Blake Dollier spoke excitedly as he watched the construction crews pulverize concrete along a quarter-mile stretch of U.S. Highway 52 where it passes through West Lafayette, Indiana.

Soon, the Indiana Department of Transportation, or INDOT, where Dollier works as the public relations director, will install a series of copper coils under the highway’s surface to test a new technology Purdue University researchers developed that can provide power to electric vehicles wirelessly as they drive past.

“Wouldn’t it really be something if we could just drive over the road and catch your charge for your vehicle as you drive across it?” Dollier said during a phone interview, watching the progress from the parking lot of one of the department’s satellite offices in West Lafayette.

The state began construction of its new pilot project this month, and officials say they believe it could spur greater adoption of EVs and redefine the way people think about them. The project, they said, which is being done in partnership with Purdue and the engine manufacturer Cummins Inc., will be capable of providing power to vehicles even as they cruise by at speeds of up to 65 miles per hour.

Ultimately, Purdue researchers and state officials hope the project will open up EVs to a wider customer base, largely by reducing battery costs and quelling concerns over range anxiety — the fear that an electric vehicle will run out of juice before reaching its destination. One in four U.S adults say that they would seriously consider buying an EV for their next purchase, but more than half of those who don’t want to buy an electric vehicle blame range anxiety, according to a survey conducted by AAA last year.

While Indiana’s project wouldn’t be the first “dynamic EV charger” in the nation — Detroit installed a similar pilot project on a residential road last fall — it would be the first time the technology was installed on a highway.

If successful, the technology could also help to electrify long-haul trucks, which are among the most difficult vehicles to decarbonize, said Nadia Gkritza, a civil engineering professor at Purdue University and the project’s lead researcher. 

That’s because heavy-duty trucks would require significantly larger batteries due to their size, weight and the long distances they tend to travel, Gkritza said. However, she said, if they could receive power as they drive, it would allow those vehicles to carry smaller batteries, lowering overall costs and reducing the number of stops to recharge.

“Really the possibilities are endless,” INDOT’s Dollier said. “And we’re just hopeful that this is something that can really benefit a lot of people here in the state of Indiana and maybe even across the country going forward.”

INDOT says the pilot project should be complete by next summer, though private vehicles won’t be able to use it — at least not yet. Cars and trucks must be equipped with special receivers for the wireless charging to work, meaning current models are incompatible. The coils are installed underground and use magnetic fields to deliver the electricity wirelessly. Each coil only activates when a receiver is above it, Purdue researchers say, so the infrastructure won’t pose a threat to pedestrians, animals or other vehicles.

Kaylee Dann, executive director of Greater Indiana Clean Cities, a clean energy advocacy nonprofit that isn’t involved with the project, agrees that the new technology could spur greater EV adoption in Indiana and nationwide. In fact, she said, the project is coming at a time when more and more Hoosiers are choosing to go electric.

While Indiana’s overall EV adoption rates still pale in comparison to California and other leaders in the EV market, the state saw an astounding 1,200 percent increase in registered electric vehicles between 2016 and 2022, according to a state report published last year. Some 24,000 electric vehicles were registered in Indiana last year alone, according to the state’s Office of Energy Development.

Dann believes that leaning into EVs has been a smart financial move by the state as the nation pivots to cleaner transportation options. Two recent federal policies — the 2022 Inflation Reduction Act and the Environmental Protection Agency’s new tailpipe pollution standards, finalized last month — are expected to dramatically increase domestic production of EVs nationwide in the coming years.

Indiana is already experiencing some of that economic gain. According to a state report published last September, Indiana has received about $8.2 billion in investments related to EV production since 2021. Those include a $3 billion investment by General Motors and Samsung to manufacture EV batteries in the city of New Carlisle and an $803 million investment by Toyota to expand its EV production in the city of Princeton.

“We’ve seen a lot of investment from manufacturers,” Dann said. “So we’re gonna see a big influx of EVs being produced in the state.”

But the biggest benefits to the state could be environmental.

In its annual State of the Air Report, the American Lung Association ranked the Indianapolis metro area the 10th worst city in the nation for year-round particulate matter pollution known as PM2.5. Regular exposure to PM2.5, which is produced any time something combusts, has been linked to increased health risks, including greater risk of asthma attacks, cardiovascular and lung diseases and even premature death. 

