as our multiple ongoing wars, an unmatched prison-industrial complex, corporate welfare and bailouts for billionaires, and national defense and security. A hefty price tag, but I guess we did get a lot for our money. We got a new surveillance state, militarized police forces, dismantling of the constitution, and a recession bordering on depression while the elite have never been richer or contributed less. Let's also not forget that we nailed down the #1 spot on the Incarceration Rate Hot 100 (not to mention the #1 spot on many other prestigious charts), and as a bonus, our global resentment is at an all time high!
But I hear you, let's focus on the negative waste like green energy subsidies that cost less than what is filtered to war profiteers every month to keep Operation Occupy Afghanistan running indefinitely. We should also probably bitch about even thinking about providing healthcare to our citizens, and don't even get me started on those leeching retirees who demand a monthly cash handout just because they worked their whole lives paying into social security. What a waste.
Can't 50MW run a decent sized city and a couple GW run a small country or US state? This is 5 TW of just solar? That's 5 million megawatts. There's just no way unless they covered their entire country in solar panels.
I've seen people with bugs up their asses over religion, abortion, copyright and just all kinds of things which I can understand people being passionate about one way or another.
But you..?
You appear to hate the Sun.
That's messed up, man.
Some more info - I am a German living in Germany, and I've been following non-mainstream media on this very topic for quite a while.
Solar and wind are exploding, much quicker than anyone expected. In fact, so quickly that it has the government in panic, probably courtesy of the big energy corporations. You see, most solar and wind power is decentralized, deployed in small batches by thousands of small companies or private owners. The plans for big off-shore wind parks are moving ahead much, much more slowly.
So, the government broke their own promises, retro-actively(!!!) changed the law and reduced the subsidies for clean energy. When you read "subsidies" you should realize that both coal and nuclear are also heavily subsidized. With the recent changes, more so then renewable energy.
In addition, a law that exempts the really huge energy users in the industry was massively expanded and these days most energy-heavy industrial users are exempt from energy taxes. This makes electrical power a lot cheaper for them then for the consumer, who of course needs to pay for the difference. The purpose of this is obviously to reduce public support for renewable energy, because it has all been accompanied by a massive PR campaign about rising energy costs.
The fact is that the actual price of electricity has come down. If you look at the power exchange (like a stock exchange, just for energy prices), there were days when the price of electrical power was negative for several hours. Yes, that's right, there was so much energy being produced that the producers paid you for taking it off their hands. Sounds insane, isn't - electrical energy can't be stored easily, and you can't just make it vanish. If supply and demand aren't in balance, the stability of the energy network is in danger.
Of course, private consumers didn't notice and weren't given cheap energy. See above.
There's a massive political tug-of-war going on within Germany right now. On the one hand there are hundreds of mostly small or medium-sized companies that are driving the renewable energy market, building and installing wind turbines and solar panels. On the other hand are about half a dozen big old energy-power companies who simply missed the boat and are still heavily invested into coal and nuclear. There's a whole story there about the Germany government's flip-flopping on nuclear power over the years, too much to include in this post.
Assorted stuff I do sometimes: Lemuria.org
Due to the over-production of renewable energy (which of course is a good thing), prices for electricity at the markets are constantly dropping, with some electricity actually being paid to the recipients (!) at times ... at the same time, guaranteed prices for its production (in an attempt to stimulate building of renewable energy sources, with fixed rates for 20 or 25 years!) at rates of 3-4 times the wholesale market prices are causing EEG-rates (sort of a tax to pay for the guaranteed prices for the producers) to rise further and further, leading to constantly rising prices for consumers ... to add to that, energy-hungry production processes are exempt from that "tax", which again is added onto the tax for regular consumers ... so instead of profiting from the dropping prices on the market, consumers are forced to pay more and more ... great job, politicians!
Add to that the almost "fraudulent" way of making consumers responsible for delays e.g. in the building of ocean wind farms ... if some wind farm can't be put up and in production in time, again the consumers have to pay the fines ... WTF???
P.S. - apart from the above, there have been laws put in place, forcing communities to use a certain percentage of their land for renewable energy production. Neat idea as such, but depending of the area, this causes some problems ... e.g., the area I live in has large woods, moderate farming and cities in the range of 30-60k people (core cities). According the scientific research, there aren't many places for wind energy production, and the only ones that come even close to a break-even point for production are naturally on hills/higher plains. Which - not very surprisingly - aren't where the cities or farming is, but the dense woods. In order to fulfill the required ratio of renewable energy areas, the generators need to be placed in the middle of the woods, destroying not only the rather large space of woodland around the generators, but also requiring infrastructure (wider asphalt roads), power lines, and causing additional damage to the fauna by constant noise and infrasound ... also we're talking not about some small windmill, but 600+ft high ones, with 400ft diameter rotors ... to add to that, our local government decided to sign a contract with a company for them to build the generators even before any results of the surveys were done, or before involving (or even telling) the community about it ... therefore, if the local people should successfully stop the project either through political pressure or legal channels, the community is probably liable for damages claims from that company ... ...
And then politicians wonder why people are fed up with politics
"I'm sure in the future you can just generate nineteen point twenty one jiggawatts from a windmill, but in the 1950s it's a little hard to do."
