How to read the figures:
Left-top: % Share of fuel input (TJ) by type (liquid, solid, gaseous, biomass and other fuels) into 1A1a public electricity and heat production.

Left-bottom: Implied emission factor for each fuel above (tCO2 / TJ), taken from EEA (2009)

Right-top: Average efficiency of transformation in EU-27.
Numerator = 101109 Output from district heating plants + 101121 Output from public thermal power stations
Denominator = 101009 Input to district heating plants + 101021 Input to public thermal power stations

Right-bottom: % Share of CO2 emissions by fuel type (liquid, solid, gaseous, biomass and other fuels into 1A1a public electricity and heat production)
