Last quarter, Tesla installed 85 megawatts (MW) of rooftop solar power across the United States. That’s up from a mere 26 MW in Q2 2020. Of course, Q2 2020 was plagued by the covid-19 pandemic and ensuing lockdowns. (Bad pun somewhat intended.) Nonetheless, a more than tripling of solar power installations is a big step up.

Energy storage deployments grew to a similarly large degree, from 419 GWh in Q2 2020 to 1274 GWh in Q2 2021.

However, these figures alone don’t tell the full story — perhaps not much at all.

Table from Tesla Q2 2021 Update

It typically takes months and months from the time that someone orders a rooftop solar system from Tesla to the day it actually goes online and starts generating electricity for them. After you buy a system, Tesla has to get a team out there to put it on your roof. That can take a while, and is especially dependent on the ratio between workers in the area who can perform a solar installation and the level of consumer demand for such solar systems.

But that may not even be the lengthiest part of the process (and wait) for most new solar buyers. In some places in the US, the permitting process can take just a few days less than forever. In many other places in the US, it can take weeks or months (as in, several months). There are not many places where it happens in the course of a week. Europe and Australia don’t seem to have a permitting problem anything like this. Permits are quick and easy. The US, for some reason, is slow to adapt.

On the plus side, that means there’s plenty of room for improvement in the US — which can bring costs down considerably. On the down side, the US is far behind. …

One promising initiative is the new SolarAPP+ initiative. It is helping to streamline the solar permitting process in places around the country. As simple as it sounds, this is one of the most exciting developments in the US solar industry in years. Thanks is due for all the people involved to make it happen. And on the topic of Tesla, note that Tesla was quite involved in the development of the program. Check out my interview with Amber D’Ottavio, Vice President of Product Management at Accela, to hear more:

I’ve been shocked, to be honest, at how slowly Tesla solar installations are getting both installed and permitted. Hopefully this is an area that can get quicker and quicker in the coming few years.

In the meantime, 85 MW of solar ain’t nothin’. That’s 85 MW of clean, homegrown power capacity that can create electricity from sunlight — and can also then power your electric car. Of all the many wonderful things in the cleantech industry, I’m not sure if anything beats the phrase “I’m driving on sunshine” or “I’m driving on sunlight.”

NextEra working with Exxon to develop gigawatt data center for hyperscaler

Dado Ruvic | Reuters

NextEra Energy is partnering with Exxon Mobil, the country’s largest oil company, to build a large data center site powered by natural gas for a potential tech customer, CEO John Ketchum told investors Monday

The 1.2 gigawatt power plant would combine gas generation with Exxon’s carbon capture technology to reduce emissions, according to NextEra’s presentation to investors.

They plan to market the site to a hyperscaler in the first quarter of 2026. Hyperscalers are the big tech companies that are building data centers to train and run artificial intelligence applications. There is no signed agreement with a hyperscaler yet.

NextEra and Exxon have secured 2,500 acres of land for the facility. The site will be located in the Southeast in close proximity to Exxon’s carbon-dioxide pipeline infrastructure, according to NextEra.

NextEra is the largest renewable energy developer in the U.S., but it is leaning into natural gas to meet the growing demand from data centers. The power company plans to bring as much as eight gigawatts of gas generation online by 2032, and is developing a pipeline of 20 gigwatts of gas generation.

NextEra plans to build 15 gigawatts of power for data center hubs by 2035, Ketchum said. That includes at least three data center campuses that NextEra is developing with Alphabet‘s Google.

“A lot of those will get started with what I call bridge power — renewables, storage,” the CEO said. “We’re also at that same time planning for the gas to come behind it.”

The tech sector has primarily secured renewables and increasingly nuclear power to supply data centers in an effort to meet its climate targets.

The Mercedes CLA EV crushes real-world range test, driving 434 miles

Mercedes calls it the “one-liter” car for a reason. The new Mercedes CLA EV has an impressive EPA range of 374 miles, but in real-world driving, it can go even further.

Mercedes CLA EV beats EPA range in real-world driving

The new CLA EV might just be the most critical Mercedes model yet. It’s the first of the luxury brand’s latest generation of electric vehicles, promising to be much more advanced, efficient, and refined than ever before.