Because EVs draw power from batteries, not from burning fuel, a higher adoption of them would lead to better air quality for any state. Gkritza said that reducing air pollution is one of the broader goals of Indiana’s pilot project. “Greenhouse gas emissions, air quality, these are really bad across those freight corridors, transit corridors — we have communities that are negatively impacted by freight movement,” she said.

More EVs also means fewer greenhouse gas emissions, Dann said, which helps to slow climate change. Transportation is America’s largest source of greenhouse gas emissions, according to the EPA, making up nearly a third of the country’s carbon footprint.

In Indiana alone, EVs contribute 60 percent less carbon pollution than their fossil fuel counterparts, Dann said, despite the fact that the state’s electricity — the fuel for EVs — is predominantly produced by coal-fired power plants. More than half of the state’s electricity in 2021 was generated by coal, according to the Indiana Department of Environmental Management. 

Having strong EV charging infrastructure in Indiana could be a boon nationwide, given the state’s centralized location in the U.S. 

Indiana has more interstate highways passing through it than any other state, Indiana Governor Eric Holcomb touted in a 2021 report. It’s also home to the nation’s second largest FedEx hub and 41 freight railroads, he added, noting Indiana’s motto of being the “Crossroads of America.”

“Simply put,” Holcomb wrote, “the world moves through Indiana.”

To meet clean energy and net-zero targets by 2030, as set during COP28, the International Energy Agency (IEA) says that rapid expansion of battery storage capacity is necessary.

According to the agency, a rollout of batteries needs to increase six-fold compared to current rates in order to meet global climate goals.

IEA reported that battery costs have decreased by more than 90% over the past 15 years. Last year, battery rollout increased over 130% compared to 2022, and globally, battery capacity increased 42 gigawatts (GW). The increase in battery storage has also contributed to an increase in electric vehicle sales, which have risen from 3 million in 2020 to nearly 14 million in 2023.

“The electricity and transport sectors are two key pillars for bringing down emissions quickly enough to meet the targets agreed at COP28 and keep open the possibility of limiting global warming to 1.5 °C,” IEA Executive Director Fatih Birol said in a statement. “Batteries will provide the foundations in both areas, playing an invaluable role in scaling up renewables and electrifying transport while delivering secure and sustainable energy for businesses and households.”

As The Guardian reported, the global investment in battery storage reached $150 billion in 2023, most of which (about $115 billion) went toward electric vehicle batteries. The biggest investments in EV batteries happened in China, the U.S. and across Europe. Investments in battery storage for electricity grids increased by about five times compared to the previous year as well.

According to the IEA’s Special Report on Batteries and Secure Energy Transitions, battery usage in the energy sector has increased, reaching about 2,400 gigawatt-hours (GWh) in 2023. This is about a fourfold increase over 2020.

While battery costs are falling, demand is increasing and storage capacity is rising, costs need to continue to decline and expansion must increase sixfold by the end of this decade to limit the worst impacts of climate change.

To increase utility-scale battery storage, IEA recommends policy changes to remove restrictions that keep battery storage from accessing energy markets as well as changes to taxing structures, which can sometimes cause double taxation on battery storage projects.

Additionally, the report addresses the need to improve recycling rates to reduce the need to extract raw materials, like lithium and cobalt, for batteries. Recycling improvements and investments in battery innovation will be needed to stabilize the supply chain and help bring costs down.

“The combination of solar PV and batteries is today competitive with new coal plants in India,” Birol said. “And just in the next few years, it will be cheaper than new coal in China and gas-fired power in the United States. Batteries are changing the game before our eyes.”

In the summer of 2022, heavy rainfall damaged a water treatment plant in the city of Jackson, Mississippi, precipitating a high-profile public health crisis. The Republican Governor Tate Reeves declared a state of emergency, as thousands of residents were told to boil their water before drinking it. For some, the pressure in their taps was so low that they couldn’t flush their toilets and were forced to rely on bottled water for weeks. 

Many of the city’s 150,000 residents were wary that their local government could get clean water running through their pipes again. State officials had a history of undermining efforts to repair Jackson’s beleaguered infrastructure, and the city council, for its part, didn’t have the money to make the fixes on its own. So when the federal government stepped in that fall, allocating funding and appointing an engineer to manage the city’s water system, there was reason to believe change may finally be near. 

