Solve for X: Innovations to Change the World

There’s no denying that technology plays — and will continue to play — a critical role in addressing the climate crisis. But could super-intelligent AI actually solve the problem for us, as several tech billionaires claim? Or is this over-reliance on speculative technology simply a way to distract us from tackling big, real-world problems. Manjula Selvarajah sits down with astrophysicist and author Adam Becker to separate the hype from reality. 
Featured in this episode: 
Adam Becker is an astrophysicist, journalist and the author of More Everything Forever, a book that examines the futuristic ideologies of Silicon Valley’s tech titans. He is a former science journalism fellow at the Santa Fe Institute and was also a science communicator in residence at the Simons Institute for the Theory of Computing at UC Berkeley.
Marcius Extavour is a scientist, creative technologist and communicator who develops solutions for climate change and clean energy. As a partner at Ode, a technology and creative design firm specializing in geospatial AI. He previously built the energy, climate and carbon removal practice at XPRIZE.

Our energy grid is something most of us only think about when it isn’t working. But growing demand for electricity is placing an even greater strain on a system that’s already facing increased pressure from extreme weather events. Can we build a more sustainable and dependable grid? In this episode, which originally aired September 2022, we explore how when it comes to climate change the challenge of greening the grid is as much an issue of complex engineering as it is about policy and equity. 
Featured in this episode:
Josh Wong is the former CEO of Opus One Solutions, which was acquired by General Electric. In 2024, Josh founded a new company called ThinkLabsAI and is developing software that will help utilities to integrate renewable sources of energy and improve grid resilience.
Destenie Nock is an assistant professor at Carnegie Mellon University who specializes in public policy, civil and environmental engineering. She’s an expert on how our changing climate is impacting the grid, and what that means for the future. Focusing on energy equity, Destenie explains what’s important to consider in our transition to clean energy.
Dana Tizya-Tramm is the former chief of the Vuntut Gwitchin First Nation in Old Crow, Yukon. Dana helped establish the Old Crow Solar Project — shifting the northern remote community off diesel to renewables. Through his efforts, Old Crow is making inroads toward energy sovereignty. He is now the director of Nadlii and is working on developing a framework for Indigenous data sovereignty and ethical AI.

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.
