Monthly Discussion Group

The monthly BZE Discussion Group is an opportunity to hear from and question experts leading climate change solutions. Topics vary from renewable energy techincal innovations to social and political action. The event is generally held on the first Monday of every month at 6:30pm at the University of Melbourne.

Dr Hugh Saddler: Why is electricity consumption decreasing?

For more than a century the quantity of electricity consumed in Australia was more than the year before. That all changed in 2010 and electricity consumption has been falling for the past four years. Dr Hugh Saddler, Principal Consultant, Energy Strategies, at pitt&sherry is author of The Australia Institute report Power down: Why is electricity consumption decreasing?

Dr Saddler will talk about, the three largest factors contributing to the dramatic changes in demand for electricity:
1) the impact of energy efficiency programs,
2) structural change in the economy away from electricity intensive industries, and
3) the response of consumers to higher electricity prices.

Dr Saddler takes an in-depth look at each of these factors in his report, explaining what impact they’ve had on Australia’s falling use of electricity. He will join us via video link.

Richard Keech - How Heat Pumps work

Dave and Joe

Heat Pump domestic hot water was a key recommendation from the Zero Carbon Australia (ZCA) Buildings Plan which was released in 2013 to demonstrate how all existing buildings in Australia can reach zero emissions within ten years. Principal researcher Richard Keech will present:

How Heat Pumps work

Heat pump hot water systems use 80% less energy than gas and standard electric-based hot water systems. Richard's presentation will cover:

  • refrigeration cycle
  • thermal modeling, energy calculations and cost savings
  • Coefficient Of Performance (COP)
  • comparison with solar water heaters
  • taking gas out of the equation
  • choosing a heat pump water heater for your home
  • bust common myths

Richard Keech is an engineer working as an energy efficiency consultant.  He was a lead author of the BZE Zero Carbon Australia Buildings Plan and is a regular contributor to ReNew magazine, RenewEconomy, and to the recently released Efficient Hot Water Booklet published by the Alternative Technology Association (ATA).

Earthworker has recently introduced a heat pump retro-fit product designed by Siddons Solarstream,  - here represented by managing director Mr Chris Siddons - that can be added to an existing tank, called the Solar BOLT-ON heat pump. Earthworker founder Dave Kerin has just launched a crowdfunding & facebook campaign to install these BOLT-ON solar hot water heat pumps in low income households. Joe Caygill, Director at Everlast, will also join us to tell us about manufacturing Everlast Solar ready stainless steel Tanks with Earthworker. Follow Earthworker on Twitter with @Earthworkercoop.

Bruce Mountain and Paul Szuster CEM. Rising electricity prices - how rooftop solar helps

Bruce Mountain, Director at Carbon and Energy Markets Australia (CME), has just completed a study comparing power prices from around the world. Australia's electricity prices have doubled over the last five years, making it near the highest in the world.

The traditional model is under threat from consumers being able to produce their own electricity through (rooftop solar) PV systems and possibly increasingly through battery storage and other means to delink from the grid totally. And as they delink, the pool of customers left gets smaller, the total costs of the industry has to be recovered on a smaller customer base, and so prices rise, more consumers leave, and eventually the whole industry can die. This is known as the death spiral and has taken hold in Europe. Join us for a wide-ranging discussion covering solar, the Renewable Energy Target (RET), networks and related issues. CME consultant Paul Szuster will be co-presenting. Paul is an energy analyst with particular interest in the impact of energy policies on utility business models.
