It’s official, 2017 was a record-breaking year for rooftop solar installations in Australia in spite of our government’s desire to slow renewable energy development and prop up fossil fuel industries as long as possible. It’s no surprise really, given the fact that electricity prices across the […]

Feb 9, 2018: Cooking With Compost

In last week’s Newsletter I wrote about some developments in Waste-to-Energy Systems around the world. One of the systems I mentioned is called Home Biogas and, as the name suggests, it is a domestic system that takes organic waste like food scraps and even human waste, and turns it into odourless methane gas which is […]

The Last Word on Tile Roofs

This week I was sent some interesting articles about both industrial and domestic-scale waste-to-energy systems. These outline some very promising developments in the technology needed to convert wastes into usable forms of energy. I’ll get to those in a minute. Firstly I’d like to round out the discussion we’ve […]

Jan 16, 2018: Should I Replace My Tile Roof

In our last two Newsletters I’ve talked about why brick veneer houses with tile roofs are such a bad choice for Australia’s climate. To reinforce that point, here’s quote from Harry Seidler (‘famous’ Australian architect) which was written in 1954 and sent to me yesterday by one of our readers.

‘…topping it all there is […]

Dec 22, 2017: Upside-down Season

Happy Summer Solstice everyone… except, of course, our readers in the Northern Hemisphere who are celebrating their Winter Solstice today.

Winter Solstice seems like more of a reason to celebrate. It is the shortest day and the darkest time of the year. After the Winter Solstice the days start to get longer and there’s […]

Dec 8, 2017: Bitcoin Climate Disruption

Is Bitcoin adding to Global Warming? (Image Source: news.bitcoin.com)

In last week’s Newsletter I mentioned a Guardian article which claims that processing of Bitcoin transactions now requires more energy than the entire country of Ireland. My friend Kevin responded with a link to this article from Grist which makes the following predictions (emphasis mine)…


Dec 1, 2017: The Coming Disruption

When you have an hour to spare I strongly encourage you to watch the following video presented by Stanford University Futurist, Tony Seba, about the impending disruption of the transport and energy sectors. Here are just some of the information it presents:

Electric Vehicles (EV’s) have 100X fewer parts than Infernal Combustion Engine Vehicles (ICEV’s) […]

Nov 24, 2017: Suncrowd Review – 0 Stars

Please allow me to begin this week’s Newsletter with an apology for my part in helping to organise the Suncrowd events that were held in our region a year ago and for helping to persuade people that this Community Solar Bulk Buy program was a good idea. It certainly seemed like one at the time […]
