Bitcoin is a digital currency. Whether that is a good thing or not is beside the point. What is important is that as a creature of the digital world, it relies on servers powered by electricity for its existence — a lot of them. Even though the use of renewable energy has surged in the past decade, the majority of electricity today still comes from burning fossil fuels, mostly coal. That means the digital world we have created — all our cell phones, streaming TV, video games, internet of things, and yes, bitcoin — creates lots of carbon emissions.

According to the BBC, the carbon footprint of our gadgets, the internet, and the systems supporting them account for about 3.7% of global greenhouse emissions — about the same as the airline industry. But the problem is expanding. Mike Hazas, a researcher at Lancaster University, tells the BBC emissions from digital devices are expected to double by 2025.

Bitcoin goes beyond being a digital currency, though. It’s extra energy intensive on purpose — bitcoin mining is supposed to be hard and costly.

In March, Tesla shocked the world when it said it would begin allowing customers to pay for their cars using bitcoin. 6 weeks later, the company reversed course and stopped accepting bitcoin for purchases. In a statement, Elon Musk said, “Tesla has suspended vehicle purchases using bitcoin. We are concerned about rapidly increasing use of fossil fuels for bitcoin mining and transactions, especially coal, which has the worst emissions of any fuel.

“Cryptocurrency is a good idea on many levels and we believe it has a promising future, but this cannot come at great cost to the environment. Tesla will not be selling any bitcoin and we intend to use it for transactions as soon as mining transitions to a more sustainable energy. We are also looking at other cryptocurrencies that use <1% of bitcoin’s energy/transaction.”

But now it appears Tesla and Musk have rethought their position. On Wednesday, Musk told a “B Word” conference that Tesla will most likely start accepting bitcoin again.

“I wanted a little bit more due diligence to confirm that the percentage of renewable energy usage is most likely at or above 50%, and that there is a trend towards increasing that number, and if so, Tesla would resume accepting bitcoin. Most likely the answer is that Tesla would resume accepting bitcoin. Tesla’s mission is accelerating the advent of sustainable energy. We can’t be the company that does that and also not do appropriate diligence on the energy usage of bitcoin.”

Editor’s note: The issue isn’t ONLY what type of power plant powers miners. Every serious/decent/real plan showing how we can get the climate crisis under control indicates that we need to massively reduce energy use while we quickly scale of renewable energy projects. Bitcoin drives us in the opposite direction, as it’s extremely, ridiculous, insanely energy intensive. Jacking up energy demand means that the solar panels and wind turbines we feverishly produce will be used to satisfy increasing energy demand more than to retire fossil fuel power plants. It’s just not a good idea.

Musk added that he personally owns bitcoin, ethereum, and dogecoin, separate and apart from the bitcoin that Tesla and SpaceX own. “I might pump, but I don’t dump,” Musk said. “I definitely do not believe in getting the price high and selling. I would like to see bitcoin succeed.”

Kia EV4 test drive reveals the good, the bad, and the ugly

Kia EV4 test drive reveals the good, the bad, and the ugly

Can Kia’s first electric sedan live up to the hype? After launching the EV4 in Korea, we are finally seeing it in action. A new test drive of the EV4 gives us a closer look at what to expect as Kia prepares to take it global. Here’s how it went down.

Kia EV4 test drive: The good, the bad, and the ugly

Kia claims the EV4 will “set a new standard in electric vehicles” with long-range capabilities, fast charging, and a sleek new design.

The electric sedan features a unique, almost sports-car-like profile with a long-tail silhouette and added roof spoiler.

Kia claims it is “the new look of a sedan fit for the era of electrification.” Despite its four-door design, the company is calling it a new type of sedan.

The design is not only eye-catching, but it’s also super efficient. With a drag coefficient of just 0.23, the EV4 is Kia’s most aerodynamic vehicle so far, enabling maximum driving range and efficiency.

Kia opened EV4 orders in South Korea in March, starting at about $29,000 (41.92 million won). It’s available with two battery options: 58.2 kWh and 81.4 kWh. The entry-level “Standard Air” model, powered by the 58.2 kWh battery, is rated with up to 237 miles of driving range.

The “Long-Range Air” variant starts at 46.29 million won ($31,800) and has a driving range of up to 331 miles (533 km) in Korea.

