"Materials used by weight"

"There was a slight reduction in coal and gas use in FY2014 due to reduced electricity generation at AGL's thermal generation sites including AGL Loy Yang and AGL Torrens."

"Material (kt)",FY2013,FY2014,FY2015
"Brown coal","19,349","19,121",
"Natural gas",520,438,

Notes
"These figures include facilities over which AGL had operational control during the period, regardless of who owns the asset. Assets where AGL controls or has rights to the electricity output only are not included, nor are AGL's non-operated Upstream Gas joint ventures."
"Only brown coal and natural gas are included in the table, as they represent the two major materials consumed across AGL's portfolio. Smaller quantities of other fuels are also consumed across the portfolio. The consumption of these fuels is detailed in the energy consumption section of the data centre. The use of steel, concrete and other materials has been assessed as immaterial compared to fuel combustion, particularly as many construction activities are outside of AGL's operational control."
"Only the combustion of natural gas has been included. Quantities of vented natural gas are available in the vented and flared hydrocarbons section of the data centre."
"Figures have been rounded to the nearest kilotonne."
