Electricity That Costs Nothing—or Even Less? It’s Happening More and More

A surge in wind and solar power means many businesses and consumers around Europe can get paid for plugging in. The U.S. could be next.

KERKDRIEL, the Netherlands—For much of the spring and summer, Jeroen van Diesen got paid for using electricity.

Sometimes his neighbours came over to power up too, generating even more cash.

Van Diesen’s situation reflects the strange, new dynamics of electricity that could soon become the norm in many parts of the world: A big increase in wind and solar power has pushed wholesale prices to zero or below for many hours of the year, spurring a sea change in the way people use power—based on whether the sun is shining or the wind is blowing.

Most people pay a fixed price for each kilowatt-hour of electricity they consume throughout the day. The price is set by their power company and only changes at infrequent intervals—once a week, a month or even only once a year.

Van Diesen, a software salesman, recently signed up to receive electricity from two providers that charge him the hourly price on the Dutch wholesale power market, rather than a fixed price that resets monthly or annually. When the price of electricity falls low enough, smart meters in his house begin charging his two electric cars.

Wholesale prices swing wildly each hour of the day, and even more so as a larger share of electricity flows from wind and solar installations. Because the generation costs of wind or solar farms are negligible, market prices will be near zero when there is enough renewable power to cover most of a region’s electricity demand.

Electricity market dynamics get weirder when renewable-energy producers don’t have an incentive to stop feeding power into the grid, usually because of government subsidies. Then grids can be flooded with excess power, pushing prices into negative territory.

Van Diesen said he’s made 30 euros, equivalent to around $34, over the past five months charging his car, enough to cover the service fee from his power supplier, a Norwegian company called Tibber.

“I’m charging the car for free,” said van Diesen, who is part of a group of clean-energy enthusiasts in the Netherlands who call themselves green nerds. “To me it’s also like a hobby and a game—how far can I go?”

Doing laundry in the evening? The electricity could be free a few hours later when demand dies down and the wind picks up. Likewise, in regions with lots of solar power, charging an electric vehicle in the morning is usually far more expensive than powering up under the midday sun—or whenever the price is right.

In the U.S., most states don’t currently allow such real-time pricing, but many think that will change. Already, in some of the world’s biggest economies from Western Europe to California, the occurrence of zero and negative wholesale power prices is growing fast.

Negative prices

Wholesale prices across continental Europe have fallen to zero or below in 6% of all hours this year, up sharply from 2.2% in 2023 and just 0.3% in 2022, according to data collected by Entso-E, the group of European transmission system operators. In markets with lots of renewable capacity, this year’s figure was higher: 8% in the Netherlands, 11% in Finland and 12% in Spain. Analysts expect those numbers will grow as more solar panels and wind turbines are installed.

The changes sweeping Europe’s electricity markets, which were accelerated by the energy crisis brought on by the war in Ukraine, show what could happen in the U.S. in a few years when renewable capacity reaches a similar scale. In 2023, 44% of EU electricity was generated by renewables, compared with 21% in the U.S.

In some U.S. markets—sunny California, the wind-swept Great Plains, and Texas—zero and negative prices are already common. The wholesale price in Southern California was negative nearly 20% of all hours this year because of the region’s boom in solar-panel installations. That compares to around 5% last year, according to data collected by the U.S. Energy Information Administration.

U.S. regulators have been cautious about allowing households and companies to sign up for electricity plans that charge them wholesale prices, fearing consumers could be hit with big bills if prices jump. Texas consumers who signed such contracts were walloped with huge bills in 2021 when a rare winter storm sent prices soaring.

States’ reluctance, however, may now be waning as policymakers increasingly see real-time pricing as a way to lower peak demand, reduce the need for costly infrastructure and integrate more renewables into the grid.

California regulators this year ordered the state’s utilities to expand dynamic price pilot programs that have only been available for a select group of customers.

Your overall power bill still won’t be zero in a clean-energy future. Generation costs comprised around 60% of customer bills on average in the U.S. in 2023. Transmission and distribution costs account for most of the rest—and are expected to grow sharply in the coming decade to reinforce the grid for electric heating, electric transport and data centers.

Negative prices could also be reined in over the next few years as governments from Europe to California pare back renewable-energy subsidies. Governments are particularly focused on trimming subsidies for solar power, which is driving negative prices in a number of markets.

Green nerds

In Europe, energy-hungry manufacturers are shifting their operating strategies to maximise energy consumption when prices are close to zero or negative, while throttling back when prices are high.

Linde, a U.K.-based engineering company, is building a new generation of industrial gas plants that can be quickly ramped up and down depending on the wholesale price of power.

When solar and wind power drive prices down, Linde’s plants fire up and send the output to large tanks. When electricity prices shoot up again, the plants can ramp back down and supply customers out of the gases stored in the tanks.

“The tank functions like a virtual battery,” said Klaus Ohlig, a research and development executive at Linde Engineering.

Trimet, an aluminium producer that is one of Germany’s single-largest power consumers, is overhauling its smelters to vary their power consumption depending on the availability of renewable energy on the grid.

