Renewable Energy Target

Charles Rendigs

 

The reduction of extremes in heat or cold without continually increasing power consumption

The answer is provided by Charles Rendigs, the National Business Development manager of "Thermoshield", an Australian company developed and owned, situated at Dandenong. It is a coating for roofs that can be painted or sprayed on, can be coloured by mixing with  red or green paint. White of course is generally used when a high  solar reflective index is desired i.e. in Summer but as it ages its capacity to reflect is naturally diminished.

But Thermoshield can also be used to retain warmth inside in the Winter months i.e. as a form of insulation producing what is called "dead air" space so its properties can work to either reflect or absorb. It can be used in conjunction with  PV as PV usually only covers part of the roof and may heat up around the cells. It can increase the productivity of cells during the day. It can also be complementary to pink batts. air conditioners and other forms of temperature control.

It has been tested by CSIRO and has been used from Queensland to Melbourne. It sounds like a robot acting as instructed!

Tim Forcey: 22 ways to cut your energy bills

How to save money on power bills

This is a headline which should be of interest to everyone!

Beyond Zero's Kay and Michael speaks to Tim Forcey, Energy Advisor, Melbourne Energy Institute, University of Melbourne talks about 22 things you can do to improve your home’s energy performance. And how to reach the ultimate goal of a home heated and powered by 100% renewable electricity. 

My Efficient Electric Home fb group - join us!

Tim has ideas on 22 ways of cutting power bills  and 38% off electricity and gas.  He said there is no economic reason for connection to the gas grid as gas has increased in price 75% over the last  5 years!  To make the production and usage of hot water  go further it is preferable to consider heat pumps and those with smart meters would find it simpler to trace one's usage regularly. It is possible to do this on line for the clever ones (my expression!)

But first on the list is to install LED lights  and thereby  using less power without heating and these are of course now being offered free of  charge. Next it is also a good idea  to ring retailers  to request what discounts are available ot to  threaten to switch if dissatisfied!

But before getting too technical adequate insulation is important  particularly hot water pipes and pressure release valves and a commonsense approach e.g. checking for draughts from old fireplaces and vents and the installatiom of old fashioned drapes and pelmets

Michael raised the question of showerheads which Tim said need not be either giving a satisfying shower or be saving hot water but could be both and if not satisfied could be returned! And that green power is provided by most retailers not only Powershop.

Hannah Aulby

Transition from Coal

Hannah Aulby grew up in Tasmania and she said she had an "environmentally aware youth" and her family were interested in environment matters .Since then she has travelled extensively globally, worked with Nick McKim, been Fundraising manager for BZE, Lock the Gate to mention a few. She is now Clean Energy Campaigner at the Australian Conservation Foundation (ACF).

She mentioned the problem of mine rehabilitation where there is a big need for money to be available for mines at the end of their use. For example Hazelwood (Australia's dirtiest coal fired power station) whose owners are "considering" closure with insufficient funds to so. But there are many who merely desert mines and just leave without legal redress. So it seems then the taxpayer would have to foot the bill. There is also a need too for the communities to plan and have some alternative transition to alternative employment. There is of course too much coal in the system at present.

Hannah concluded by reminding listeners of the Forum - Coral, Coal and Climate Change forum on 16th June at Box Hill Town Hall with Lighter Footprints and  ECAM ( Eastern Climate Action Melb.) as joint hosts. Local candidates and politicians to attend with Rod Quantock as M.C. One can only wonder how/if he can make an endangered Great Barrier Reef light hearted!

Tom Quinn

Tom Quinn on the future of food 

Tom Quinn is Executive Director of the Future Business Council which represents innovative, sustainable and resilient businesses that will define our future economy. He has also worked in the Sustainability area at the  City of Melbourne. Tom joins the Beyond Zero radio team talking about his early upbringing on a farm which he attributes his interest in wildlife and his subsequent choice of occupation. His interests have broadened to include issues such as 'green' buildings, organic food production, health and nutrition, sustainable irrigation and afforestation, to mention a few.

Tom points out that Australia has a "unique opportunity" with the approach of the end of the mining boom in considering "what comes next". He stresses that there are numerous vested interests and lack of bipartisan support which result in "missed opportunities". However, "there are lots of smart people here" in Australia who are able to transform environmentally sustainable ideas into commercially viable projects. One of the important aims for the future is "carbon draw-down", i.e. taking carbon out of the atmosphere. There are many ways to do this, one of which is reforestation.

Tom announced an event on the future of food security in Hobart on 8th June in conjunction with the University of Tasmania Business School, and hopefully engaging with the Tasmanian community on issues of sustainability and productivity.

The Future Business Council has released The Next Boom report which has found compelling evidence that sustainability should not be seen as a cost, but a business opportunity. Tom also talks about the climate policies we would like to see for the upcoming federal election. 

BZE's Michael also mentioned the Coral, Coal and Climate Change forum on 16th June at Box Hill Town Hall which is sponsored by Lighter Footprints, an active local environmental organisation. Comedian Rod Quantock will be present, as well as local and other candidates, including Shadow Environment minister Mark Butler and local member Josh Frydenberg.

Dr Stephen Bygrave on "Empowering Local Communities" 

BZE radio's Laura, Kay and Michael talked to Dr Stephen Bygrave, CEO Beyond Zero Emissions, who described Australia as a "solar paradise" and rated as third globally on the availability of renewable resources but of course rated most extreme when it comes to emissions per capita. Yet as Stephen says the coal industry is "static" and the COALition is "stuck in the old ways". 

This writer is often inclined to feel depressed at the criminal lack of progress and disinterest displayed in the development of renewables so Stephen feels like a breath of fresh air - somewhat equivalent to that of Tasmanian air being sold to China in tins! Travelling widely it seems, Stephen's plans include developing blueprints for  change  across different states and sectors. Addressing the welcome drop in the cost of batteries he says not to forget the importance of agricultural emissions frequently not so recognised, but no less important than renewables (which he described as "more sexy"). The agricultural sector of course includes land use, land clearing, production and wastage of food, water, transport etc. all of which mainly driven by local communities as it seems are most such progressive movements.

On closing Michael mentioned the Newcastle demonstration. which was held the previous weekend where they were watching some of the coal ships depart and estimating each ship to be the equivalent to 100, 000 cars on the road!  So much for Adani v the Great Barrier Reef!

Adrian Whitehead calls for climate action!
