Electricity is the only energy that offers the fastest vector for decarbonisation through the combination of renewables and digital solutions. Smart bi-directional grids are the only way to enable the energy transition, helping the world halve its emissions by 2030 and reach net zero by 2050 to keep within the 1.5C warming trajectory. The ‘grids of the future’ enable this by allowing multiple sources of locally generated decentralised renewable energy to combine safely and reliably while delivering resilience.
