I'm genuinely struggling to see how subsidising renewable energy infrastructure is resulting in higher cost for consumers?
I have no idea exactly how that works either. I think it is probably a bit of a stretch claim on a consequence of a consequence of a consequence basis several times removed than a directly attributal effect.
But then I didn't watch cammd's video. Maybe if I did I'd find out.
But why bother ? this is Seabreeze and myscreename needs at least somebody to present nonsense opinion and not facts. So while pnl is sin-binned I am happy to step up.
Is it, that as renewables gain greater market share, the coal and gas plants will be affected. The increase in idle periods power during peak renewables supply makes it harder for these businesses? Therefore they need to charge more when there is demand
I think that is broadly true, but also the increasing downtime of the old coal plants are meaning that during times when renewables are not producing there is less capacity in the market and so the spot price rises. Most gas plants are better at ramping up and down than most coal plants, but neither have ever been designed to do so, they have been designed to run at a much more steady state than they are now required to do so.
Could a new gas plant be designed in the future to be cheaper and more efficent at providing back-up to renewables ? Dunno, maybe, I'd guess probably yes, but even then the back-up requirement is going to change quite a bit in the future so maybe not that much better.
Could batteries do it ? Theoretically yep, best things for it. Unfortunately at present the capacity they have is ****e. or less than ****e. Could a new battery in the future be better ? Good enough to backup solar and wind without anything else ? Dunno, maybe, but I doubt it. If you look at the gains over time since Tesla invented the first battery and project that forward, even with a mis-represented 'hockey-stick' polynominal projection, I wouldn't bet the lights on it.
Could the renewables provide backup to the non-renewables ? Maybe, but other than the fact that you are not then using the lowest generating cost source all the time, generally the peak demands don't occur when peak renewable generation occurs and you can never rely on renewable to be there at anytime.
