2024 CNBC Disruptor 50: #31 Zum CEO on electrifying American school buses

The nightlife of school buses is about to get more interesting.

Zum, which provides student transportation including EV buses to 4,000 schools across the country, is partnering with the Oakland Unified School District to start selling power stored in EV batteries back to the California utility grid.

Oakland is the first school district in the U.S. to go fully electric with its buses, 74 in all, and will now be the first to test the concept of V2G (vehicle to grid) bidirectional charging. In effect, instead of the one-way charge into the vehicle, the school buses will be able to send their battery power back to the grid through Zum charging infrastructure.

Zum estimates that 2.1 gigawatt hours of energy can be sent from batteries back to the California grid annually. The company’s goal is to add 10,000 bidirectional EV school buses across the U.S. with 300 gigawatt hours of energy available to power grids each year. San Francisco Unified and Los Angeles Unified, much larger districts than Oakland, are expected to follow, Zum said. It also works with school districts in California, Colorado, Connecticut, Illinois, Maryland, Massachusetts, Missouri, Nebraska, Pennsylvania, Tennessee, Texas, Washington, Utah, and Virginia.

There have been pilots across the country to test school bus V2G business models, but Zum says the time has come to move beyond the test phase.

“We at Zum strongly believe it is time to move beyond pilots and deploy sustainability solutions at scale. Converting the Oakland Unified school bus fleet to 100% electric with VPP [virtual power plant] capability is the right step in that direction,” said Ritu Narayan, founder and CEO of Zum, in a release.

In a CNBC interview later on Wednesday, Narayan referred to the school bus as “the largest battery on wheels,” with four to six times the battery of a Tesla.

According to Zum, the 27 million students moved across the country to and from schools twice daily is the largest mass transit system in the country. The roughly 500,000 school buses are mostly diesel, contributing to emissions. Zum has the goal of being a net-zero transport provider.

Pacific Gas and Electric, which is based in Oakland, has partnered with Zum to enable its bidirectional charging station for EV buses in Oakland.

The concept is considered a strong one given the fact that school buses are not in use during peak energy demand hours, for example, between 5 p.m. and 10 p.m. This allows the buses, and their owners, to execute an energy arbitrage trade: charging up for their core daily task of moving students when energy prices are lower, and feeding battery storage back onto the grid when utilities will pay more for it per kilowatt/hour. As owner of the buses in use in Oakland, Zum will be the one to receive revenue from the grid deal, but in other cases where school districts own the buses, they can generate revenue. In some cases, the revenue from power sales could be split.

Narayan told CNBC that the school bus is an “ideal asset to be electrified” due to the battery and its predictable local pattern of use outside of peak hours.

Ram Ambatipudi, senior vice president of business development at EV Connect, which provides EV charging solutions, said the school bus model is one of the most promising in the area of using EV battery storage in a bidirectional nature. He said one of the biggest challenges is getting utilities to set a predetermined rate schedule that will allow for the arbitrage play across power markets, generating the revenue opportunity for the battery owners.

“There aren’t a lot of established rate schedules,” Ambatipudi said. In addition, a lot has to go right to make the model work and is still being tested. “It’s been more of a pilot level because that interplay has to happen between the vehicle charging station hardware, and software management of the station, and the backfeeding into grid and having the economic benefit paid out by the utility. “Those market developments have yet to come,” he said.

EV school buses today are two to three times as expensive as traditional buses, and the V2G model of selling energy back to the grid is part of the economic plan to make the transport technology more cost-effective for owners over time — EV battery costs are also declining while their efficiency rises.

The idea is similar in some ways to how owners of rooftop solar systems have been able to feed power back onto the grid in some markets, but in recent years, there has been pushback against these “net metering” relationships, especially in California. With buses, though, there is one key difference: the buses are not in use during the most important times of the day for the grid to have more power, and the buses can recharge at off-peak demand hours. Many rooftop solar power owners were selling energy supply back onto the grid when it was less needed.

And the arbitrage economics make sense: bus owners charge the vehicles during the lowest-cost periods so they can allocate excess battery power to be sold back into the grid when it is at its highest economic value.

There are many applications to take stored power in EV batteries and use as a supply, such as Ford pitching its F-150 Lightning EV as a home backup power source for when the grid is down and saying that has shown a surprising level of consumer appeal. But the school bus model may be the most effective at the largest scale.

“The low-hanging fruit from what I’ve seen is the school bus model,” Ambatipudi said. It’s not just the cycle of dropping off kids during the morning and then remaining idle at a depot during the middle part of day, and then cycling again in the afternoon and early evening into idle state again. During summer months, the buses are largely idle. “Buses can be used as essentially arbitrage devices to charge when power is cheap and discharge when needed,” he said.

