Bill Gross is best known for founding the technology incubator Idealab in 1996, after starting a handful of companies in software, education tech and online services spaces.
In the quarter-century since, Idealab has has started more than 150 companies and had more than 45 successful exits. Today, Gross devotes virtually all of his time to being the CEO of clean energy company Heliogen, which he launched out of Idealab in 2013, scoring Bill Gates as an early investor.
But Gross has always been a climate tech entrepreneur. He’s just had to wait for the world to catch up with him a bit.
He actually started a solar device company when he was in high school, long before he got into software, and the money he made helped him pay for college.
Gross grew up in the San Fernando Valley in Los Angeles. When he was 15, in 1973, gas was rationed after OPEC imposed an oil embargo against the United States in order to punish the U.S. for providing support to Israel in the Arab-Israel war.
“You only could buy five dollars of gasoline per day. And I remember that my mother couldn’t buy enough gasoline to drive me to school,” Gross told CNBC in a video interview earlier in the fall.
So Gross had to ride his bike to high school. “As I’m riding both ways on the bicycle, I’m sitting here thinking, ‘It’s crazy that there’s somewhere else in the world that could decide to cut off your fuel supply, the thing that people need for their livelihood.’ I didn’t understand anything about climate change, or energy or anything. I just thought, ‘Someone else could do that?! That’s crazy.'”
This thought is still relevant now almost 50 years later, as Russia has cut off supplies of gas it is sending to Europe in response to the Ukraine war.
Gross went to the library after school to read about alternative renewable forms of energy such as solar energy and wind energy in the likes of Popular Science or Scientific American magazines. He got excited about the idea of renewable energy, had just taken trigonometry in school and used his newfound knowledge of both to make a couple of devices based on the idea of catching the sunlight and concentrating it.

One device he made was a parabola-shaped solar concentrator that could be used to create a solar oven or solar cooker. The other was a Stirling engine, which converts heat energy into kinetic or mechanical energy.
“Because I was reading Popular Science magazine, I saw people used to take out little ads in the back,” Gross told CNBC. “And I had $400 of bar mitzvah money leftover, so I took out a small add in the back of Popular Science advertising ‘Kits and plans to make your own solar concentrator,’ and I started selling them!”
He would go on to sell 10,000 of these plans and kits starting at $4 apiece. Personal computers didn’t yet exist, so he typed the material on a typewriter and made the drawings himself by hand.

He put what he made towards his college tuition. People from all over the country bought the kits and would send Gross a check or cash. It was his first foray into entrepreneurship, which was exciting, he said, and the experience served to change the trajectory of his life in other ways, too.
“I was really passionate about it back then. It really affected my life,” Gross told CNBC. “I wrote about that little business I started — it was called Solar Devices — on my application to college and it got me into CalTech. So it probably had a huge impact on my direction.”
For a long time, ‘nobody cared’
Gross studied mechanical engineering at CalTech while continuing to run the Solar Devices business during his first year, but then college got too demanding and he couldn’t keep up with running the business. Gross graduated from CalTech in 1981, right around the time IBM released its first mass-market personal computer.

“I have these two seminal things that happen in my life: The Arab oil embargo and now the PC is invented basically on my day of graduation in 1981,” Gross told CNBC. “So I went down and bought an IBM PC. And I started learning how to program and I had a detour for 20 years doing software.”
Gross’ detour into software started in the early 1980’s when he wrote accounting software inside of Lotus 1-2-3 to help manage his business making and selling high-performance loudspeakers. He started selling that software for $695. Gross, his brother and two CalTech friends came up with a natural language interface to Lotus 1-2-3, which they showed off at a Las Vegas tech show in 1985. Lotus ended up acquiring the product (and the four of them) for $10 million.
Gross later founded an educational software company and sold it to Vivendi for $90 million, then started tech incubator Idealab at the dawn of the dot-com boom. In the early 2000s, he decided to begin to pivot back to climate tech, this time with some money in the bank.

He started doing research and development in the space, but there wasn’t enough demand for solar energy tech. “I was way too early. No one cared,” Gross told CNBC.
“I remember I was working on this when Al Gore came out with ‘Inconvenient Truth.’ Still, nobody cared. I remember working on this in 2008 during the recession, nobody cared. I remember in the early 2010, 2012, people started talking about it, but there was no Greta yet,” Gross said, referring to the climate activist Greta Thunberg, who started protesting a lack of climate change action in 2018. “There was no movement. And certainly there was no inflation Reduction Act, which is a game changer,” Gross said.
In 2010, Gross heard Bill Gates speak at a TED conference about needing to make energy and energy storage cheaper. After that talk, Gross approached Gates and shared his idea of using computational power to improve the efficiency of solar power. Gates ended up investing in Gross’s idea, seeing the potential to replace many industrial processes that require high heat and burn fossil fuels to get there.
In 2013, Gross launched Heliogen, which uses artificial intelligence to position a collection of mirrors located in a circle around a central tower to reflect the sunlight back with maximum impact.
One critical component of Heliogen’s approach is built-in energy storage. One limiting factor for solar energy is its intermittency, which means it only delivers power when the sun is shining. But Heliogen stores energy as heat in a thermos of rocks — something traditional solar panels cannot do without batteries, as they turn the sun’s rays immediately into electricity.
“We’re gathering the energy when the sun is out. But we’re delivering the energy continuously because the energy is coming out of the rock bed,” Gross told CNBC. “And basically we are recharging the rock bed, like you would recharge your battery. The difference is a battery expensive, and rock bed is cheap.”
In 2019, Heliogen announced it had successfully concentrated solar energy to temperatures over 1,832 degrees Fahrenheit.

