I saw some context for this, and the short of it is that headline writers want you to hate click on articles.

What the article is actually about is that there’s tons of solar panels now but not enough infrastructure to effectively limit/store/use the power at peak production, and the extra energy in the grid can cause damage. Damage to the extent of people being without power for months.

California had a tax incentive program for solar panels, but not batteries, and because batteries are expensive, they’re in a situation now where so many people put panels on their houses but no batteries to store excess power that they can’t store the power when it surpasses demand, so the state is literally paying companies to run their industrial stoves and stuff just to burn off the excess power to keep the grid from being destroyed.

Batteries are more than likely another type of pollution. I’m sure they can and will be recycled but just like the problem with our current capacity to recycle things it probably becomes untenable (guessing).

The state just needs to find ways to convert that energy into something else. I suggest desalinating sea water and pumping it up stream.

That’s not what I got from the article. (Link for anyone who wants to check it out.)

My interpretation was that decreasing solar/wind electricity prices slows the adoption of renewables, as it becomes increasingly unlikely that you will fully recoup your initial investment over the lifetime of the panel/turbine.

In my mind, this will likely lead to either (a) renewable energy being (nearly) free to use and exclusively state-funded, or (b) state-regulated price fixing of renewable energy.

You could theoretically build a coal pit in your back yard to turn the wood into coal, then power a steam engine hooked to generators to make electricity to run your computer.

The first factories were powered by waterwheels. Those were subjected to seasonal variations and limited geographic possibilities, what gave negotiating power to labor. Therefore the industry switched to fossil fuels, so they could run when and where they wanted, preferably near a city with excess labor force. It made it more expensive to run, but it was easier to exploit labor so more profit.

In the OP the use of the word “problem” rather than something like “challenge”, and referring to the problem being the pricing structure (negative) makes it seem like we’ve switched topics slightly, but if you are just referring to the foundational inefficiency of energy distribution then yeah I agree it is definitely a challenge. However, that challenge need not be so overwhelming (even perhaps solely wrt pricing) that it negates the benefits of having that form of technology available altogether. e.g. if the power company itself, or each recipient building individually, had its own battery (if let’s say those were cheap & sustainable) then that could work, without the users needing to care much. I forget which city but one example in Germany iirc pumps water up a mountain during the day, then at night or on a cloudy day that potential energy falling back down generates electricity again. So yes a “challenge” for sure but not necessarily an insurmountable one!:-)

Also, there are “problems”/“challenges” wrt use of fossil fuels as well, which have implications for climate change, and therefore even purely from a profit perspective there’s government laws & subsidies and public perception that can affect it, which could push the overall net towards being beneficial to store that energy for later.

The answer to this is local energy storage. It could be at the home level, but doing it by neighborhood/industrial block would be better

Then, you lessen the strain on the grid at large, and you also capitalize on the periods of low demand. This means less spot energy production and built in storage, making it easier to make the most of renewables while minimizing the need to fire up a natural gas plant to make up the difference

It’s pretty easy to imagine fusion being great - but it’s still just in our imaginations. No one has yet been able to build a working fusion power plant. There has been progress over the decades that people have tried, but its still a way to go yet. So although we can imagine that it could produce clean and plentiful energy, we just comparing sci-fi tech to current tech. The future reality might not be so great, and the current reality is that fusion power isn’t possible at all.

To illustrate my point, lets imagine solar power from a ‘theoretical’ point of view, like fusion is described. Solar power uses no fuel; gets its power from sunlight. There is enough energy coming from the sun to meet the whole world’s energy needs with just reality small amount of area. Solar power produces no waste biproducts… So if we just imagine the benefits of solar power, it sounds pretty much perfect. In in reality though, although solar is very good, it is still far from perfect. Construction, maintenance, and disposal of the panels are where the costs are. And so to compare to fusion, we’d need to know what it would take to build, maintain, and disposal of the fusion power plants. Currently we can’t do it at all - so the costs are basically infinite. But even if our tech improves to the point where it is possible… it’s hard to imagine it will be easy or cheap - especially because there will be radioactive waste. (Radioactive waste not from the fuel, but from the walls and shielding of the reactor, as it absorbs high-energy particles produced by the operation of the power plant.)

Every previous adoption of technology has taken - what, 50 years? - between having the technology and being set up to make use of it. Gasoline did not immediately have car engines to put into, nor kerosine a whole city’s worth of lamps set up to receive them, etc.

