I could have put this in the Europe thread, so if you move it, that would make sense....

Germany has experienced a "wind drought," and their wind mills did not generate energy...showing us, once again, why basing your nation's energy supply on wind and sun is stupid...

Energiewende, or “energy transition” in English, is Germany’s comprehensive plan to transform its energy system towards a low-carbon, nuclear-free economy. This green-fever-dream includes significantly increasing the share of renewable energy sources while phasing out nuclear power and reducing reliance on fossil fuels.


For years, the Germans have religious implemented energiewende. They have been so efficient that wind energy has become the largest source of electricity at 27.2%, overtaking coal at 26.8%.

However, in their rush to achieve “net-zero”, the Germans forgot another of their words: Dunkelflaute (wind drought…literally “dark calm”).

Dunkelflaute typically occurs
during winter months, particularly in November, December, and January. And it appears that the projection is for slowing wind speeds over the next few decades, too.

During these periods, wind turbines and solar panels produce little or no energy. Germany has tried various kinds of battery storage to get through the annual dunkelflaute, but the only thing that has really bailed out their power grid is nuclear, and burning more coal and natural gas
Germany and Northern Europe have been experiencing a variation of dunkelflaute, called “wind droughts,” for the last few years, with wind speeds falling 15% or more in many regions. This has been a gradual trend since 1978. The projections for wind drought continue to get worse. Even the IPCC is forecasting slowing winds for the coming decades, saying average annual wind speeds could drop by up to 10% by 2100.
A single event usually lasts up to 24 hours, with 2-10 events occurring per year, totaling 50 to 150 hours annually.

That's a shame.
I'll bet they wish they still had some clean, reliable nuclear energy to keep them warm in winter.
 
The wind don't blow most nights. There are weeks months days hours the wind don't blow.

Yet, we build wind turbines, by the thousands. Heavy industry build wind turbines with oil!

They build wind turbines every day all day and night, from now until the oil runs out.
 
Fields of solar taking over farms in central MN.
Hundreds and hundreds of acres.
Kills the landscape, forces wildlife out, ugly as fuck, and worthless in winter covered in snow with low sun and short days
 
Where it rains every day all day long ... hydro makes perfect sense ... cheapest electricity in the nation ...
So long as there is a way to dam it, and run your turbines from it, you're correct. Hydroelectric is the bees knees.

There lies the rub ... dams and turbines are extremely carbon-intensive to produce ... but that can be amortized over several human lifespans ...

We have clean abundant mountain fresh spring water ... watching it all flow into the Pacific Ocean is enough to make an anchor weep ... the energy's nice but all those thirsty people living in the Desert Southwest ... and we just throw water away ... such a shame ...

Gotta save the smelt or something.
