SUSTAIN #3: Can we collect and store enough renewable energy to replace coal-fired electricity?

In 2020, renewables became the cheapest source of electricity – and frequent guest Ramez Naam brings us all the stats about this fully underway transition to solar and wind power. But without cheap storage, renewables will never be able to be the entire solution for a world that looks to need a lot more electricity. Australian startup MGA Thermal may have invented the ideal technology to accelerate our transition from coal to solar.

Read this article about how much wind energy the USA added to the grid in 2020 (a record!)

Here’s a Techcrunch article about MGA Thermal getting backed by Australian VCs Main Sequence – and their power station trial in Switzerland.

And finally, here’s a story about the day that solar generation (briefly) eclipsed generation by coal-fired plants in Australia’s winter!

SUSTAIN #2: Will electrified transport help us ‘flatten the curve’ on climate change?

Mercedes goes all in on EVs, with studies now indicating EVs do save 50% of emissions over their lifetime, versus petrol vehicles. Is this enough to keep on course to a low-carbon future? And what about flying cars? Co-host Sally Dominguez and Special Correspondent Drew Smith have some answers.

Mercedes goes all electric by 2030 – read about it here.

Study confirms EV has much lower lifecycle emissions than petrol vehicles – read that here.

Here’s that mindblowing video from Joby Aviation, showing how quiet this eVTOL ‘flying car’ really is!
And a really long flight with their aircraft – proof that electrification of air travel can work!

SUSTAIN #1: Can we ‘flatten the curve’ on climate change?

The recent UN report on climate change gives us about twelve years to really reign in our carbon emissions. That means it’s time to think clearly and methodically about how to get the most benefit for the least pain. We can do this!

At nearly 4000 pages, the IPCC Sixth Report on the Physical Science of Climate Change isn’t a quick read — but the first hundred or so pages contain the condensed facts. Everything you need to know to make decisions today to keep us on SSP1 – the path toward no more than 1.5ºC warming. Grab it here.

GEOPOLICHIPS #4: Will the next war be fought for control of semiconductors?

TSMC – Taiwan Semiconductor Manufacturing Corporation – now fabricates the best computer chips available at any price, transforming Taiwan into a prize that China needs in order to continue its rise as an economic and military superpower.

To service the growing demand for semiconductors, South Korea has committed nearly $200 billion.

TSMC is planning on investing at least $100B over the next four years.

Episode 5.08 – What stands in the way of electric vehicles?

Co-host Sally Dominguez and special correspondent Drew Smith explore the many facets of vehicle electrification with Mark. EVs are finally happening – but does that make them inevitable?

Episode 5.05 – Has Europe gone ‘all-in’ on electric vehicles?

Special correspondent Drew Smith explores a European car market that appears to have reached a tipping point in sales of electric vehicles. Is it real? Is it sustainable? Can the power grid handle all those new EVs?

Drew asks the experts – and gets some surprising answers.

Episode 5.04 – Series 5 Predictions: Has social media turned us all into conspiracy theorists?

The Capitol Insurrection, #wallstreetbets and Facebook’s brief war with Australia demonstrate the power of social media to change how we believe – and behave.

At the end of this decade, could social media drive us all into our own private worlds of fantasy, conspiracy, and fakery?

Episode 5.03 – Series 5 Predictions: Can we make friends with a superpower China?

Prediction: Our long-running low-level spats with China are the new normal, the Chinese superpower rubbing up against the regional power of Australia.

Series 5 continues with some predictions on geopolitics in this decade, when America and China swap positions, and political power tilts eastward.

Episode 5.02 – Series 5 Predictions: Will you own an electric car this decade?

Prediction: At least half of all passenger vehicles sold by 2030 will be electric, revolutionising transportation – and energy.

Series 5 continues with more bold predictions for the next decade — an era of transition and remediation, as we work across multiple fronts and multiple industries – internationally – to cool the climate.

Episode 4.08 – What’s the secret to building a better world?

Do we have surrender our hopes for utopia, or can we learn from others who found the levers to move our world to a better place? Together, are we strong enough to use these tools to change our course?

Deputy Lord Mayor Jess Scully’s new book Glimpses of Utopia: Real Ideas for a Fairer World covers far more ground then we could in our interview – it’s well worth a read!

We were also lucky to hear from Dr. Darren Sharp of the Sustainable Development Institute at Monash University.