A new European Union law requires dynamic-price power contracts be made available to consumers across the 27-nation bloc. Tibber, a power retailer based in Norway that charges its customers the wholesale hourly price, has signed up more than one million households across the Nordic countries, Germany and the Netherlands.

Edgeir Aksnes, Tibber’s co-founder and chief executive, says he doesn’t expect customers to constantly track the hourly price before deciding when to charge their car or run appliances.

“We can automate all of this for you. You don’t have to think about it,” he said.

Some enthusiasts, however, like to get into the weeds.

Wouter van Embden, a 49-year-old Dutch entrepreneur and one of the country’s so-called green nerds, switched to Tibber earlier this year. On a recent summer Sunday, the battery in his home began charging as solar power flooded the Dutch grid and the wholesale power price fell to zero. He also charged his two electric cars and programmed his heat pump to make the water in the house tank extra hot.

Toward the evening, as prices rose with the drop-off in solar, van Embden’s battery—which he and his son built at home—would power his home as well as feed into the Dutch grid.

“I have to be honest, when I started building the battery I had so many outages. There was a lot of testing to do,” he said. “But now it’s working pretty stable.”

Subsidised minivans, no income taxes: Countries have rolled out a range of benefits to encourage bigger families, with no luck

Imagine if having children came with more than $150,000 in cheap loans, a subsidised minivan and a lifetime exemption from income taxes.

Would people have more kids? The answer, it seems, is no.

These are among the benefits—along with cheap child care, extra vacation and free fertility treatments—that have been doled out to parents in different parts of Europe, a region at the forefront of the worldwide baby shortage. Europe’s overall population shrank during the pandemic and is on track to contract by about 40 million by 2050, according to United Nations statistics.

Birthrates have been falling across the developed world since the 1960s. But the decline hit Europe harder and faster than demographers expected—a foreshadowing of the sudden drop in the U.S. fertility rate in recent years.

Reversing the decline in birthrates has become a national priority among governments worldwide, including in China and Russia , where Vladimir Putin declared 2024 “the year of the family.” In the U.S., both Kamala Harris and Donald Trump have pledged to rethink the U.S.’s family policies . Harris wants to offer a $6,000 baby bonus. Trump has floated free in vitro fertilisation and tax deductions for parents.

Europe and other demographically challenged economies in Asia such as South Korea and Singapore have been pushing back against the demographic tide with lavish parental benefits for a generation. Yet falling fertility has persisted among nearly all age groups, incomes and education levels. Those who have many children often say they would have them even without the benefits. Those who don’t say the benefits don’t make enough of a difference.

Two European countries devote more resources to families than almost any other nation: Hungary and Norway. Despite their programs, they have fertility rates of 1.5 and 1.4 children for every woman, respectively—far below the replacement rate of 2.1, the level needed to keep the population steady. The U.S. fertility rate is 1.6.

Demographers suggest the reluctance to have kids is a fundamental cultural shift rather than a purely financial one.

“I used to say to myself, I’m too young. I have to finish my bachelor’s degree. I have to find a partner. Then suddenly I woke up and I was 28 years old, married, with a car and a house and a flexible job and there were no more excuses,” said Norwegian Nancy Lystad Herz. “Even though there are now no practical barriers, I realised that I don’t want children.”

The Hungarian model

Both Hungary and Norway spend more than 3% of GDP on their different approaches to promoting families—more than the amount they spend on their militaries, according to the Organization for Economic Cooperation and Development.

Hungary says in recent years its spending on policies for families has exceeded 5% of GDP. The U.S. spends around 1% of GDP on family support through child tax credits and programs aimed at low-income Americans.

Hungary’s subsidised housing loan program has helped almost 250,000 families buy or upgrade their homes, the government says. Orsolya Kocsis, a 28-year-old working in human resources, knows having kids would help her and her husband buy a larger house in Budapest, but it isn’t enough to change her mind about not wanting children.

“If we were to say we’ll have two kids, we could basically buy a new house tomorrow,” she said. “But morally, I would not feel right having brought a life into this world to buy a house.”

Promoting baby-making, known as pro natalism, is a key plank of Prime Minister Viktor Orbán ’s broader populist agenda . Hungary’s biennial Budapest Demographic Summit has become a meeting ground for prominent conservative politicians and thinkers. Former Fox News anchor Tucker Carlson and JD Vance, Trump’s vice president pick, have lauded Orbán’s family policies.

Orbán portrays having children inside what he has called a “traditional” family model as a national duty, as well as an alternative to immigration for growing the population. The benefits for child-rearing in Hungary are mostly reserved for married, heterosexual, middle-class couples. Couples who divorce lose subsidised interest rates and in some cases have to pay back the support.

Hungary’s population, now less than 10 million, has been shrinking since the 1980s. The country is about the size of Indiana.

“Because there are so few of us, there’s always this fear that we are disappearing,” said Zsuzsanna Szelényi, program director at the CEU Democracy Institute and author of a book on Orbán.

Hungary’s fertility rate collapsed after the fall of the Soviet Union and by 2010 was down to 1.25 children for every woman. Orbán, a father of five, and his Fidesz party swept back into power that year after being ousted in the early 2000s. He expanded the family support system over the next decade.

