A real privilege to welcome Dr. Kate Hanneman to the University of Calgary this week as our Visiting Professor.
Her talk on sustainability in medical imaging and planetary health was both inspiring and practical.

Even if you wrapped the entire planet in oil and gas wells,
they’d still end up as stranded assets as the world moves on to cleaner (and cheaper) energy.
One of the biggest mistakes fossil fuel execs can make is
equating SHORT-TERM PROFITS with LONG-TERM REALITY!

☀️ Solar cost has dropped 99.8% since the 1970s—90% in the last decade alone.
The driving force behind this? Increased deployment and economies of scale.
So Canada’s solar does more than reduce domestic emissions—it send a signal to global markets, encouraging investment in solar elsewhere.
