Music – Society – Planet

A guide to this website

Music

  • Gig guide – My upcoming adventures on stage with my friends in folk music and trad jazz are detailed on my Gig Guide.
  • WOMADelaide – This is my favourite weekend of the year, and you’ll find some WOMADelaide stories here.

Society

  • Inspirational activists – I’ve been lucky enough to meet and interview some extraordinary people, activists who work tirelessly to be on the right side of history: people who know the inequity of the status quo simply isn’t good enough and must be challenged. You’ll find some activist stories here.

Planet

  • Saving the planet – It’s a slightly silly phrase – “saving the planet” – because the planet is quite capable of looking after itself. In fact if humans disappeared off the face of the earth, the planet would doubtless do better without us. But what we urgently need to do is to preserve our fragile life-support systems for the sake of future generations. We have a lot of work to do in both climate activism and practical emissions reduction projects. There are some examples of climate action here.
  • Urban Ecology Australia – For a couple decades I’ve been a member of Urban Ecology Australia, an organisation that invented a cohesive theory of ecological cities, defined Ecopolis Development Principles, and then set about building a living example of an inner-urban eco-village: Christie Walk. You’ll find posts about my most recent sustainable living adventures here.

Episode 9 – Battery storage – adding a second Tesla PowerWall

2021 – Battery options modelling

In September 2020 we installed our first battery at Sturt Apartments, Christie Walk. You can read the story of our modelling, battery choices and lessons learned in Episode 7 – Battery storage – Tesla PowerWall 2

Everything had gone to plan with the installation of the battery; performance was as expected. The savings generated by our PV upgrade and the battery were flowing into our Green Fund, enabling us to begin planning for the installation of our second battery.

Our modelling indicated that our 21kW PVs were generating enough power to usefully support up to about 55kWh of battery storage, corresponding to 4 x Tesla PowerWall 2 batteries. In cost-benefit terms, a sweet-spot would be with 2 batteries. In the depths of winter in July – on many days – we’d still generate enough spare power to fully charge the batteries for use after sundown.

Episode 7 – Battery storage – Tesla Powerwall 2

2020 – Battery options modelling

In the middle of all that work on evacuated tubes, we learned that change was imminent in the SA Government Home Battery Scheme. To qualify for the maximum $6k subsidy, applications had to be lodged by 15th April.

Our modelling indicated that our 21kW PVs were generating enough power to usefully support up to about 55kWh of battery storage, corresponding to 4 x Tesla PowerWall 2 batteries. In cost-benefit terms, a sweet-spot would be with 2 batteries. In the depths of winter in July we’d still generate enough net power to fully charge the batteries for use overnight.

Episode 6 – More evacuated tube solar hot water boosters

Adventures with an environment-conscious inner-urban community

2020

This was the crisis year for so many people – bushfires, COVID, job losses – and it also happened to be the year of our most adventurous emissions-reduction planning, carrying out 2 major projects a few months apart.

Stage 2 solar hot water boosters

The evacuated tube solar hot water boosters we had installed in 2018 were performing well, so it was time to build the second stage. We’d completed the design work in 2019 and had commenced the Development Application (DA) process with the City of Adelaide in September 2019. DA is required by Council if solar collectors are not mounted flat on the roof. After 9 weeks of back and forth, providing additional drawings and details, we finally received Planning Consent in mid-November.

Episode 5 – Finalist – Carbon Neutral Adelaide Awards

Adventures with an environment-conscious inner-urban community

2016 to 2019 – Carbon Neutral Adelaide

Since 2016 we’d had regular contact with the Carbon Neutral Adelaide team, culminating in our carbon emission inventory for the 2017 year. I’d also attended the Carbon Neutral Adelaide Awards nights in 2017 and 2018.

I’d found the Awards nights to be highly motivating. To be in the room with such a mix of corporates, NGOs, SA Government and Adelaide City Council people, all focussed on working more efficiently and will less emissions was memorable and inspirational.

Episode 1 – In hot water again

Adventures with an environment-conscious inner-urban community

April 2016

Our apartment building (Sturt Apartments at Christie Walk) was nearly ten years old. It was time to start thinking about sustainability upgrades to reduce our carbon footprint.

Lighting was an easy place to start.

We worked with Adelaide lighting maintenance specialists Globebusters, who replaced unreliable CFL lights in our atrium stairwell and entranceway with long-life LED oyster lights and floodlights. In the courtyard, twin LED sensor floodlights replaced the old energy-hungry incandescent lights.

May 2016

Hot water; one of life’s great privileges. But our little luxury comes at a cost for us, and a carbon-cost for our warming planet. It’s a particular issue in our 4-level block of 13 apartments.

Aiming beyond NetZero at Christie Walk

Adventures with an environment-conscious inner-urban community

I’m fortunate to live at Christie Walk in Adelaide. It’s a community of 27 homes and gardens on 2,000m2. It was initiated by Urban Ecology Australia in 1999 as a demonstration project, to promote ecologically-sustainable and community-enhancing urban design and development.

The buildings range from stand-alone straw-bale homes to a 4-level apartment block, all designed for comfortable high-density but low-energy living.

Eco-city dreaming comes true

The facilitator asked us to do some dream-work.  That’s normally not so hard, but there we were, standing in an awkward-shaped T-allotment strewn with bits of broken glass and featuring some derelict out-buildings.  The site had previously been a city recycling depot and in a way one of our goals was to continue that recycling heritage.  We were asked to dream of what the features would be for our ideal sustainable-living community on the site.
