● The magnitude of the change required in the global energy system will be huge
● The challenge is to find a way forward that addresses simultaneously climate change, security, equity and economics issues.
● Paradigm change is needed: radical improvements in energy end-use efficiency, new renewables, advanced nuclear and carbon capture and storage.
● Needs to be globally integrated but with maximum support of countries and local levels.
● In the best spirit of science: fact-based and peer-reviewed