Powered by an 85 kWh battery pack, the 2026 Mercedes-Benz CLA 250+ has an EPA-estimated range of 374 miles.

Although that’s already among the highest for any 2026 model-year EV in the US, the electric CLA can drive even further in the real world.

The folks at Edmunds just got their hands on one to test it out. In the Edmunds EV Range Test, the 2026 Mercedes CLA EV crushed its EPA figures, driving an impressive 434 miles on a single charge, beating its official ratings by 16%.

Out of 13 Mercedes models Edmunds has tested, the new CLA EV had the second-longest driving range, trailing only the EQS 450+. However, given that the EQS is a full-size sedan and significantly more expensive than the CLA, it’s expected.

The 2026 Tesla Model 3 Standard went 339 miles, while the 2026 Audi A6 E-tron drove 402 miles during the EV Range Test.

The Edmunds EV Range Test is 60% city and 40% highway driving with an average speed of 40 mph. Each vehicle is set to the most efficient drive setting, while the climate control is set to 72 degrees to reflect the most accurate real-world driving conditions drivers encounter each day.

During the test, the electric CLA used 23.2 kWh per 100 miles of driving, beating the EPA’s estimates by 16.5%.

On the Edmunds EV Charging Test, it had an average charge rate of 193 kW from 10% to 80%, earning a score of 833 miles per hour. That’s the second-best of those tested, behind the Hyundai IONIQ 6.

The new Mercedes CLA EV is now the least expensive car they’ve tested, with over 400 miles of range. Last week, Mercedes launched the 2026 CLA 250+ EV, starting at $47,250.

Mercedes said it will begin delivering the first customer models this month, with output ramping up throughout early 2026.

Tesla (TSLA) goes all out with new incentives in end-of-year sales push

Tesla (TSLA) goes all out with new incentives in end-of-year sales push

Tesla is pulling every demand lever available as we head into the final weeks of the year. The automaker has launched a new set of aggressive incentives in the US, including free upgrades on inventory vehicles, 0% APR financing, and $0 down leases.

It’s the end of the quarter (and year), and as per usual, Tesla is trying to empty its inventory, but it’s more difficult this year due to the end of the tax credit in Q3 pulling a lot of demand away from Q4.

We have regularly reported on Tesla ramping up incentives at the end of the year, but this new batch is arguably the most aggressive we have seen in a long time.

First off, Tesla is offering one free upgrade on eligible inventory vehicles.

If you go to Tesla’s inventory page for Model 3 or Model Y, you will see a lot of vehicles listed with a “Free Upgrade” tag. This basically means that if you pick a car that has a paid option, like a premium paint color (Ultra Red or Quicksilver), 20″ Induction wheels, or the White interior, Tesla is waiving the cost of that option.

That’s a value of anywhere from $1,000 to $2,500 depending on the option.

On top of that, Tesla has expanded its financing offers. The company is now offering 0% APR financing for up to 72 months on Model 3 and Model Y purchases.

This is a significant move. We have seen low interest rates before, but 0% for 72 months is basically free money, especially in the current interest rate environment.

But wait, there’s more.

For those looking to lease, Tesla has introduced $0 down leases for the Model Y.

Previously, Tesla required a down payment of at least $3,000 for its best lease rates. Now, you can drive off the lot with a Model Y for $0 down, though the monthly payments will obviously be higher than with a down payment.

Tesla writes on its website regarding the new push:

“Take delivery by December 31, 2025 to take advantage of these limited-time offers. Available on select inventory vehicles while supplies last.”

The automaker is clearly trying to deliver as many cars as possible before the ball drops on 2025.

Electrek’s Take

The end-of-year push is in full swing.

When you see Tesla stacking incentives like this, 0% financing, zero down, and free options, it tells you one thing: they have inventory to move.

With a lot of demand in the US pulled forward into Q3 due to the end of the tax credit for electric vehicles, it was always clear that Tesla would have trouble moving cars in Q4.

These are roughly the best end-of-quarter incentives we have ever seen, and even then, I’d be surprised if Tesla can come close to its record deliveries of last year’s Q4: 495,000 vehicles.
