Green Electricity

  1. How do I know what I am getting and how much it costs with Green Power?

    Green Power Choices – Confused want to know who to trust

    Check out Green Electricity Watch

     for an independent review of what is at offer and a rating score of how the company fares.

    For Example

    • AGL Green Energy; This product is 100% GreenPower and Scores 52 out of 100.

    You pay 5.5 cents for each unit of GreenPower.

    • GreenEarth Wind Energy Origin: This product is 100% GreenPower and scores 76 out of 100. You pay 5.5 cents for each unit of GreenPower product is 100% GreenPower.

    Based on average electricity use, this will cost you $7.22 per week on top of your normal electricity charge.

Carbon Footprints

  1. How do I calculate my carbon footprint?

    There are many carbon footprint calculators on the internet and they all use different methods of calculation

    Here are a couple.

    Ecological footprint calculator


    Australian Conservation Foundation

    Look here for the consumption atlas. 

    How does Mt Gambier compare to the State and to national average on Ecofootprint, Water Use and Greenhouse pollution.  Go here to find out


    Have you been to the 1million woman website - especially designed for women?


  2. How much greenhouse gases does the average person in Mt Gambier produce each year?

    Recently a small group of us did the CSIRO EnergyMark program and through this we worked out our Carbon Footprints.

    The numbers ranged per person from 9 tonnes of CO2 a year to 15 Tonnes of CO2 a year.


    The challenge is to reduce this.

    The Australian Conservation Foundation Consumption Atlas states that the average person in Mt Gambier produces 16.17 tonnes of CO2 a year.

    Is this good?

    Australians have the 4th highest ecofootprints in the world.

  3. How can I save money on my transport costs?

    Register on the Better Harts website and learn how to reduce your transport costs. Enter your savings each month and help to reduce our carbon CO2 emissions.

  4. I would like to share the drive to Adelaide?

    Register your trip on the new website and find someone to travel with or find a trip already going to Adelaide.

    Great way to meet new friends.

Energy Audits

  1. How do I save money on my electricity and water bill?

    - Contact CAS on [email protected] for a free home energy visit.

    - Borrow the Home Energy Audit kit from the Mt Gambier Library.

    - Confused about how to use the Powermate Meter - we can show you how, we have one that you can set for 24 hours to give a more accurate reading of the electricity use of your fridge and other appliances over a quarter.

    - Use infrared photography to see where your heat is being lost in your home.   One of our members offers this service at a cost.

Junk Mail

  1. How can I read my catalogues/junk mail online?

    Keep Australia Beautiful has partnered with Eco Voice to encourage all Australians to read their catalogues online to reduce waste and litter.

    Figures on how catalogues impact on the environment are scary:

    There are around 8 billion catalogues delivered around Australia each year.

    Junk mail makes up 6% of all paper used in Australia, equating to 240,000 tonnes of paper per year.

    One tonne of catalogue pages uses 90,000 litres of water to produce.

    We could fill 8,640 Olympic swimming pools with the water used to produce a year's worth of catalogues.

    (Source: Robert Wong, CEO of Catalogue Central)

    It is time to reduce this senseless waste and say “No to Junk Mail” – read your favourite catalogues online at Eco Voice -


    The Challenge

    Keep Australia Beautiful needs help to get “No Junk Mail – I read my Catalogues Online at Eco Voice” stickers on as many letterboxes across Australia as possible.

    Keep Australia Beautiful has partnered with Eco Voice who will soon have bundles of stickers available for schools & community groups to use as fundraisers to spread the word and make revenue (perhaps) for their other sustainability programs.

    So get your school or community group involved today. By getting involved, you will be helping the environment by:

    Reducing the junk mail litter that ends up on our streets

    Saving water and paper used in printing the catalogues

    Raising funds for your school or group eco project and

    Raising funds for Keep Australia Beautiful

    And with Keep Australia Beautiful Week kicking off on Monday 23 August, now is the perfect time to get started.

Solar panels

  1. What is the rebate for solar panels?

    This seems to be changing all the time. from 1st July 2011 the Commonwealth Government rebate is now $3000 - how long it will stay at $3000 is unknown.  Currently State Governments are paying a Feed-in Tariff which pays the customer so many cents per kilowatt of power generated by their solar panels.  In SA this is a net tariff - the panels generate power - the home uses it - what is not used is sold to the grid and your power company pays you this amount - usually it comes off the bill.  The less power you use - the more you earn. This can make payback times under 10 years for a 3kw system.  To find out the payback time for your system go to the Portland Sustainability website at

  1. What does my donation go towards?

    CINEMA CAS has been supported this year by a grant from South East Natural Resources Management Board which ended June 30th 2012 and also the use of the Dress Circle as our Venue is supported by City of Mount Gambier.  CAS need to pay for cleaning and security at the Dress Circle Venue. Other costs include supper and posters.  Our grant has now finished and we will depend on donations to cover the costs for further film screenings this year.   The grant combined with the door donations covered the costs of CINEMA CAS.  

    We would like to thank the media for their support ABC local Radio, 5SE, 5GTR FM, Lime FM, Win TV and The Border Watch and Nelson Notes.  

  2. How successful have these screenings been.

    Community Action for Sustainabiltiy decided to hold CINEMA CAS this year as an entertaining way of getting more people involved and aware of us and to start valueing our environment and our need to live sustainably and build community resilience.  The screenings of the first 5 documentaries have been successful.  Our first documentary - The Economics of Happiness in March had 97 present with 45 staying for discussion, with many great ideas coming out of this discussion. Many of these were new faces. 

    Second documentary Flow in April  - 37 attended also many new faces. In April, we also held a childrens film screening with Art and Snacks in Combination with Riddoch Art Gallery to screen the Lorax and Gavin the Leafy Sea Dragon - 60 children with parents attended and this was very successful, thankyou to Raz for all those pikelets!. 

    In May, CINEMA CAS screened Common Ground with an Aboriginal Australian message and we thank Aunty Hilda who provided us with a welcome to Country. We also showed Urban Roots at this event.  57 people attended this event. 

    In June CINEMA CAS screened Design for Life about the Food Forest in Gawler and 97 people attended.  Another successful event.
