Amid renewable-energy boom, study explores options for electricity market
Renewable energy sources like wind and solar generation now account for over 20% of electricity in the U.S., and keep growing after large-scale production has more than doubled since 2000.
Still, high-profile power failures illustrate persistent challenges from the lack of available capacity to provide enough energy at times of need, said Chiara Lo Prete, an associate professor of energy economics in the John and Willie Family Department of Energy and Mineral Engineering at Penn State.
The issue isn’t insufficient generation, but an unreliable ability to deliver ample power when customer use spikes, particularly where renewable resources and natural gas dominate power production, Lo Prete said. To better support the clean-energy transition, she and colleagues at a Washington, D.C.-based nonprofit recently studied 11 electricity market design proposals under consideration by grid operators. These designs put forward different approaches to guide energy generation and sources, as well as use across every sector of the energy market.
The proposals, yet to be tested in the market, range from a modest variation on current market designs to a complete overhaul. Researchers organized proposals into five categories from least to most dramatic, including concepts for long-term contract auctions and a two-pronged approach combining long- and short-term markets.
“Market structures should allow utility operators to recover both fixed and variable costs so they foster greater system reliability overall,” Lo Prete said.
Findings published in the journal Energy Economics spotlight key questions confronting utility decision makers and can shape more research into adjusting electricity markets. Lo Prete explained that forecasting overall demand—expected to see historic growth of 25% by 2030 and 78% by 2050—will be especially difficult as transportation electrifies and more data centers come online.
Mandatory “forward contracts,” or advance obligations by distributors to purchase specific amounts of electricity from power generators, could help support investments in resources that are instrumental in meeting decarbonization objectives, she said.
Lo Prete noted the February 2021 system failure in Texas that left more than 4.5 million homes without power; rolling outages in California in August 2020; and near-blackouts, also in the Golden State, in September 2022. In each instance, the underlying problem was a lack of accessible energy in the moment of greatest demand, she said.
Such situations have led grid operators to weigh the market approaches reviewed by researchers in their study, Lo Prete said. Reforms on the table would attempt to accommodate ongoing shifts in power generation, whether through longer-term auctioning of future electricity supplies, more centralized resource planning or other mechanisms like so-called “swing contracts.” They seek to ensure the availability of power production capabilities for dispatch in future operating periods.
“When the markets were restructured in the late 1990s, the energy system was very different from the one we have today,” Lo Prete said.
At that point, the system centered on thermal power plants driven by fossil fuels and nuclear energy. Utility markets today aren’t structured to integrate and sustain the renewable sources and large-scale electricity storage that have taken root since then.
Still, maintaining a range of power generation is vital, as older facilities like coal-powered plants contribute less to the power supply but remain important to consistent service, Lo Prete said. Last year, coal accounted for 8% of primary energy consumption nationally, down from 23% in 2000, according to a congressional report.
For their study, Lo Prete and her research partners at Resources for the Future (RFF) examined market proposals to assess energy affordability, efficiency, energy adequacy and other factors. Lo Prete, a faculty associate of the EMS Energy Institute and the Institute of Energy and the Environment and a Wilson Faculty Fellow at Penn State, completed a sabbatical at RFF ahead of the paper’s publication.
Among their conclusions, researchers found the organization of regulatory oversight makes it more difficult to incorporate clean-energy policy into electricity markets. Those “forward contracts” requiring specific electricity purchases could promote energy storage and power systems’ overall ability to fulfill customer needs, they found.
At the same time, the authors said it was tough to make recommendations or endorse one proposal over others, in part because the concepts were in different stages of development. Researchers cited specific concerns over inadequate investment incentives in current energy markets.
The authors also urged cooperation among energy-market researchers, encouraging them to make proposals accessible to broad audiences and facilitate input and feedback from those constituents. Communication will help researchers understand concerns and possible points of confusion, they said.
At Resources for the Future, contributing to the paper were Karen Palmer, senior fellow and director of the Electric Power Program, and associate fellow Molly Robertson.

Onnit’s Instant Melatonin Spray Is the Easiest Part of My Nightly Routine
I’ve always approached taking melatonin supplements with skepticism. They seem to help every once in a while, but your brain is already making melatonin. Beyond that, I am not a fan of the sickly-sweet tablets, gummies, and other forms of melatonin I’ve come across. No one wants a bad taste in their mouth when they’re supposed to be drifting off to sleep.
This is where Onnit’s Instant Melatonin Spray comes in. Fellow WIRED reviewer Molly Higgins first gave it a go, and reported back favorably. This spray comes in two flavors, lavender and mint, and is sweetened with stevia. While I wouldn’t consider it a gourmet taste, I appreciate that it leans more into herbal components known for sleep and relaxation.
Keep in mind that melatonin is meant to be a sleep aid, not a cure-all. That being said, one serving of this spray has 3 milligrams of melatonin, which takes about six pumps to dispense. While 3 milligrams may not seem like a lot to really kickstart your circadian rhythm, it’s actually the ideal dosage to get your brain’s wind-down process kicked off. Some people can do more (but don’t go over 10 milligrams!), some less, but based on what experts have relayed to me, this is the preferable amount.
A couple of reminders for any supplement: consult your doctor if and when you want to incorporate anything, melatonin included, into your nighttime regimen. Your healthcare provider can help confirm that you’re not on any medications where adding a sleep aid or supplement wouldn’t feel as effective. Onnit’s Instant Melatonin Spray is International Genetically Modified Organism Evaluation and Notification certified (IGEN) to verify that it uses truly non-GMO ingredients.
Apart from that, there may be some trial and error on the ideal amount for you, and how much time it takes to kick in. Some may feel the melatonin sooner than others. For my colleague Molly, it took about an hour. Melatonin can’t do all the heavy lifting, so make sure you’re ready to go to bed when you take it, and that your sleep space is set up for sleep success, down to your mattress, sheets, and pillows.