But as the months wore on, hope turned to frustration. The federally appointed engineer, Ted Henifin, began taking steps to run the city’s water system through a private company, despite Mayor Chokwe Lumumba’s objections. Advocates’ repeated requests for data and other information about Jackson’s drinking water went unanswered, according to a local activist, Makani Themba, and despite Henifin’s assurances before a federal judge that the water was safe to drink, brown liquid still poured out of some taps. Faced with these conditions, a group of advocates sent the Environmental Protection Agency a letter last July asking to be involved in the overhaul of the city’s water system. 

“Jackson residents have weathered many storms, literally and figuratively, over the last several years,” they wrote in the letter. “We have a right and responsibility to be fully engaged in the redevelopment of our water and sewer system.” The letter was followed by an emergency petition to the EPA containing similar requests for transparency and involvement. 

Earlier this month, a federal judge granted the advocates their request, making two community organizations, the Mississippi Poor People’s Campaign and the People’s Advocacy Group, parties to an EPA lawsuit against the city of Jackson for violating the Safe Drinking Water Act. A seat at the table of the legal proceedings, the advocates hope, will allow the city’s residents to have a say in rebuilding their infrastructure and also ward off privatization. The saga in Jackson reflects a wider problem affecting public utilities across the country, with cash-strapped local governments turning to corporations to make badly needed repairs to water treatment plants, distribution pipes, and storage systems, a course that often limits transparency and boxes locals out of the decision-making. 

“This isn’t a uniquely Jackson problem,” said Brooke Floyd, co-director of the Jackson People’s Assembly at the People’s Advocacy Institute. “We need ways for all these cities that need infrastructure repairs to get clean water to their communities.”

The roots of Jackson’s water crisis lie in decades of disinvestment and neglect. Like many other midsize cities around the country, such as Pittsburgh and St. Louis, Jackson declined after white, middle-class residents relocated to the suburbs, taking tax dollars away from infrastructure in increasing need of repair. Between 1980 and 2020, Jackson’s population dropped by around 25 percent. Today, the city is more than 80 percent Black, up from 50 percent in the 1980s. A quarter of Jackson’s residents live below the poverty line, with most households earning less than $40,000 a year, compared with $49,000 for the state overall.

Over the decades, antagonism between the Republican state government and the Democratic and Black-led local government created additional obstacles to updating Jackson’s water and sewage infrastructure. A Title VI civil rights complaint that the NAACP filed with the EPA in September 2022 accused Governor Reeves and the state legislature of “systematically depriving Jackson the funds that it needs to operate and maintain its water facilities in a safe and reliable manner.” The biggest problem, the NAACP argued, was that the state had rejected the city’s proposal for a 1 percent sales tax to pay for infrastructure updates and by directing funds from the EPA’s Drinking Water State Revolving Loan Fund away from the capital city. 

“Despite Jackson’s status as the most populous city in Mississippi, state agencies awarded federal funds” from the EPA program three times in the past 25 years, the complaint read. “Meanwhile, the state has funneled funds to majority-white areas in Mississippi despite their less acute needs.”

In the absence of adequate resources from the state and local government, Jacksonians have learned to fend for themselves, Floyd told Grist. At the height of the water crisis in 2022, federal dollars helped fund the distribution of bottled water to thousands of residents, but when the money dried up, people organized to secure drinking water for households still reckoning with smelly, off-color fluid running from their taps. When Henifin began posting boil-water notices on a smartphone app that some found hard to use, one resident set up a separate community text service. Floyd said that for some residents, these problems are still ongoing today. 

“There’s this sense of, we have to provide for each other because no one is coming,” Floyd said. “We know that the state is not going to help us.”

Henifin has told a federal judge that he’s made a number of moves to improve Jackson’s water quality. The private company that he set up, JXN Water, has hired contractors to update the main water plant’s corrosion control and conducted testing for lead and bacteria like E. coli. But residents and advocates point out that while the water coming out of the system might be clean, the city hosts more than 150 miles of decrepit pipes that can leach toxic chemicals into the water supply. Advocates want the city to replace them and conduct testing in neighborhoods instead of just near the treatment facility, changes that the city has federal money to make. In December 2022, the federal government allocated $600 million to Jackson for repairs to its water system.

But the worry is that this money will be spent on other things. Henifin is the one who handles the federal funds. By court order, he has the authority to enter into contracts, make payments, and change the rates and fees charged to consumers. 

