We are moving our energy systems at pace from a relatively narrow and widely adopted technology base to one of broad based and distributed design, where resilience and dependability is achieved by adopting a more complex systems-based approach, utilising new technology that will continue to evolve as we go through the Energy Transition. In equal measure, success will also depend on societal willingness to embrace the new future as many facets of our lives from the way we heat our homes and use transportation to how we interact with the natural environment will change manifestly.
