© OECD/IEA 2013 Biomass: energy vs. non-energy Only Energy purposes Biomass is included Non-energy use of biomass is excluded
© OECD/IEA 2013 Table 2: Reporting Liquid biofuels Report only the quantities of liquid biofuels and not the total volume of liquids into which the biofuels may be blended. Used directly as fuel, not included in biogasoline or biodiesel For blending to Motor gasoline/diesel
© OECD/IEA 2013 Production vs. capacity: consistency We can check the utilization rates of plants with production and capacity figures. Net electricity production Utilization rate = capacity * time Example : Wind electrical capacity = 28 MW Net annual electricity production = MWh Utilization rate = = MWh/(28MW * 24 h/d * 365 d/y) = 18%
