EDIT: Many people are confusing installed capacity and energy production in their answers.
This isnu2019t necessarily fake news.
30% of Germanyu2019s power plants are renewables, but that doesnu2019t mean that during any given hour or day 85% of the countryu2019s energy demand canu2019t be supplied by renewables.
Itu2019s two completely separate metrics.
The difference is (total renewables capacity/total generation capacity of all resources) vs.
(real-time renewables generation/real-time demand).
This second metric is called penetration of the resource, for those who were wondering.
,ADDITIONAL EDIT: The Southwest Power Pool, a regional energy market and grid operator in the U.
Midwest/South, recently announced a wind penetration of 52.
1% in February (SPP sets North American record for wind power).
Of course, this happened at 4:30 a.
, when demand is low and wind production is high.
SPP didnu2019t announce what that did to prices or how much power was actually being generated, but it did point out that while it has 16,000 MW of wind capacity, its maximum simultaneous wind generation peak is 12,336 MW u2014 which is to say that only about 77% of the wind turbines have ever been able to run at the same time.
Thatu2019s actually pretty good, but still suggests that, even at peak output, about 1/4 of the turbines arenu2019t running.
(Or more likely, all of the turbines are producing at something well below their potential output, but you get the picture.
),Anyway, on to my original answeru2026,I think most conservatives would think, u201cAs with most things, liberals are cherrypicking the details that support their rose-colored, simplistic daydream of how the world should work and failing to grasp or even attempt to comprehend the complicated, often-conflicting dynamics that control how it really does work.
u201d,Yes, renewables might have supplied that much power at a specific point in time (even though your cited source doesnt actually mention that), but they cannot provide it consistently around the clock.
That means that other, more-reliable must also be built to make up during the low periods and a market structure created to incent investment in building those plants despite their very limited runtime.
That means prices will go up to accommodate for them.
In 2016, only about 30% of Germanyu2019s power came from renewables (which is actually a very impressive accomplishment relative to the rest of the world.
),Also, negative prices arenu2019t a good thing.
They distort market price signals and discourage investment.
Eventually, your system will weaken as the plants you need for reliability fail to get built.
They also dont mean cheaper energy.
German consumersu2019 bills have risen 50% since 2007 (Germanyu2019s High-Priced Renewable Energy Revolution).
US consumers would be outraged with that.
,Next, you have to consider the impact that Germanyu2019s influx of variable generation is having on its transmission system.
They are having a tough time handling it as the situation currently stands, and that is only possible because Germany is grid-connected to other systems that can absorb the sporadic deluge of power.
Were it a single system, the overgeneration would require either shutting down some of the renewable generation or risk frequency fluctuations that would, again, damage the system.
,Finally, Germanyu2019s resource mix is still heavily coal, and it runs often:,Germanyu2019s greenhouse-gas emissions have actually increased in recent years.
,So I think a conservative would think: u201cprices are up, investment is being stymied, emissions arent being reduced, risk of system failure is increasing and were still using a lot of the same resources we used when it was a lot cheaper.

I think human stupidity is an unexhaustible resource, and your question makes the point again if it ever was needed.
