SUSTAIN #5: Can we radically reduce the emissions created growing our food?

Growing the meat we eat produces a lot of Australia’s carbon emissions. The four innovations explored in this episode – Rob Kinley’s amazing seaweed, George Peppou’s vat-grown meats, Sebastien Eckersley-Maslin’s vertical farms, and Nick Hazell’s plant-based ‘meats’ – show us a path toward an agriculture that can be radically more efficient.

SUSTAIN #4: Would electrifying everything eliminate carbon emissions?

Inventor Saul Griffith has a radical proposal: electrify everything, saving energy, money, and cutting emissions almost to zero. It simultaneouisly transforms the costs of climate change into enormous opportunities. Co-host Sally Dominguez explores three amazing new battery technologies.

A must-read companion to SUSTAIN:

Saul Griffith’s forthcoming book ELECTRIFY is, well, an electrifying read that makes the clear, and obvious case that electrifying everything (coupled with renewable generation) is the win-win solution for the planet and our economy. Pre-order it here.

Sally Dominguez loves sodium-ion batteries, and here’s a report about why they may come to rival the dominant Lithium-ion batteries we use today…

Sally and I both love ‘structural batteries’ – they’ll allow us to store electricity pretty much everywhere, in pretty much everything. Read about them here.

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.
