Indeed. And in my view if we have enough battery farms at solar and wind farms then we don't need a constant baseload but an adaptable one for peak times. Emission free combustion engines using hydrogen for example are currently being developed and could be an answer.

Why go through the complexities of hydrogen power whether it’s blue, grey or green when there are already synthetic fuels with zero emissions using the already abundant CO2
It went from £20000/l to £4000/l in 8 months, by that trajectory, in another 54 months it can go down to £2/l, now that’s worth holding thumbs for

You really clutch at negative straws. Sorry to be rude, but I'm seeing why some won't debate with you seriously.

Show me how you can state as some sort of "fact" that it's unattainable.

No man, it's current thinking which usually won't survive future thinking in tech.
Maybe too much of an ear on MSM..

Nice argument. Just going to mention that synthetic can't hold a candle to natural for widest long term benefits. Pun unintended. Not that I've come across anyway.
 
The country has endless unused mines that could be converted to pumped storage facilities to cater for the the periods when solar/wind generation capacity is not available.

Synthetic can cater for demand, renewables will never be able to cater for demand
Therein lies the problem and solution

You need to generate base load. Whether it be from fossil fuels or nuclear you cannot power a country without base load.

When the sun isn't shining and the wind isn't blowing you need base load to carry you through.

At the moment the vast majority of our base load is generated by burning fossil fuels. Without a move towards nuclear generation, this won't change.

Hydrothermal.
 
What about this:

Base load: Nuclear

Rest: Renewables

How feasible would something like this be?

What would the other renewables do? Nuclear power stations can do operational flexibility like coal stations.
So they can run at their capacity plate or lower to meet the needs.
So if you've got enough nuclear to cover your peak demand with 4GW leeway what would the other renewables?
 
None of the above, South Africa has an endless untapped resource that everyone keeps forgetting. What about Waste-to-energy? The ANC is so full of **** we could use them to power the planet 10x over
 
Its simple Common Sense:
1-At a scale of 3 Billion humans on planet you can do a lot to make life good for all. Because theres enough resources most choices can work as suggested.
2-At a scale of 7 Billion plus, its a complete other story. Now we enter the stage where the Earth does not have enough resources enough to promise 7 Billion plus they going to have a reasonable life, let alone a good life=The last 30 years since 1992 has proven that already for all to see. Only the Ultra Rich and the Upper Corrupt has good lives, the rest suffer in stages.

The thing is Electricity is as we live today a Basic Resource(Man Made), like Water, Oil, etc. Now since 1992 "Digita:" has come along, hopelessly opertunistic, overvalued Fools Paradise, jacking up the cost and waste of resources hugely, we going to pay dearly for that mistake.

If basic resources are relatively expensive, it effect everything upwards and chew into and destrot monetary systems from the inside out. The human race NEVER experienced this before in history, there were aklways less humans chasing for resources in a closed system like Planet Earth, therefore the ignorance.

Renewables are based from Weather conditions, Day/Night, and its not centralised, meaning huge duplication of resources, also it may be cheaply presented and promised initially, but whos going to maintain it after a few years and at what costs, and how difficult to keep up a standard with it spreaded all over the place(Physical Polution we not seen before either). These structures will change hands as they get shook off by initial installers like 2nd hand vehicles for others to put up with the problems, and on top of that our new god "Digital & Internet" is totally dependant on good stable power supplies right through from AC to DC, and thats where your money is going to rely from in future....Big problem.

Renewables are good under certain selective circuimstances, but carrying the whole globe, I think that is a pipe dream playing out.

Energy is not the place to play with, and so is water and oil.
