OK - at risk of providing too much information, I’ll provide a follow-up on this thread because I’ve been studying this for years now. I’ve accumulated a lot of knowledge on the subject. And, way back, a long time ago, I almost became and electrical engineer.
First thing, don’t compare EU countries with the US. They’ve got a whole bunch of materially different circumstances. Some of them political (as noted), some of them prevailing weather conditions (BTW, I’ve got a Chinese friend, former Boeing engineer, working with a Chinese company engaged in the design and sale of small wind turbines with Germany as their primary target market). But the most important difference is Europe does not have an abundance of cheap natural gas as is currently the case in the US. How long this cheap gas in the US will persist is anyone’s guess.
Gas has a lot of advantages over coal of any quality. It’s easy to move via pipelines (many of which already crisscross the nation). It’s a more efficient fuel than a coal, even in a converted coal plant, but especially in a 2nd generation gas turbine plant where the heat from burning the gas is used to drive an auxiliary generator, sort of like an afterburner. I refrain from providing percentage efficiency gains because I don’t remember the numbers, but it’s significant - however, any thermal plant is still bound by the laws of thermodynamics, they just aren’t all that efficient when compared to energy sources like hydro.
Our existing grid is pretty much 19th century technology as envisioned by Nicola Tesla (ever hear that name before?) and built by George Westinghouse who went head to head with Edison and won by promoting mostly false benefits of AC current over DC. For sure, much of the hardware has been replaced, but the underlying design has not changed all that much. There are some exceptions. In case you aren’t aware, we have built very few ultra-high voltage long-lines in recent years, but the ones that have been built are DC. There’s this little problem with AC called phase relationship. Basically, AC phase has to be perfectly matched when combining power sources or you get cancellation. One and one does not equal 2. Phase matching high voltage lines is non-trivial. It’s a problem that does not exist with DC.
But the whole notion of central large-scale generation (be it nasty, dirty coal, or those green, not nearly so benign as you might think, wind farms, solar, nuclear, etc.) with long-line distribution to several sub-stations which then step-down the voltage for distribution to the local grid is essentially the crux of the entire problem. Central, large-scale generation is not and can not be sensitive to instantaneous demand. So long as this remains the design paradigm we will forever generate and throw away a great deal of excess electrical energy.
Up until fairly recently, there was no viable alternative. Even with an alternative (described shortly) the entire utility industry is built on maintaining the 19th century design. This industry is not anxious to embrace radical design changes that would disrupt their business models and worse still, severely damage profits.
I mentioned 2nd generation gas turbines above. Another interesting thing about gas fueled generators is that they can be down-sized without losing a lot of efficiency. Also, as the generators are scaled down, the overhead associated with spin-up, spin-down is also decreased - not eliminated, but reduced quite a lot.
So, try and envision a system of local mid-scale power-plants, maybe one for each sub-station, or maybe one for a few sub-stations. Now hook them together with a smart grid so that any point in the grid with low-demand would have its power allotment shifted to areas of higher demand. The size of a “point” would have to be determined, I doubt it would be an individual home or business, maybe a neighborhood. Capacity could be instantaneously adjust to meet shifting demands. Auxiliary generators could be on “stand-by” based on historical trend data. Locally farmed electricity could be easily integrated to this system and actually put to use rather than just squandered as it is today.
OK - I’m not an electrical engineer, so I’m not going to design this system, but I can envision it. It would be almost immune to power outages by virtue of everything being multi-point connected and intelligently controlled. Yeah, maybe a small local area could still suffer a blackout, but those regional outages would be a thing of the past. But it’s true that cyber-security would be an issue.
What kind of investment would it take? I couldn’t guess. But I think we will reach a point where we will have to incrementally change the basic design of our electrical system.