With charging speeds of up to 350 kW, the EV4 can charge from 10% to 80% in around 29 minutes. The long-range battery will take about 31 minutes.

The interior boasts Kia’s latest ccNC infotainment system with a 30″ Ultra-wide Panoramic Display. The setup includes dual 12.3″ driver displays, navigation screens, and a 5″ air conditioning panel.

With deliveries kicking off, we are seeing some of the first test drives come out. A review from HealerTV gives us a better idea of what it’s like to drive the EV4 in person.

Sitting next to Kia’s first pickup, the Tasman, the reviewer mentions the EV4 feels “particularly newer.” The test drive starts around the city with a ride quality similar to that of the K5, if not even better.

As you can see from the camera shaking, the ride feels “a bit uncomfortable” on rough roads. However, on normal surfaces and speed bumps, Kia’s electric sedan “feels neither too soft nor too hard,” just normal. The reviewer calls the EV4’s overall ride quality “quite ordinary” with “nothing particularly special about it.”

When accelerating, the electric car was smooth in the beginning but felt “a little lacking in later stages.” Overall, it should be enough for everyday use.

One of the biggest issues was that the rear window appeared too low. The rear brake lights also stick out, making it hard to see clearly through the rearview.

Keep in mind that the test drive was the Korean-spec EV4. Kia will launch the EV4 in Europe later this year and in the US in early 2026.

In the US, the EV4 will include a built-in NACS port for charging at Tesla Superchargers and a driving range of up to 330 (EPA-est) miles. Prices will be revealed closer to launch, but the EV4 is expected to start at around $35,000 to $40,000.

Would you buy Kia’s electric sedan for around $35,000? Or would you rather have the Tesla Model 3, which starts at $42,490 in the US and has up to 363 miles of range? Let us know in the comments.

Hyundai’s 2026 IONIQ 9 EV lease and incentives just dropped – here’s what you’ll pay

Hyundai’s 2026 IONIQ 9 EV lease and incentives just dropped – here's what you’ll pay

Hyundai’s 2026 IONIQ 9 EV is launching with a lease deal, affordable rates, and a big rebate, making the automaker’s largest EV a competitive choice.

Leasing a 2026 Hyundai IONIQ 9

CarsDirect reports that, according to a bulletin sent to dealers, the 2026 Hyundai IONIQ 9 S is $419 for 36 months with $4,999 due at signing based on 10,000 miles a year. That makes the effective cost of the nationally available lease $558 monthly. 

That’s slightly more expensive than the Model Y Long Range Rear-Wheel Drive, which debuted this week. It can be leased for $399 with $4,093 at signing or $513 per month. That’s a price difference of only $45 per month, potentially making the IONIQ 9 a better value, since Hyundai’s first three-row electric SUV gives you more car for the money.

The IONIQ 9 offers 335 miles of driving range, fast charging capabilities, room for seven, and prices start at $60,555.

Financing and incentives

Hyundai isn’t offering rebates on the IONIQ 9, but good news – it qualifies for the $7,500 federal EV tax credit because it’s manufactured in Georgia.

The IONIQ 9 has national financing rates as low as 1.99% APR for up to 60 months. For a lower monthly payment, there’s a 72-month option at 2.99%. Compare that to the most affordable 2026 Tesla Model Y, which has a 72-month option at 5.49% APR, and it shows what a good deal it is.

There’s also a $5,000 financing incentive available, but you have to choose a loan at a higher interest rate to get it. The $5,000 Dealer Choice Bonus helps lower prices if you finance at 5.99% for 60 months and 6.59% for 72 months. 

However, it’s cheaper to opt for the 1.99% APR deal instead of the Dealer Choice Bonus and higher interest rate; CarsDirect found that the 1.99% APR could save IONIQ 9 buyers up to $2,200:

On a 5-year loan at 1.99%, we estimate the IONIQ 9 would cost $63,084. With the APR and rebate combo, it would cost $63,783. Here, opting for the lower rate would save buyers roughly $700. But that’s not the whole story. That’s because Dealer Choice offers, available on many Hyundais, allow a mark-up of up to 1%.

As a result, the $5,000 rebate and higher rate of 6.99% could cost buyers over $2,200 more than simply taking the lower rate to begin with.
