Agriculture accounts for about 90% of total water consumption in the western United States and around 80% in the rest of the country.

This year, droughts, ferocious wildfires, and extreme heat waves are turning farmlands dusty and ranchlands into grass stubble too short to feed livestock. Without adequate water supplies, farmers and ranchers are suffering, facing unprecedented restrictions on water supplies they have relied on for decades.

But even without historic droughts, growing demand for clean water will create shortages — and soon. Water managers in 40 U.S. states expect some portion of their community to experience shortfalls by 2024. But there is a solution waiting in runoff drains, farmlands, and even the ocean.

As water insecurity grows and populations continue to increase, the country could tap unconventional sources, like salt water and wastewater, for agriculture (including irrigation and animal management), thermoelectric cooling, mining, oil and gas extraction, industrial and manufacturing processes, care for city parks and cemeteries, and even drinking water.

Still, technological, economic, social, and cultural barriers staunch the flow of a circular water economy — where water can be recycled again and again. That is why the National Alliance for Water Innovation (NAWI) just published a master roadmap to help guide future national (and international) technology investments that will not only help keep crops watered and livestock well-fed but also make sure no one goes thirsty when devastating droughts sap our water supplies.

The U.S. Department of Energy formed NAWI in 2019 to accelerate the development of energy-efficient desalination technologies, which extract salts and other impurities from both salt water and wastewater. Their goal is for such devices to produce clean water with the same (or higher) quality as current water treatment methods for 90% of nontraditional resources within the next 10 years. Led by Lawrence Berkeley National Laboratory in Berkeley, California, the NAWI collaboration includes the National Renewable Energy Laboratory (NREL), Oak Ridge National Laboratory, the National Energy Technology Laboratory, and more than 250 industry and academic partners.

Waste not. Growing demand for clean water will create shortages—and soon. Now, the National Alliance for Water Innovation’s new Master Technology Roadmap can guide industries to invest in the most promising technologies, so we can recycle salt water, wastewater, and other waste products again and again.

The master roadmap synthesizes the results of the 2020 NAWI Roadmapping initiative, which focused on technical challenges across five sectors: power, resource extraction (mining and oil and gas exploration and production), industrial, municipal, and agriculture. Though NAWI previously published individual roadmaps tailored to each industry, the master roadmap compiles research opportunities that span more than one industry and could speed the transition to a circular water economy.

“Sector-specific roadmaps gave us almost 90 different things we could focus on,” said Jordan Macknick, NREL’s lead energy-water-land analyst and NAWI’s topic-area lead for data, modeling, and analysis. “There’s no amount of money in the world that can address all those in one project in one coherent way.”

The master roadmap distills those 90 options into a smaller list of those with the greatest impact potential. One of those areas is cost.

Desalination devices that filter contaminants out of salt water or wastewater are not cheap. “We’re currently using these very big bulk separation technologies, like reverse osmosis, which use a lot of energy and are also very expensive, to remove trace contaminants,” Macknick said. “It’s almost like you’re using a sledgehammer to put a tack in a bulletin board.”

He and the broader NAWI team are researching ways to extract contaminants faster, cheaper, and smarter. For example, bulk separation technologies are not necessary to extract microscopic contaminants, like selenium or boron. Smaller, more precise technologies could perform the same job for less money and energy input.

Their goal is something called pipe parity. In Denver, Colorado, for example, if traditional water sources run out, what happens then? The city could pump water over the mountains, but that method gets expensive fast. If the NAWI team can design technology that makes recycled water the cheapest back-up option, that is a win.

But cost is not the only barrier.

“The traditionally conservative water industry is understandably risk averse,” Macknick said. “In general, that’s a good thing for our health. But it also makes the pace of innovation more challenging.” To incentivize the water industry to incorporate nontraditional water sources into their current infrastructure, Macknick and the cross-institutional team need to bring the costs down but also ensure the science is “bulletproof,” Macknick said.

And the water industry is not the only group that needs some convincing. Some consumers still balk at the idea of drinking recycled water.

“There’s a major perception issue when we talk about recycling or reusing water that, somehow, it’s not clean enough or as pure as the water we might get from a river and treat, when in fact, we’re oftentimes treating it to a higher standard than the water that we might pull directly from a river,” Macknick said.

Changing perceptions might take time, but, in the meantime, NREL can help speed the development of more efficient, cost-effective technologies that edge recycled water closer to widespread use. No single technologic breakthrough will get the job done; water treatment often uses a dozen different processes strung together. But with NREL’s deep knowledge of systems analysis, the laboratory’s researchers can analyze these processes as a whole and determine which changes might have the biggest impact.

