June 25, 2016: ‘Renewable Electricity’ is NOT ‘Renewable Energy’

Here in Australia we are just one week away from a federal election and, as usual, the choices are dismal and misinformation abounds. For example, I’m starting to notice that politicians and the media happily use the term ‘Renewable Energy’ when they really mean ‘Renewable Electricity’. For example, the ACT government recently announced that, due […]

June 19, 2016: The Power of TV and The Rise of The Machines

The Power of Television

As I mentioned in our Newsletter a couple of weeks ago, we were recently honoured by a visit from Justin Huntsdale from ABC Illawarra. Justin recorded a video interview which aired on ABC News24 yesterday. As far as I know this is the first time the Greeny Flat has been on […]

June 12, 2016: Magnetite, Drones and Climate Action

Andy here, reporting this week from sunny Canberra where the ice was thick on my sister’s birdbath this morning. Cate (my sister) has a little brick-veneer-and-tile townhouse near Belconnen which she is gradually retrofitting to make it as energy efficient as possible. So far she has insulated the walls and ceiling, installed a solar power […]

June 4, 2016: Stools to Fuels

I’ve heard it said that in ancient China, where most people lived and worked on their own subsistence farm, it was considered highly impolite if you went to visit a friend, ate a meal and left without make a solid ‘deposit’ in the composting toilet. I don’t know if this is true but it makes […]

May 29th, 2016: The Future of Energy?

There is no question that we, as a global society and Australia as a nation, need to act quickly and decisively in the transition to a low-carbon economy. Climate Change is upon us. The evidence is overwhelming. Atmospheric CO2 and methane levels are the highest they’ve been for a million years. Global temperatures are spiralling […]

May 21, 2016: Concrete Alternatives and PCM’s

As promised in last week’s Newsletter, I’m going to write this week about alternatives to concrete for thermal mass in buildings. To briefly recap, an astute reader named Ray, correctly pointed out that concrete is an environmental disaster. Estimates vary but somewhere between 6 and 10% of the world’s carbon emissions are due to concrete. […]

May 15, 2016: First the Good News

Lately there has been an increasing amount of encouraging news relating to the global movement towards a more sustainable future. Two of the world’s largest coal companies, Peabody and Arch, have gone bankrupt in a sign that the age of fossil fuels is coming to an end. Closer to home, this week local landowner’s in […]

May 8, 2016: Underslab Insulation

Before I get into this week’s discussion about insulating under concrete slabs I thought some readers might be interested in a short video of a presentation I gave on the subject of ‘Shelter’ to an Economic Development Summit held late last year. In the video I talk about some of the problems that I see […]

May 1, 2016: Counting Comfort and Costs

In last week’s Newsletter I shared the energy performance results from our second full year in the Greeny Flat. I was very happy to report that we continue to be well and truly energy positive in spite of the fact that we are now putting quite a bit of our excess energy into our Electric […]

Thanks to everyone who came along to help us celebrate […]
