Energy

In this section, learn about what the City of Kalgoorlie-Boulder is doing to reduce it's energy consumption, and what you can do at home to reduce yours!

What Can You Do At Home?

What Can You Do At Home?


Lighting

New ultra-low efficient LED lights are now available to purchase for your home from supermarkets and hardware stores. These can plug directly into existing light sockets and can save over 50% of electricity consumption compared to current energy efficient Compact Fluorescent Lamps (CFLs). These lights could save you up to $150 each year if you replaced all the CFLs in your house with LEDs.

Don't Overheat or Overcool Your Home

Cooling your home to 23 degrees in summer and heating it to 19 degrees in winter will save you considerable amounts of money and electricity. Every degree above 19 degrees in winter and every degree below 23 degrees in summer can add up to 10% to the running cost of your heater/air conditioner.

Energy Efficient Appliances

The Energy Rating System for electrical appliances provides an easy to understand guide to purchasing energy efficient appliances for your home. Each appliance has a ‘star rating’ ranging from one to six stars, with the most energy efficient options achieving a six star rating. By following this guide, you can save a significant amount of electricity as well money over the life of your new appliance.

Install Solar PV 

Solar photovoltaic systems can heavily reduce your consumption of electricity from the grid, saving a significant amount of carbon emissions as well as substantially reducing your power bill. A 1.5kW system can reduce your consumption of grid electricity by up to 40%.

Install insulation in your home 

If your home does not have insulation, this will be costing you significantly. Installing insulation can save up to 45-55% on your heating and cooling costs. Uninsulated ceilings, walls and floors can account for 70% of total heat loss from a home.

Turn Appliances Off at the Wall

When appliances such as computers, TVs, printers and stereo systems are turned off with the ‘On/Off’ switch provided, they merely enter ‘Standby Mode’. This means they are still consuming electricity and costing you money on your power bill. To eliminate this unnecessary consumption and reduce the size of your power bill, turn these appliances off at the wall instead. This could save you up to 10% of your electricity costs.
 

Solar PV Systems

The City of Kalgoorlie-Boulder has recently increased its green credentials substantially with the installation of three significant solar photovoltaic (PV) systems. These systems were installed on sites that consume considerable amounts of electricity and are designed to reduce the City’s overall electricity consumption as well as its greenhouse gas emissions that contribute to climate change.


Community Centre 17.5kW system

CKB Community Centre Solar PV System

To view the amount of energy this system is producing in real time: click here

  • This system will save approximately 28,000kWh of electricity consumption each year which is the equivalent of the annual electricity usage of 4.3 average homes
  • It will also reduce the City’s CO2 emissions by 22 tonnes every year, the equivalent of taking 4 passenger vehicles off the road permanently

  • The City will also save over $7,000 a year in electricity costs
     

Administration Building 30kW system

  • This system will save approximately 50,000kWh of electricity consumption each year which is the equivalent of the annual electricity usage of 7.6 average homes

  • It will also reduce the City’s CO2 emissions by 39 tonnes every year, the equivalent of taking 7 passenger vehicles off the road permanently
  • The City will also save over $13,000 a year in electricity costs

Oasis Recreation Centre 135kW system

  • This system will save approximately 246,000kWh of electricity consumption each year which is the equivalent of the annual electricity usage of 37.4 average homes
  • It will also reduce the City’s CO2 emissions by 192 tonnes every year, the equivalent of taking 36 passenger vehicles off the road permanently
  • The City will also save over $54,000 a year in electricity costs
  • The Oasis Solar PV Project receives funding through the Low Energy Emissions Development (LEED) Fund, administered by the Department of Environment and Conservation.

Wastewater Treatment Plant 150kW System




In August 2014, the City completed works on the largest council-owned solar PV system in WA. The 150kW system will produce 15% of the wastewater treatment plant's energy requirements and save the City over $60,000 each year in electricity costs.

In total, the City’s four solar PV systems will save the City approximately 584,000kWh a year of electricity consumption (61 average homes), reduce the City’s CO2 emissions by 440 tonnes a year (103 passenger vehicles) and save the City over $128,000 a year in electricity costs.

 

Oasis Recreation Centre Alternative Energy Project

As part of the City of Kalgoorlie-Boulder’s ongoing commitment to sustainability, the Oasis Recreation Centre has undergone a green energy transformation. With the help of federal and state government funding, CKB has installed a solar PV system and a solar thermal system on the Oasis roof, and a ground source heat pump system underground. These together will offset 8,309 GJ of natural gas and 206,000 kWh of electricity per year that would otherwise be used to warm the pools and heat and cool the centre. The savings in natural gas consumption translates to monetary savings of nearly $260,000 a year. This will reduce CKB’s CO2 emissions by over 500 tonnes a year which is the equivalent of offsetting the electricity use of 75 average households, taking 104 passenger vehicles off the road permanently or planting 13,000 trees and growing them for 10 years.

The Oasis Alternate Energy Project received funding through the Federal Government's Community Energy Efficiency Program, administered by the Department of Industry.
