It's true emissions from public transport aren't as low relative to cars as is popularly imagined, but the savings are still significant. And there are other good reasons to invest in worthwhile transit services.

In the US, homes with a swimming pool use a whopping 49% more electricity and 19% more gas than homes without one. Yet it’s not the pool itself that’s the main problem.

Ken Parish at Club Troppo draws attention to a new report that confounds the conventional wisdom on peak oil and, if correct, has important implications for cities. It’s published by Harvard University’s Belfer Centre for Science and International Affairs. It concludes that oil supply capacity is growing worldwide at such an unprecedented level, it might […]

We’d almost be there if we could generate most electricity from renewable resources. Or so you might think. Yet the Australian Conservation Foundation (ACF) disagrees. […]

I’ve written before (e.g. here and here) about understanding the importance of selection bias before attributing significant behavioural influences to the physical environment. More often than not, it’s the characteristics of the people that explain more about their behaviour than the type of neighbourhood or housing they live in. The Australian Conservation Foundation’s (ACF) well […]

Earlier this week I watched the Four Corners story, Against the Wind, on the alleged health impacts of wind turbines and came away wondering just what the point of the program was. Based on what I saw, my clear impression is there’s no issue here – there’s simply no hard evidence of the supposed health […]
