Carbon calculations – To estimate how much carbon your share of the project could save from entering the atmosphere, we used an estimated 1,206 MWh annual energy output from the project, alongside a 0.16kgCO2/kWh past 5 year average for the carbon intensity of the National Grid, and an estimated carbon footprint of onshore wind of 8g CO2eq/kWh to consider emissions from Fan #1. To work out how many homes could be powered by the project, we used an estimated 2700kWh of annual electricity consumption per home. Please note these figures are estimates and should not be taken as fact or relied upon.
