More than NZ$10 billion has been invested in renewables in NZ in the past 15 years, lifting the renewable penetration from 65% of the market to 88% in normal conditions. This investment has been driven purely by economics, in the absence of demand growth and government incentives, unlike in many other advanced economies.
The New Zealand Electricity Authority predicts that their electricity grid will be 100% renewable by 2040.
“New Zealand is transitioning to a highly renewable electricity system. This change will require increased and accelerated investment in new electricity generation to match demand growth and the retirement of thermal power plants.”

From the article:
Fossil fuels’ share of global primary energy fell below 80% for the first time in modern history, a tipping point masked by growing energy demand. Oil’s share of primary energy fell below 30% for the first time in modern history, down a third from its peak. The demand for gasoline and diesel was negative – 2024 may be the year road transport fuel demand peaked– no more growth in this sector anymore. Three milestones that show whilst the energy evolution is not perfect, it is happening nevertheless, and at pace. Even as absolute energy demand still grew, it is telling that many oil majors such as BP, Exxon and Shell, who have recently noted their exit from renewables, are also withdrawing from core oil and gas production investments too. Over 50% of their operating cashflow is now going to shareholders, not explorers or construction crews.
The article goes into each of these points in greater detail, but one of the biggest takeaways here is that oil companies are tactically withdrawing from the energy battlefield--they are redirecting their money to paying off shareholders rather than developing new sources of fossil fuels.
As renewables become cheaper, more popular, and show overall greater potential for future innovation and growth the writing is on the wall that the energy transition is leaving fossil fuels behind.

