Solar power cuts electricity bills and carbon emissions—NZ needs to scale up faster
Solar power is now the cheapest form of electricity in most countries, including New Zealand, and its global uptake is growing exponentially.
So far, New Zealand’s adoption of solar electricity generation has been slower than elsewhere, but it is accelerating quickly. Scaling up installation could help reduce high consumer energy prices and meet New Zealand’s emissions budgets.
Based on current policies, New Zealand is at risk of exceeding its emissions budget for the period from 2026 to 2030, and current plans are insufficient to stay within the subsequent five-year budget up to 2035.
The Climate Change Commission estimates solar combined with battery storage could cut 3.9 million tons of carbon dioxide equivalent emissions between 2031 and 2035.
This is important, as a major part of the government’s plan for cutting emissions over the next five years rested on a carbon capture project at the Kapuni gas field, which seems to have fallen through.
New Zealand is also facing an energy shortage, leading to high electricity prices. But solar could be part of the solution because global reductions in the price of panels mean residential solar is now likely the cheapest option for households.
Solar on the rise
The solar energy reaching Earth each hour is roughly equivalent to a year of humankind’s global energy consumption.
This is not to say our current energy demand should be the target. We need to reduce consumption and use energy more efficiently, even as we continue the shift to more renewable power generation.
But a small fraction of sunlight can go a long way and many countries are taking advantage of this. For example, a consumer-led solar revolution is happening in Pakistan in response to longstanding energy supply problems. This year, solar became the largest source of electricity in Pakistan, surging to 25% of generation from about 5% just three years ago.
The uptake of solar electricity generation is also growing in New Zealand, with a significant uptick in projects for both utility-scale solar farms and household installations.
New Zealand has five large-scale solar farms in operation, and many more in the pipeline (nine at delivery stage, 33 under investigation). We also have more than 65,000 residential solar installations, up from about 7,500 a decade ago.
Despite the rapid growth in recent years, this is still a relatively low adoption rate compared to some other countries, with only about 3-4% of homes having solar installed.
A frequent argument against solar electricity generation is that it is intermittent. But solar panels can use hot water cylinders or batteries to store energy for later use.
And while New Zealand may not get quite as much sunshine as other countries, our existing renewable generation and hydro-lake storage mean we don’t have to invest as much in batteries to buffer intermittent generation.
Also, the flip side of intermittent power sources is that they turn back on—fossil fuels can only be used once.
Managing solar at scale
The energy and emissions-cutting benefits of solar generation are well quantified. Solar panels generate the amount of energy required to manufacture them in less than two years, compared with a total lifetime of about 30 years.
It takes slightly longer to pay back the carbon emissions from their manufacture in New Zealand than elsewhere, because we already have a comparatively high proportion of renewable electricity generation. The carbon payback is faster if solar is used in ways that directly displace fossil fuels (for example, electricity from gas or coal) or if the panels are manufactured in places with low carbon intensity (low emissions per unit of economic activity or energy produced).
There is still work to do. We need to address practical challenges such as effective grid integration and storage, as well as social issues such as ensuring that low-income households aren’t disadvantaged.
Globally, the mining of raw materials for solar panels is a key issue, and we need to ensure ethical supply chains and labor practices associated with materials and manufacture. Ultimately, we need to reach a system where solar panels are recycled to avoid the need for indefinite mining, and to keep panels out of landfills.
This goal looks promising. Solar panel recycling is an active area of research and already possible, although not yet profitable.
As the uptake of solar accelerates, New Zealand should make sure suitable policies are in place. In terms of materials, we should require recycling of solar panels. On the social side, we should ensure support for low-income households and consider incentives for solar installations on rental properties.
Researchers are also exploring next-generation solar power with lower energy and material demands in their manufacture. In most commercial solar panels, the dominant contribution to manufacturing emissions is the silicon “active layer.” There are multiple alternatives to silicon and new technologies use different materials for the active layer.
For example, my research focuses on solution-printable organic semiconductors. These materials absorb light very strongly, which means the active layer is about a thousand times thinner than in a silicon solar panel. A kilogram of material can cover more than 5,000 square meters.
It will take time for these new technologies to reach the same level of development as today’s solar panels. They will likely first enter the market as complementary products such as lightweight installations on low load-bearing surfaces (warehouse roofs) and in building-integrated applications.
Economically viable solar energy generation is a triumph of long-term scientific and engineering development that began in the 1950s and is poised to play a key role in decarbonization. New Zealand needs to think about how to manage this technology at scale if we want to make the most of this opportunity.

What’s an E-Bike? California Wants You to Know
A few months ago, a family came into Pasadena Cyclery in Pasadena, California, for a repair on what they thought was their teenager’s e-bike. “I can’t fix that here,’ Daniel Purnell, a store manager and technician, remembers telling them. “That’s a motorcycle.” The mother got upset. She didn’t realize that what she thought was an e-bike could go much faster, perhaps up to 55 miles per hour.
