Unless you’ve been living under a rock for the past year, you’ve heard of Tesla and it’s Powerwall home battery. Whilst the economics of home batteries hasn’t reached the tipping point for mass uptake of the technology, it is certainly going to in the not-too-distant future. This is a familiar story in the energy industry,… Continue reading The Oldest (and Cheapest) Energy Storage
Food. We all eat it and most of us like it. Where it’s grown and how, though, can have both huge environmental and health impacts. A lot of the food we eat comes from large intensive farms. Intensive farming requires nutrient rich soil but with each crop, nutrients are extracted from the soil. To keep the… Continue reading Grub
I recently travelled to South Africa which, for me, highlighted the contrast between the developed and developing worlds in a beautifully humbling way. And humbling it should be, for those of us concerned about the consequences of climate change, because it is those in the developing world who are at most risk from rising sea levels… Continue reading Energised

After about 18 months of reasonable use, I upgraded the software as soon as Apple told me to. It was one of those things that pops up on your phone and you… Continue reading Environomics
There’s been a lot of focus of late on two areas of the climate debate: reducing household energy consumption and increasing generation from renewable sources. This is only half the battle, though, because a vast proportion of the energy we use is actually in the manufacture and transport of our stuff. Recent PhD work at… Continue reading Energy Cannot be Created or Destroyed
If you’re anything like me you get this warm, fuzzy feeling when you take out your recyclables. We’ve come a long way from the mid ‘90s both here in Australia and world-wide which is when recycling became cheaper than landfill disposal (source). Here in Australia we do a pretty good job, with around 60% of… Continue reading Recycling: Environmental Saviour or Guilt Assuager?
Let’s talk about Waste. We produce a lot of it here in Australia yet it doesn’t get as much press as other forms of waste such as emissions from energy or transport. On average each Australian produces more than two tonnes of waste every year. Around half of that is recycled (depending on which state… Continue reading Composting
