The way we produce and use energy is changing – from large-scale infrastructure and system changes (e.g. renewables, hydrogen) to new technologies in our homes (e.g. heat pumps, energy storage). A successful green energy transition therefore requires support from the public – developers need a social license to operate, and householders need to buy and adopt new technologies. This talk will cover what we know about public acceptance of energy technologies and future energy systems. Christina will also discuss why early and meaningful public engagement can be an effective way to ensure publics are involved in decision processes and lead to better and fairer energy transitions.
