People are at risk from food and water shortages, flooding, high heat, an increase in disease, and economic loss due to climate change. Conflict and human migration are potential outcomes. Climate change has been named the biggest threat to world health in the 21st century, and it’s clear that taking prompt action to lessen its effects is of the utmost importance.
Amongst the many actions we can take to reduce our carbon footprint and amount of harmful emissions that can be directly tied to us, purchasing an electric vehicle is one that could surely have a long-lasting effect.
Studies have found that the more drivers transition their gas cars to electric ones, the better for ozone levels and the decrease of particulate matter or “haze”. When EV adoption is coupled with switching our power generation to renewable energies, the positive impacts are even greater.
Back in 2011 the Tesla Roadster - the first serially produced lithium-ion battery vehicle - served as the face of the new EV Revolution and hinted at the possibility of fast, seductive, and opulent electric vehicles in the future. Worldwide sales of electric vehicles are now in the millions of units since its introduction, with Tesla accounting for almost 2 million of those sales.
But a high EV adoption rate not only means good news for the planet we currently live in. It also dramatically increases the survival chances of our children and grandchildren, the generations to come. According to a study published just last year in Nature Communications, "adding 4,434 metric tons of carbon dioxide in 2020 - equivalent to the lifetime emissions of 3.5 ordinary Americans - could cause one extra death globally in expectation during 2020-2100."
This is where electric vehicles can play their part. Let's look at Tesla's most recent impact report as an illustration. The average combustion vehicle emits 450 g CO2e every mile, or 68 metric tons over the course of a lifespan of 150,000 miles (241,401 km), according to that report. In contrast, the Model 3 emits 180 g CO2e/mile when charged through the American power grid, which is equivalent to 27 metric tons of carbon dioxide over the course of a lifetime.
We save around 40 metric tons of carbon over the course of a lifetime for every person who abandons their gas car for an electric vehicle. Tesla sales alone have saved our planet from around 80 million metric tons of carbon, assuming that most people would have gone with a gas car in an alternative universe where the electric revolution never happened.
According to the above-mentioned study, since every 4,000 metric tons of carbon emissions are predicted to result in an additional death, around 20,000 lives have been saved as a result. If we take into account the 10 million electric cars sold by other manufacturers, the number of lives saved increases to a staggering 120,000.
Human lives are not the only direct beneficiaries of a higher EV adoption rate, however. Another study published by Northwestern university found that if EVs replaced 25% of combustion-engine cars currently on the road, the United States would save approximately $17 billion annually by avoiding damages from climate change and air pollution. In more aggressive scenarios -- replacing 75% of cars with EVs and increasing renewable energy generation -- savings could reach as much as $70 billion annually.
Many EV detractors mention that the electricity used to charge EVs still comes from fossil fuels, and therefore it balances out tail-pipe emissions savings. But this is not an accurate picture. Some electric charging stations even use renewable energy to charge EVs nowadays. However, EVs still result in fewer emissions overall even when their charging is coal powered. For example, electric vehicle use has resulted in a 20% reduction in greenhouse gas emissions in nations that rely heavily on coal, like China.
And sure, if done carelessly, EV battery manufacture might be dangerous to the environment. Nearly all EV emissions are ‘well-to-wheel emissions’ created during the battery production process. Because EVs are still a relatively new technology, the energy sources used to make batteries do not conform to industry standards, which increases the carbon footprint. But things are starting to change in this regard.
Compared to two years ago, the carbon footprint of modern EV batteries is two to three times smaller, and it is getting cleaner all the time. EV automakers are establishing standards for the suppliers of their batteries. For instance, they mandate that vendors exclusively produce using renewable energy sources like solar and wind. These sources can supply the substantial energy required to make EV batteries without producing damaging pollutants. Tesla, for example, intends to produce its batteries with only renewable energy.
Taking all these factors into consideration, we can only hope the EV Revolution is here to stay. We no longer have the luxury of being shy when it comes to reducing emissions and pollutants that are clearly accelerating climate change, and even though sometimes it can be easy to feel like there is not much we can do as individuals to prevent this, driving electric, while pushing for broader adoption of renewable power sources (including inside our own homes) is definitely a start.

Tesla’s been on a roll with Supercharger improvements lately, from the 325kW charging update for the Cybertruck, to 500kW with V4 Superchargers coming next year. While those improvements have been limited to the Cybertruck, Tesla didn’t put all their focus on their new flagship vehicle, but looked at their more affordable vehicles as well.