(-1: Post disagrees with my already-settled worldview) is not a valid mod option.
Don't let yourself be distracted by these impressive-looking numbers. After shutting down half of the nuclear power station, german electricity is generated mostly from coal. Solar and wind is just a small fraction. Less than 20%. Nevertheless the added cost of solar and wind is about 10 cents per kWh. This is already threatening to drive energy-intensive industries out of germany (which would undoubtedly be welcomed by the greens). If we continue to subsidize solar power as much as we do, energy will be so expensive that all major industry will move out of germany or produce their own power.
Conventional power production
http://www.transparency.eex.com/de/freiwillige-veroeffentlichungen-marktteilnehmer/stromerzeugung/Erzeugung-des-Vortages
Solar power production
http://www.transparency.eex.com/de/daten_uebertragungsnetzbetreiber/stromerzeugung/tatsaechliche-produktion-solar
(guess why they don't put them in the same plot. Solar and wind would look too pathethic)
Now don't get me wrong: in places like the south-west of the US where there is a lot of continuous solar power and the peak power demand is at the same time as peak solar power production due to air conditioning, it is a no-brainer to produce as much as possible from solar power. Especially given the very low panel prices. But germany is really not the right place to put solar panels. Offshore wind is OK since at least it produces peak power in the winter where the power demand is highest. And in some places in southern gemany there is enough sun to make solar power competitive.
But the subsidies need to stop, or we will have an economic desaster.
It is a great project and I am all for it. They are trying but need investment and that is hard to come by because most investors are interested in production and not storage.
By the way did you notice that the efficiency of the two existing compressed air plants are 42 and 54%. That would mean that the daytime rate would have to be about twice the night time rate to break even. That does not take into account the costs for running and maintaining the compression plant. with that taken into account the night time rate would have to be 1/3 the daytime rate. That is not going to happen any time soon.
Finally, Germany does not have separate day/night rates.
According to this electricity prices have risen 61% since 2000 making it the most expensive electricity in Europe. That rise is blamed on renewable. It is cool to break records but at what price?
In Portugal solar energy had guaranteed subsidized rates (feed-in) around the 300€/MWh, or even 500 €/MWh in microgeneration (for a few years). The price in the free market where all the energies are negotiated have an average price of 40€/MWh. Wind energy have a guaranteed rate around 90€/MWh. This is completely unsustainable, making our energy cost extremely expensive, although the price to the public still not reflect the total cost, the difference is accumulated in an tariff deficit, a kind of debt. In Portugal this deficit is around 4000 million € in Spain 20 million €. It's a time bomb.
Renewables are doing so well in Germany that their neighbours have cut the German grid out, got tired of seeing their transformers burn: http://www.praguepost.com/news/15258-region-german-green-energy-push-needs-a-rethink.html
and German companies are moving to inhouse power generation because they can't take the losses caused by power fluctuations: http://www.spiegel.de/international/germany/instability-in-power-grid-comes-at-high-cost-for-german-industry-a-850419.html
The charts do not demonstrate the total cost to the consumer. There is only one way to determine this cost, look at the wholesale electricity price, this can be found here (coupled to the German market): http://belpex.be/marketdata/dam/public/images/CWE-MCP-Chart-FP-Big.html you can see the price is dropping when the sun is shining. Solar is being subsidised as the holy grail. Even the government cannot continue to swim against these market currents. It is better to look at alternatives like gas-(or wood pellet)-cogeneration, saves large amounts of CO2, this has at least got some flexibility in it, and it can be produced during "expensive periods". Wholesale prices have a lower boundary at +- 17-20 Euro per Mega Watt hour, an upper boundary of +- 60. Have a look at your bill and tell me "what explains the difference ??". This is all about excessive overhead in ex-government monopolies with some juice of unrealistic greenery on top. Nothing to see with a technical solution.
The German Army may have something to do with it: http://www.spiegel.de/international/germany/peak-oil-and-the-german-government-military-study-warns-of-a-potentially-drastic-oil-crisis-a-715138.html
To be, or not to be: isn't that quite logical, Slashdot Beta?
The other 55 percent (8 Billion) in tax subsidies goes to Oil/Coal industry PRODUCTION (you conveniently forgot to mention the remainder.)
The energy efficiency tax breaks are not part of the production subsidy amounts as they go directly to millions of energy consumers. Not energy producing industries.
Lies, Damn Lies, Statistics, and cherry-picked percentages.
OK, did Germany make solar energy, or did they make electrical energy from solar power? If the first, that's an awful waste, as normally it's free, if the second, most of the original post is incorrect! ;-)
Eurozone countries? You realize that's only the sub-group of countries within the EU that use the Euro currency? 50 countries in Europe, 28 members of the EU, 18 that use the Euro (Eurozone).
The solar cells cost is largely measured in the energy made to create it. Efficiency = output/cost. We just reached parity in 2010- that's pretty pathetic. And that doesn't include the costs of transportation, loss due to damage from hail, etc, and other such issues. Until this ratio becomes really large (10x), solar cells aren't much better than a battery- you put energy in and get it back out later.
There have been many promising technologies 'on the horizon' that are supposed to make solar cells cheap (made with little energy).
This is the most recent article of printable solar cells. I read one just like this 10+ years ago:
http://www.wired.co.uk/news/archive/2013-05/17/a3-printed-solar-cells
Then you have the "new material" of the hour:
http://www.technologyreview.com/news/517811/a-material-that-could-make-solar-power-dirt-cheap/
And all the other stuff, such as:
http://www.extremetech.com/extreme/163561-the-key-to-cheap-solar-power-may-have-been-discovered-over-150-years-ago
Until something radically changes, these 'investments' in solar companies are really just there to line to pockets of political cronies, like the 33 companies that made large donations to our president and received even larger 'investments' which were paid out before the company declared bankruptcy