NREL also previously led the development of an analytical tool called the Water Technoeconomic Assessment Pipe-Parity Platform (Water-TAP3), which evaluates water technology costs, energy use, environmental impacts, and resiliency trade-offs. NREL researchers also developed a data repository called the Water Data Analysis and Management System (Water DAMS), a national go-to for water technology and treatment data. And the laboratory does not just collect and analyze data. NREL’s advanced manufacturing researchers can help design entirely new materials to extract contaminants with greater speed and reduced cost.

NAWI’s new master roadmap will help guide future research at NREL and beyond. “The master roadmap is what is guiding our future investments,” Macknick said. “As the field advances, not only in the United States and with NAWI but also internationally, we want it to be a living document that changes as the sector advances and adapts.”

New technology, developed with guidance from the NAWI master roadmap, could allow farmers to reuse wastewater and even some of its extracted contaminants — phosphorous and nitrogen — as fertilizer. As climate change incites more droughts, wildfires, and extreme heat waves, farmers and ranchers could stay afloat with unconventional water sources.

Despite its name, wastewater need not be wasted.

Volkswagen’s 47% BEV sales jump includes a 24% boost in the US

Volkswagen Group‘s global EV deliveries surged by about 50% in the first half of 2025 year-over-year, with 465,500 battery electric vehicles (BEVs) delivered globally by the end of June.

That’s a 47% jump in BEV deliveries from 317,200 in the first half of 2024. BEVs made up 11% of Volkswagen Group’s total global sales, up from just 7% a year ago.

Europe saw the biggest growth in BEVs in H1 2025, where deliveries nearly doubled, up 89%. The US saw solid gains too, with a 24% increase. China was the outlier, with BEV sales slipping 34%, thanks to stiff competition from domestic brands. Even so, Volkswagen Group remains the BEV market leader in Europe, holding onto a 28% share. “One in five vehicles we delivered in Western Europe is now purely electric,” noted Volkswagen Group’s Marco Schubert.

Plug-in hybrids saw a solid boost, too. Volkswagen Group delivered 192,300 PHEVs worldwide in the first half of the year – a 41% jump from the 136,800 sold during the same period in 2024. The latest wave of second-gen PHEVs, with all-electric ranges of up to 143 km (about 89 miles), is helping drive that demand.

VW Group reports that its best-selling BEVs globally are:

  • Volkswagen ID.4/ID.5 84,900
  • Volkswagen ID.3 60,700
  • Audi Q4 e-tron (incl. Sportback) 44,600
  • Volkswagen ID.7 (incl. Tourer) 38,700
  • Škoda Enyaq (incl. Coupé) 38,700
  • Audi Q6 e-tron (incl. Sportback) 36,500

The new Nissan LEAF EV is already facing production cuts, but that’s not the whole story

The new Nissan LEAF EV is already facing production cuts, but that's not the whole story

Nissan is already pulling back production plans for the new LEAF, which is set to launch later this year. As it scrambles to turn things around, this could further complicate Nissan’s recovery plan. And there’s even more going on behind the scenes.

Nissan scales back new LEAF EV production plans

The new LEAF is expected to be one of the most significant factors in Nissan’s comeback. In May, Nissan announced plans to reduce its global workforce by around 15% and close seven plants as part of its restructuring.

Last week, it began talks with workers at its Sunderland, UK, plant, where the new LEAF will be built, over voluntary retirement.

According to a new report from Japan’s Kyodo News (via Reuters), Nissan is already cutting production plans for the next-gen LEAF ahead of its launch later this year. The report cites a shortage of rare earth minerals due to China’s new export restrictions.

No specific details were mentioned, but a separate Automotive News report claims Nissan is also delaying two EVs that were scheduled to be built at its Canton, Mississippi, plant.

An internal memo revealed it would delay production by around 10 months. Nissan cited “recent slowing EV demand in the US,” thanks to the Trump Administration eliminating the federal tax credit.

It will now begin production of the Nissan-branded model in November 2028 and the Infiniti-branded version in March 2029.

Nissan spokesperson Kyle Bazemore said, “We’ve made the strategic decision to slightly adjust the production timeline for our EVs at the Canton plant.” It looks like Nissan is adjusting more than just that.

Adding to that, Nissan suspended production of three vehicles made in the US, according to a report from Nikkei on Wednesday. Nissan halted production of the Pathfinder and Murano at its Tennessee plant in May, as well as the Frontier pickup, which is built in Mississippi.

Electrek’s Take

As part of its recovery plan, Re:Nissan aims to cut costs by 250 billion yen as it seeks to return to profitability by the end of fiscal year 2026.

However, if it continues to delay production, Nissan will only fall further behind. The Japanese automaker is already losing market share to EV giants like BYD due to its aging vehicle lineup.

The new LEAF is expected to be a key growth driver over the next few years, with significant improvements in range, style, and charging capabilities. Facing a shortage, how many LEAFs will Nissan be able to build?

Nissan is the latest automaker to adjust its EV plans following Trump’s “Big, Beautiful Bill.” Honda recently canceled plans to launch its three-row electric SUV in the US.
