Limiting the global average temperature rise to 1.5-degrees-C will require all sectors of the economy to reach zero carbon dioxide (CO2) emissions early in the second half of this century. A growing number of countries are committing to such net-zero-emission goals. There is general agreement that renewable energy and energy efficiency are the cornerstones of the energy transition and that renewable energy will provide the bulk of clean electricity in the decades to come.
The optimum trajectories, however, for the end-use sectors of buildings, transport and industry are less clear. That was the topic being explored in the International Renewable Energy Agency’s (IRENA) Innovation Week 2020 in the context of the agency’s role as the global energy transition accelerator.
