The grid edge revolution - Innovative drivers towards net-zero energy
We show how innovations at the grid edge are helping to drive one of the most radical transitions in human history – a move from a centralized energy system to one that is more decentralized, more local and more efficient. Towards an energy system that is more democratic and where individuals have more control. An energy system that meets the needs of the global population, but that also benefits the planet.
