Wind Turbines are a Huge Disaster….the Whole World Over!

More on Germany’s Wind Power Fiasco

turbine-collapse-germany1

The Germans went into wind power harder and faster than anyone else – and the cost of doing so is catching up with a vengeance. The subsidies have been colossal, the impacts on the electricity market chaotic and – contrary to the environmental purpose of the policy – CO2 emissions are rising fast: if “saving” the planet is – as we are repeatedly told – all about reducing man-made emissions of an odourless, colourless, naturally occurring trace gas, essential for all life on earth – then German energy/environmental policy has manifestly failed (see our post here).

Some 800,000 German homes have been disconnected from the grid – victims of what is euphemistically called “fuel poverty”. In response, Germans have picked up their axes and have headed to their forests in order to improve their sense of energy security – although foresters apparently take the view that this self-help measure is nothing more than blatant timber theft (see our post here).

German manufacturers – and other energy intensive industries – faced with escalating power bills are packing up and heading to the USA – where power prices are 1/3 of Germany’s (see our posts here and hereand here). And the “green” dream of creating thousands of jobs in the wind industry has to turned out to be just that: a dream (see our post here).

Now, Germans are fast waking up the unassailable fact that wind power is not only insanely expensive, it’s utterly meaningless as a power source.

Here’s a couple of no-nonsense pieces from NoTricksZone spelling it out in pictures, of the kind that the wind industry bends over backwards to ensure that you’ll never see.

THE CHART Wind Energy Proponents Fear You’ll See … Offshore Wind Turbines Stay In Bed 4 Of Every 5 Workdays!

Yesterday I published a piece by Fred F. Mueller on Germany’s out-of-control renewable energy transition and how it is in fact transitioning over to a disaster.

What follows below is a graphic that proponents of the offshore wind energy industry don’t want anyone to see. It tells the whole story about how (in)efficient and (un)reliable German offshore wind energy really is (Hat-tip: www.achgut.com) (for a clear look at the graph, click on it and it will open in a new window):

Wind-Energy-AWOL_R-Schuster

Chart shows the installed nameplate offshore wind capacity (shaded green) and the actual output (blue shaded area) since 2009. Wind’s poor performance and unreliable, wildly fluctuating supply disappoint and risk sinking Germany’s “Energiewende”. Chart source: R. Schuster.

The above chart was prepared by Rolf Schuster, an industrial engineering designer, who during his free time has started a wind power databank in order to check the rosy claims being made by the wind power lobby. The results are not something any fast-talking salesman would want any potential buyer to see. The power that was input (blue) is a mere fraction of the rated capacity (green).

Schuster writes:

“If you divide the power fed in (blue) by the rated capacity (green) you get the percent of the rated capacity that actually gets fed into the grid. The linear trend shows a negative tendency – towards 20 percent of the rated capacity. That means: Despite the massively increased capacity in 2014, hardly more power has ended up getting delivered compared to the start of the year. Only one fifth of the rated capacity actually gets fed in.”

Many proponents used to argue that the wind is always blowing at the North Sea, and so a steady supply was a sure thing. Now we have real results coming in. That “steady” wind is only delivering 20% of the installed rated capacity. A fiasco.

Schuster also says that offshore turbines have serious technical problems as well. Foundations are being washed out from underneath; there’s corrosion, and overloads that lead to turbine shutdowns. The harsh conditions of the North Sea a proving much tougher to handle.

There are also major problems with the high-voltage direct currentsystems that have yet to be solved, Schuster writes. One entire North Sea wind park has been disconnected from the grid as a result. This, Schuster says, “makes one ask if the installation of a major power transmission line from North Germany to South Germany would be a high risk gamble for the German energy supply”.

Green power goes AWOL again!

Also a look at online energy portal Agora here also tracks renewable energy that gets fed into the German power grid. A look at today’s graphic for the last 31 days tells us that once again wind and solar have gone AWOL, and so conventional fuels such as gas, nuclear and coal have to jump in to bail out.