“There’s definitely an education problem,” Purnell says. In California, bike advocates are pushing a new bill designed to clear up that confusion around what counts as an electric bicycle—and what doesn’t.
It’s a tricky balance. On one hand, backers want to allow riders access to new, faster, and more affordable non-car transportation options, ones that don’t require licenses and are emission-free. On the other hand, people, and especially kids, seem to be getting hurt. E-bike-related injuries jumped more than 1,020 percent nationwide between 2020 and 2024, according to hospital data, though it’s not clear if the stats-keepers can routinely distinguish between e-bikes and their faster, “e-moto” cousins. (Moped and powered-assisted cycle injuries jumped 67 percent in that same period.)
“We’re overdue to have better e-bike regulation,” says California state senator Catherine Blakespear, a Democrat who sponsored the bill and represents parts of North County in San Diego. “This has been an ongoing and growing issue for years.”
Senate Bill 1167 would make it illegal for retailers to label higher-powered, electric-powered vehicles as e-bikes. It would clarify that e-bikes have fully operative pedals and electric motors that don’t exceed 750 watts, enough to hit top speeds between 20 and 28 mph.
“We’re not against these devices,” says Kendra Ramsey, the executive director of the California Bicycle Coalition, which represents riders and is promoting the legislation. “People think they’re e-bikes and they’re not really e-bikes.”
Bill backers say they hope the fix, if it passes, makes a difference, especially for teenagers, who love the freedom that electric motors give them but can get into trouble if something goes wrong at higher speeds. Kids 17 and younger accounted for 20 percent of US e-bike injuries from 2020 to 2024, about in line with the share of the total population. But headlines—and the laws that follow them—have focused on teen injuries and even deaths.
There are no national laws governing e-bike riding. But bike backers spent years moving between states to pass laws that put e-bikes into three classes: Class 1, which have pedal-assist that only works when they’re actually pedaled, and goes up to 20 mph; Class 2, which have throttles that work without pedaling but still only reach 20 mph; and Class 3, which use pedal-assist to move up to 28 mph. Plenty of states and cities restrict the most powerful Class 3 bikes to people older than 16. (In a complicated twist, some e-bikes have different “modes,” allowing riders to toggle between Class 2 and Class 3.)
Last year, researchers visited 19 San Francisco Bay Area middle and high schools and found that 88 percent of the electric two-wheeled devices parked there were so high-powered and high-speed that they didn’t comply with the three-class system at all.
E-bikes have clearly struck a chord with state policymakers: At least 10 bills introduced this year deal with e-bikes, according to Ramsey.
Some bike advocates believe injuries have less to do with e-bikes than “e-motos,” a category that’s less likely to appear in retail stores or the sort of social media ads attracting teens to the tech. These have more powerful motors and can travel in excess of 30 mph. Vehicles, like the Surron Ultra Bee, which can hit top speeds of 55 mph, or Tuttio ICT, which can hit 50, are often marketed by retailers as “electric bikes.” Because so many sales happen online, it can be hard for people, and especially parents, to know what they’re getting into.

OpenAI Fires an Employee for Prediction Market Insider Trading
OpenAI has fired an employee following an investigation into their activity on prediction market platforms including Polymarket, WIRED has learned.
OpenAI CEO of Applications, Fidji Simo, disclosed the termination in an internal message to employees earlier this year. The employee, she said, “used confidential OpenAI information in connection with external prediction markets (e.g. Polymarket).”
“Our policies prohibit employees from using confidential OpenAI information for personal gain, including in prediction markets,” says spokesperson Kayla Wood. OpenAI has not revealed the name of the employee or the specifics of their trades.
Evidence suggests that this was not an isolated event. Polymarket runs on the Polygon blockchain network, so its trading ledger is pseudonymous but traceable. According to an analysis by the financial data platform Unusual Whales, there have been clusters of activities, which the service flagged as suspicious, around OpenAI-themed events since March 2023.
Unusual Whales flagged 77 positions in 60 wallet addresses as suspected insider trades, looking at the age of the account, trading history, and significance of investment, among other factors. Suspicious trades hinged on the release dates of products like Sora, GPT-5, and the ChatGPT Browser, as well as CEO Sam Altman’s employment status. In November 2023, two days after Altman was dramatically ousted from the company, a new wallet placed a significant bet that he would return, netting over $16,000 in profits. The account never placed another bet.
The behavior fits into patterns typical of insider trades. “The tell is the clustering. In the 40 hours before OpenAI launched its browser, 13 brand-new wallets with zero trading history appeared on the site for the first time to collectively bet $309,486 on the right outcome,” says Unusual Whales CEO Matt Saincome. “When you see that many fresh wallets making the same bet at the same time, it raises a real question about whether the secret is getting out.”
