The City of Sydney has prepared a Decentralised Energy Masterplan towards their aim of becoming 100% zero carbon by 2030. The plan makes a careful analysis of how energy is currently used in the city and maps land use together with gas and electricity use to identify the most intense areas of carbon emissions. These areas are then zoned for the introduction of low carbon infrastructure. In Sydney this means bringing Trigeneration closer to areas of demand. Rather than generating power remotely using coal Trigeneration generates electricity locally from gas, reducing energy lost in transmission and using the waste heat produced productively for heating or cooling.
