Batteries are so cheap now, solar power doesn’t sleep
A new report from global energy think tank Ember says batteries have officially hit the price point that lets solar power deliver affordable electricity almost every hour of the year in the sunniest parts of the world.
The study looked at hourly solar data from 12 cities and found that in sun-soaked places like Las Vegas, you could pair 6 gigawatts (GW) of solar panels with 17 gigawatt-hours (GWh) of batteries and get a steady 1 GW of power nearly 24/7. The cost? Just $104 per megawatt-hour (MWh) based on average global prices for solar and batteries in 2024. That’s a 22% drop in a year and cheaper than new coal ($118/MWh) and nuclear ($182/MWh) in many regions.
Ember calls it “24/365 solar generation,” and it’s not just a theoretical model. Cities like Muscat, Oman, and Las Vegas can hit that steady power mark for up to 99% of the hours in a year. Hyderabad, Madrid, and Buenos Aires can reach 80–95% of the way there using that same solar-plus-storage setup with some cloud cover. And even cloudier cities like Birmingham in the UK can cover about 62% of hours annually.
“This is a turning point in the clean energy transition,” said Kostantsa Rangelova, global electricity analyst at Ember. “Around-the-clock solar is no longer a distant dream; it’s an economic reality of the world. It unlocks game-changing opportunities for energy-hungry industries like data centres and manufacturing.”
This is an enormous opportunity for sunny regions in Africa and Latin America. Manufacturers and data centers could also tap into solar-plus-storage and skip long waits (and big bills) for new grid connections.
It’s not a silver bullet for grid-wide reliability, but it lets solar carry much more of the load, especially where sunshine is abundant. Batteries also help avoid costly grid expansions by allowing up to five times more solar to plug into existing connections.
In 2024 alone, global battery prices dropped 40%, which helped drive down solar-plus-storage costs by 22%. Record-low tenders from countries like Saudi Arabia point to even cheaper options coming soon.
Real-world projects are already online: The UAE built the world’s first gigawatt-scale 24-hour solar facility. Arizona is already home to solar-powered data centers. And as battery tech keeps improving, round-the-clock solar could become the backbone of clean energy systems in the world’s sunniest places.

Electricity prices are rising quickly for U.S. households, even as overall inflation has cooled.
Electricity prices rose 4.5% in the past year, according to the consumer price index for May 2025 — nearly double the inflation rate for all goods and services.
The U.S. Energy Information Administration estimated in May that retail electricity prices would outpace inflation through 2026. Prices have already risen faster than the broad inflation rate since 2022, it said.
“It’s a pretty simple story: It’s a story of supply and demand,” said David Hill, executive vice president of energy at the Bipartisan Policy Center and former general counsel at the U.S. Energy Department.
There are many contributing factors, economists and energy experts said.
At a high level, the growth in electricity demand and deactivation of power-generating facilities are outstripping the pace at which new electricity generation is being added to the electric grid, Hill said.
Prices are regional
U.S. consumers spent an average of about $1,760 on electricity in 2023, according to the EIA, which cited federal data from the Bureau of Labor Statistics.
Of course, cost can vary widely based on where consumers live and their electricity consumption. The average U.S. household paid about 17 cents per kilowatt-hour of electricity in March 2025 — but ranged from a low of about 11 cents per kWh in North Dakota to about 41 cents per kWh in Hawaii, according to EIA data.
Households in certain geographies will see their electric bills rise faster than those in others, experts said.
Residential electricity prices in the Pacific, Middle Atlantic and New England regions — areas where consumers already pay much more per kilowatt-hour for electricity — could increase more than the national average, according to the EIA.
“Electricity prices are regionally determined, not globally determined like oil prices,” said Joe Seydl, a senior markets economist at J.P. Morgan Private Bank.
The EIA expects average retail electricity prices to increase 13% from 2022 through 2025.
That means the average household’s annual electricity bill could rise about $219 in 2025 relative to 2022, to about $1,902 from $1,683, according to a CNBC analysis of federal data. That assumes their usage is unchanged.
But prices for Pacific area households will rise 26% over that period, to more than 21 cents per kilowatt-hour, EIA estimates. Meanwhile, households in the West North Central region will see prices increase 8% in that period, to almost 11 cents per kWh.
However, certain electricity trends are happening nationwide, not just regionally, experts said.
Data centers are ‘energy hungry’

Electricity demand growth was “minimal” in recent decades due to increases in energy efficiency, according to Jennifer Curran, senior vice president of planning and operations at Midcontinent Independent System Operator, who testified at a House energy hearing in March. (MISO, a regional electric-grid operator, serves 45 million people across 15 states.)
Meanwhile, U.S. “electrification” swelled via use of electronic devices, smart-home products and electric vehicles, Curran said.
Now, demand is poised to surge in coming years, and data centers are a major contributor, experts said.
Data centers are vast warehouses of computer servers and other IT equipment that power cloud computing, artificial intelligence and other tech applications.

