Sydney Intends To Go 100% Renewable For Electricity, Heat, & Cooling By 2030

Allan Jones, the Chief Development Officer of Energy and Climate Change for Sydney, Australia, intends to have the city rely entirely on renewable energy sources for power, heating, and cooling.

Allan, formerly the head of the UK’s climate program, was recently interviewed by the Renewables 100 Policy Institute. He commented on the ambitious nature of this program, as shown in the video below, followed by some text summary in the following sections.

Renewable Energy Sources For More Than Power

Very importantly, the initiative is to provide not only power, but also heating and cooling, using only renewable energy.

Allan Jones intends to have conventional renewables (wind and solar) generate 30% of the city’s electricity, with the other 70% coming from trigeneration (using biomass-fueled generators). Trigeneration, or combined heat, power, and cooling (CHPC) is a process in which a plant generates electricity and then uses the waste heat it produces to provide heating and cooling. The heat is used to power absorption refrigerators to provide a cooling effect.

The thought of heat-powered air conditioning sounds nice, doesn’t it?


It’s Local!

Part of the plan is to use only local renewable energy, in order to avoid transmission losses and to avoid the storm damage risk that accompanies overhead electricity transmission lines. As Diane Moss, the founding director of the Renewables 100 Policy Institute, said:

Behind the decision were several factors. Included among them was the fact that the city has little land space, so only 18% of Sydney’s renewable energy needs can be met with solar and wind power within the city boundaries. The City of Sydney also set the parameter that no remote renewables should be used, in order to avoid the energy loss and vulnerability to storm damage that come with overhead grid transmission and distribution networks.

To overcome this issue, land just outside the city will be used to generate some of the renewable energy.

Why 100%?

According to Allan, the ultimate long-term goal is to transition to renewable energy. Setting a clear and complete goal to do so, instead of just obtaining a little renewable energy here and there from a few projects, is important to them. Copenhagen is one of the few renewable energy cities Allan cited as a leading example that Sydney is looking up to.

This project will be funded primarily by the private sector. The city will fund the gas distribution line, which accounts for 10% of the budget.
