France has long taken pride in its low-carbon intensive energy sector, which relies on nuclear power by up to 75% and natural gas. As the aging infrastructure requires upgrading, the decision to allocate future investments leaves much room for heated debate. Now, a controversial report from ADEME (French Agency for Environment and Energy Management) which was recently published after media leaks exposed it, may shake up the whole house. Its research shows that a 100% renewable power system in France is both possible and economically attractive, as the cost of wind and solar continues to fall, and the cost of natural gas including CO2 is expected to rise steadily, while nuclear is becoming more expensive primarily due to the new safety regulations. Yet another indication that the energy tipping point in favor of green power has been reached.
