The Paris climate goals commit the world to get to net zero. But what will the global energy system in net zero look like? Will renewables be the dominant source of energy? Will there be any role for oil and natural gas? How important will emerging technologies and energy carriers, such as CCUS and hydrogen, be? This talk will use the scenarios included in the 2019 IPCC report to try to get a sense of what we do (and don’t) know about the global energy system in net zero.