LFP Battery Heating
Tesla’s Superchargers can now heat LFP Batteries - those that are in the Model 3 and Model Y Rear Wheel Drive variants. This applies to Long Range and Standard Range models, which saw a limited run. This is another update included as part of the 2024 Tesla Holiday Update - which really arrived with a lot of unannounced new features and capabilities.
The change is pretty interesting - Superchargers of the V3 and V4 variety can now pre-heat batteries for Model 3 and Model Y vehicles equipped with LFP battery packs. That means those vehicles are able to get back on the road faster when it's extremely cold. Of course, Tesla still advises you to precondition before you arrive, saving drivers time and money.
Max de Zegher, Tesla’s Director of Charging, also commented on the new feature. Essentially, Tesla is inducing an AC (alternating) ripple current through the battery to warm it up. Keep in mind that Superchargers are DC charging. That means it is possible to get a cold-soaked LFP vehicle on the road 4x faster than before, assuming that it didn’t precondition at all and that it is in the worst-case scenario (below 0ºF).
In essence, Tesla is using some engineering magic to turn the circuits inside the LFP battery into an electric heater - and powering that heater through the Supercharger. An AC ripple current is a small oscillation in the DC charging current that generates heat through electrical resistance, warming up the battery. Those ripples are a byproduct of converting AC to DC and back - so Tesla is using the onboard charger to induce those ripples to warm up the battery. Definitely an innovative technique that’s really only possible with the versatility of the NACS connector.
We’re hoping Tesla can implement this across their full lineup of vehicles, but we’ll have to wait and see how it is trialed across LFP vehicles first and if it is even possible on vehicles with 2170 or 4680 battery packs.
Tesla launched two FSD updates simultaneously on Saturday night, and what’s most interesting is that they arrived on the same software version. We’ll dig into that a little later, but for now, there’s good news for everyone. For Hardware 3 owners, FSD V12.6.1 is launching to all vehicles, including the Model 3 and Model Y. For AI4 owners, FSD V13.2.4 is launching, starting with the Cybertruck.
FSD V13.2.4
A new V13 build is now rolling out to the Cybertruck and is expected to arrive for the rest of the AI4 fleet soon. However, this build seems to be focused on bug fixes. There are no changes to the release notes for the Cybertruck with this release, and it’s unlikely to feature any changes when it arrives on other vehicles.
FSD V12.6.1 builds upon V12.6, which is the latest FSD version for HW3 vehicles. While FSD V12.6 was only released for the redesigned Model S and Model X with HW3, FSD V12.6.1 is adding support for the Model 3 and Model Y.
While this is only a bug-fix release for users coming from FSD V12.6, it includes massive improvements for anyone coming from an older FSD version. Two of the biggest changes are the new end-to-end highway stack that now utilizes FSD V12 for highway driving and a redesigned controller that allows FSD to drive “V13” smooth.
It also adds speed profiles, earlier lane changes, and more. You can read our in-depth look at all the changes in FSD V12.6.
Same Update, Multiple FSD Builds
What’s interesting about this software version is that it “includes" two FSD updates, V12.6.1 for HW3 and V13.2.4 for HW4 vehicles. While this is interesting, it’s less special when you understand what’s happening under the hood.
The vehicle’s firmware and Autopilot firmware are actually completely separate. While a vehicle downloading a firmware update may look like a singular process, it’s actually performing several functions during this period. First, it downloads the vehicle’s firmware. Upon unpacking the update, it’s instructed which Autopilot/FSD firmware should be downloaded.
While the FSD firmware is separate, the vehicle can’t download any FSD update. The FSD version is hard-coded in the vehicle’s firmware that was just downloaded. This helps Tesla keep the infotainment and Autopilot firmware tightly coupled, leading to fewer issues.
What we’re seeing here is that HW3 vehicles are being told to download one FSD version, while HW4 vehicles are being told to download a different version.
While this is the first time Tesla has had two FSD versions tied to the same vehicle software version, the process hasn’t actually changed, and what we’re seeing won’t lead to faster FSD updates or the ability to download FSD separately. What we’re seeing is the direct result of the divergence of HW3 and HW4.
While HW3/4 remained basically on the same FSD version until recently, it is now necessary to deploy different versions for the two platforms. We expect this to be the norm going forward, where HW3 will be on a much different version of FSD than HW4. While each update may not include two different FSD versions going forward, we may see it occasionally, depending on which features Autopilot is dependent on.
