A brave prediction sir.

Hydro has been with us for a long time. You can make many complaints about its environmental impact and the good sites are already taken, but there is no escaping that it works. It is usually a lot cheaper than coal or nuclear and can be classified as baseload. Also as mentioned in the article, it has by orders of magnitude the fastest cold boot times of any current baseload.

I can completely understand that solar has a somewhat limited benefit in the UK but in other parts of the world we even get sun from time to time.

The price of solar has dropped by orders of magnitude over the past decade. That trend is only going one way. The question longer term isn't whether some baseline can be replaced but rather how much is needed to maintain reliability. With pumped storage as illustrated here, that number can go much further north. Remember that solar doesn't require ongoing fuel costs so there will be a running cost advantage. Once those graphs cross over, it will be nigh impossible to get funding for new projects.

Another important point is that not all demand is inelastic. We just haven't had the levers to discourage behaviour in real time until recently. Whilst lighting, cooking, air con or heating and of course warm beverages are a given, much industrial uses like smelters can be paid to partially shutdown for peak periods.

Time of use "smart meters" are a longer term demand management opportunity. Each EV has a battery pack between about 10 and 60 kWh which again in a longer term can handle fluctuations.

Whilst it isn't all going to change tomorrow, the writing is on the wall.