Agora-5-Feb-14_25h

The above chart shows German energy supply and consumption for the last 31 days. Solar power that was fed into the grid is shown in yellow. Wind power is shown in blue. Cropped from Agora. (for a clear look at the graph, click on it and it will open in a new window)

Yesterday, February 4, we saw very little wind power getting fed into the grid, less than a gigawatt from a nameplate capacity of some 55 gigawatts of installed capacity – less than 2%! On February 4 wind and solar together virtually fed in almost nothing into the grid. If it had not been for coal, gas and nuclear, the country would have gone dark.

Germany’s “Energiewende” Leading To Suicide By Cannibalism. Huge Oversupply Risks Destabilization

The coming age of power cannibalism…Germany on the verge of committing energy suicide
By Fred F. Mueller

German politicians see themselves as the saviors of our climate. In the early 1990s German politicians started the policies that ultimately culminated in the “Energiewende”, which aims to eliminate nuclear power generation and some 76% of the fossil fuel power generation. By 2050 some 80% of power generation should come from “renewable” green sources such as wind, solar, biomass, waste incineration and hydro. Since the volatile sources of wind and solar power will have to contribute the lion’s share, politicians reluctantly concede 20% of the energy coming from reliable fossil power sources.

Germany’s endeavor is indeed breathtaking. A look at Figure 1 shows in detail how massively Germany had once relied upon fossil and nuclear power sources to secure a highly reliable power supply. These sources were controllable and highly reliable. And because Germany’s topology offers only limited possibilities for hydropower, that renewable source is minimal.

Mueller_1

Figure 1: In 1990 the German grid was able to count on conventional power sources which were controllable and highly reliable. Renewable hydropower accounted for only 3.6 %.

Today, after some two decades of massive green energy policy, the situation has changed dramatically. Wind, solar, biomass and waste incineration plants have been promoted to such an extent that together with hydropower, the share of “green energy” today has reached 25.8 % of the country’s total electric power production. This resulted from Germany’s EEG renewable energy feed-in act which guarantees producers fixed rates for 20 years and forces power companies to buy up all the renewable power produced, regardless of the market conditions. The result has been a massive oversupply which has led to steep price drops on power trading floors, which in turn have pushed fossil fuel utilities to and beyond their profitability limits. Surplus production has been repeatedly dumped onto neighboring markets and resulted in massive disturbances for the respective national power grids. Readers interested in a more detailed description of the policy might have a look at the article of Marita Noon [NOON].

Capacity without control

The problem with the “renewable” power sources of wind and solar is their intrinsic volatility coupled with their poor capacity utilization rates of only 17.4% for wind and 8.3% for solar (average values for Germany).

That poor utilization rate means one has to build up huge overcapacities in order to achieve a certain amount of power production. Worse, the power source fluctuates wildly according to weather conditions. As a consequence, Germany has to maintain a dual power generation infrastructure that comprises a grossly overinflated capacity of “renewable” wind and solar power plants shadowed by a full scale backup set of conventional plants. These conventional power sources must always be on standby, ready to take over when weather conditions aren’t favorable. The production-fluctuation range of the “renewables” wind and solar is incredibly wide and volatile. For example in Germany there is an installed nameplate capacity of nearly 73,000 MW. Yet the minimum power output in Germany in 2014 from both sources was a meager 29 MW (only 0.04% of installed capacity) while the maximum value was 38,000 MW (48%).

The massive buildup in wind and solar power has already resulted in a considerable nominal overcapacity of “renewable” power sources.

The combined rated capacity of all “renewable” power sources already reaches about 87,000 MW, which is the maximum power consumption the grid has been designed to secure. Additionally, a minimum conventional power station capacity of some 28,000 MW has to be constantly connected to the grid in order to secure supply stability. As a result the risk of the grid reaching an oversupply situation if weather conditions are favorable for both wind and solar power plants is growing with every additional “renewable” plant that comes online. Currently 5,000 – 6,000 MW are getting added each year. That situation is aggravated by the fact that there exists no technology to absorb and store any noticeable quantities of oversupply. Neighboring countries are already taking measures to fend off surplus-power-dumping that could destabilize their grids.

