Newsom touts California’s record battery energy gains at UN climate conference
California added 1,200 megawatts of battery energy storage to its electrical grid over the last six months, further building on its nation-leading capacity and pushing the state closer to its clean energy goals, officials said on Nov. 13.
Gov. Gavin Newsom announced the latest milestone while making the rounds at the United Nations Conference of the Parties climate summit in Belém, Brazil, where he is touting the state’s international climate leadership amid the notable absence of officials from the Trump administration.
With the latest additions, the Golden State has reached 16,942 megawatts of available battery storage—about one-third of the estimated capacity needed to reach its goal of 100% clean energy by 2045.
Battery energy storage systems capture excess wind and solar power and push it onto the grid during hours of peak demand, or when the sun isn’t shining or the wind isn’t blowing.
Newsom used the announcement as an opportunity to swipe at President Donald Trump, who has focused heavily on the growth of fossil fuels such as oil, gas and coal while simultaneously slashing funding for renewable energy projects in California and across the U.S.
“Donald Trump’s reckless energy agenda puts China first and America last—letting Beijing seize the global clean energy economy and the good-paying jobs, manufacturing, and economic prosperity that come with it,” the governor said in a statement. “California won’t stand by and watch.”
While China continues to burn fossil fuels, the country is breaking global records with its investments in renewable energy and battery storage. In 2024, China commissioned 37 gigawatts of battery storage, more than the combined additions of the U.S. and Europe, according to the energy think tank Ember.
But battery storage has also been transformative for California, helping the state avoid rolling blackouts and urgent calls for energy conservation, known as Flex Alerts, in the last several years. California now has more installed battery capacity than any other jurisdiction on the planet except for China, according to Newsom.
“We now dominate,” he said at a climate investors event in São Paulo before heading to Belém.
Experts say the state’s gains are impressive. The U.S. has about 37 gigawatts of total operating battery capacity, nearly half of which is in California, said Maia Leroy, founder of the energy consulting firm Lumenergy LLC.
“California is claiming a huge victory here,” Leroy said. She said the state’s capacity of 16,942 megawatts—or 16.9 gigawatts—is enough to power about 13 million homes for four hours, the typical duration of a battery.
The surge in storage is meeting with even faster growth of solar in the state. Together, solar plus batteries have eliminated more than 37% of fossil gas use on the state’s main grid, the California Independent System Operator, in just the last two years, according to Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford University.
“That is an enormous amount of batteries,” Jacobson said.
Energy storage is one of many ways California is hoping to stand out at this year’s COP summit. Representatives from the state—including Newsom, California Natural Resources Secretary Wade Crowfoot and Air Resources Board Chair Lauren Sanchez—have also entered into several partnerships and agreements with other regions and nations this week.
Among them is the Global Energy Storage and Grids Pledge, an initiative started at last year’s COP conference that sets a global target of deploying 1,500 gigawatts of energy storage and building about 15.5 million miles of new transmission infrastructure by 2030. California became the first subnational entity to join the pledge, which has been backed by more than 100 countries and organizations.
The pledge is a good start, but the world needs more than just storage and transmission, Jacobson said.
“California is moving faster than the U.S. as a whole, but to really make inroads, California needs to also electrify transport, industry and buildings as fast as it is building batteries, while growing offshore wind, utility solar, rooftop solar and enhanced geothermal,” he said.
The state is working toward those goals, including pushing forward with a major offshore wind project that lost nearly half a billion dollars in federal funding from the Trump administration this year.
Other agreements signed at COP so far this year include joint partnerships and memoranda of understanding with Colombia, Chile, Nigeria, the Brazilian state of Pará and the German state of Baden-Württemberg on issues such as wildfire prevention and response, sustainable urban transportation and greenhouse gas emission reductions.

Looking for the Best Smart Scale? Step on Up
Other Smart Scales
Renpho MorphoScan for $150: The Renpho MorphoScan full-body scanner looks surprisingly similar to the Runstar FG2015, including a near-identical display attached to the handlebars. Well, spoiler alert, they are basically the same scale. They even use the same app to collect data (and you can even use both scales simultaneously with it). The only reason this scale isn’t our top pick for the category is that it’s $15 more expensive. You can rest assured that a price war is looming.
Arboleaf Body Fat Scale CS20W for $40: This affordable Bluetooth scale isn’t the most eye-catching I’ve tested, owing to its big, silver electrodes and an oversized display that comes across as a bit garish. While weight is easy to make out, the six additional statistics showcased are difficult to read, all displayed simultaneously. I like the Arboleaf app better than the scale, where five more metrics can be found in addition to the seven above, each featuring a helpful explanation when tapping on it. It’s a solid deal at this price, but the upsell to get an “intelligent interpretation report” for an extra $40 per year is probably safe to skip.
Hume Health Body Pod for $183: Hume Health’s Body Pod, another full-body scanner with handles, is heavily advertised—at least to the apps on my phone—and touted (by Hume) as the Next Big Thing in the world of body management. While the app is indeed glossy and inviting, I was shocked to discover how flimsy the hardware felt, that it lacked Wi-Fi, and that some features are locked behind a $100-a-year Hume Plus subscription plan. It works fine enough, but you can get results that are just as good with a cheaper device.
Garmin Index S2 for $191: Five years after its release, the Index S2 is still Garmin’s current model, a surprise for a company otherwise obsessed with fitness. It’s still noteworthy for its lovely color display, which walks you through its six body metrics (for up to 16 users) with each weigh-in. The display also provides your weight trend over time in graphical form and can even display the weather. The scale connects directly to Wi-Fi and Garmin’s cloud-based storage system, so you don’t need a phone nearby to track your progress, as with Bluetooth-only scales. A phone running the Garmin Connect app (Android, iOS) is handy, so you can keep track of everything over time. Unfortunately, as health apps go, Connect is a bit of a bear, so expect a learning curve—especially if you want to make changes to the way the scale works. You can turn its various LCD-screen widgets on or off in the app, but finding everything can be difficult due to the daunting scope of the Garmin ecosystem. The color screen is nice at first, but ultimately adds little to the package.
Omron BCM-500 for $92: With its large LCD panel, quartet of onboard buttons, and oversize silver electrodes, the Omron BCM-500 is an eye-catching masterwork of brutalist design. If your bathroom is decked out in concrete and wrought iron, this scale will fit right in. The Bluetooth unit syncs with Omron’s HeartAdvisor app (Android, iOS), but it provides all six of its body metrics directly on the scale, cycling through them with each weigh-in (for up to four users). It can be difficult to read the label for each of the data points, in part because the LCD isn’t backlit, but the app is somewhat easier to follow, offering front-page graphs of weight, skeletal muscle, and body fat. On the other hand, the presentation is rather clinical, and the app is surprisingly slow to sync. For a scale without a Wi-Fi connection, it’s rather expensive too.