Themba, the local activist, said that Henifin has not responded to residents’ demands for additional testing and access to monitoring data that already exists. Because JXN Water is a private company, it’s not subject to public disclosure laws requiring this information to be shared with the public. (Henifin did not respond to Grist’s requests for comment.) 

Themba points to Pittsburgh as an example of a place where residents fought privatization of their water system and secured a more democratic public utility. In 2012, faced with a lack of state and federal funding, the city turned over its water system to Veolia, an international waste- and water-management giant based in France. Over the following years, the publicly traded company elected for cost-cutting measures that caused lead to enter the water supply of tens of thousands of residents. A local campaign ensued, and advocates eventually won a commitment from the city government to return the water system to city control and give the  public a voice in the system’s management.

“What we’ve learned from all over the country is that privatization doesn’t work for the community,” Themba said. “We want what works.”

The court order that designated Henifin as Jackson’s water manager in 2022 does not outline what will happen once his four-year contract expires in 2026. Last month, the Mississippi Senate passed a bill that would put Jackson’s water in the hands of the state after Henifin steps down, a move that the manager recently said he supports and that Jackson’s mayor strongly opposes. That bill soon failed in the House without a vote. Now that they are part of the lawsuit, advocates hope they’ll have a chance to influence the outcome, before it’s too late. 

“Jackson residents have felt left out of the equation for so long,” Floyd said. “If we lose this, that’s a big deal.”

Last September, Nicaraguan state security forces arrived at Indigenous Miskitu leader Brooklyn Rivera’s home in Bilwi, on the North Caribbean coast. Pretending to be health workers, officers allegedly handcuffed Rivera and beat him with batons before putting him in the back of an ambulance and driving away. More than six months later, Rivera’s family still doesn’t know where he is, or if he is alive. 

Although Rivera had spent decades fighting for Miskitu autonomy and land rights, Carlos Hendy Thomas, another Miskitu leader, said that the recent targeting began with Rivera’s April 2023 trip to New York for the United Nations Permanent Forum on Indigenous Issues, or UNPFII, the world’s largest gathering of Indigenous leaders and activists, and a place for Indigenous peoples to bring attention to issues their communities face. Hendy Thomas said that before Rivera left for New York, government officials warned him not to speak out against the government. He did so anyway, and when Rivera tried to board a plane to return home, he was told that the Nicaraguan authorities had not approved his reentry. Instead, Rivera flew to Honduras and crossed the border back into Nicaragua to return to Bilwi.

A few days before his arrest, Hendy Thomas told Rivera he should leave the country for his own safety, but Rivera insisted his people needed him. That was the last time the two spoke. This year, Hendy Thomas came to the Permanent Forum to ask the United Nations to pressure Nicaragua for information. “We are hoping that by coming here, at least this would come to light, and the U.N. would intervene to get him out from jail, if he’s still in jail, or if he’s even alive,” Hendy Thomas said. 

Rivera’s situation is reflected in a growing trend of Indigenous leaders facing retaliation for speaking out at UNPFII and other international spaces. With few options for Indigenous peoples to advocate in their own countries, especially where regimes refuse to even recognize their existence, many leaders turn to the international community for help. But even that option is becoming less feasible for many Indigenous peoples.

According to the Office of the United Nations High Commissioner for Human Rights, the number and severity of reprisals against people for engaging with the United Nations system has increased. Just in the past two years, Indigenous leaders attending U.N. meetings have faced attempted kidnapping, harassment, arrest, intimidation, online censorship, travel bans, smearing, and other forms of reprisal. 

Hernan Vales, the chief of the Indigenous Peoples and Minorities Section at the Office of the United Nations High Commissioner for Human Rights, said that his office has seen an increase in reported cases of reprisals, but declined to give specific numbers. Vales and other U.N. experts also believe that there may be many more cases that go unreported. A 2023 U.N. report on the issue also says that more people are simply choosing not to engage with the U.N. because they are afraid of repercussions. According to the report, for example, 38 Indigenous Yukpa people decided not to meet with U.N. officials in Venezuela after being stopped by military forces while on their way to the gathering. 

“We cannot tolerate those who bring critical perspective to the United Nations being silenced,” Vales said in a statement. “We need to do more.”

But even with the increased attention and resources available, UNPFII forum members, U.N. experts, and Indigenous leaders say that the problem is still getting worse. Roberto Borrero, who is president of the United Confederation of Taíno Peoples, has attended every session of the Permanent Forum since it began in 2002 and said that the frequency and severity of reprisals has increased, and that the U.N. needs to do more. 

