The LCOE of solar/wind is the cheapest but it does not seem to be common knowledge. The lack of common knowledge often is some kind of polarised political beliefs, from what I've seen
Marginal pricing seems to be a large part of the problem when the general public do not see the benefit of this green revolution that's been going a long time.
In the UK part of the payment is for social/environmental factors. It's about time the state awarded people that have already done that instead of paying marginal prices.
LCOE is only fair with storage taken into account, which is hard because storage does not necessarily exist in capacities to make a comparison with non intermittent sources relevant.
The joke is that the LCOE of solar is "Infinity / kWh" at night if the battery is empty, "-Infinity / kWh" at noon if the reservoir is full, and "NaN / kWh" when there is not enough câbles.
That being said, the answer to "which carbon -light electricity source should we build ?" is "YES".
I, too, long for the days where we have batteries massive enough to not even care any more.
This was true a couple of years ago.
This is no longer true.
Storage has become a lot cheaper very rapidly. The LCOE of solar with storage covering the night is now competitive.
Not entirely sure: everywhere I read about solar + storage, there are huge errors bars. Eg : https://www.lazard.com/media/eijnqja3/lazards-lcoeplus-june-...
Solar+storage : from 50$/MWh to... 131$/MWh !
Go make a decision with something like that.
The trend is clear, for sure, and it will make sense to extrapolate... Up to a point, as usual. (baring one of the "breakthroughs" that make it to the HN top page on e in a while and never materialize... Sigh)
Night, sure. Doesn't work in winter though. (Not that that means we should stop building solar - we're still far from the point where it wouldn't make sense to build any more solar because we can't store the energy.)