Well spoken, Bruce!

This is likely just feeding a troll, but nuclear plants run by using fission to produce heat. That heat heats water to steam to run through turbines to make electricity. That steam needs to be cooled. The fission reactor needs to be cooled.
So nuclear plants need HUGE amounts of water. Big lakes, big rivers, or the ocean. That's it - it needs to be by one of those three. Coincidentally, that's where people live in large numbers. If we could stick the plants out in a remote desert we would. We can't.
You plan as best you can - they did pretty good in Japan actually. First you had the earthquake - boom. As a result you shut down the nuclear plant. So no power to run the pumps. Use backup generators for that. Tsunami hits - bigger than the protecting wall can handle. Takes out the backup generators, so no cooling again. Get portable generators in - oops! Can't hook them up - power couplers are incompatible. Guys running the plant don't make all the correct decisions from there - they make a few mistakes, wait too long to do some things, trying to save the plant rather than wreck it forever.
And there you have it - all of that had to go wrong, in order, for ONE reactor at ONE nuclear plant in all of Japan to have a meltdown - that was contained pretty well all things considered - while 10s of thousands lost their lives to natural disaster-S that caused it.
Friggin' Monday Morning Quarterbacks, the lot of you.
Germany is one of the worst places in the world for solar power, partially due to the latitude, but mostly due to the cloud coverage. These maps show the effective insolation, taking into account cloud coverage and sun position averaged over a year: Insolation world map, and Germany compared with the USA.
34% is remarkably high when taking into account how cloudy Germany is (and most months do worse than that). It is amazing that Germany has made solar power work as well as it has. Solar power in California would automatically be 2.5 times as economical as it is in Germany, and it would be 3+ times as cheap per W in Australia.
So people shouldn't be thinking "Germany is showing us that solar power is inefficient", but rather "If even Germany can make solar power work, then it will be trivial for everybody else".
They produced 5.1 TWh/month = 7.1 MW. I wish they had produced 5 TW, but you're off by a factor of 720!
I'm ready for the flood of excuses (technical and not) about how the US could do it but...
Man, we are so fat and lazy.

You are obviously not here to have a conversation on the original topic nor are you looking for information.
Cause clearly, you're the only intelligent person on the planet and no one came up with those questions before, prior to starting to invest billions in that fad of a project they've been running for years and plan to continue running for decades to come.
Clearly, all those people with their sciency engineerity and stuff are buffoons and morons, throwing all that money on a pie in the sky. Buffoons I say!
Or... It could be that your goal is to just keep being negative, bringing up one irrelevant argument after another.
Cause if it weren't so, you'd find both answers to your loaded questions and rebuttals to your foregone conclusions in the links I gave you previously.
I actually COULD have spent this post answering to all your pointless questions and tearing down every single one of your nonsensical points (which is to say ALL of them) but I simply refuse to do it.
Nope. I won't even let you know what are the HVDC losses. Let me check if I remember them correctly. Yup. I do.
But I won't tell you. Look it up yourself. Clearly you are capable of hitting Ctrl+f.
I've wasted way too much time and patience on you as is. This conversation is over. Good night.

Hemp doesn't compete with woodpulp, either, but both make paper.
Nuclear manages 60%, solar and wind 20-30%.
Your calculations are based on your hoped for conclusion, not reality.
They'd be foolish to evacuate..... If they left they'd miss out on that Darwin award! http://evacuatefukushimanow.wordpress.com/2013/07/30/%E7%A6%8F%E5%B3%B6%E3%83%BB%E3%81%84%E3%82%8F%E3%81%8D%E5%B8%82-swimming-in-fukushima/

Record power in the summer sun. Talk to me about a shitty February day and I'd be impressed.
As a Tsunami hit them - let's ban "Acts of God" and all make a saving on our insurance.