Circular battery self-sufficiency

I'm coming to DEFCON! On FRIDAY (Aug 9), I'm emceeing the EFF POKER TOURNAMENT (noon at the Horseshoe Poker Room), and appearing on the BRICKED AND ABANDONED panel (5PM, LVCC - L1 - HW1–11–01). On SATURDAY (Aug 10), I'm giving a keynote called "DISENSHITTIFY OR DIE! How hackers can seize the means of computation and build a new, good internet that is hardened against our asshole bosses' insatiable horniness for enshittification" (noon, LVCC - L1 - HW1–11–01).
If we are going to survive the climate emergency, we will have to electrify – that is, transition from burning fossil fuels to collecting, storing, transmitting and using renewable energy generated by e.g. the tides, the wind, and (especially) the Sun.
Electrification is a big project, but it's not an insurmountable one. Planning and executing an electric future is like eating the elephant: we do it one step at a time. This is characteristic of big engineering projects, which explains why so many people find it hard to imagine pulling this off.
As a layperson, you are far more likely to be exposed to a work of popular science than you are a work of popular engineering. Pop science is great, but its role is to familiarize you with theory, not practice. Popular engineering is a minuscule and obscure genre, which is a pity, because it's one of my favorites.
Weathering the climate emergency is going to require a lot of politics, to be sure, but it's also going to require a lot of engineering, which is why I'm grateful for the nascent but vital (and growing) field of popular engineering. Not to mention, the practitioners of popular engineering tend to be a lot of fun, like the hosts of the Well That's Your Problem podcast, a superb long-form leftist podcast about engineering disasters (with slides!):
https://www.youtube.com/@welltheresyourproblempodca1465
If you want to get started on popular engineering and the climate, your first stop should be the "Without the Hot Air" series, which tackles sustainable energy, materials, transportation and food as engineering problems. You'll never think about climate the same way again:
https://pluralistic.net/2021/01/06/methane-diet/#3kg-per-day
Then there's Saul Griffith's 2021 book Electrify, which is basically a roadmap for carrying out the electrification of America and the world:
https://pluralistic.net/2021/12/09/practical-visionary/#popular-engineering
Griffith's book is inspiring and visionary, but to really get a sense of how fantastic an electrified world can be, it's gotta be Deb Chachra's How Infrastructure Works:
https://pluralistic.net/2023/10/17/care-work/#charismatic-megaprojects
Chachra is a material scientist who teaches at Olin College, and her book is a hymn to the historical and philosophical underpinnings of infrastructure, but more than anything, it's a popular engineering book about what is possible. For example, if we want to give every person on Earth the energy budget of a Canadian (like an American, but colder), we would only have to capture 0.4% of the solar energy that reaches the Earth's surface.
Now, this is a gigantic task, but it's a tractable one. Resolving it will require a very careful – and massive – marshaling of materials, particularly copper, but also a large number of conflict minerals and rare earths. It's gonna be hard.
But it's not impossible, let alone inconceivable. Indeed, Chachra's biggest contribution in this book is to make a compelling case for reconceiving our relationship to energy and materials. As a species, we have always treated energy as scarce, trying to wring every erg and therm that we can out of our energy sources. Meanwhile, we've treated materials as abundant, digging them up or chopping them down, using them briefly, then tossing them on a midden or burying them in a pit.
Chachra argues that this is precisely backwards. Our planet gets a fresh supply of energy twice a day, with sunrise (solar) and moonrise (tides). On the other hand, we've only got one Earth's worth of materials, supplemented very sporadically when a meteor survives entry into our atmosphere. Mining asteroids, the Moon and other planets is a losing proposition for the long foreseeable future:
https://pluralistic.net/2024/01/09/astrobezzle/#send-robots-instead
The promise of marshaling a very large amount of materials is that it will deliver effectively limitless, clean energy. This project will take a lot of time and its benefits will primarily accrue to people who come after its builders, which is why it is infrastructure. As Chachra says, infrastructure is inherently altruistic, a gift to our neighbors and our descendants. If all you want is a place to stick your own poop, you don't need to build a citywide sanitation system.
What's more, we can trade energy for materials. Manufacturing goods so that they gracefully decompose back into the material stream at the end of their lives is energy intensive. Harvesting materials from badly designed goods is also energy intensive. But if once we build out the renewables grid (which will take a lot of materials), we will have all the energy we need (to preserve and re-use our materials).
Our species' historical approach to materials is not (ahem) carved in stone. It is contingent. It has changed. It can change again. It needs to change, because the way we extract materials today is both unjust and unsustainable.
The horrific nature of material extraction under capitalism – and its geopolitics (e.g. "We will coup whoever we want! Deal with it.") – has many made comrades in the climate fight skeptical (or worse, cynical) about a clean energy transition. They do the back-of-the-envelope math about the material budget for electrification, mentally convert that to the number of wildlife preserves, low-income communities, unspoiled habitat and indigenous lands that we would destroy in the process of gathering those materials, and conclude that the whole thing is a farce.
That analysis is important, but it's incomplete. Yes, marshaling all those materials in the way that we do today would be catastrophic. But the point of a climate transition is that we will transition our approach to our planet, our energy, and our materials. That transition can and should challenge all the assumptions underpinning electrification doomerism.
Take the material bill itself: the assumption that a transition will require a linearly scaled quantity of materials includes the assumption that cleantech won't find substantial efficiencies in its material usage. Thankfully, that's a very bad assumption! Cleantech is just getting started. It's at the stage where we're still uncovering massive improvements to production (unlike fossil fuel technology, whose available efficiencies have been discovered and exploited, so that progress is glacial and negligible).
Take copper: electrification requires a lot of copper. But the amount of copper needed for each part of the cleantech revolution is declining faster than the demand for cleantech is rising. Just one example: between the first and second iteration of the Rivian electric vehicle, designers figured out how to remove 1.6 miles of copper wire from each vehicle:
https://insideevs.com/news/722265/rivian-r1s-r1t-wiring/
That's just one iteration and one technology! And yeah, EVs are only peripheral to a cleantech transition; for one thing, geometry hates cars. We're going to have to build a lot of mass transit, and we're going to be realizing these efficiencies with every generation of train, bus, and tram:
https://pluralistic.net/2024/02/29/geometry-hates-uber/#toronto-the-gullible
We have just lived through a massive surge in electrification, with unimaginable quantities of new renewables coming online and a stunning replacement of conventional vehicles with EVs, and throughout that surge, demand for copper remained flat:
https://www.chemanalyst.com/NewsAndDeals/NewsDetails/copper-wire-price-remains-stable-amidst-surplus-supply-and-expanding-mining-25416#:~:text=Global%20Copper%20wire%20Price%20Remains%20Stable%20Amidst%20Surplus%20Supply%20and%20Expanding%20Mining%20Activities
This isn't to say that cleantech is a solved problem. There are many political aspects to cleantech that remain pernicious, like the fact that so many of the cleantech offerings on the market are built around extractive financial arrangements (like lease-back rooftop solar) and "smart" appliances (like heat pumps and induction tops) that require enshittification-ready apps:
https://pluralistic.net/2024/06/26/unplanned-obsolescence/#better-micetraps
There's a quiet struggle going on between cleantech efficiencies and the finance sector's predation, from lease-back to apps to the carbon-credit scam, but many of those conflicts are cashing out in favor of a sustainable future and it doesn't help our cause to ignore those: we should be cheering them on!
https://pluralistic.net/2024/06/12/s-curve/#anything-that-cant-go-on-forever-eventually-stops
Take "innovation." Silicon Valley's string of pump-and-dump nonsense – cryptocurrency, NFTs, metaverse, web3, and now AI – have made "innovation" into a dirty word. As the AI bubble bursts, the very idea of innovation is turning into a punchline:
https://www.wheresyoured.at/burst-damage/
But cleantech is excitingly, wonderfully innovative. The contrast between the fake innovation of Silicon Valley and the real – and vital – innovation of cleantech couldn't be starker, or more inspiring:
https://pluralistic.net/2024/05/30/posiwid/#social-cost-of-carbon
Like the "battery problem." Whenever the renewables future is raised, there's always a doomer insisting that batteries are an unsolved – and unsolvable – problem, and without massive batteries, there's no sense in trying, because the public won't accept brownouts when the sun goes down and the wind stops blowing.
Sometimes, these people are shilling boondoggles like nuclear power (reminder: this is Hiroshima Day):
https://theconversation.com/dutton-wants-australia-to-join-the-nuclear-renaissance-but-this-dream-has-failed-before-209584
Other times, they're just trying to foreclose on the conversation about a renewables transition altogether. But sometimes, these doubts are raised by comrades who really do want a transition and have serious questions about power storage.
If you're one of those people, I have some very good news: battery tech is taking off. Some of that takes the form of wild and cool new approaches. In Finland, a Scottish company is converting a disused copper mine into a gravity battery. During the day, excess renewables hoist a platform piled with tons of rock up a 530m shaft. At night, the platform lowers slowly, driving a turbine and releasing its potential energy. This is incredibly efficient, has a tiny (and sustainable) bill of materials, and it's highly replicable. The world has sufficient abandoned mine-shafts to store 70TWh of power – that's the daily energy budget for the entire planet. What's more, every mine shaft has a beefy connection to the power grid, because you can't run a mine without a lot of power:
https://www.euronews.com/green/2024/02/06/this-disused-mine-in-finland-is-being-turned-into-a-gravity-battery-to-store-renewable-ene
Gravity batteries are great for utility-scale storage, but we also need a lot of batteries for things that we can't keep plugged into the wall, like vehicles, personal electronics, etc. There's great news on that score, too! "The Battery Mineral Loop" is a new report from the Rocky Mountain Institute that describes the path to "circular battery self-sufficiency":
https://rmi.org/wp-content/uploads/dlm_uploads/2024/07/the_battery_mineral_loop_report_July.pdf
The big idea: rather than digging up new minerals to make batteries, we can recycle minerals from dead batteries to make new ones. Remember, energy can be traded for materials: we can expend more energy on designs that are optimized to decompose back into their component materials, or we can expend more energy extracting materials from designs that aren't optimized for recycling.
Both things are already happening. From the executive summary:
The chemistry of batteries is rapidly improving: over the past decade, we've reduced per-using demand for lithium, nickle and cobalt by 60-140%, and most lithium batteries are being recycled, not landfilled.
Within a decade, we'll hit peak mineral demand for batteries. By the mid-2030s, the amount of new "virgin minerals" needed to meet our battery demand will stop growing and start declining.
By 2050, we could attain net zero mineral demand for batteries: that is, we could meet all our energy storage needs without digging up any more minerals.
We are on a path to a "one-off" extraction effort. We can already build batteries that work for 10-15 years and whose materials can be recycled with 90-94% efficiency.
The total quantity of minerals we need to extract to permanently satisfy the world's energy storage needs is about 125m tons.
This last point is the one that caught my eye. Extracting 125m tons of anything is a tall order, and depending on how it's done, it could wreak a terrible toll on people and the places they live.
But one question I learned to ask from Tim Harford and BBC More Or Less is "is that a big number?" 125m tons sure feels like a large number, but it is one seventeenth of the amount of fossil fuels we dig up every year just for road transport. In other words, we're talking about spending the next thirty years carefully, sustainably, humanely extracting about 5.8% of the materials we currently pump and dig every year for our cars. Do that, and we satisfy our battery needs more-or-less forever.
This is a big engineering project. We've done those before. Crisscrossing the world with roads, supplying billions of fossil-fuel vehicles, building the infrastructure for refueling them, pumping billions of gallons of oil – all of that was done in living memory. As Robin Sloan wrote:
Did people say, at the dawn of the automobile: are you kidding me? This technology will require a ubiquitous network of refueling stations, one or two at every major intersection … even if there WAS that much gas in the world, how would you move it around at that scale? If everybody buys a car, you’ll need to build highways, HUGE ones — you’ll need to dig up cities! Madness!
https://www.robinsloan.com/newsletters/room-for-everybody/
That big project cost trillions and required bending the productive capacity of many nations to its completion. It produced a ghastly geopolitics that elevated petrostates – a hole in the ground, surrounded by guns – to kingmakers whose autocrats can knock the world on its ass at will.
By contrast, this giant engineering project is relatively modest, and it will upend that global order, yielding energy sovereignty (and its handmaiden, national resliency) to every country on Earth. Doing it well will be hard, and require that we rethink our relationship to energy and materials, but that's a bonus, not a cost. Changing how we use materials and energy will make all our lives better, it will improve the lives of the living things we share the planet with, and it will strip the monsters who currently control our energy supply of their political, economic, and electric power.

