Without any consideration for I/O? In my experience performance is often directly related to the ratio (total RAM available to Postgresql, shared buffer and buffercache included / total size of tables and indices ), save any weird

You wrote "bottlenecks", I showed that we deploy more and more. The reader can decide. You first criticize me for merely providing data, then for my "analysis". Go figure. Your points (substitution effect and methane)

It implies an adequate design, adapting (retrofit) an existing nuclear plant to such co-generation is very difficult.

Renewables did compensate nuclear's underproduction: without them France would have burnt more fossil fuels. Moreover ~60% of France's final energy is obtained by burning fossil fuels => France must electrify (replace fossil fu

In Germany the problem is coal (lignite): it remains a huge social and political 'asset'. Many jobs, low-priced electricity, no dependency towards fuel shipped by a foreign nation... France switched to nuclear because at the time