I Tested Bosch’s New Vacuum Against Shark and Dyson. It Didn’t Beat Them
There’s a lever on the back for this compression mechanism that you manually press down and a separate button to open the dustbin at the bottom. You can use the compression lever when it’s both closed and open. It did help compress the hair and dust while I was vacuuming, helping me see if I had really filled the bin, though at a certain point it doesn’t compress much more. It was helpful to push debris out if needed too, versus the times I’ve had to stick my hand in both the Dyson and Shark to get the stuck hair and dust out. Dyson has this same feature on the Piston Animal V16, which is due out this year, so I’ll be curious to see which mechanism is better engineered.
Bendable Winner: Shark

If you’re looking for a vacuum that can bend to reach under furniture, I prefer the Shark to the Bosch. Both have a similar mechanism and feel, but the Bosch tended to push debris around when I was using it with an active bend, while the Shark managed to vacuum up debris I couldn’t get with the Bosch without lifting it and placing it on top of that particular debris (in this case, rogue cat kibble).
Accessory Winner: Dyson
Dyson pulls ahead because the Dyson Gen5 Detect comes with three attachments and two heads. You’ll get a Motorbar head, a Fluffy Optic head, a hair tool, a combination tool, and a dusting and crevice tool that’s actually built into the stick tube. I love that it’s built into the vacuum so that it’s one less separate attachment to carry around, and it makes me more likely to use it.
But Bosch does well in this area, too. You’ll get an upholstery nozzle, a furniture brush, and a crevice nozzle. It’s one more attachment than you’ll get with Shark, and Bosch also includes a wall mount that you can wire the charging cord into for storage and charging, and you can mount two attachments on it. But I will say, I like that Shark includes a simple tote bag to store the attachments in. The rest of my attachments are in plastic bags for each vacuum, and keeping track of attachments is the most annoying part of a cordless vacuum.
Build Winner: Tie

All three of these vacuums have a good build quality, but each one feels like it focuses on something different. Bosch feels the lightest of the three and stands up the easiest on its own, but all three do need something to lean against to stay upright. The Dyson is the worst at this; it also needs a ledge or table wedged under the canister, or it’ll roll forward and tip over. The Bosch has a sleek black look and a colorful LED screen that will show you a picture of carpet or hardwood depending on what mode it’s vacuuming in. The vacuum head itself feels like the lightest plastic of the bunch, though.

Right-Wing Gun Enthusiasts and Extremists Are Working Overtime to Justify Alex Pretti’s Killing
Brandon Herrera, a prominent gun influencer with over 4 million followers on YouTube, said in a video posted this week that while it was unfortunate that Pretti died, ultimately the fault was his own.
“Pretti didn’t deserve to die, but it also wasn’t just a baseless execution,” Herrera said, adding without evidence that Pretti’s purpose was to disrupt ICE operations. “If you’re interfering with arrests and things like that, that’s a crime. If you get in the fucking officer’s way, that will probably be escalated to physical force, whether it’s arresting you or just getting you the fuck out of the way, which then can lead to a tussle, which, if you’re armed, can lead to a fatal shooting.” He described the situation as “lawful but awful.”
Herrera was joined in the video by former police officer and fellow gun influencer Cody Garrett, known online as Donut Operator.
Both men took the opportunity to deride immigrants, with Herrera saying “every news outlet is going to jump onto this because it’s current thing and they’re going to ignore the 12 drunk drivers who killed you know, American citizens yesterday that were all illegals or H-1Bs or whatever.”
Herrera also referenced his “friend” Kyle Rittenhouse, who has become central to much of the debate about the shooting.
On August 25, 2020, Rittenhouse, who was 17 at the time, traveled from his home in Illinois to a protest in Kenosha, Wisconsin, brandishing an AR-15-style rifle, claiming he was there to protect local businesses. He killed two people and shot another in the arm that night.
Critics of ICE’s actions in Minneapolis quickly highlighted what they saw as the hypocrisy of the right’s defense of Rittenhouse and attacks on Pretti.
“Kyle Rittenhouse was a conservative hero for walking into a protest actually brandishing a weapon, but this guy who had a legal permit to carry and already had had his gun removed is to some people an instigator, when he was actually going to help a woman,” Jessica Tarlov, a Democratic strategist, said on Fox News this week.
Rittenhouse also waded into the debate, writing on X: “The correct way to approach law enforcement when armed,” above a picture of himself with his hands up in front of police after he killed two people. He added in another post that “ICE messed up.”
The claim that Pretti was to blame was repeated in private Facebook groups run by armed militias, according to data shared with WIRED by the Tech Transparency Project, as well as on extremist Telegram channels.
“I’m sorry for him and his family,” one member of a Facebook group called American Patriots wrote. “My question though, why did he go to these riots armed with a gun and extra magazines if he wasn’t planning on using them?”
Some extremist groups, such as the far-right Boogaloo movement, have been highly critical of the administration’s comments on being armed at a protest.
“To the ‘dont bring a gun to a protest’ crowd, fuck you,” one member of a private Boogaloo group wrote on Facebook this week. “To the fucking turn coats thinking disarming is the answer and dont think it would happen to you as well, fuck you. To the federal government who I’ve watched murder citizens just for saying no to them, fuck you. Shall not be infringed.”
