Climate change projects and studies

The people of the Illawarra have been leading the way in tackling the challenges posed by climate change. Households use 30% of all the energy consumed in NSW. This means the small, everyday changes residents of the Illawarra are undertaking to increase the energy efficiency of their homes and cut their greenhouse gas emissions, can collectively have a big impact in creating more sustainable futures.

Embodied Energy

Though it’s important to look at the energy we use in our homes, looking at the bigger picture, most of our energy usage is hidden in the production and distribution of all the goods and services we consume.

Embodied energy refers to the total amount of energy that goes into making something – including extracting the raw materials, transportation, assembling the product and the disassembling and decomposition of the product after it’s finished with. The Australian Conservation Foundation has put together a really helpful tool at that shows the environmental cost of our consumption in terms of greenhouse gases, water and eco-footprint.

Of all the things we consume, surprisingly, it’s our food which has the most hidden energy input. Cooking healthy food from scratch, purchasing from local and sustainable food producers, and having a go at growing food in your own backyard are everyday actions we can take to address climate change, which are just as important as reducing household energy bills.

Renewable Energy Certificates (RECs)

What is a REC?

Renewable Energy Certificates are a form of currency which recognises and certifies that renewable energy generation has taken place.

The REC system has been created to aid in meeting Mandatory Renewable Energy Targets (MRET), set to reduce Australia’s greenhouse gas production and increase the proportion of Australia’s electricity that is derived from renewable energy sources.

Each REC represents an equivalent 1 megawatt hour of electricity generation from an accredited renewable energy source, or in the case of solar hot water heaters each REC represents the equivalent of 1 megawatt hour of electricity displaced by solar energy.

Eligible technologies that may be able to create RECs include:

  • Solar hot water heaters
  • Heat pump hot water heaters
  • Small photovoltaic solar energy generation systems
  • Small wind turbines
  • Small hydro systems

Each system is assigned a REC value which represents the number of megawatt hours displaced by the system over its lifetime. The value of 1 REC at the time of purchasing the system will determine the total REC value of the system.  For example if your solar hot water system is entitled to 24 RECs, and the value of 1 REC is $46.00, then the total REC value of the system is $1,104.00.

In addition to rebates, there is also the opportunity to receive a further cost reduction at the time of purchasing climate friendly technologies like solar hot water and solar power systems through the creation of RECs.  Owners of solar hot water heaters or solar power systems can create RECs themselves through the Office of the Renewable Energy Regulator’s internet based REC registry and do not have to sell them. However, most people find it far more convenient and simple to assign their right to create RECs to a Registered Agent in return for a financial benefit such as a discount at the time of purchase.

For more information on REC’s check out the Clean Energy Regulator or speak to your solar hot water or solar power supplier.
