It means that it's impossible to earn money in France ?

Don't expect to earn money (not even ROI) with inefficient (outdated) hardware, and especially in places where the electricity is that expensive. I had access to 0.08 USD per 1KW and even with that price it would not be profitable to mine with that device. Mining as a hobby is not possible anymore unless you want to slowly lose money over time.