“Heliogen is the culmination of my life’s work,” Gross told CNBC, because it uses both software and renewable energy expertise.
The company had its first prototype in 2015, “but then, still, nobody cared. Couldn’t get any customers,” Gross said. He did get a couple of customers, but, it was still “struggling, struggling, struggling.” By 2019, Heliogen had the first large-scale system built and this time, “the world went crazy,” Gross said. “We got so much press and publicity, and customers started calling us all over who wanted to replace fossil fuels with concentrated sunlight, and then Covid hit,” Gross said.
After a bit of a Covid slowdown, interest started picking up again as the urgency around decarbonizing mounted and as energy price volatility made companies rethink their energy supply strategies, Gross said. The company went public via SPAC in a deal that landed $188 million of gross cash proceeds to Heliogen and on Dec. 31, 2021, Heliogen started trading.
The company is not yet profitable, losing $108 million in the first nine months of the year, but that’s expected as the company scales, according to Gross.
“We projected we would run at a loss for the few years of operation as we drive down the cost with volume production and the renewable energy production learning curve,” Gross told CNBC.
Heliogen’s first commercial grade project is in the final stages of permitting and aims to break ground next year in Mojave, California. The concentrated solar field is funded with $50 million from Woodside Energy, a wholly owned subsidiary of the Australian energy producer Woodside Petroleum, and $39 million from the U.S. Department of Energy.

While Gross has been ahead of the curve for most of his climate career, he’s confident the industry is catching up with him now. As the urgency surrounding climate change has become more widely understood, corporate executives face pressure from stakeholders to clean up their corporate emissions.
“But then the final straw was price of fossil fuels went up like crazy. The price of fossil fuels after Russia invaded Ukraine is a game changer,” Gross told CNBC. “Now, it’s not just for CO2 emissions, now you can save money. Now, this is the ultimate thing, which is make the energy transition be about reducing your cost, not about increasing your cost.”
There’s no time to waste.
“When I was a teenager, there was 320 parts per million of CO2 in the atmosphere,” said Gross, who is now 64 years old. “And today, there are 420.”
As Texas braces for tighter power margins and record demand on the ERCOT grid, Sunrun and NRG Energy are transforming home batteries into a giant virtual power plant. The two companies are integrating more home battery storage into the grid and tapping those batteries when the state needs power the most.
The solar + storage provider and energy company announced a new multi-year partnership aimed at accelerating the adoption of distributed energy in Texas, with a focus on solar-plus-storage systems that can be aggregated and dispatched during periods of high demand. The idea is simple: use home batteries as a flexible, on‑demand power source to help meet Texas’s rapidly growing electricity needs.
Under the deal, Texas homeowners will be offered a bundled home energy setup that pairs Sunrun’s solar and battery systems with retail electricity plans from NRG’s Texas provider, Reliant. Customers will also get smart battery programming designed to optimize when their batteries charge and discharge. As new and existing Sunrun customers enroll with Reliant, their combined battery capacity will be made available to support the ERCOT grid during times of stress.
“This partnership is a major step in achieving our goal of creating a 1 GW virtual power plant by 2035,” said Brad Bentley, President of NRG Consumer. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid.”
Sunrun, which has one of the largest fleets of residential batteries in the US, will be paid for aggregating the capacity, and participating Reliant customers will be compensated by Sunrun for sharing their stored solar energy.
The arrangement gives Texas households a way to earn money from their batteries while also improving grid reliability in a state that continues to see rapid population growth, extreme weather, and rising electricity demand.

