From NOT A LOT OF PEOPLE KNOW THAT

The latest energy trends data have been published by BEIS:
It is quite shocking to see that wind generation has fallen by 38% for onshore and 24% for offshore year on year. This is despite new capacity being added.
We are familiar with short term drops in output, maybe for a few days or even weeks. But to lose effectively a third of generation for a whole quarter shows just how dangerous over reliance on wind power is.
The difference was made up largely from imports, which doubled:
How long we can count on that is anybody’s guess.
Weather extremes are a product of CO2 induced warming, so long term adding wind power will result in steadier weather- further increasing wind capacity and efficiency
Just further proof of the need for more subsidies.
/I wish it were merely sarc
These are the kind of wind mills – not too efficient – that once served their purpose on scattered sheep (and cattle) farms in hot and dry areas. I wonder if their designers would be impressed with today’s monstrosities?

So they need to increase the renewables to >3x the current renewable capacity plus 10’000’000 MWh of storage (32’000MW peak) or mitigated by large gen capacity wasted (overbuild) for much of the year. The high costs would need to be paid again when they reach EOL.
The required storage or over building capacity are not currently economical for the required scale & time to cover 100% of natural variations of demand & supply.
They would need 10x energy density at <12% of current $/MWh (delivered).
The relative costs to the status quo (or fossil fuels) is ofcourse a moving target affected by many factors (YMMV). It won't happen overnight but it may in the future.
They are not “renewable”. This is marketing bs. Nothing about them “renews” other than the bs.
Winds and Tides threw gearing produce the speed of light wobbles then infinite values.EINESTIN kinrtics.

Steven,
If you haven’t been told previously, please do not post a comment at this (or any) website when you are high on pot.
Don’t worry about intermittency, new generations of batteries will be developed to store it. /s
Jeez thought you said intimacy there for a moment 😉
No one needs to guess. Anyone who has a basic understanding of weather systems knows the answer is never. Only foolish people believe that weather dependent generators are more than a fad soon to be condemned to history.
No one is going to spend another fortune replacing these monuments to stupidity when they prematurely fail.
Are windspeeds or wind power outputs dropping worldwide? Of course they aren’t.
a statistical blip.
especially when you bear in mind 2020 had HIGH output in several regions.
That just confirms the problem of renewable.
Variable day by day, week by week, month by month, year by year and decade by decade. Frequently zero.
When wind turbines don’t reach optimum output until wind speed is over 25mph your first point is irrelevant .
And under 50 mph. Over that speed, they can self destruct!
He just kicked an own goal.
And just to build on the point, electricity is needed on demand. Average power available over a day or even an hour doesn’t help most people or industries. It’s all about providing the power when requested.
Those huge drops in renewables output were the result of a few outages at fossil fuel plants.
Same as Texas.
And South Australia.
Its always fossil fuels which are the root of the problem. Just ask Greta…..
The maritime industry sorted this load of nonsense out many years ago. It dumped wind and went for fossil fuels to everyone’s benefit, including the plants.
If you look at the aggregate quarterly numbers you might get that impression, but if you look at the daily numbers an alternative explanation can be found.
Which generation source is “cut back” — in the case of “the island of Great Britain”, at least — during spikes in wind generation, e.g. from the end of July to the middle of August ?
Which source is “ramped up” when you happen to get a “wind drought”, e.g. from the middle of August to the middle of September ?
NB : Having a large percentage of total electricity generation coming from a source than varies between 25 and 325 GWh per day depending on what the weather is doing, despite having a (roughly) constant nominal “total nameplate capacity” value, isn’t “healthy” for a national electricity grid.
At some point, wind shadow effects will constrain output. Adding more capacity will be parasitic detrimental to existing capacity.
