Axiverse Cosmology and the Energy Scale of Inflation

Ultra-light axions (m_a
I will also present preliminary results of constraints to this model using up-to-date cosmological observations, which verify the above picture. The parameter space is interesting to explore due to a strongly mass dependent covariance matrix, motivating comparisons between Metropolis-Hastings and nested sampling. Finally I discuss fine-tuning and naturalness in these models.

Energy and the Environment - What Physicists Can Do

The global warming
crisis is part of a bigger transformation in which humanity realizes that the
Earth is a finite system and that our population, energy usage, and the like
cannot continue to grow exponentially. While politics and economics pose the
biggest challenges, physicists are in a good position to help make this
transition a bit easier. After a quick review of the problems, we discuss a few
ways physicists can help. 

Energy: The Way We Share on TVO's The Agenda with Steve Paikin

As the world’s population inches toward the 8 billion mark, energy
experts look at how supply and demand of energy will affect global
economics and politics in a moderated discussion on TVO’s The Agenda with Steve Paikin. Speakers include: Jason Blackstock, Jian hua Ding, Velma McColl, Vagish Sharma, and Jose Maria Valenzuela

Technology, Energy and Nature - Human Values and Open Choices

As humans, we have developed technologies to control energy
transformations from agriculture to nuclear weapons. Increasing
technological ability has co-evolved with increasing intensity of energy
use and growing complexity of our civilization. These forces have
shaped our environmental footprint and our very conception of nature.
It's tempting to believe that physical limits constrain our energy
and environmental choices as never before; but Dr. Keith argues
precisely the opposite: our growing technological leverage makes access

Energy Transitions

Energy transitions: a future without fossil energies is desirable,
and it is eventually inevitable, but the road from today's
overwhelmingly fossil-fueled civilization to a new global energy system
based on efficient conversions of renewable flows will be neither fast
nor cheap.
Distinguished Professor and author Vaclav Smil explores technological
transitions of past, present and future that are critical for
understanding how to shift to a low carbon future.

Ensuring Electricity: What Happens if the Lights Go Out?

Today we rely on just-in-time delivery of electricity that is sometimes
vulnerable to natural disasters and failure at peak demand. This plenary
session examines the reliability, resiliency and security of emerging
technologies in an increasingly electrified energy system. Speakers
include: Bill Rosehart, Maria Skyllas-Kazacos, Ted Sargent, and Walt

Plugging in the Planet: Building Capacity for the Future

This plenary session examines today’s emerging energy technologies as
well as the challenges associated with meeting global demand as we move
toward an increasingly electrified energy system. Speakers include: Jay
Apt, Yacine Kadi, Craig Dunn, and Greg Naterer

Energy: The Way We Move on TVO's The Agenda with Steve Paikin

Trains, planes and automobiles — what are we doing to find new resources
and modes of transportation? And will it lead us to rethink how we
live? Energy experts participate in a moderated discussion presented
live on TVO’s The Agenda with Steve Paikin. Speakers include: David Keith, Greg Naterer, Maria Skyllas-Kazacos, Aaron Leopold, and Jeff Casello

Energy: The Problem To Solve on TVO's The Agenda with Steve Paikin

How hopeful can we be about new technologies paving a path away from our
current reliance on oil-based energy? Energy experts investigate the
alternatives in a moderated discussion presented live on TVO’s The Agenda with Steve Paikin. Speakers include: Barry Brook, Walt Patterson, Tom Rand, Zoë Caron, and Jatin Nathwani

Benchmarking for our Energy Future

If we are to advance technological systems for a low carbon and
electrified future, how do we measure progress? Through animated videos
and a panel discussion with energy experts, this kick-off session
introduces some of the technological challenges and implementation
hurdles to be overcome if we are to meet our future electricity needs.
Speakers include:Barry Brook, Walt Patterson, Jatin Nathwani, and Robin Batterham