“It really speaks to the credibility of the U.N. to highlight and follow up on this issue,” he said. “If they don’t, the U.N. is going to be even more increasingly seen as ineffective.”

Last year, Edward Porokwa, an Indigenous Maasai leader from Tanzania, attended UNPFII to call attention to human rights violations carried out against Maasai communities, including forced evictions, land-grabbing, and resource deprivation. At the forum, said Porokwa, Tanzanian officials followed him, took videos and pictures without his permission, and said that he was not a legitimate representative. Porokwa said that throughout the forum, he also received anonymous phone calls saying that what he was doing was not right and the government was watching him. 

In Tanzania, Maasai activists have faced arrest and persecution, and Porokwa, spooked by the warnings, decided not to return home for nearly six months. “It was very terrible,” he said. “I could not meet my family. I could not communicate with everybody, because they made me really feel like my life was in danger.” Despite the incident, Porokwa returned to UNPFII this year with an even larger delegation of Maasai leaders. 

Indigenous leaders believe that governments are targeting their U.N. participation because it embarrasses them on the world stage. Exposing human rights abuses to the international community can also have financial impacts. Just this week, the World Bank announced that it is suspending $50 million in funding for a tourism project in Tanzania that has faced allegations of killings, forced evictions, and rape. 

In a statement delivered at UNPFII, Hamisi Malebo, the executive secretary of the United Republic of Tanzania’s National Commission for UNESCO, denied what he called the “baseless and factually inaccurate” allegations made by Maasai leaders. “Tanzania is guided by the rule of law and respect for human rights,” Malebo said. “The government does not condone acts of threat, intimidation, and harassment of its citizens, human rights defenders, and other nonstate actors pursuing this common objective.”

Brian Keane, director of Land Is Life, a nonprofit that advocates for Indigenous rights, says that although threats at the U.N. tend to be less overt than cases like Rivera’s, intimidation and harassment should be taken just as seriously, especially knowing that they can lead to more serious repercussions back home. “It’s a big issue,” he said. “There’s this kind of constant bullying that goes on trying to silence people that are here to speak up for their rights,” he said. 

On the second day of the two-week UNPFII session, Hindou Oumarou Ibrahim, Indigenous Mbororo from Chad and the chair of the forum, delivered a statement condemning any reprisals. 

Last year, a young Indigenous woman from Asia whose name Grist is withholding to protect her identity, was on her way to her local airport to attend UNPFII, when her car was surrounded by a convoy of government vehicles. Officials attempted to drag her out of her car, and it was only after bystanders rushed to her defense that she was eventually permitted to leave. She said she is more careful now. But even after the experience, she returned to UNPFII this year. “I have to continue my work,” she said. “I see my meaning of life that way.”

In July 2022, Yana Tannagasheva, an Indigenous Shor activist from Kemerovo Oblast, Russia, attended a U.N. meeting in Geneva to speak about the harms of coal mining in her community. After she spoke, Tannagasheva and other witnesses say a Russian representative aggressively approached her and demanded to know her name and personal contact information. Tannagasheva, who has lived in exile in Sweden for six years, says the experience shattered her sense of security. “It was so awful. I wanted to cry,” she said. “I was surprised it can happen during a U.N. session.”

Representatives from the Bolivarian Republic of Venezuela, the Republic of Nicaragua, the Russian Federation, and the United Republic of Tanzania did not respond to requests for comment.

Binota Moy Dhamai, Tripura from the Chittagong Hill Tracts in Bangladesh and the chair of the Expert Mechanism on the Rights of Indigenous Peoples, said that reprisals threaten the entire international system and its goals. “If it continues like this then what is the meaning of talking about the sustainable development goals? What is the meaning of talking about peace-building?” he said.

Despite the risks, Carlos Hendy Thomas, from Nicaragua, has no plans to give up his fight. In 2020, Hendy Thomas’ son, who would have inherited his title of hereditary chief, was murdered. The murder, which Hendy Thomas believes was orchestrated by the state because of his son’s defense of Miskitu land rights, was never investigated. Hendy Thomas, who lives in the United States, says he is not that worried about his own safety, even though he is concerned about his family back home. 