Volkswagen is gearing up to launch a new family of affordable EVs, starting with the ID.Polo. Can it fill the shoes of the popular low-cost hatch?
Volkswagen announces ID.Polo EV range and more
The ID.Polo will be the first of four new entry-level electric vehicles that Volkswagen plans to launch, starting in Spring 2026.
The electric Polo “marks the beginning of a new generation of Volkswagen,” the brand’s CEO, Thomas Schäfer, said. The Polo is one of the best-selling VW models of all time, and its electric successor promises to build upon its legacy.
It will be the first “ID” model to bear an established Volkswagen name. Although it’s about the same size as its predecessor at 4,053 mm long, 1,816 mm wide, and 1,530 mm tall, with a wheelbase of 2,600 mm, the Polo EV offers more interior space.
Thanks to its compact drive modules, the electric Polo offers an extra 19 mm of interior length, which is “particularly noticeable in the rear.”
The luggage compartment is 24% larger than the classic Polo, with 435 L, up from 351 L. Folding the rear seats opens up 1,243 L of load volume, up from 1,125 L.
According to Volkswagen, the electric ID.Polo is “more versatile than any of its predecessors,” making it the perfect EV for getting around the city or as an everyday driver.
The Volkswagen ID.Polo will initially be available with three power outputs: 85 kW (114 hp), 99 kW (133 hp), and 155 kW (208 hp), while a sporty GTI variant will follow later in 2026 with 166 kW (223 hp).
The 85 kW and 99 kW versions will be equipped with a 37 kWh lithium iron phosphate (LFP) battery, while the 155 kW and 166 kW versions will be powered by a 52 kWh nickel manganese cobalt (NMC) battery, which Volkswagen said will deliver up to 450 km (280 miles) WLTP driving range. It will also support DC charging speeds up to 130 kW.
Based on a new MEB+ platform, Volkswagen promises that the new, highly efficient electric drive will reduce costs and energy consumption.
The new PowerCo unified cell uses cell-to-pack technology, combining cells directly into the battery pack. Volkswagen said the new design reduces costs, saves space, and unlocks more range while increasing energy density by about 10%.
VW’s MEB+ platform will also introduce new advanced driver assistance systems (ADAS) features, including a drastically improved Travel Assist. The ID.Polo will also be the first VW model to offer traffic light and stop sign recognition.
Can it live up to the task?
According to Autocar, which got the chance to test a prototype, the ID.Polo “feels remarkably like the current Polo. Switch from the petrol Polo into this and, a lack of engine noise aside, you would barely notice the difference.”
The reviewer, James Attwood, said the electric Polo delivered a “genuinely impressive ride for a car of this size,” adding it “drives and feels like you’d expect a Volkswagen to.”
With an affordable price tag, “the ID.Polo should be a strong all-rounder among the pack of small EVs suddenly battling for attention,” Attwood explained.
“It has a classically Volkswagen feel, poise and maturity, and blends a pleasingly mature driving experience with decent practicality and a reassuringly solid feel,” he said, adding, “A Volkswagen that feels like a Volkswagen, then. For that alone, it should be a winner.”
Others who got an early taste of the ID.Polo reported similar thoughts, including Auto Express, which said it “shows VW at its best.”
“Solid, well connected, comfortable and even quite engaging to drive, the ability to build all of this into a well-priced package is something we all hoped for; the surprising bit is how much of VW’s innate ‘character’ has come through,” Jordan Katsianis said after testing the pre-production prototype.
The ID.Polo will launch in Europe in Spring 2026 with prices starting from 25,000 euros ($29,500). It will be the first of four new affordable Volkswagen EVs, followed by the ID.Cross SUV and the smaller ID.1 electric car.
Although Volkswagen has yet confirm it, the ID.Polo is (sadly) not expected to launch in the US. It’s an affordable electric car aimed at Europe’s growing entry-level EV segment. Given the recent policy changes under the Trump administration and America’s love for big trucks and SUVs, don’t expect to see the electric Polo successor in the US anytime soon.

BYD offered a first look at its new flagship electric SUV and sedan, claiming the new EVs redefine high-end standards.
BYD preps to launch new flagship EV sedan and SUV
With over 480,000 new energy vehicles (NEVs) sold in November, BYD is coming off its best sales month of 2025. With new technology and vehicles launching across multiple segments, the company expects momentum to pick up in 2026.
That will include a pair of high-end flagship EVs, the Seal 08 sedan and Sealion 08 SUV. BYD confirmed the names for the first time on Monday alongside teaser images revealing the silhouette of each.
According to CarNewsChina, both models are set to debut in the first three months of 2026 and will feature BYD’s latest tech and software.
Both models are based on the Ocean S concept BYD revealed in April at the Shanghai Auto Show, featuring its latest design theme, Ocean Aesthetic 2.0.
Although China’s MIIT released a sales license for a BYD vehicle named the Seal 08 earlier this year, it launched as the Seal 06 EV this summer.
At 4,720 mm long, 1,880 mm wide, and 1,495 mm tall, the electric sedan is about the size of the Tesla Model 3. It’s offered with 46.1 kWh or 56.6 kWh battery packs, delivering a CLTC range of 470 km and 545 km, respectively.
Although BYD has yet to reveal prices or any other details, the Seal 08 is expected to deliver a longer driving range with added power.
Local news outlet 163 claims the new Sealion 08 will be 5,040 mm long, or slightly bigger than the Tesla Model Y-sized Sealion 07 SUV.
The new flagship SUV and sedan will join other BYD Ocean Series models, including the Seagull, Dolphin, Seal, and Song Plus.
Although November was BYD’s best sales month of the year, growth has slowed in 2025. BYD’s chairman and president, Wang Chuanfu, told investors (via CnEVPost) that the company’s biggest advantage lies in its advanced technologies, including next-gen batteries, smart driving features, charging, and other related EV tech.
“I say our technology isn’t sufficiently advanced now because we have major technological announcements coming, but I can’t disclose details at this time,” Wang said earlier this month.
BYD is also aggressively expanding overseas to drive growth. Last month, BYD’s exports surged 325% with a record nearly 132,000 vehicles shipped overseas.
