Transition to low carbon power systems is a key present issue. It takes part from a higher purpose, which is to stabilize greenhouse gases concentrations in the atmosphere while making economic and sustainable development possible.
In its last fifth report, International Panel on Climate Change assessed options for policymakers to mitigate climate change. They argue that decarbonizing electricity will be a major component of mitigation strategies, and give some prospective. As they do I’m convinced that magic remedy does not exist, and that we will have to make some well-balanced choices, based on cost-benefit and cost-efficient analyses. Will we able to increase the nuclear energy share considering operational risks, yet unresolved waste management issues or adverse public opinions? Will we be able to adapt our power networks and markets, our electricity demand and capacities to the growing renewable energy share? Most of OECD countries are facing a low growth rate and have spending limits. That makes choices that will be done so important.
