Energy in Your Home or Business

Electricity and gas are part of the critical infrastructure that supports our lifestyles. It is a significant part of household and business budgets and has got more expensive due to the changing international energy security landscape. To provide equitable access to energy the Federal Government have launched the free Energy Made Easy website, which can be used to find and compare home and small business electricity and gas plans.

Another important way to reduce your energy bills is to reduce energy use. No matter what your budget, you can make considerable energy savings by following a few simple energy efficiency ideas and suggestions.

Energy efficiency simply means using less energy to provide the same service or achieve the same result. It's about doing things smarter, or with improved technology.

You can find some useful information on the following pages to help you make the choice that best suits your needs

Hot Water Systems

It is worth considering what would be the right hot water system for your needs to gain full financial benefit and system efficiency for your area.

Water heating can account for more than one third of a households energy use, therefore there is a significant saving to be made in running cost.

The two most energy efficient types of water heating available on the market are:

  • Heat pumps
  • Solar

Further Information

Both the state and federal government have useful websites to help you decide which hot water system will best suit your household.

Energy Efficiency

Australians are becoming more energy efficient in general. There are some great tips to help you to become more energy efficient in your home or business;

  • Every degree you move your air-conditioner temperature closer to the temperature it is outside, you will save approximately 10% on your air-conditioners running costs.
  • Insulation can save up to 45% on heating & cooling. Air conditioning will be more efficient with insulation installed.
  • Drafts can increase your heating costs by up to 25%!
  • In winter windows can allow up to 40% of heat to leak out. Heat gain through an unshaded window in summer can be 100 times greater than through the same area of insulated wall.

Renewable Energy 

Renewable energy comes from a number of sources such as the sun, wind, the earth's heat and ocean systems. The endless supply of these types of renewable energy makes them very sustainable and environmentally friendly.

Wingecarribee Shire Council actively promotes and supports local sources of renewable energy. Council has embarked on a range of energy initiatives for its operations and services here in the Southern Highlands.

Qualifying solar hot water, solar/wind power systems or solar panels currently attract government financial support in the form of Renewable Energy Certificates, known as RECs. 

Solar for Low Income Households

The Solar for Low Income Households offer helps eligible households access affordable clean energy by providing them with free solar systems. A solar system can help you unlock long term savings on your household electricity bills by up to $600 a year. 

Over the next 12 months, the offer is expanding across NSW.   This offer helps homeowners on low incomes reduce their electricity bills by installing 3 kilowatt solar systems on their homes. Solar is a great way to reduce your environmental footprint and you can save up to $600 a year on your household electricity bills. That’s up to twice as much as the Low Income Household Rebate of $285 a year. 

Solar Power

Solar panels that generate electricity are known as photo voltaic (PV) systems. Here are some tips to think about when considering the type of solar system that suits your needs at home or for your business:

  • Speak to a solar industry expert.  Solar technology is rapidly developing so be sure you have the most up-to-date, proven options available to choose from.
  • Lower your energy use as much as you are comfortable with, to help reduce the size of the solar system you will need.
  • Consider how you can maximise exposure of solar panels at your property including:

     - The direction your roof faces 

     - The angle of the roof 

     - Shading from nearby trees or buildings

Hot Water from Renewable Energy

Solar Hot Water systems heat water through solar panels or evacuated solar tubes on rooftops or buildings. The heated water is then piped around the home or commercial buildings ready for use. Read more on our Hot Water Systems page.

This solar hot water can also be used to heat flooring by running water pipes inside concrete floor slabs during construction. The Moss Vale War Memorial Aquatic Centre uses a solar hydronics system to heat both pool water (together with heat pumps), some pool walls and surrounding concrete floors for the warm comfort of pool users.

Heat pumps are also used to heat household water using renewable energy. Heat in the outside air is transferred into water inside the heat pump through a heat exchange system.

There are three large scale wind farms in fairly close proximity to the Southern Highlands:

Capital Wind Farm near Bungendore and Woodlawn Wind Farm (provides enough renewable energy to approximately 23,000 homes), together generate 140.7 megawatts of power.

Taralga Wind Farm is another nearby large scale wind generation facility. The wind farm’s 51 turbines generate up to a total capacity of 107MW of clean renewable energy for the life of the project.

Small scale wind turbines for individual homes can also be found generating renewable energy around the Southern Highlands.

Wind Energy


NSW has 36 hydro electric plants, with the largest in the state being The Snowy Hydro Electric Scheme.

The Shoalhaven Scheme is the closest hydro system to the Southern Highlands.  Water pumped from the Shoalhaven Scheme is mostly collected from the Tallowa Dam catchment of 5,750 square kilometres. Wingecarribee and Fitzroy Falls reservoirs have relatively small catchment areas totalling only 70 square kilometres. Power generation involves regular exchange of stored waters between Lake Yarrunga, Bendeela Pondage and Fitzroy Falls Reservoir.

Small scale hydro electric systems generally don't require dams, instead relying on flowing streams and privately owned waterways. Some small scale hydro systems are being considered for irrigation structures and weirs, and investigations are underway to understand possible environmental impacts of developing these systems.

This technology is just starting to develop in Australia, making up only 0.001% of the country's total clean energy generation Clean Energy Council. One geothermal plant that is operational is Ergon Energy's 0.12 MW facility at Birdsville in Queensland.

Ocean Energy

Ocean energy is classified as tidal energy, wave energy and ocean thermal energy. 

A wave energy trial has started at the Perth Wave Energy Project site off Garden Island. It is the only grid connected project in the world currently using this particular wave energy technology called CETO, named after an ancient Greek sea goddess (also known as Keto). The project also includes construction of a desalination plant that will be run by CETO wave energy - another world first.
