I am considering using more accurate (ie non-0) kgCO2e/kWh (lifetime amortised) #emissionsFactors for some #GB #FUELINST low-carbon #electricity #generation sources, eg #NPSHYD (hydro), #NUCLEAR, #WIND, in the EOU live #carbonIntensity calculator.

Is there a definitive source, or would (say) WIND=0.01, HYDRO=0.02 NUCLEAR=0.01 be a reasonable start?
