Abstract:

The objective of this report is to gather opinions about the feasibility of a 100% renewable energy future, and the macro-economic impacts it would entail. In so doing, the report reflects on the debates of 2013, and tracks their evolution to the present time. Some remain, some have changed, some have been overtaken by progress, and new ones have arisen. They are summarised here as the Great Debates in renewable energy. This report presents views of 114 renowned energy experts from around the world, on the feasibility and challenges of achieving a 100% renewable energy future. Their thoughts are grouped into 12 Great Debates ranging from the future of heating and transport, the interconnection of sectors, the role of mega-cities and what utilities of the future could look like.
