This is the UK electricity grid predicted (blue) vs actual (orange) carbon intensity gCO2/kWh. So we had a bit of a storm last night resulting in a very low carbon intensity, dropping to 80gCO2/kWh in this example. This was perfectly aligned with my cheap rate time period 12:30am - 4:30pm night time electricity 12p/kWh. So I’m charging the #EVs running the dishwasher and mining 🌽 all on mostly wind power ! 🎸