"Heat stored underground in caverns can be set aside in Finland’s summer months to be re-used during frigid winters thanks to a state-of-the-art ‘seasonal energy’ storage facility.
Slated for construction this summer near Helsinki, it will be the largest in the world by all standards and contain enough thermal energy to heat a medium-sized city all winter.
Thermal exchange heating systems, like those built underground, or domestic heat pumps, are seen as the most effective way available of reducing the climate-impact of home heating and cooling.
Their function relies on natural forces or energy recycling to cool down or heat up water and then using it to radiate hot or cold energy into a dwelling.
In Vantaa, Finland’s fourth largest city neighboring the capital of Helsinki, the ambitious Varanto seasonal energy storage project plans to store cheap and environmental friendly waste heat from datacenters, cooling processes, and waste-to-energy assets in underground caverns where it can be used to heat buildings via the district heating network whenever it is needed.
In Finland and other Nordic countries, the heat consumption varies significantly between seasons. Heat consumption in the summertime is only about one-tenth of the peak load consumption during the cold winter months.
Varanto will utilize underground caverns equal in space to two Maddison Square Gardens—over a million cubic meters—filled with water heated by this waste heat and pressure that will allow the water to reach temperatures of up to 300 degrees Fahrenheit without the water boiling or evaporating.
youtube
“The world is undergoing a huge energy transition. Wind and solar power have become vital technologies in the transition from fossil fuels to clean energy,” says Vantaa Energy CEO Jukka Toivonen.
“The biggest challenge of the energy transition so far has been the inability to store these intermittent forms of energy for later use. Unfortunately, small-scale storage solutions, such as batteries or accumulators, are not sufficient; large, industrial-scale storage solutions are needed. Varanto is an excellent example of this, and we are happy to set an example for the rest of the world.” ...
“Two 60-MW electric boilers will be built in conjunction with Varanto,” adds Toivonen. “These boilers will be used to produce heat from renewable electricity when electricity is abundant and cheap. Our heat-producing system will work like a hybrid car: alternating between electricity and other forms of production, depending on what is most advantageous and efficient at the time.”
... Construction of the storage facility’s entrance is expected to start in summer 2024, while it could be operational as early as 2028."

