Most people want to save energy and reduce emissions. But it’s hard to know where to start – and where to get the biggest bang for your buck.
Here’s a graphic that should help: the Energy Efficiency Pyramid, with three simple stages!

So pleased to be returning to #UNB again today to present to all final year engineers. Topic: the challenges of climate change, and the opportunities our energy transition offers. It's one of my favourite audiences, because of the critical roles engineers will play in decarbonizing our world.

So - what was the carbon footprint of last summer's epic 16,000 km cross-Canada EV road trip? And how does it compare to doing the trip with a gas vehicle like a Civic sedan or an F-150 pickup? Finally got to doing the math; some interesting results here: changeyourcorner.com/the-carbon-f...

If you want to learn what's at the absolute root of our climate crisis and can handle blunt honesty: it's the notion of exponential growth in a finite world - the very principle that underpins our economic thinking.
