Summary
France’s Flamanville 3 nuclear reactor, its most powerful at 1,600 MW, was connected to the grid on December 21 after 17 years of construction plagued by delays and budget overruns.
The European Pressurized Reactor (EPR), designed to boost nuclear energy post-Chernobyl, is 12 years behind schedule and cost €13.2 billion, quadruple initial estimates.
President Macron hailed the launch as a key step for low-carbon energy and energy security.
Nuclear power, which supplies 60% of France’s electricity, is central to Macron’s plan for a “nuclear renaissance.”

France has old nuclear, Germany has old gas. Neither are leaders in renewables.
Yet the prior means that France is one of the least carbon intensive economies in the world. Each German unit of GDP has twice the CO2 emissions compared to France.
Germany has mostly old coal. Gas is relatively new. I totally agree that Germany needs to do more for its renewable production, like many other European countries need to do. However on a cost per energy level, renewables are beating all other production methods currently known.