Good News!
Fast fashion has begun going bankrupt
"Consumers are waking up to the environmental impact of the choices they make — including the fact that so much apparel ends up in landfills — and recognizing that a sector based on a buy it/wear it/toss it ethos is unsustainable in both the economic and ecological senses."
//This is the real reason why being woke is being made into a bad thing, its killing consumption driven profits and wasteful culture

From the article:
Almost all new homes in England will be fitted with solar panels during construction within two years, the government will announce after Keir Starmer rejected Tony Blair’s criticism of net zero policies. Housebuilders will be legally required to install solar panels on the roofs of new properties by 2027 under the plans. The policy is estimated to add between £3,000 and £4,000 to building a home but homeowners would save more than £1,000 on their annual energy bills, according to the Times. Labour has set a target of building 1.5m homes by the end of the parliament. The party has promised to decarbonise the electricity grid by 2030 and cut household energy bills by £300 a year.

This episode, Ariel speaks to Sam Nabi about One Million Neighbours, a project bringing together the voices of local non-profits that envisions the future of Waterloo Region once the population has reached one million. Sam discusses the impetus for the project, providing a voice for the voiceless, the issue with grant applications, funding the future, being proactive instead of reactive to harsh policies, and much more. What might an abundant, inclusive, resilient (Ariel says: solarpunk) city look like on the human level? Who lives there, what do they value, and what are their daily lives like? And what does it look like to take action now at the regional/municipal level to ensure that utopian vision?