Hungary’s fertility rate rose to 1.6 children for every woman in 2021. Ivett Szalma, an associate professor at Corvinus University of Budapest, said that like in many other countries, women in Hungary who had delayed having children after the global financial crisis were finally catching up.

Then progress stalled. Hungary’s fertility rate has fallen for the past two years. Around 51,500 babies have been born there this year through August, a 10% drop compared with the same period last year. Many Hungarian women cite underfunded public health and education systems and difficulties balancing work and family as part of their hesitation to have more children.

Anna Nagy, a 35-year-old former lawyer, had her son in January 2021. She received a loan of about $27,300 that she didn’t have to start paying back until he turned 3. Nagy had left her job before getting pregnant but still received government-funded maternity payments, equal to 70% of her former salary, for the first two years and a smaller amount for a third year.

She used to think she wanted two or three kids, but now only wants one. She is frustrated at the implication that demographic challenges are her responsibility to solve. Economists point to increased immigration and a higher retirement age as other offsets to the financial strains on government budgets from a declining population.

“It’s not our duty as Hungarian women to keep the nation alive,” she said.

Big families

Hungary is especially generous to families who have several children, or who give birth at younger ages. Last year, the government announced it would restrict the loan program used by Nagy to women under 30. Families who pledge to have three or more children can get more than $150,000 in subsidised loans. Other benefits include a lifetime exemption from personal taxes for mothers with four or more kids, and up to seven extra annual vacation days for both parents.

Under another program that’s now expired, nearly 30,000 families used a subsidy to buy a minivan, the government said.

Critics of Hungary’s family policies say the money is wasted on people who would have had large families anyway. The government has also been criticised for excluding groups such as the minority Roma population and poorer Hungarians. Bank accounts, credit histories and a steady employment history are required for many of the incentives.

Orbán’s press office didn’t respond to requests for comment. Tünde Fűrész, head of a government-backed demographic research institute, disagreed that the policies are exclusionary and said the loans were used more heavily in economically depressed areas.

Government programs weren’t a determining factor for Eszter Gerencsér, 37, who said she and her husband always wanted a big family. They have four children, ages 3 to 10.

They received about $62,800 in low-interest loans through government programs and $35,500 in grants. They used the money to buy and renovate a house outside of Budapest. After she had her fourth child, the government forgave $11,000 of the debt. Her family receives a monthly payment of about $40 a month for each child.

Most Hungarian women stay home with their children until they turn 2, after which maternity payments are reduced. Publicly run nurseries are free for large families like hers. Gerencsér worked on and off between her pregnancies and returned full-time to work, in a civil-service job, earlier this year.

She still thinks Hungarian society is stacked against mothers and said she struggled to find a job because employers worried she would have to take lots of time off.

The country’s international reputation as family-friendly is “what you call good marketing,” she said.

Nordic largesse

Norway has been incentivising births for decades with generous parental leave and subsidised child care. New parents in Norway can share nearly a year of fully paid leave, or around 14 months at 80% pay. More than three months are reserved for fathers to encourage more equal caregiving. Mothers are entitled to take at least an hour at work to breast-feed or pump.

The government’s goal has never been explicitly to encourage people to have more children, but instead to make it easier for women to balance careers and children, said Trude Lappegard, a professor who researches demography at the University of Oslo. Norway doesn’t restrict benefits for unmarried parents or same-sex couples.

Its fertility rate of 1.4 children per woman has steadily fallen from nearly 2 in 2009. Unlike Hungary, Norway’s population is still growing for now, due mostly to immigration.

“It is difficult to say why the population is having fewer children,” Kjersti Toppe, the Norwegian Minister of Children and Families, said in an email. She said the government has increased monthly payments for parents and has formed a committee to investigate the baby bust and ways to reverse it.

More women in Norway are childless or have only one kid. The percentage of 45-year-old women with three or more children fell to 27.5% last year from 33% in 2010. Women are also waiting longer to have children—the average age at which women had their first child reached 30.3 last year. The global surge in housing costs and a longer timeline for getting established in careers likely plays a role, researchers say. Older first-time mothers can face obstacles: Women 35 and older are at higher risk of infertility and pregnancy complications.

Gina Ekholt, 39, said the government’s policies have helped offset much of the costs of having a child and allowed her to maintain her career as a senior adviser at the nonprofit Save the Children Norway. She had her daughter at age 34 after a round of state-subsidised IVF that cost about $1,600. She wanted to have more children but can’t because of fertility issues.

She receives a monthly stipend of about $160 a month, almost fully offsetting a $190 monthly nursery fee.

“On the economy side, it hasn’t made a bump. What’s been difficult for me is trying to have another kid,” she said. “The notion that we should have more kids, and you’re very selfish if you have only had one…those are the things that took a toll on me.”

Her friend Ewa Sapieżyńska, a 44-year-old Polish-Norwegian writer and social scientist with one son, has helped her see the upside of the one-child lifestyle. “For me, the decision is not about money. It’s about my life,” she said.
