In the other day’s post we mentioned that, as of 2020, Sydney had become a fully renewable energy city. Today we have decided to delve deeper into the subject to understand the motivations that led them to make this decision and how they have made it possible.

Why do they use only renewable energy?

This decision was made by Clover Moore, a progressive mayor in office since 2004 who says: “We are in the midst of a climate emergency. If we want to reduce emissions and grow the green energy sector, all levels of government must urgently transition to renewable energy.

This is not really surprising, as she has been investing in energy efficiency changes in the city since 2016, such as the installation of solar rooftop lights and LED lights. One example of this was the replacement of 6,500 streetlights with LEDs, saving $800,000 in a single year.

What renewable energy sources do you use?

The three sources used are:

  • 120 MW Bomen solar farm at Wagga Wagga.
  • 270 MW Sapphire wind farm near Inverell.
  • 3 MW Shoalhaven Solar Farm, a not-for-profit community-owned solar scheme on the south-east coast of New South Wales.

Investment details

Renewable energy covers all of the city’s operations, including street lighting. The $60 million deal is the largest renewable energy purchase and sale agreement in the country.


It is a major investment that will save Sydney up to half a million dollars annually, as well as reducing carbon emissions by 2,000 tonnes. It is estimated that the city will have achieved a 76% reduction in carbon emissions by 2024.

This investment was a turning point for the city, which is currently investing in replacing more streetlights with LED bulbs and installing 7,800 solar panels on buildings.
