Alex Honnold is one of the world’s best rock climbers, famous for
his free solo ascents of big walls, including his 2017 first free
solo of El Capitan in Yosemite.
Alex began studies in engineering at the University of
California-Berkeley but dropped out to pursue his passion for
climbing, living out of his van. He first attracted attention
within the climbing community in 2008 when he became the first
climber to free solo Half Dome in Yosemite. In 2012 he
established the speed record for the Yosemite Triple Crown,
climbing three big walls in under 19 hours. With Hans Florine,
Alex climbed the popular Nose of El Capitan, a nearly 3,000-foot
granite wall, in a record time of two hours 23 minutes and 51
seconds – a feat National Geographic described as perhaps " the
greatest feat of pure rock climbing in the history of the sport."
Alex has been profiled by 60 minutes and the New York Times,
appeared on the cover of National Geographic and starred in
numerous adventure films. In 2015, together with professional
climbing writer David Roberts, he authored Alone on the Wall, the
story of seven of his greatest climbing feats up to that year.
In 2012 Alex founded the Honnold Foundation to provide solar
power to some of the disadvantaged communities he was coming
across in his climbing career. In 2021 the Foundation supported
44 communities across 17 countries with its brand of
community-centered innovation catalysed by solar energy.

What if the energy transition isn't a race, but a steady march
toward the end of fossil fuel usage? Do we need to move more like
the tortoise, and less like the hare? And in a world of competing
narratives, who gets to define "pragmatism"?
In this season finale of Cleaning Up, hosts Michael Liebreich and
Bryony Worthington unpack these questions as they review Season
15's most compelling conversations about energy transformation,
and celebrate five years of Cleaning Up.
They dissect the current political landscape, particularly the
challenges facing clean energy in the United States, and Bryony
grills Michael on his recent Bloomberg essay on the "Pragmatic
Climate Reset."
This is the final episode of Season 15 of Cleaning Up, join us in
September for the start of Season 16.

In February, veteran fossil industry advisor Dan Yergin and two
co-authors published a piece called The Troubled Transition. In
it they dismiss the idea that there is or can ever be an energy
transition, anchored on the fact that fossil fuels contributed
85% to so-called primary energy in 1990 and still contribute 80%
today.
Needless to say, their argument has been widely amplified by the
oil and gas industry. They conclude with a demand for a new
approach – which they call a “pragmatic path”.
Pragmatism is needed, but not the pragmatism of defeat. Not the
‘pragmatism’ of believing fossil fuels hold the key to further
human progress. Not the ‘pragmatism’ of addressing climate change
only if it suits the interests of fossil-fuel companies. What is
needed is the pragmatism of robust but affordable climate
action.
This week on Cleaning Up, Michael Liebreich debunks narratives
that trumpet the alleged failure of climate action, and explains
why a pragmatic climate reset is needed.

Is the US about to enter a new era of energy inflation? Can
technological progress outpace political regression? Are we
witnessing the permanent end of America's climate ambitions?
This week on Cleaning Up, Michael Liebreich sits down with Ethan
Zindler, former climate counselor to Treasury Secretary Janet
Yellen, now head of countries and policy at BloombergNEF, to
dissect the dramatic shifts in US energy policy.
Fresh from the passage of the "One Big Beautiful Bill," Zindler
reveals how recent legislation in the US could set back clean
energy development by years, potentially undermining investments
in wind, solar and electric vehicles.
There are a couple of brighter spots too, with costs in some
technologies falling so rapidly that they might escape the drag
of the current administration, and other technologies — like
advanced geothermal and nuclear — seeing an uptick in
support.
Zindler brings the latest analysis from BloombergNEF to Cleaning
Up to help unpack the One Big Beautiful Bill and what it means
for the future of US energy policy.