Data center electricity use tripled to 176 Terawatt-hours in the decade through 2023, according to the U.S. Energy Department. Use is projected to double or triple by 2028, the agency said.
Data centers are expected to consume up to 12% of total U.S. electricity by 2028, up from 4.4% in 2023, the Energy Department said.
They’re “energy hungry,” Curran said. Demand growth has been “unexpected” and largely due to support for artificial intelligence, she said.
The U.S. economy is set to consume more electricity in 2030 for processing data than for manufacturing all energy-intensive goods combined, including aluminum, steel, cement and chemicals, according to the International Energy Agency.
Continued electrification among businesses and households is expected to raise electricity demand, too, experts said.
The U.S. has moved away from fossil fuels like coal, oil and natural gas to reduce planet-warming greenhouse-gas emissions.
For example, more households may use electric vehicles rather than gasoline-powered cars or electric heat pumps versus a gas furnace — which are more efficient technologies but raise overall demand on the electric grid, experts said.
Population growth and cryptocurrency mining, another power-intensive activity, are also contributors, said BPC’s Hill.
‘All about infrastructure’

As electricity demand is rising, the U.S. is also having problems relative to transmission and distribution of power, said Seydl of J.P. Morgan.
Rising electricity prices are “all about infrastructure at this point,” he said. “The grid is aged.”
For example, transmission line growth is “stuck in a rut” and “way below” Energy Department targets for 2030 and 2035, Michael Cembalest, chairman of market and investment Strategy for J.P. Morgan Asset & Wealth Management, wrote in a March energy report.
Shortages of transformer equipment — which step voltages up and down across the U.S. grid — pose another obstacle, Cembalest wrote. Delivery times are about two to three years, up from about four to six weeks in 2019, he wrote.
“Half of all US transformers are near the end of their useful lives and will need replacing, along with replacements in areas affected by hurricanes, floods and wildfires,” Cembalest wrote.
Transformers and other transmission equipment have experienced the second highest inflation rate among all wholesale goods in the US since 2018, he wrote.
Meanwhile, certain facilities like old fossil-fuel powered plants have been decommissioned and new energy capacity to replace it has been relatively slow to come online, said BPC’s Hill. There has also been inflation in prices for equipment and labor, so it costs more to build facilities, he said.
In a high-tech move that we can all get behind and isn’t dystopian at all, the City of Barcelona is feeding camera data from its city buses into an advanced AI, but they swear they’re not using the footage to to issue tickets to bad drivers. Yet.
Barcelona and its Ring Roads Low Emission Zone have earned lots of fans by limiting ICE traffic in the city’s core. The city’s latest idea to promote mass transit is the deployment of an artificial intelligence system developed by Hayden AI for automatic enforcement of reserved lanes and stops to improve bus circulation – but while it seems to be working as intended, it’s raising entirely different questions.
“Bus lanes are designed to help deliver reliable, fast, and convenient public transport service. But private vehicles illegally using bus lanes make this impossible,” explains Laia Bonet, First Deputy Mayor, Area for Urban Planning, Ecological Transition, Urban Services and Housing at the Ajuntament de Barcelona. “We are excited to partner with Hayden AI to learn where these problems occur and how they are impacting our public transport service.”
Currently operating as a pilot program on the city’s H12 and D20 bus lines, the system uses cameras installed on the city’s electric buses to detect vehicles that commit static violations in the bus lanes and stops (read: stopping or parking where you shouldn’t). The Hayden AI system then analyses that data and provides statistical information on what it captures while the bus is driving along on its daily route.
Hayden AI says that, while it photographs and records video sequences and collects contextual information of the violation, its cameras do not record license plates or people and no penalties are being issued to drivers or owners of the vehicles.
So far so good, right? But it’s what happens once the six mont pilot is over that seems like it should be setting off alarm bells.
Big Brother Bus is watching
The footage is manually reviewed by a Transports Metropolitans de Barcelona (TMB) officer, who reportedly reviewed some 2,500 violations identified by AI in May alone. But, while the system isn’t being used to issue violations during the pilot program, it easily could.
And, in fact, it already has … and the AI f@#ked up royally.
AI writes thousands of bad tickets
When AI was given the ability to issue citations in New York City earlier this year, it wrote more than 290,000 tickets (that’s right: two-hundred and ninety thousand) in just three months, generating nearly $21 million in revenue for the city. The was just one problem: thousands of those drivers weren’t doing anything wrong.
What’s more, the photos generated by the AI powered cameras were supposed to be approved only after being verified by a human, but either that didn’t happen, or it did happen and the human operator in question wasn’t paying attention, or (maybe the worst possibility) the violations were mistakes or hallucinations, and the human checker couldn’t tell the difference.
In OpenAI’s tests of its newest o3 and o4-mini reasoning models, the company found the o3 model hallucinated 33% of the time during its PersonQA tests, in which the bot is asked questions about public figures. When asked short fact-based questions in the company’s SimpleQA tests, OpenAI said o3 hallucinated 51% of the time. The o4-mini model fared even worse: It hallucinated 41% of the time during the PersonQA test and 79% of the time in the SimpleQA test, though OpenAI said its worse performance was expected as it is a smaller model designed to be faster. OpenAI’s latest update to ChatGPT, GPT-4.5, hallucinates less than its o3 and o4-mini models. The company said when GPT-4.5 was released in February the model has a hallucination rate of 37.1% for its SimpleQA test.
I don’t know about you guys, but if we had a local traffic cop that got it wrong 33% of the time (at best), I’d be surprised if they kept their job for very long. But AI? AI has a multibillion dollar hype train and armies of undereducated believers talking about singularities and building themselves blonde robots with boobs. And once the AI starts issuing tickets to the AI that’s driving your robotaxi, it can just call its buddy AI the bank to send over your money. No human necessary, at any point, and the economy keeps on humming.
But, like – I’m sure that’s fine. Embrace the future and all that … right?

