Renewables don't risk blackouts, said the media. But they did and they do. The physics are simple. And now, as blackouts in Spain strand people in elevators, jam traffic, and ground flights, it's clear that too little "inertia" due to excess solar resulted in system collapse. 
Six days ago, the media celebrated a significant milestone: Spain’s national grid operated entirely on renewable energy for the first time during a weekday.
At 12:35 pm today local time, the lights went out across Spain and Portugal, and parts of France. Although power was quickly restored in France, it could take a week to fully restore power in Spain and Portugal.
In an instant, the electric hum of modern life — trains, hospitals, airports, phones, traffic lights, cash registers — fell silent. Tens of millions of people instantly plunged into chaos, confusion, and darkness. People got stuck in elevators. Subways stopped between stations. Gas stations couldn’t pump fuel. Grocery stores couldn’t process payments. Air traffic controllers scrambled as systems failed and planes were diverted. In hospitals, backup generators sputtered on, but in many cases could not meet full demand.
It was one of the largest peacetime blackouts Europe has ever seen. And it was not random. It was not an unforeseeable event. It was the exact failure that many of ushave been, repeatedly, warning lawmakers about for years — warnings that Europe’s political leaders systematically chose to ignore.
While Portugal’s grid operator REN initially blamed the mass blackout on “extreme temperature variations” and a “rare atmospheric phenomenon,” and while some media repeated that framing, the reality is more serious. Weather may have triggered the event, but it was not the cause of the system’s collapse.
Spain’s national grid operator, Red Eléctrica, revealed that the immediate cause of the blackout was a “very strong oscillation in the electrical network” that forced Spain’s grid to disconnect from the broader European system, leading to the collapse of the Iberian Peninsula’s power supply at 12:38 p.m.
“No one has ever attempted a black start on a grid that relies so heavily on renewables as Iberia,” noted @JKempEnergy . “The limited number of thermal generators will make it more challenging to re-establish momentum and frequency control.”
In a traditional power grid dominated by heavy spinning machines — coal plants, gas turbines, nuclear reactors — small disturbances, even from severe weather, are absorbed and smoothed out by the sheer physical inertia of the system. The heavy rotating mass of the generators acts like a shock absorber, resisting rapid changes in frequency and stabilizing the grid.
But in an electricity system dominated by solar panels, wind turbines, and inverters, there is almost no physical inertia. Solar panels produce no mechanical rotation. Most modern wind turbines are electronically decoupled from the grid and provide little stabilizing force. Inverter-based systems, which dominate modern renewable energy grids, are precise but delicate. They follow the frequency of the grid rather than resisting sudden changes....

Louder for the people in the back: Weather may have triggered the event, but it was not and cannot be the cause of the system’s collapse.
If you are an electric grid operator blaming the weather for your blackout, you should be fired!

And if you are a politician blaming the weather for blackouts, fires, or floods, the voters should fire you. Seriously! You're only advertising your own incompetence!

Politicians have been blaming the weather and climate change for blackouts for years! This is from 2021
Journalists, experts, and elected officials in July 2021 blamed heat wave deaths, forest fires, and electricity shortages in New York, California, and Texas on climate change, but the underlying cause of those events was lack of air conditioning, lack of electricity, and the failure to properly manage forests, not marginal changes to temperatures.
It’s true that there have been more heat waves in the United States since 1960, and that higher temperatures dry out the dead wood in forests, contributing to a greater area burned by forest fires. “Climate dries the [wood] fuels out and extends the fire season from 4-6 months to nearly year-round,” US Forest Service scientist Malcolm North explained to me last summer.
But what determines whether people die in heat waves is whether or not they have air conditioning, not whether temperatures rose to 111° instead of 109°. Proof of that comes from the fact that heat-related deaths declined in the US by 50% to 75% since 1960 thanks entirely to air conditioning, even as heat waves grew in frequency, intensity, and length.
What determines whether a fire in a forest is high-intensity or low-intensity is the amount of wood fuel. Climate change is “not the cause of the intensity of the [mountain forest] fires,” stressed North. “The cause of that is fire suppression and the existing debt of wood fuel.”
And what determines whether or not there is enough electricity is whether there are sufficient “baseload,” reliable power plants and fuels, not marginally higher use of air conditioners. The people who manage electricity grids knew perfectly well that it could be hot last summer, hot this summer, and that a cold snap like the one that occurred in Texas in February was likely, since worse cold snaps had occurred in the past.
The main reason there aren’t enough reliable power plants is because progressive activists, scientists, and journalists successfully persuaded policymakers to shut them down, not build them, or not operate them.
And the reason California has failed to properly manage its forests is because, for decades, its leaders underinvested in fire prevention, including by diverting money that the state’s electric utilities could and should have spent on clearing the area around electrical lines, to renewables...
