Tesla recently showed off Giga Small Haus, an interesting new display project hosted at Giga Berlin. The small new house is located just outside the main entrance of Tesla’s Giga Berlin factory, with a Quicksilver Model Y parked inside.
Giga Small Haus is powered only by solar and Powerwall 3 - disconnected from the local grid and from Giga Berlin itself. It serves as a live demonstration of Tesla Solar and Tesla’s Powerwall battery backup.

The centerpiece of the display is a Model Y in Quicksilver - a beautiful pick for a beautifully lit house. However, that’s not the real focus here - it's the Powerwall and Gateway on the wall.
The Powerwall is the focus of Giga Small Haus, and there’s a display with some additional information on the wall. Part of the display also includes a screen that displays the current output of the Powerwall itself versus the consumption of Giga Small Haus, as well as the input from solar.

Not a Tesla App
The text on the exhibit is divided into several sections. Here’s a translated and edited version of what we can see from Tesla’s images. Some additional text is obscured. If someone visits Giga Small Haus, let us know.
Powerwall
Powerwall is a home battery system that stores energy from solar panels, the electrical grid, or during off-peak hours and powers your home during the day or during a power outage.
With Powerwall, you can use self-generated solar energy during the day and night, thus avoiding high electricity costs. You can also store excess energy produced during sunny periods for use during times of low production or power outages.
Key Features
Energy Storage: Powerwall stores excess energy from solar panels or the grid for later use or during power outages.
Backup Power: In the event of a power outage, Powerwall automatically switches to battery power to ensure continuous power supply.
Integration: Powerwall can be seamlessly integrated with existing solar systems and other power sources.
Scalability: Multiple Powerwalls can be installed to meet higher energy storage needs.
Smart Energy Management: Powerwall works with Tesla's software to optimize energy consumption and reduce costs.
How Powerwall Works
Storage: During the day, when solar panels produce more energy than needed, the excess is stored in Powerwall.
Usage: At night or during times of low solar production, the stored energy is used to power the home, reducing reliance on the grid.
Backup: During a power outage, Powerwall automatically provides power to critical circuits, ensuring continuous operation of essential appliances.
Benefits
Cost Savings: By storing and using solar energy, you can reduce your electricity bills.
Reliability: Provides backup power during outages, ensuring your home remains powered.
Sustainability: Promotes the use of renewable energy by storing excess solar production for later use.
Overall, Giga Small Haus is an interesting real-life demo of what Powerwall and Solar can accomplish. It would be neat if Tesla built more of these displays - perhaps near major Delivery and Service Centers and at Giga Texas, Fremont, Giga Shanghai, and other facilities. Many Tesla owners have yet to learn about and experience some of Tesla’s Energy products.

Tesla has just opened up their Early Access Program, which we found out about just a few days ago - to FSD owners and subscribers in the United States. This new Early Access Program will offer regular owners the ability to get early FSD updates before they get widely released.
Early Access
Tesla has begun to slowly roll out a pop-up (and button) in the Tesla app, offering users the ability to enroll in the FSD (Supervised) Early Access Program in the United States. This update is rolling out slowly, so don’t be surprised if you don’t have it yet.
For now, this program appears to be limited to the United States. Users in Canada and Mexico, even those with existing Early Access, have not yet received an invite to the program.
Once you join the Early Access Program, at the very bottom of your app, where your VIN and software version normally appear, you’ll see a new “Early Access” link. Tapping this will show your status as a member of the Early Access program and also offers you the opportunity to leave the program if so desired.

How to Get In?
To be offered the program, you must own an AI4/Hardware 4 vehicle with FSD, either purchased or actively subscribed. Unfortunately, HW3 owners are not receiving this right now.
A pop-up will be displayed in your Tesla app once you get selected to join the program. If you dismiss the pop-up in a hurry, don’t worry. The ability to join Early Access stays as in the image below, and you can join the program at any time.
Ending your subscription while part of Early Access means your vehicle will be removed from the program.

Privacy
In exchange for receiving early builds of FSD, Tesla will increase the amount of data, video, and audio gathered from your vehicle, and the data will be VIN-associated, meaning less privacy and anonymity for users.
Any software updates or release notes you receive, both in-vehicle and in-app, will be watermarked with your vehicle's VIN. Tesla has been watermarking employee release notes since June of 2024 to reduce leaks, and this new Early Access program appears to follow a similar format, even though it is more widespread.

Cautions
Of course, earlier FSD builds are usually less stable and potentially less safe than wide release, so it’s important to remain more vigilant during FSD’s use. If anyone else uses the vehicle, make sure they’re also aware of the situation.
On the flip side, this is really exciting for many Tesla owners. Tesla’s Early Access program has normally been limited to employees and influencers, so it’s awesome to see regular owners getting an opportunity to get in on all the fun of testing out Tesla’s latest FSD functionality.
This new Early Access program could also mean that Tesla has a new level of confidence in future builds, where it’s now willing to make them available to more users. It could also have to do with Tesla’s FSD Unsupervised ambitions, where they may need more data than was already collected in order to successfully launch their Robotaxi this June.
Emissions Pooling is an incentive-based program supported by various governments—most notably the European Union—to help automakers meet strict carbon reduction goals under Corporate Average Fuel Economy (CAFE) standards.
CAFE standards mandate that automakers reduce the average CO₂ emissions across their fleet of newly manufactured vehicles. The EU’s 2025 targets are particularly aggressive, and manufacturers risk hefty fines if a sufficient portion of their new vehicles aren’t low- or zero-emission.
Emission Pool
Emissions pooling is a regulatory mechanism that allows automakers to combine their fleet CO₂ emissions to collectively meet environmental targets. Companies with low or zero emissions—like Tesla—can partner with higher-emitting automakers to help reduce their combined average and avoid costly fines.
In practice, this means pool members purchase emissions credits from Tesla, which uses its all-electric lineup to generate surplus credits. These credits help other manufacturers offset their emissions, while Tesla earns a tidy profit.
Tesla has long capitalized on this model, regularly selling emissions credits to strengthen its financials. Now, its European Union emissions pool is expanding again—with Honda and Suzuki joining existing members like Stellantis, Toyota, Ford, Mazda, and Subaru.
Green Bottom Line
Every automaker in Tesla’s emissions pool is effectively buying credits from a company with a 100% zero-emission fleet. In Q4 2024 alone, Tesla earned $692 million from regulatory and emissions credits, making up nearly 30% of its quarterly net income.
That’s a major chunk of profit driven by programs like emissions pooling—and with Honda now onboard, Tesla gains a significant new partner (and revenue stream) in the EU.
