|---|---|---|---|---|---|---|
| The Evolution of Nexus Research and 'Thirst for Power' | 4 | 3 | 1 | 1 | Shayle opens by asking Dr. Webber about the origins and reception of his 2016 book Thirst for Power. Dr. Webber explains the evolution of academic and agency funding for nexus research over the intervening six years in a collegial manner. | |
| Quantifying Energy Requirements in Water Supply Chains | 4 | 6 | 1 | 1 | Webber provides quantitative breakdowns of the energy embedded in water infrastructure, highlighting that 13% of US energy use is for water and steam. Shayle prompts with clarifying questions as Webber contextualizes residential water heating against the total energy use of Sweden and Switzerland. | |
| The Massive Water Footprint of Energy Generation | 5 | 7 | 2 | 2 | Shayle asks Webber to drill down on water withdrawals versus consumption for energy generation. Webber delivers an extensive tutorial explaining that cooling thermal power plants accounts for roughly 40% of all US water withdrawals, vastly outpacing municipal drinking water. | |
| Economic Interdependence and Desalination Economics | 6 | 5 | 2 | 2 | Shayle and Webber explore cost stacks and the asymmetric economics between water and energy. Webber introduces Jevons paradox to show why cheaper electricity might not automatically lower overall water expenditure if energy-intensive desalination expands. | |
| Long-Term Visions: Nuclear Fusion, Desalination, and Ecological Restoration | 6 | 4 | 2 | 2 | Shayle introduces nuclear fusion economics and questions whether massive fusion-powered desalination is realistic. Webber qualifies that high energy costs dictate water prioritization for basic survival and ecological restoration rather than luxury consumption. | |
| Sponsor Message: Bloom Energy, Engie, and EnergyHub | 5 | 5 | 1 | 1 | Following midroll sponsor announcements, Shayle frames the worsening climate impacts on thermal power and water supplies. Webber elaborates on extreme weather disruptions, citing the Texas freeze where grid failure prompted boil water notices for fourteen million people. | |
| Decarbonization Trade-Offs and Water-Lean Innovations | 6 | 5 | 2 | 2 | Shayle pushes on whether clean energy transition solutions like hydrogen electrolysis or carbon capture swap one resource crisis for another. Webber agrees, contrasting water-lean renewables like wind and solar against water-heavy carbon capture and legacy nuclear cooling. | |
| Antiquated Water Rights versus Modern Energy Markets | 7 | 4 | 1 | 1 | Shayle draws on his venture experience to highlight the extreme opacity and regulation of water rights compared to energy markets. Webber explains how century-old Western water compacts and historical groundwater legal doctrines impede modern market formation. | |
| 2036 Projections and Averting Resource Wars | 5 | 4 | 1 | 1 | Shayle and Webber project forward to 2036, discussing the danger of future water wars replacing fossil fuel conflicts. Webber emphasizes that simultaneous energy and water efficiency remains the most overlooked path to resource abundance. |
Statements from this episode (21)
Kann: 2022 China drought disrupted global EV and solar supply chains
“China is currently experiencing the worst drought on record. The Yangtze River is at its lowest level for this time of year since recorded history. And in the Sichuan province, which is home to a big hydropower resource, threats of power cuts are impacting man…”
Webber: About 13% of US energy consumption goes to water and steam
“If you look at the United States as an example, we use about a hundred quads of energy, a hundred quadrillion BTU of energy. BTU is a British thermal unit of energy. About 13% of that energy is for water and steam.”
Webber: US water heating uses more energy than Switzerland and Sweden combined
“That four percent of national energy consumption in water heating is bigger than what Switzerland and Sweden use for all purposes combined in a year.”
Webber: About a third of US energy boils water in power plants
“It's like a third of our energy consumption in the United States just goes to boil water to make steam in power plants.”
Webber: Coal plants now store only 15 to 30 days of coal
“And these coal plants in the old days maybe stored 60 days worth of coal on site. These days they store like 15 to 30 days.”
Webber: 40% of US water withdrawals cool power plants
“And about 40% of all the water withdrawals in the United States every day are just to cool power plants.”
Webber: Agriculture is the top net water consumer, ahead of cities and power
“If you look at consumption, how much water is consumed, agriculture is the biggest consumer, and then cities, then the power sector.”
Webber: Energy costs make up about half of municipal water bills
“Rule of thumb is about half, depends on where you are. So your water bill depends on where you are. My water bill in Austin, Texas is about a hundred bucks a month. It's a lot cheaper in other parts of the United States because water is scarce in Texas, so it'…”
Webber: Water inputs cost only $0.50 to $1 per barrel of oil
“The water bill for energy is not substantial. Usually the water is cheap. So if you're producing oil and gas, the amount of extra money you pay for water, it's something you notice. It might be 50 cents a barrel or a dollar a barrel, something like that, but t…”
Webber: Cheaper energy may drive energy-intensive desalination via Jevons paradox
“The correction to that might be, if you lower the cost of energy, you might end up pursuing more energy-intensive forms of water-like desalination, so it might end up settling out at about the same price. And in fact, that's what we see in many places, is that…”
Kann: Nuclear fusion will not inherently provide the cheapest electricity
“It's not inherently true that it's going to deliver the cheapest electricity. That is available on the market, even if it is fusion. It, that doesn't mean that it's cheap because you still have, you could have very expensive capital costs to build a fusion pla…”
Webber: Water-scarce regions already use desalination despite high electricity costs
“We don't have to wait for the far future for desalination. It's already happening today in Israel and In parts of California, and inland Texas, and Israel, and Australia. So places that are water scarce already do some desalination. Even if the electricity is …”
Webber: French nuclear plants curtailed output due to drought in 2022
“You cannot get the water you need to cool your nuclear power plants in France so they are dialing back or turning off.”
Webber: Texas 2021 storm left 14 million under boil-water notices
“And we had that in Texas where we first had a power outage, ten million people without power, but then we had fourteen million people under a boil water notification, Because the water wasn't safe to drink because the water and wastewater treatment plants didn…”
Webber: Energy emissions and water disruptions form an accelerating feedback loop
“Part of that is one of the deep ironies of the energy-water nexus is that the energy system helps create climate change through the radiative forcing of the emissions from the fuels we use, and the way climate change manifests itself is through changes to the …”
Webber: Nuclear, carbon capture, and bioenergy are highly water-intensive
“Traditional nuclear, 19 seventies nuclear with big water cooling, very water intensive. Carbon capture systems are very water intensive. Bioenergy crops are very water intensive.”
Webber: Fuel choice impacts water use more than improving heat exchangers
“But I think the primary choice is ultimately on the energy side. Fuel choice has a bigger impact than improving the heat exchangers.”
Webber: US water usage and withdrawal data is released only every 5-10 years
“The water side is much less sophisticated, and the information about water quantities that are used in the United States are released every five or 10 years. Same with water withdrawals.”
Webber: US water desperation will soon force creation of trading markets
“We're not quite at that point in the United States or elsewhere, so we haven't had the desperation, but it feels like we're knocking on the door of it, and we'll get there soon.”
Webber: Decarbonization will reduce water intensity by 2036 despite severe strains
“And so I think there'll be some celebration of how the process of decarbonization reduced our water intensity overall, but we're still going to have some pretty severe strains we have to deal with.”
Webber: Oil and gas conflicts risk being replaced by water wars
“But I worry that we're going to replace oil resource wars, or what we're seeing today, natural gas resource wars, with water resource wars. There have been water wars in the past. I'm worried that we'll have more water wars. That, that's something I really am …”
