Keynote Speakers

PHIUS is honored, proud and delighted to announce that Jeremy Rifkin will deliver the opening keynote address at the PHIUS 14th Annual North American Passive House Conference!

Jeremy Rifkin

Gunnar Knechtel Photography

Jeremy Rifkin

The list of Rifkin’s accomplishments and ongoing thought leadership simply won’t fit in this space. Let’s just say that not many people can describe themselves as author, economic and social theorist, advisor to the European Union and heads of state, and President of the Foundation on Economic Trends.

Rifkin’s New York Times bestselling book, The Third Industrial Revolution, provided the blueprint for the economic transition to a post-carbon ecological society across the European Union. In The Zero Marginal Cost Society, he describes how the emerging Internet of Things is driving down the cost of goods and services.

As for his current book, the title speaks for itself: The Green New Deal: Why the Fossil Fuel Civilization Will Collapse by 2028, and the Bold Economic Plan to Save Life on Earth.

Rifkin is uniquely qualified to help our passive building community understand how we can drive a cost-effective zero carbon world.