Power cannibalism has already started

The result is a grid which at times is so oversupplied with power that something will have to give. Fossil fuel power plants have been throttled to the point where they are no longer profitable and many power companies have started mothballing them, so quickly in fact that Germany had to pass legislation forcing producers to keep their fossil plants on stand-by, and to do so even if they lost money. Even the reliable “classic” renewable power sources – e.g. hydropower – are starting to suffer because most are not supported by government schemes.

As the build-up in renewable capacity continues, even the subsidized “renewable” power sources will sooner rather than later be forced into fierce competition for access to the grid whenever the weather conditions turn favorable. One can speculate that within just a couple of years, the first “renewable” energy sources will slowly be driven out of the market because of oversupply. Eventually the renewable power producers will be forced to cannibalize each other in an increasingly fierce competition for privileged access to the power grid as the unwanted events of over-supply become increasingly more frequent.

Things are set to get much worse

Normally, one would think that a government confronted with such a situation would stop at this point and wait for a technically and commercially viable solution for storing the increasing amounts of produced surplus electric energy – for use during times when weather conditions are less favorable. Unfortunately no such storage solution is currently available at the required scale, and anything being proposed so far is either much too expensive or has efficiency factors that are not worth discussing.

Yet Germany has a unique peculiarity: its leaders sometimes exhibit a stunning inability to recognize when the time has come to abandon a lost cause. So far €500 billion has already been invested in the “Energiewende”, which is clearly emerging as a failure. Yet all political parties continue to throw their full weight behind the policy rather than admitting it is a failure (which would be tantamount to political suicide). Instead, the current government coalition has even decided to shift into an even higher gear on the path to achieving its objective of generating 80% of German electric power from “renewable” sources by 2050. If the situation is practically unmanageable now with 25% renewable energy, it’ll be an uncontrollable disaster when (if) it reaches 80%.

If the government sticks to its targets, the share of the different power sources will probably appear as in Figure 2. Currently just 26% has been achieved so far, and the existing biomass share of some 7% is more or less doomed and thus will also have to be replaced by wind and solar. One can easily see how daunting the task that still lies ahead really is.

Mueller_2

Figure 2. The official goal of achieving 80% power supply from “renewable” sources by 2050 requires further massive investments in wind and solar power technologies. Imagine the huge power supply fluctuations one can expect to see from wind and sun.

Waiting for the grand finale

The real risks that lie ahead for the German power generating infrastructure become more recognizable if one looks at the nameplate capacity buildup that has taken place, e.g. just over the past five years, and compares it to what will additionally be needed by 2050, see Figure 2. Keeping in mind that €500 billion have already been contracted and will have to be paid by the consumer, one gets an idea of the proportions of the task still to be tackled in the coming years.

Mueller_3

Figure 3. The installed nameplate power production capacities for wind, solar and biomass as of 2014 has already severely burdened the German consumer with costs of about €500 billion. That will dwarfed by what lies ahead, if politicians don’t change course. Note how 376,000 MW of wind and sun capacity may be installed to ensure meeting the country’s roughly 70,000 MW of demand.

Apart from the sheer dimensions of the costs that lie ahead, the additional cannibalism aspect will grow to enormous proportions. Since an installed wind and solar capacity of some 73,000 MW in 2014 yielded a combined maximum power output of 38,000 MW, the 376,000 MW that are to be installed by 2050 will generate a peak output of 196,000 MW to a grid that might just be able to take up between 40,000 and 90,000 MW. That means, depending on the weather, between 106,000 and 156,000 MW will have to be dumped somewhere else.

In the fight to get power into an often times severely overloaded grid, that’s when cannibalism amongst “renewable” power sources will really become intense. Will wind farmers sabotage solar plantations? Will solar owners sabotage wind turbines? Time will tell, maybe much sooner than we think.
