More mains outages with renewable energy?
« on: July 04, 2021, 08:29:15 pm »
Will there be more mains outages when our power grids are  supplied almost exlusively by wind and solar? (as they soon will be).
I believe we will see regular daily outages. Would you agree? (even if only for 20 seconds each day)

That might depend on whether the power grid is connected to sources outside of your State (US reference).
Since solar power has a diurnal variation, storage might be a good idea.

“Exlusively” is an interesting Freudian typo in his original post

Can we get regular 24-hour outages for treez's house?

I don't think short power outages would be a real issue. Mainly wind and solar would need quite some storage and than short outages would be less of a problem. The point is more like unusual weather patterns depleting the storage capacity, like a low wind winter, or severe weather in general. More frequent extreme weather is expected anyway - with solar and without.

I don't hink rolling blackouts are very effective. Many of the high power uses (like heating / cooling, car charaging) have some storrage capability and would take a similar energy, just a few hours later.

Provide incentives to adapt demand to supply and a big part of the problem will solve itself. That is, make energy more expensive when supply is low and cheaper when there's a surplus. Also make the energy cost progressive during high demand so that those who use a lot would have to pay a lot more, but only running essential stuff would remain cheap.

How do you even function on a daily basis with such bitterness and paranoia?

Like California and Hawaii, I doubt enough storage capacity will be provided once politicians see the cost.  And there are considerable rents to be collected through rationing.  ISPs, at least US ones, do it so why not power companies?

Also make the energy cost progressive during high demand so that those who use a lot would have to pay a lot more, but only running essential stuff would remain cheap.

That would be my preferred solution based on economics however it itself could produce grid instability, and of course the rents issue mentioned above may make it infeasible politically.  That is why we have cap and trade.

No. It's a manifestly obvious problem and the reason why renewables are always talked about in tandem with energy storage systems.  Whether battery, pumped, molten salt or etc.

Dirt cheap thermal storage is a perfect match for HVAC and hot water, two big residential loads.

I used California and Hawaii as specific real examples where storage was deliberately ignored.  Real Engineering covered it a couple years ago:

Recently I have been watching TIK's videos discussing economics during World War 2 which have lead me to think more and more of politics as being the art of replacing and ignoring the science of economics.

Yes, cautionary tales of ignoring the obvious.  Another thing politics is good at...

On a fundamental level, politics is about determining the distribution of scare resources.  Mind, that distribution need not be particularly "fit", for a given definition of "fitness" and "organism".  (Evolutionarily speaking, villages of up to ~150 individuals would be the superorganism whose fitness matters.  Presumably, that explains the ~1% rate of sociopathic/NPD or related traits in the population; their natural interest in leadership makes their survival contingent on survival of the group, but they needn't be particularly concerned with the survival of any given individual within that group.)

Applied today however, there are several segments with little or no scarcity.  There is more than enough food to feed everyone, if we wanted to.  Or spare budget to cover it, if we wish to preserve the market based economy that drives it today.  But politics always finds a way.  If scarcity doesn't exist, it will be invented, and so we have food waste simultaneous with starving poor.  Or for another example, all the marketing tactics employed to justify the pricing of video games, which are distributed digitally nearly for free.  Anywhere there is a buck to be made, it (apparently) must be, and anywhere there's a lot of bucks to be made, economics gives way to politics, and everyone involved (and everyone wants to get involved) wants their kickback.  Big-economy projects are a notorious case; the history (or more accurately, lack thereof) of high-speed rail in the US is a prime example.