Etsy touts 'shopping domestically' as Trump tariffs threaten price increases for imports

Etsy is trying to make it easier for shoppers to purchase products from local merchants and avoid the extra cost of imports as President Donald Trump’s sweeping tariffs raise concerns about soaring prices.

In a post to Etsy’s website on Thursday, CEO Josh Silverman said the company is “surfacing new ways for buyers to discover businesses in their countries” via shopping pages and by featuring local sellers on its website and app.

“While we continue to nurture and enable cross-border trade on Etsy, we understand that people are increasingly interested in shopping domestically,” Silverman said.

Etsy operates an online marketplace that connects buyers and sellers with mostly artisanal and handcrafted goods. The site, which had 5.6 million active sellers as of the end of December, competes with e-commerce juggernaut Amazon, as well as newer entrants that have ties to China like Temu, Shein and TikTok Shop.

By highlighting local sellers, Etsy could relieve some shoppers from having to pay higher prices induced by President Trump’s widespread tariffs on trade partners. Trump has imposed tariffs on most foreign countries, with China facing a rate of 145%, and other nations facing 10% rates after he instituted a 90-day pause to allow for negotiations. Trump also signed an executive order that will end the de minimis provision, a loophole for low-value shipments often used by online businesses, on May 2.

Temu and Shein have already announced they plan to raise prices late next week in response to the tariffs. Sellers on Amazon’s third-party marketplace, many of whom source their products from China, have said they’re considering raising prices.

Silverman said Etsy has provided guidance for its sellers to help them “run their businesses with as little disruption as possible” in the wake of tariffs and changes to the de minimis exemption.

Before Trump’s “Liberation Day” tariffs took effect, Silverman said on the company’s fourth-quarter earnings call in late February that he expects Etsy to benefit from the tariffs and de minimis restrictions because it “has much less dependence on products coming in from China.”

“We’re doing whatever work we can do to anticipate and prepare for come what may,” Silverman said at the time. “In general, though, I think Etsy will be more resilient than many of our competitors in these situations.”

Still, American shoppers may face higher prices on Etsy as U.S. businesses that source their products or components from China pass some of those costs on to consumers.

Etsy shares are down 17% this year, slightly more than the Nasdaq.

Google hit with second antitrust blow, adding to concerns about future of ads business

Google hit with second antitrust blow, adding to concerns about future of ads business

Google’s antitrust woes are continuing to mount, just as the company tries to brace for a future dominated by artificial intelligence.

On Thursday, a federal judge ruled that Google held illegal monopolies in online advertising markets due to its position between ad buyers and sellers.

The ruling, which followed a September trial in Alexandria, Virginia, represents a second major antitrust blow for Google in under a year. In August, a judge determined the company has held a monopoly in its core market of internet search, the most-significant antitrust ruling in the tech industry since the case against Microsoft more than 20 years ago. 

Google is in a particularly precarious spot as it tries to simultaneously defend its primary business in court while fending off an onslaught of new competition due to the emergence of generative AI, most notably OpenAI’s ChatGPT, which offers users alternative ways to search for information. Revenue growth has cooled in recent years, and Google also now faces the added potential of a slowdown in ad spending due to economic concerns from President Donald Trump’s sweeping new tariffs.

Parent company Alphabet reports first-quarter results next week. Alphabet’s stock price dipped more than 1% on Thursday and is now down 20% this year.

Why Google's antitrust woes endangers its AI momentum

In Thursday’s ruling, U.S. District Judge Leonie Brinkema said Google’s anticompetitive practices “substantially harmed” publishers and users on the web. The trial featured 39 live witnesses, depositions from an additional 20 witnesses and hundreds of exhibits.

Judge Brinkema ruled that Google unlawfully controls two of the three parts of the advertising technology market: the publisher ad server market and ad exchange market. Brinkema dismissed the third part of the case, determining that tools used for general display advertising can’t clearly be defined as Google’s own market. In particular, the judge cited the purchases of DoubleClick and Admeld and said the government failed to show those “acquisitions were anticompetitive.”

“We won half of this case and we will appeal the other half,” Lee-Anne Mulholland, Google’s vice president or regulatory affairs, said in an emailed statement. “We disagree with the Court’s decision regarding our publisher tools. Publishers have many options and they choose Google because our ad tech tools are simple, affordable and effective.”

Attorney General Pam Bondi said in a press release from the DOJ that the ruling represents a “landmark victory in the ongoing fight to stop Google from monopolizing the digital public square.”