Though at first, if fusion could power up the existing electrical grid then it could e.g. make electrical cars more efficient in the net/overall sense, even if vehicles operating directly on fusion power themselves would take many more years. So fusion really might be different than those that came before, if we are anticipating and more ready for it than previous technical advances?

Though yeah, it will have its own challenges e.g. the radioactive wastes, so fusion would not begin to replace greener energy approaches such as solar, wind, and geothermal, only perhaps supplement them.

I’m personally very excited about how it does seem to be finally making progress if slowly, but realistically, I’m less convinced that it’ll be the solution to all our energy needs than many are. The physics of the process itself is very efficient, sure, but the kinds of machines needed to harness it are literally among the most expensive and complicated things built by humans, and they don’t even produce net energy yet. Granted, the cost of such things should be reduced once they are industrial machinery and not exotic scientific instruments loaded with experiments, but I’d bet that the reactors themselves will still be incredibly expensive and complex (and therefore have expensive maintenance). This doesn’t say good things about the actual cost of the resulting energy, even if the fuel is quite abundant. We could get abundant energy with a similarly high if not quite as much fuel efficiency with advanced fission reactors and fuel breeding, but the cost of those kinds of plants has been relatively prohibitive, and the costs of renewables has been falling. I could certainly see it possible for fusion to reach net energy, only to get used only on specialized roles or for base load power because solar panels end up being cheaper. In a sense this has already happened. It is theoretically possible, if not practically desirable, to use fusion energy in a power plant already, by detonating fusion explosives in a gigantic underground chamber full of water to heat it up, and harnessing the steam. Such ideas were considered during the cold war, but never developed, at least in part because it was calculated that they wouldn’t be cost competitive compared to other power options.

Both of the statements in that screenshot are just so inane.

Frequency has to be maintained on the grid. It’s the sole place where we have to match production and consumption EXACTLY. If there’s no battery or pumped storage storage available to store excess energy, the grid operators have to issue charges to the producers, in line with their contracts, to stop them dumping more onto the grid (increasing the frequency). The producers then start paying others to absorb this energy, often on the interconnectors.

It’s a marketplace that works (but is under HEAVY strain because there’s so much intermittent production coming online). When was the last time you had a device burning out because the frequency was too high?

Frequency has to be maintained, and it is trivial to do so when you have excess renewables because inverters are instantly throttle-able. The reason why you’ve never heard about devices failing because frequency is too high is because it is and has always been such a non issue to shutter unneeded generating capacity.

Typically with fossil fuel plants, when the price drops below the cost of fuel for the least efficient plants they drop offline because they are no longer making a profit on fuel and the price holds. Because renewables have upfront cost to build but are free to run on a day to day basis, when there are a lot of renewables the price signal has to drop all the way to nothing before it is no longer profitable to run them.

All this means that all that happened was that for a few hours, solar production was actually enough to satisfy demand for that region. Along term, if low wholesale prices can be counted on midday then people will build industry, storage, or HVDC transfer capacity to take advantage of it.

If these prices are sustained for enough of the day that it is no longer profitable to add more solar farms, then they will stop being built in that area in favor of was to generate power at night such as wind, hydro, and pumped hydro while the panels will instead go to places that still don’t have enough solar to meet demand.

Also as an aside, the wholesale electricity market in north america is by definition about as far from a free market as it is possible for a free market to be without having exact outside price controls. It is a market built solely out of regulation that only exists at all because the government forced it to exist by making it illegal to not use it, either by making contracts off market or by transmission companies in-houseing production, or use it in any way other than as precisely prescribed by the government.

Now we can argue whether or not the wholesale electricity market is well or poorly set up or even if it should exist in the first place, but I don’t think that anyone can argue that it is a free market. At least not without defining the term free market so broad that even most of the markets in the USSR qualify as free markets.

Also, free markets and capitalism are very distinct concepts with no real relation between each other. You might argue that free markets tend to lead towards a capitalist system, but given free markets existed thousands of years before capitalism was invented I don’t think many people would say it was a very strong relationship.

But do we agree that not all devices can?

By not all you mean motors with windings connected to grid? Well, they still will work on higher frequencies, but on higher speed. Real problem is low frequency, not high. Well, 0.5kHz not all devices can handle, but most consumers(even conumer electronics, no pun intended) even rated to 50-60Hz range. So 46-64Hz should be fine for them.

What about sensitive devices keeping patients alive in hospitals?

Sensetive devices that can’t handle range bigger than ±0.4Hz? Are you kiddding me? How does that even pass certification?

Most frequency-sencetive devices are not consumers, but transformers and turbines.