The Honda Prologue continues to surprise, ranking among the top ten most leased vehicles (gas-powered or EV) in the US in the first quarter. It was the only EV, outside of Tesla’s Model Y and Model 3, that made the list.
Honda Prologue EV ranks among most leased vehicles
After launching the Prologue in the US last March, Honda’s electric SUV took off. In the second half of the year, it was the second-best-selling electric SUV, trailing only the Tesla Model Y.
The Prologue remains a top-selling EV in the US this year, with over 13,500 units sold through May. That’s not too bad, considering it only sold 705 through May of last year.
According to a new Experian report (via Automotive News), Honda’s success is being driven by ultra-affordable lease rates. In the first quarter, nearly 60% of new EV buyers in the US chose to lease, up from just 36% a year ago.
Three EVs ranked in the top ten most leased vehicles, including the Tesla Model Y, Model 3, and Honda Prologue.
Tesla’s Model Y and Model 3 took the top two spots, while the Honda Prologue ranked number seven. Those who leased Tesla’s Model 3 paid $402 per month, Honda Prologue lessees paid $486 a month.
Given the average loan rate was $708 a month for those who bought it, it’s no wonder nearly 90% chose to lease. Under 9% chose to buy, while less than 2% paid cash.
The discounts are piling up, but for how long?
To give you a better idea, the average monthly payment for a new vehicle lease in the US in the first quarter was $595.
With over $20,000 in discounts, Honda’s luxury Acura brand is selling a surprising number of EVs in the US. The nearly $65,000 Acura ZDX is sold for under $40,000 on average in May, according to Cox Automotive’s EV Market Monitor report for May.
The trend is primarily thanks to the $7,500 federal EV tax credit, which is being passed on to customers through leasing.
With the Trump administration and Senate Republicans aiming to kill off federal subsidies, the savings could soon disappear. If the Senate’s recently proposed bill is passed, the $7,500 credit would expire within 180 days. It would not only make electric vehicles more expensive, but it would also put the US further behind China and others leading the shift to electrification.
Some automakers, including GM, are expected to continue offering the incentives. “GM has been very competitive on the incentives on their end, and that is not scheduled to end.”
After outselling Ford, GM’s Chevy is now the fastest-growing EV brand in the US through May. Chevy is starting to chip away at Tesla’s lead, largely thanks to the new Equinox EV, or “America’s most affordable +315 range EV,” as GM calls it.
According to Xperian, those who leased a new Chevy Equinox EV in Q1 paid $243 less than those who financed it. The electric Equinox stood out in Cox Automotive’s EV Market Monitor report with an average selling price under $40,000, even without incentives.
The Chevy Equinox EV remains one of the most affordable EVs on the market. Starting at just $34,995, the base LT FWD model offers an EPA-estimated range of 319 miles.
Looking to test out some of the most popular EVs for yourself? With Honda Prologue leases as low as $259 per month and Chevy Equinox EV leases starting at just $289 per month, the deals are hard to pass up right now while the incentives are still here.
