As you may have heard, solar energy is having a moment. Thanks to several technological breakthroughs, it’s now the cheapest form of energy generation in most places on Earth. This past summer, for the first time ever, it became the EU’s main source of electricity, and many other parts of the world — Pakistan, Nigeria and most famously, China — are likewise in the midst of a solar boom of astonishing speed and scale. In this episode, experts weigh in on the social, political and economic implications of this revolutionary energy shift — and the complicated way that Canada fits into it all.

Featured in this episode:

Sara Hastings-Simon is an associate professor in the department of Earth, Energy and Environment and an assistant professor in the School of Public Policy. Her work focuses on understanding how low-carbon energy transitions happen within different sectors of the economy, constrained by existing infrastructure and business models, and how policy response can improve outcomes. She also hosts, alongside David Keith and Ed Whittingham, the live webinar and podcast Energy vs Climate.

Mike Andrade is the chairman and CEO of Morgan Solar, a Toronto company whose products improve the performance of solar projects and the energy efficiency of buildings. A former executive at IBM and a founding member of Celestica, he’s also an investor and advisor to several other companies, a member of the Council of Canadian Innovators and a board member of the Next Generation Manufacturing Supercluster.

Chris Caners is general manager at SolarShare, a renewable energy co-op in Ontario. He’s also a consultant who advises organizations on climate, energy efficiency and sustainability.

Thomas Timmins leads the Canadian energy sector practice at Gowling WLG in Toronto. He specializes in helping clients navigate opportunities in the global energy transition.

Deb Chachra is a professor of engineering at Olin College and the author of How Infrastructure Works: Inside the Systems That Shape our World.

By uncovering critical sex-based differences related to brain and metabolic health, researchers Gillian Einstein and Minna Woo are making the case that tailored interventions are key to improving health outcomes for women — and everyone else. Through their work exploring how conditions from Alzheimer’s to kidney disease can have varied effects depending on a patient’s sex, they underscore what the medical community as a whole can learn from experts in women’s health: Things aren’t as simple as we want to believe. In this bonus episode, recorded live on May 8, 2025, at the MaRS Impact Health Conference, Einstein and Woo discuss the complexity of biology, the challenges of funding and why they’re optimistic that things are changing.

Gillian Einstein is the Wilfred and Joyce Posluns Chair in Women’s Brain Health and Aging and a psychology professor of psychology at the University of Toronto. She’s also an adjunct scientist at Baycrest and Women’s College Hospitals, and an honorary doctor of medicine at Linköping University, Sweden. Her lab’s current focus is on estradiol loss as well as how stigma and immigration affect memory and cognition in diverse populations of women.

Minna Woo is currently the director of the Banting and Best Diabetes Centre at the University of Toronto and recently completed a 10-year term as division director of endocrinology and metabolism at the Toronto General Hospital, University Health Network (UHN). She now holds the Ajmera Chair in Molecular Diabetes Research at the Toronto General Hospital Research Institute and is a clinician scientist and a staff endocrinologist providing diabetes and endocrine care at UHN. Her laboratory focuses on molecular mechanisms that determine the pathogenesis of insulin resistance and related diseases. She has published more than 100 research articles and her research is internationally recognized as a member elect of the American Society of Clinical Investigation.

Katherine Ward is an award-winning journalist currently working with Global News in Toronto. She joined the team in 2018 and has covered a wide range of stories taking her all over Ontario. This year, Ward was also part of an investigative team that exposed the prevalence of lead contamination in drinking water. “Tainted Water” went on to win a national award with Canada’s Radio Television Digital News Association.