“I don’t really care about me,” he said. “They already killed my son. I’m afraid, but I’m speaking. If I don’t, who will?”

In Washington, a dozen dams dot the Columbia River — that mighty waterway carved through the state by a sequence of prehistoric superfloods. Between those dams and the hundreds of others that plug the rivers and tributaries that lace the region, including California and Nevada, the Western United States accounts for most of the hydroelectric energy the country generates from the waters flowing across its landscape. Washington alone captures more than a quarter of that; combined with Oregon and Idaho, the Pacific Northwest lays claim to well over two-fifths of America’s dam-derived electricity. So when a drought hits the region, the nation takes notice.

That happened in 2023 when, according to a recent report, U.S. hydroelectric power hit its lowest level in 22 years. While the atmospheric rivers that poured across California provided the state with abundant energy, the Pacific Northwest endured low summer flows after a late-spring heat wave caused snowpack to melt and river levels to peak earlier than normal. Though dam turbines kept spinning throughout the year — proving that even during a drought the nation’s hydro system remains reliable — last year offered energy providers in the West a glimpse of the conditions they may need to adapt to as the world warms and seasonal weather patterns shift.

While models predict climate change will plunge California and the Southwest deeper into drought, what awaits Washington and Oregon is less clear. The Pacific Northwest will get warmer. That much is certain. But in terms of the rain that places like Seattle and Portland are known for, things get fuzzier.

“Whenever you bring in water precipitation and you’re looking at climate model results, they go in all directions,” said Sean Turner, a water resources and hydropower engineer with Oak Ridge National Laboratory. The Evergreen and Beaver states could get drier or wetter — or both, depending on the time of year.

Nathalie Voisin, chief scientist for water-energy dynamics at the Pacific Northwest National Laboratory, said much of the latest research suggests an increase in total annual hydroelectric power in the region, but, as Turner noted as well, uncertainties remain. “So as a trend, we see an increase” in annual precipitation, Voisin said, “but we also see an increase in variability of very wet years and very dry years.”

Even during wet years, however, the water won’t fall in a gentle mist evenly distributed from new year to year end. The bulk of it, Voisin said, is expected to come from atmospheric rivers streaming overhead between fall and spring, with rivers running low in late summer as the snow and ice in the mountains that rim the region melt ever earlier and no longer keep the waters as high as they historically have.

These are things that the Bonneville Power Administration — the federal agency responsible for selling energy from the 31 federally owned dams along the Columbia and its tributaries to utilities throughout the region — has a keen eye on. In a fact sheet detailing the agency’s plans to ensure its hydropower resources remain resilient, the administration wrote, “By the 2030s, higher average fall and winter flows, earlier peak spring runoff, and longer periods of low summer flows are very likely.” Those times of lower hydroelectric generation will coincide with periods when rising temps are expected to drive people to demand more from their thermostats to keep comfortable.

Given this, if Western states like California, Washington, and Oregon are to meet the 2045 goals for 100 percent clean energy they’ve set, their utilities are going to have to get creative. As it is, when hydropower fails to meet demand, methane, also known as natural gas, tends to fill the gap — even if power companies can’t say for sure that that’s their backstop.

Seattle City Light, for instance, which provides electricity to over 900,000 people across much of the Seattle area, reportedly has been carbon neutral since 2005 thanks in large part to an energy mix that is nearly 90 percent hydropower — around half of which is supplied by Bonneville Power. But with its standard fleet of hydroelectric plants generating below average, Siobhan Doherty, the utility’s director of power management, said it has had to procure new sources of energy to ensure it can comfortably meet customers’ needs. A fair portion of that power comes from other dams in the area, but some of it is also provided by what Doherty called “unspecified” sources purchased from other providers.

Across the West, when utilities like Seattle City Light purchase energy to cover hydropower shortfalls, most of it comes from gas-powered peaker plants, according to Minghao Qiu, an environmental scientist at Stanford University. As a result, emissions rise. Over the 20-year period examined in a study of how droughts impact grid emissions, Qiu and his colleagues found that temporary prolonged hydropower declines led to 121 million tons of carbon emissions. Qiu also found that the plants belching all that pollution often lay far from where the energy is needed.

While the seemingly obvious solution to this challenge is to rapidly deploy wind and solar, Qiu found that this didn’t actually solve the problem.