Potential ad disruption

If regulators force the company to divest parts of the ad-tech business, as the Justice Department has requested, it could open up opportunities for smaller players and other competitors to fill the void and snap up valuable market share. Amazon has been growing its ad business in recent years.

Meanwhile, Google is still defending itself against claims that its search has acted as a monopoly by creating strong barriers to entry and a feedback loop that sustained its dominance. Google said in August, immediately after the search case ruling, that it would appeal, meaning the matter can play out in court for years even after the remedies are determined.

The remedies trial, which will lay out the consequences, begins next week. The Justice Department is aiming for a break up of Google’s Chrome browser and eliminating exclusive agreements, like its deal with Apple for search on iPhones. The judge is expected to make the ruling by August.

After the ad market ruling on Thursday, Gartner’s Andrew Frank said Google’s “conflicts of interest” are apparent by how the market runs.

“The structure has been decades in the making,” Frank said, adding that “untangling that would be a significant challenge, particularly since lawyers don’t tend to be system architects.”

However, the uncertainty that comes with a potentially years-long appeals process means many publishers and advertisers will be waiting to see how things shake out before making any big decisions given how much they rely on Google’s technology.

“Google will have incentives to encourage more competition possibly by loosening certain restrictions on certain media it controls, YouTube being one of them,” Frank said. “Those kind of incentives may create opportunities for other publishers or ad tech players.”

A date for the remedies trial hasn’t been set.

Damian Rollison, senior director of market insights for marketing platform Soci, said the revenue hit from the ad market case could be more dramatic than the impact from the search case.

“The company stands to lose a lot more in material terms if its ad business, long its main source of revenue, is broken up,” Rollison said in an email. “Whereas divisions like Chrome are more strategically important.”

Discord sued by New Jersey over child safety features

The New Jersey attorney general sued Discord on Thursday, alleging that the company misled consumers about child safety features on the gaming-centric social messaging app.

The lawsuit, filed in the New Jersey Superior Court by Attorney General Matthew Platkin and the state’s division of consumer affairs, alleges that Discord violated the state’s consumer fraud laws.

Discord did so, the complaint said, by allegedly “misleading children and parents from New Jersey” about safety features, “obscuring” the risks children face on the platform and failing to enforce its minimum age requirement.

“Discord’s strategy of employing difficult to navigate and ambiguous safety settings to lull parents and children into a false sense of safety, when Discord knew well that children on the Application were being targeted and exploited, are unconscionable and/or abusive commercial acts or practices,” lawyers wrote in the legal filing.

They alleged that Discord’s acts and practices were “offensive to public policy.”

A Discord spokesperson said in a statement that the company disputes the allegations and that it is “proud of our continuous efforts and investments in features and tools that help make Discord safer.”

“Given our engagement with the Attorney General’s office, we are surprised by the announcement that New Jersey has filed an action against Discord today,” the spokesperson said.

One of the lawsuit’s allegations centers around Discord’s age-verification process, which the plaintiffs believe is flawed, writing that children under thirteen can easily lie about their age to bypass the app’s minimum age requirement.

The lawsuit also alleges that Discord misled parents to believe that its so-called Safe Direct Messaging feature “was designed to automatically scan and delete all private messages containing explicit media content.” The lawyers claim that Discord misrepresented the efficacy of that safety tool.

“By default, direct messages between ‘friends’ were not scanned at all,” the complaint stated. “But even when Safe Direct Messaging filters were enabled, children were still exposed to child sexual abuse material, videos depicting violence or terror, and other harmful content.”

The New Jersey attorney general is seeking unspecified civil penalties against Discord, according to the complaint.

The filing marks the latest lawsuit brought by various state attorneys general around the country against social media companies.

In 2023, a bipartisan coalition of over 40 state attorneys general sued Meta over allegations that the company knowingly implemented addictive features across apps like Facebook and Instagram that harm the mental well being of children and young adults.

The New Mexico attorney general sued Snap in Sep. 2024 over allegations that Snapchat’s design features have made it easy for predators to easily target children through sextortion schemes.

The following month, a bipartisan group of over a dozen state attorneys general filed lawsuits against TikTok over allegations that the app misleads consumers that its safe for children. In one particular lawsuit filed by the District of Columbia’s attorney general, lawyers allege that the ByteDance-owned app maintains a virtual currency that “substantially harms children” and a  livestreaming feature that “exploits them financially.”

In January 2024, executives from Meta, TikTok, Snap, Discord and X were grilled by lawmakers during a senate hearing over allegations that the companies failed to protect children on their respective social media platforms.
