Power grid sees ‘greenest ever’ moment

Great Britain’s power grid saw its “greenest ever” moment on Easter Monday as low demand over the holiday weekend, combined with sunny spells and strong winds, allowed renewables to dominate the energy mix. National Grid Electricity System Operator said the carbon intensity of the power grid dropped to a new record low of 39gCO2/kWh at 1pm, with zero carbon sources providing nearly four fifths of electricity.
