My point is to not build new nuclear centrals. France should maintain its current centrals so that no coal is used and as little natural gas as possible.
Recycling solar panels (and other stuff used to produce renewable energies) is a real issue. But I wonder why pronuclear fanatics are so sure that we will find technical solutions to dismantle old nuclear centrals and safety stock tens of thousand tons of nuclear waste... but always point the issues and challenges of renewable energies as totally impossible to get over.
Nuclear energy is not the solution for a sustainable world. So France should invest heavily in research and development on renewables energies to find solutions that scale to the needs of 9+ billions people.
There are plenty of discoveries and breakthroughs to make, patents to deposit so that France can reindustrialize and have an positive industrial balance in 20 years.
At the same time, nuclear fission should be pursued. It will cost tens of billions but that's worth it. The EU ought to keep up with China and the US leading that field. The ITER project is international but is getting behind.
