ICYMI: Here's a link to yesterday's episode of Understanding Energy on CBC Radio's #ShiftNB with #VanessaVanderValk - this one on Time of Day (or Time of Use) power rates. They're common elsewhere (including ON, BC, QC) & are likely coming to NB in 2027.

Hear it here: www.cbc.ca/listen/live-...

Wouldn't this be a dream come true: having fossil fuel companies & executives pay for climate damage since they've known all along fossil fuels are the cause; & having a #GlobalWealthTax on the obscenely rich, who couldn't spend all their money if they tried? www.theguardian.com/environment/...

In our system, money makes things happen and lack of money prevents things from happening.

It's RRSP season - so why not choose sustainable investments to ensure your money is funding good things, not bad ones? More info and tips here: changeyourcorner.com/this-rrsp-se...

Segment Two of β€˜Understanding Energy’ aired yesterday on CBC Radio's Shift NB. Topic: how to read your power bill

- why comparing power bills by $ value isn't a good measure

- why KWH/day is what matters

- what to consider if your KWH/day has changed

Wow - Bjorn Lomborg, an economist (not climate scientist) who has long been the darling of the climate denial movement, now surfaces in the Epstein files.

I suppose it underlines that if you're morally corrupt, that corruption isn't limited to one file.

The first segment of β€˜Understanding Energy’ – my new biweekly chat with Vanessa Vander Valk on CBC Radio's Shift NB – aired yesterday. The topic: peak power.

www.cbc.ca/listen/live-...

Suggestions welcome for future topics! Energy is a big deal, and the more we understand about it, the better!

Very pleased to share that I'll be joining Vanessa Vander Valk on #CBCRadio #ShiftNB every second Monday this winter to talk energy.

Our first chat airs January 19, about peak power. (Spoiler: many think it's just a utility problem, but it has huge implications for every NBer.) #cbcnewbrunswick

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!

β€˜Circular Economy’ is the term to describe when industries, manufacturers & consumers do everything possible to eliminate waste & reduce consumption of resources.

As a consumer, why not practice Circular Economy principles this holiday season? Here's how! changeyourcorner.com/savings-from...

We Need a Roadmap for Fossil Fuel Transition at COP 30 Over the last year, thousands of people have added your voice and name to deliver this message to world leaders: It's time to keep your promises.

#DearWorldLeaders, we need real plans to phase out fossil fuels and transition to clean energy. And we need them now. You made a promise, now keep it. clim.cc/dwl #COP30 @environmentca

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...

β€œCanadians will be our own best customer, creating more well-paying careers at home, as we strengthen and diversify our trading partnerships throughout the world." - Mark Carney, in response to our betrayal by the US.

#Elbowsup, Canada, esp in face of the latest tantrum from the betrayer-in-chief.

The suicidal insanity of non-stop growth The planet offers everything we need to survive and thrive, but not if we continue to wastefully exploit it.

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.

A good read, if you're ready for blunt. davidsuzuki.org/story/the-su...

As Coal Fades, Australia Looks to Realize Dream of 100% Renewable Energy The country’s grid operator says shifting from coal to clean power is not only possible but inevitable. The work there could provide a road map for other countries.

β€‹β€œWhen you’re determined to say how best to go about this, as opposed to why it’s hard or why it doesn’t work, the solutions appear.”

Let's leapfrog over new fossil fuel projects and get working on the future we need - renewables with backup.

Oneida Battery Project, Canada’s Biggest, Goes Online Ahead of Schedule, Under Budget Canada’s biggest battery energy storage system went online ahead of schedule and under budget last week, on a patch of industrial land just a few kilometres from the Six Nations of the Grand River in ...

"Ahead of schedule, under budget" - words rarely heard about any major infrastructure project.

It's time to believe in the ability of grid-scale batteries to take the 'intermittent' out of intermittent renewable wind and solar.

BREAKING

President Trump is demanding that the DOJ pay him about $230 million in compensation for the federal investigations into him.

Any settlement will ultimately be approved by senior department officials who defended him or those in his orbit.

Brandolini’s Law (also known as the bullshit asymmetry principle):

The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it.
