Germany Produces Record-Breaking 5.1 Terawatt Hours of Solar Energy In One Month 687

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."

          Sensationalism much? They feel fine...only their warm-fuzzies were really effected and mostly due to trauma from either proximity to the plant's fire or due to the massive fucking tsunami that caused all of the actual problems . (http://www.cnn.com/2013/02/28/world/asia/japan-who-radiation [cnn.com])

          The lifetime risk of contracting certain types of cancer rose slightly for a small group of people because they were exposed to radiation from the nuclear disaster, the WHO said Thursday.

          The notable exception was young emergency workers at the plant, who inhaled high doses of radioactive iodine, probably raising their risk of developing thyroid cancer. But since the thyroid is relatively resistant to cancer, the overall risk for these people remains low, the report said.

          Otherwise, any increase in human disease after the partial meltdown triggered by the March 2011 tsunami is "likely to remain below detectable levels," the WHO said in its report.

          So basically the tsunami and resulting devastation from the tsunami's aftermath are what the people in Fukushima are really concerned about...not growing extra arms or dying of cancer any sooner than they already would have. The real question for people there is whether or not they are willing to pay double price for their power and be safe from the apparent nuclear menace that is destroying lives...I'm betting people like cheap power.

                No it is called "Windgas" or "Power-to-gas" where you just produce hydrogen or even methan with renewable energy (mildly efficient: 50-67% power -> gas -> power) and inject it into the gas network. There already working prototypes (granted I think they are all sub MW stations). But they improved from 25kW to 500kW within 3 years (2009 - 2012). Nice sideeffect is that in theory renewable energy could in the long run power our gas-cars and gas-heating and highly efficient gas-power stations.

        Nuclear subsidies are in your taxes, where you don't see them. Solar subsidies are in the electricity price, where you see them. Nuclear energy is not cheap energy, and while it does work for base load, you only need to look at France in the winter and in the summer to see that relying on nuclear does not cover all loads, so you also need other power plants on standby, so nuclear does not have an advantage over wind and solar there.

        If you don't put on price on energy usage then there's no incentive for appliances and lights to become more efficient. Sure you pay more, but Germany is proof of what can be achieved with solar and wind. BTW Germany's economy is the best in the EU; they were last seeing bailing out the rest of Europe.

        Don't ask how much something costs without also asking what you get for your money. Germany gets closer to energy self-sufficiency , creates a proof not of concept but of implementation for the rest of the world to benefit from which can and will offset more climate change which saves Germany and everyone else the astronomical, nation destroying costs - which will ultimately fail after they bankrupt us- involved with trying merely counteract climate change.

        So what is the financial cost? It's negative, because the very people paying higher electricity costs today will be spared having to fork over the all the rest of their money to battle climate change later.

        Don't ask how much something is, that's a brain-dead question. Ask what are you're getting for your money, and set the horizon for analysis to be the rest of your life, at least, or even your children's lives if you're the sort of person who is capable of being about something other than just yourself.

      Well to quote the wikipedia page quoting a financial times article:

      Due to the costs of this "Energiewende" Germany now has Europes highest energy costs. Costs have risen over the last 5 years even for industrial consumers who are exempted from the costs of the renewable energy subsidy that consumers pay. In 2013, energy was 4 times cheaper in the United States than in Europe, and 6 times cheaper than in Germany.

      It comes at a price and the sweet spots to produce renewables have already been picked, to keep it up they must use less and less ideal areas and means. Nice to see them lead but it's not really an act the whole world can follow.

If you compare Germany to similar north western European countries it isn't particularly expensive. Other countries happen to have some nice natural resources, or they subsidise the cost through general taxation (especially for nuclear power).

        Sure it can. At the cost of higher energy price.

        There's lots of related stories.

        I just read in a somewhat recent magazine (0-2 year old) how here in Sweden/Scandinavia I think they was often recycling 90-95% (or just 95%) of the building material when they broke down a building.
        In the rest of the Europe they was trying to reach 50-95% (or 50-90.)
        In the US? 20%.

        There's also that story about that plastic stuff in the pacific.

        Over here in Sweden almost all aluminium cans are recycled, you pay 1 SEK for them when you get your drink and you get 1 SEK back when you recycle them. When people go out and drink (and just throw or put down their beer somewhere) or maybe leave their soda cans some people browse the cities for cans and look through the trash cans to pick them up and return them.
        We do the same for glass (1 SEK) and PET (1 or 2 SEK) bottles.
        We have had the same system for beer, cider and wine bottles to. I don't know how it works atm because I don't buy them anyway.

        I'm supplied with a compost bag holder and free paper bags to put my compost in and suppost to drop that content into a compost box outside. At the parking lot (same area) I can also leave all packaging which is made of plastic, metal, glass, cardboard and papers&magazines.

        In general the rest garbage is burned for long-distance/district heating (and there's places which burn more nasty stuff to.)

    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.

  • 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
    • Interesting. Actually, first incentivizing consumers at the expense of utilities, and then later doing the opposite, might make sense from the perspective of a revenue constrained country like Germany.

      The trouble with California is that the rules depend on when and where you bought in. Some people are only allowed to earn back up to the connection fee.

    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.

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.

      I think a big part of it is outrage at the "idiots" who are don't understand nuclear power and are afraid of it, ruining the party for everyone else. You see a lot of people ranting about the "scientifically illiterate greens" and hippies who want to go back to the stone age, so it's clear they don't listen to or understand the actual arguments or developments in technology.

      It's a common problem everywhere. Find some group to blame and vent anger at and the momentum builds by itself.

    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.

    • Woah, hang on there on the daylight calculation. You have to factor in the angle to the sun. At dusk and dawn, your panels will be rotated at glancing incidence to the sun, they won't be presenting very much surface area to be illuminated.

      Assuming the produced power scales linearly with received intensity (I'm not willing to bet on this assumption....), if I've done my math correctly, you can only expect the average to be about a factor of 1/pi of the peak. How do your calculations work out if you normal

    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 [bbc.co.uk] 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 [wikipedia.org].

    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.

    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' [economist.com].

    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.
