Germany’s July Wind Energy Takes A Summer Vacation, Showing Country’s Renewable Energies Remain Unreliable

(Translated/edited by P. Gosselin)
In a guest article in the German DIE ZEIT, Rainer Moormann and Anna Veronika Wendland recently mentioned the subject of the nuclear phase-out. There is a replica of it at Erneuerbareenergien.de, written by Nicole Weinhold. In it the author puts forward the idea that a simultaneous phase-out of coal and nuclear power is possible solely in Germany on the basis of a CO2 price. Unfortunately, she does not explain exactly how this should work. A pity.
Some of the readers’ comments take up this specifically and come to the conclusion that more capacity of renewable energies does not automatically mean more electricity from them. The windless months of June and July 2020 are a good example of this. The Fraunhofer Energy Chart shows July, 2020. First of all, the yield of wind power:
Power production in Germany in July, 2020​

As the chart above shows, mid July wind energy went on summer holidays, in addition to a number of off days throughout the month.

Shown next is the energy supply breakdown for July:
Net power generation in Germany in July 2020​

The gray shows the non-renewable energy share, the yellow depicts the renewable share. ​
How do you replace 28% of electricity production when coal and nuclear power are no longer used?
How are you supposed to generate 50% of the electricity when renewables only have a 50% share in a summer month? As Ms Weinhold was told, scaling is not enough, because every number multiplied by zero is zero.
This all means Germany’s dream of being powered by renewable energies is a long way off.

Thank you for the link that shows that Germany gott around half of their electricity from renewables during July, just like they did the first six month this year. That during summer you get less wind power in Germany that is compensated by getting more power from solar power. That according to your source Germany got almost 18 percent of their electricity from solar power during July even with their northern location and relatively cloudy weather. That combining different types of renewable energy is one way to regulate supply and demand of electricity.

Renewables met half Germany’s power demand in first half

There energy storage and transfer electricity between regions are other examples of regulating supply and demand.

You're whistling past the graveyard.

To advance technology you need to take risk and have failures. There some like to solely on the loans that failed instead of the overall success and profitability of Obama administration's loan program.

"A blue-black field of 5.2 million solar panels tilted toward the Arizona sun might just be the Hoover Dam project of the Great Recession. The Agua Caliente Solar Power Project hosts nearly 300 megawatts of silicon photovoltaics (PV) that turn sunshine into electricity. That made the Yuma County facility the largest working solar farm in the world when it opened in April 2014. But when it comes to mega–energy projects, Agua Caliente has competition, including four of the world’s largest solar-power plants to use the sun's heat and one of the largest wind farms on the planet. And its all thanks to billions in loans from the U.S. Department of Energy’s Loan Programs Office (LPO).

The most important thing the Obama administration has done to combat climate change may not end up being raised fuel-efficiency standards for cars and trucks or even its Clean Power Plan to cut carbon dioxide emissions from power plants. The most important thing may turn out to be the loans that enabled large power facilities that run on sunshine or Earth's heat to break ground out west, wind farms to be built from coast to coast and construction of the nation's first brewery for biofuels not made from food—as well as a host of other advanced manufacturing energy projects."

The Dirty Secrets of “Clean” Electric Vehicles

The widespread view that fossil fuels are “dirty” and renewables such as wind and solar energy and electric vehicles are “clean” has become a fixture of mainstream media and policy assumptions across the political spectrum in developed countries, perhaps with the exception of the Trump-led US administration.

The environmental and social impact of renewable energy is tiny compared to the environmental and social impact of fossil fuels. Think for example of how tar sands operation leads to 500,000 Olympic swimming pools of toxic waste just a long one Canadian river. Or the devastating effects and costs of air pollution.

This is the world's most destructive oil operation—and it's growing

More than 90% of the world’s children breathe toxic air every day

That at the same time you have the devastating effects of climate change.

While yes renewable energy, electric cars and other green technology also of course have an social and environmental impact so it therefore it's good that it now is so much work to reduce that impact.

Being “conservative”, by definition, means fearing change and clinging to the past. In a universe where the only constant is change, and a world which is changing and being transformed by technology and new scientific understanding at an ever increasing pace, it must be a scary place to live for them, poor dears.

No it does not! just like all liberals are not in lock step, neither are all conservatives.
I am a fiscal conservative, and fairly liberal on many social topics,
I mostly think that Government should live within it's means, and be as small as necessary to get the job done.
I embrace change, we should move towards a consumption tax, that discourages spending,
as opposed to an income tax that discourages income!
We should also move towards carbon neutral man made fuels, as that path will lead to sustainable advances for our global population.

This is a comment that displays quite an ignorance of history. Conservatism is not about fear of change, but about understanding and managing change.

[h=2]Wind Power failure: on average every 3 days, there is a 500MW fail[/h]
[h=4]On average, every 3 days, wind farms generating as much as one coal fired unit, fail on the Australian grid[/h]TonyfromOz exposes a failure rate so common it’s hidden in plain view. Wind “Farm” intermittency is even worse than we thought.
On average, every three days within a one hour period there’s a sudden failure of 500 MW of wind generation — equal to one industrial coal turbine. That’s four full wind farms or about 250 spinning turbines that stopped spinning.
Every time a coal plant trips out, it’s reported as a problem of relying on our “old coal fleet”. But when the same power output fails from wind, it’s the new clean green future at work (!) , and a sign we need to spend another $20 billion to “upgrade the grid” with interconnectors we don’t need, and Hydro schemes we don’t want.
A few wind farms are bad for the grid. More windfarms are worse. . . .

More ironies. One fifth of all soil carbon is stored in peat bogs. Unfortunately when industrial wind turbines are built on them, the damage turns them from carbon sinks to carbon sources thus neutralizing the point of building the wind farm. . . .

What if fan miniaturization and airflow were designed into commercial buildings to use wind farming technologies safely in urban environments?
 
danielpalos said:
The point is, potentially, every commercial building could generate some energy not only consume it. With even more miniaturization, wind farming technologies could be less obtrusive and placed in more locations.

I know the point, but when Treehugger is pointing out the "folly" perhaps it is worth listening at to why!
I understand they now have clear solar panels,
Transparent Solar Panels: Reforming Future Energy Supply
making all the windows on the sun facing sides of a building, would be better than the mechanics of wind turbines, on the side of the buildings.
Some ideas are good in theory, but the implementation becomes more complicated.

As the cited article stated, loading, vibration, sound, and insurance.
The solar panels would have none of those, perhaps a bit higher insurance considering the higher value windows.

Miniaturization of wind farming technologies could incorporate miniature turbines into the buildings in a manner analogous to windows.

Smaller turbines, smaller output, eventually the law of diminishing returns will eat up any benefit.
We are only seeing the beginnings now, but wind turbines are a maintenance nightmare.

Miniaturization could mean entire components or turbines could be swapped out. Led technology is an improvement over incandescent. Advancing those technologies will surge with any capital investment for the bottom line.