“So what really happened there is an implicit market that whoever can generate the electricity with the lowest costs are going to generate first,” Qiu said. This means that solar and wind will send all the energy they can because they’re by far the cheapest; hydropower then provides what it can, followed by fossil fuels like methane to plug any holes. “So when hydropower sort of declines,” Qiu said, “the wind power and solar power is already maxed out,” typically leaving gas plants as the remaining option.

Nonetheless, in a bid to keep its grid carbon-free in the long term, Seattle City Light recently signed agreements to buy energy from two independent solar projects, each with at least 40 megawatts of capacity, and is negotiating other, similar arrangements. The fact Bonneville Power has seen a sharp rise in requests from renewable energy developers to connect to its transmission lines suggests other utilities in the region are exploring similar deals.

While those solar farms, in a sense, address the demands that hydro alone can’t meet, the West’s dams help make utility-scale renewables work. Regardless of the inevitable expansion and improvement of turbine and photovoltaic technology, wind and solar will always be intermittent and weather-dependent. In those moments when the gusts stop blowing and the sun stops shining, something has to top off the grid. “Hydro does that better than anything,” Turner said.

Many of the dams administered by Bonneville Power are already equipped to spin up or down as demand dictates, and their ability to meet these moments was perhaps no more apparent than during the lethal heat dome that gripped the Pacific Northwest for one blistering week in June 2021. As streets cracked and power lines melted, the region’s homebound populations drove electricity demand to record levels. To keep the grid going, Bonneville Power relied on the controversial dams along the lower Snake River. The agency released a statement a month after the heat wave, revealing how critical the four lower Snake River dams were during that disaster. At times, they provided well over 1,000 megawatts of power, which is roughly the average draw in Seattle. And while there are credible reasons to remove the dams, Bonneville Power said that without those resources it likely would have had to resort to rolling blackouts to ensure the system wasn’t pushed past its limits.

That experience, and the many more like it that are sure to come, suggest that even as year-to-year dips impact the nation’s dams, the power they provide will long remain a critical component of a carbon-free future.

A new study on plastic pollution in 84 countries has linked half of branded plastic pollution to only 56 firms, with about 24% of the branded plastic waste analyzed connected to only five companies, including The Coca-Cola Company, PepsiCo, Nestlé, Danone and Altria.

A team of researchers analyzed plastic pollution data from the Break Free From Plastic Brand Audit. The data spanned a total of 1,576 brand audit events over five years, from 2018 to 2022.

The analysis revealed about 52% of the 1,873,634 plastic items in the study were unbranded, which could be because sunlight, water or other environmental factors caused fading on labels.

“We found over 50% of plastic items were unbranded, highlighting the need for better transparency about production and labeling of plastic products and packaging to enhance traceability and accountability,” the authors wrote in the study, which was published in the journal Science Advances. “We suggest creation of an international, open-access database into which companies are obliged to quantitatively track and report their products, packaging, brands, and releases to the environment. Additionally, we recommend development of international standards around the branding of packaging to facilitate their identification.” 

Of the remaining plastic items that did have visible branding, the study revealed the highest amount could be linked to one firm, The Coca-Cola Company, with 11% of the plastic waste items. The other brands linked to the highest number of analyzed plastic pieces include PepsiCo (5%), Nestlé (3%), Danone (3%) and Altria (2%). In total, these five brands made up about 24% of the branded plastic waste items.

In total, 56 companies were responsible for over 50% of the branded plastic items, while all of the branded plastic items were linked to 19,586 companies.

Much of the plastic waste could be traced back to companies that produce food, beverage or tobacco products, according to the study.

In addition to analyzing the plastic waste and tracing it back to brands via the Break Free From Plastic Brand Audit data, the study authors also used data from the Ellen MacArthur Foundation to look into plastic production rates by companies.

In comparing the two datasets, the researchers found that a 1% increase in production was followed by about a 1% increase in branded plastic waste.

“The industry likes to put the responsibility on the individual,” Marcus Eriksen, study author and plastic pollution expert at The 5 Gyres Institute, told The Guardian. “But we’d like to point out that it’s the brands, it’s their choice for the kinds of packaging [they use] and for embracing this throwaway model of delivering their goods. That’s what’s causing the greatest abundance of trash.”

Some of the study’s researchers are participating in the ongoing UN Treaty for Plastic Pollution talks this week, and they told The Guardian that the study findings highlight the importance of such a treaty in reducing plastic pollution at the source: plastic producers.
