Sustainable Energy Projects

As part of the City’s commitment to an Energy Wise City, we are working hard to improve the energy performance of our buildings. This includes delivering a program of energy efficiency projects, installing solar energy systems, carrying out building energy audits, improving the monitoring of building energy consumption, incorporating Environmentally Sustainable Design (ESD) requirements in City building projects, and carrying out energy education activities.
The program of sustainable energy projects has included the installation of LED lighting, more efficient air-conditioning equipment, solar photovoltaic (PV) systems and solar water heaters. These projects are reducing energy consumption and costs in the City’s buildings, increasing the City’s clean energy capacity and reducing the City’s greenhouse gas emissions.

Energy Efficiency

The City was the successful recipient of funding from the Australian Government to deliver community energy efficiency education programs and undertake energy efficiency upgrades to four major facilities: Terry Tyzack Aquatic Centre, Leisurepark Balga, Works Depot and Mirrabooka Library.  Solar PV system on the roof of Herb Graham Recreation Centre, Mirrabooka

City-wide Energy and Emissions

The energy that powers the City's operations and services comes from both non-renewable supplies (such as coal-fired electricity, gas and fuel) and renewable sources (such as solar powered electricity and solar thermal heat). Taking all energy sources into account, there has been a 2% reduction in total energy consumption over the past five years. Energy consumption of gas went up by 7%, electricity reduced by 4%, and fuel consumption reduced by 2%.

In 2014/15, the City emitted 26,167 tonnes of greenhouse gas emissions. This represents a 10% reduction over five years, taking into account
offsets. In previous years, the City purchased green power and bought carbon offsets. However, these funds are now being channelled into energy efficiency retrofits and renewable energy projects that directly reduce emissions.

The three largest greenhouse gas contributions to the City's total emissions in 2014/15 were from the following asset categories;

  • Facilities/parks (44%)
  • Street lights (39%), and
  • Fleet vehicles (17%).

Over the past 5 years, there have been greenhouse gas emissions reductions from all major asset categories; streetlights 13% decrease, facilities and parks 11% decrease and fleet vehicles 1% decrease.

Streetlights are currently classified as supply chain emissions, as 98.8% of the streetlights in Stirling boundaries are owned and managed by
Western Power but paid for by the City. Accordingly, the City is unable to easily replace inefficient streetlight globes with more efficient LED globes. Given that streetlights form 39% of the City's emissions, this represents a significant challenge. However, energy efficient LED streetlights have been included in several City owned developments and subdivisions.