Prediction markets have exploded in popularity in recent years. These platforms allow customers to buy “event contracts” on the outcomes of future events ranging from the winner of the Super Bowl to the daily price of Bitcoin to whether the United States will go to war with Iran. There are a wide array of markets tied to events in the technology sector; you can trade on what Nvidia’s quarterly earnings will be, or when Tesla will launch a new car, or which AI companies will IPO in 2026.
As the platforms have grown, so have concerns that they allow traders to profit from insider knowledge. “This prediction market world makes the Wild West look tame in comparison,” says Jeff Edelstein, a senior analyst at the betting news site InGame. “If there’s a market that exists where the answer is known, somebody’s going to trade on it.”
Earlier this week, Kalshi announced that it had reported several suspicious insider trading cases to the Commodity Futures Trading Commission, the government agency overseeing these markets. In one instance, an employee of the popular YouTuber Mr. Beast was suspended for two years and fined $20,000 for making trades related to the streamer’s activities; in another, the far-right political candidate Kyle Langford was banned from the platform for making a trade on his own campaign. The company also announced a number of initiatives to prevent insider trading and market manipulation.
While Kalshi has heavily promoted its crackdown on insider trading, Polymarket has stayed silent on the matter. The company did not return requests for comments.
In the past, major trades on technology-themed markets have sparked speculation that there are Big Tech employees profiting by using their insider knowledge to gain an edge. One notorious example is the so-called “Google whale,” a pseudonymous account on Polymarket that made over $1 million trading on Google-related events, including a market on who the most-searched person of the year would be in 2025. (It was the singer D4vd, who is best known for his connection to an ongoing murder investigation after a young fan’s remains were found in a vehicle registered to him.)

Wall Street Has AI Psychosis
Before last week the name Alap Shah didn’t ring a bell for many people. The 45-year-old financial analyst and tech entrepreneur had spent the past two decades working in relative obscurity. Then last weekend he coauthored a blog with the research firm Citrini titled “The 2028 Global Intelligence Crisis.” It was a “thought exercise” about the impacts of artificial intelligence, and it predicted that in June of that year, AI would jack up unemployment past 10 percent and force the Dow down, down, down. Writing in a confident, Nostradamic tone—as if auditioning for starring roles in the next Michael Lewis book—the authors painted a picture of a flywheel in reverse: AI agents take jobs from workers, people spend less, and struggling corporations conduct layoffs on top of layoffs.
There wasn’t much in it that hadn’t been previously heard, or speculated about. Tech leaders like Anthropic CEO Dario Amodei have already estimated that half the entry level white collar jobs will soon be gone, and earlier this year, Anthropic’s release of new agentic tools spurred a Wall Street selloff. Nonetheless the report hit with the force of the blizzard blowing through lower Manhattan. When the closing chimes sounded on the New York Stock Exchange, the Dow was down 800 points. The name Alap Shah was now ringing bells.
The achievement is less impressive than it seems. Wall Street, like the rest of us, is in a persistent state of anxiety about AI, and it doesn’t take much to trigger a mini-panic. Financial markets don’t necessarily map to reality, but the jitters reflect a wider disquiet. The AI future is in a William Gibson zone—it’s here, but unevenly distributed—and the news from those already living in the agent-packed, AI code-writing universe is both exciting and unsettling. Emphasis on unsettling.
No one—no one!—knows exactly how AI will impact the economy, but clearly it will be significant. Right now stocks are soaring, so it seems to make sense to keep the party going. But then along comes the latest doom manifesto, or a paper indicating that a traditional business sector might be threatened by AI, and suddenly money managers are reminded that the biggest issue of our time is totally unresolved. Case in point: earlier this month, a tiny company (valuation under $6 million) that had previously sold karaoke machines pivoted to AI-powered shipping logistics and put out a report saying that it had discovered some efficiencies in loading semi-trucks. That was enough to erase billions of dollars from the share prices of several major logistics companies, none of which had karaoke experience.
After it did its job on Wall Street, the Citrini report came under considerable fire. Critics climbed over each other to proclaim its flimsiness. For one thing, they pointed out, AI has had very little discernable impact on the economy so far. Others cited the long history of resilience after technological upheavals. A mocking response by the respected trading firm Citadel Securities read, “For AI to produce a sustained negative demand shock, the economy must see a material acceleration in adoption, experience near-total labor substitution, no fiscal response, negligible investment absorption, and unconstrained scaling of compute.”
The most withering critiques disputed the report’s contention that much of the economy involves non-productive “rent-seeking” by middlemen and market makers, taking advantage of the laziness of the general population. When everyone has a few dozen AI agents working on their behalf, writes Shah, consumers will be able to effortlessly find the best goods for the best prices. Apps will be rendered unnecessary—just type what you want into the LLM and an army of agents will do everything for you. The “poster child” for this phenomenon, Shah says, is DoorDash. Instead of being limited to the restaurants on the app, consumers will send out AI agents to find their ideal meal options, contracting directly with restaurants and delivery people—no apps needed. Zero friction! The DoorDashes of the world are avocado toast!