To Start Doing What You Want to Do, First Do Less
This applies not just to things you have to do, but also things you think you want to do. Maybe you think you should learn Spanish, but you haven’t done anything to actually learn Spanish. Admitting that you aren’t actually committed to the idea enough to do the work of learning Spanish can help close that loop. Letting go of that feeling that you should learn Spanish just might be the thing that frees up your mind enough that you decide to take up paddleboarding on a whim. The point is that the new year isn’t just a time for starting something new. It’s a time to let go of the things from that past that are no longer serving you.
In many ways this is the antidote to that ever-so-popular slogan “Just do it.” Just do it implies that you shouldn’t think about it, instead of deciding what you really want to do or should do. Maybe spend some time remembering why you wanted to do it in the first place, and if those reasons no longer resonate with you, just don’t do it.
If you like this idea, I highly recommend getting Allen’s book. It goes into much more detail on this idea and has some practical advice on letting go. You can still keep track of those things, in case you do decide, years from now, when you’re paddleboarding through the Sea of Cortez, that now you really do want to learn Spanish and are willing to do the work.
Remember to Live
I will confess, my enthusiasm for Getting Things Done has waned over the years. Not because the system doesn’t work, but because I have found my life more dramatically improved by doing less, not more. It’s not that I’ve stopped getting things done. It’s that I’ve found many of the things I felt like I should do were not really my idea; they were ideas I’d internalized from other places. I didn’t really want to do them, so I didn’t, then I felt guilty about it.
While everything I’ve written above remains good advice for starting a healthy habit and keeping it going, it’s worth spending some time and making sure you know why you want to do what you’re doing. I have been rereading Bertrand Russell’s In Praise of Idleness, and this line jumped out at me: “The modern man thinks that everything ought to be done for the sake of something else, and never for its own sake.”

Oh No! A Free Scale That Tells Me My Stress Levels and Body Fat
I will admit to being afraid of scales—the kind that weigh you, not the ones on a snake. And so my first reaction to the idea I’d be getting a free body-scanning scale with a Factor prepared meal kit subscription was something akin to “Oh no!”
It’s always bad or shameful news, I figured, and maybe nothing I don’t already know. Though, as it turned out, I was wrong on both points.
Factor is, of course, the prepared meal brand from meal kit giant HelloFresh, which I’ve tested while reviewing dozens of meal kits this past year. Think delivery TV dinners, but actually fresh and never frozen. Factor meals are meant to be microwaved, but I found when I reviewed Factor last year that the meals actually tasted much better if you air-fry them (ideally using a Ninja Crispi, the best reheating device I know).
Especially, Factor excels at the low-carb and protein-rich diet that has become equally fashionable among people who want to lose weight and people who like to lift it. Hence, this scale. Factor would like you to be able to track your progress in gaining muscle mass, losing fat, or both. And then presumably keep using Factor to make your fitness or wellness goals.
While your first week of Factor comes at a discount right now, regular-price meals will be $14 to $15 a serving, plus $11 shipping per box. That’s less than most restaurant delivery, but certainly more than if you were whipping up these meals yourself.
If you subscribe between now and the end of March, the third Factor meal box will come with a free Withings Body Comp scale, which generally retails north of $200. The Withings doesn’t just weigh you. It scans your proportions of fat and bone and muscle, and indirectly measures stress levels and the elasticity of your blood vessels. It is, in fact, WIRED’s favorite smart scale, something like a fitness watch for your feet.
Anyway, to get the deal, use the code CONWITHINGS on Factor’s website, or follow the promo code link below.
Is It My Body
The scale that comes with the Factor subscription is about as fancy as it gets: a $200 Body Comp scale from high-tech fitness monitoring company Withings. The scale uses bioelectrical impedance analysis and some other proprietary methods in order to measure not just your weight but your body fat percentage, your lean muscle mass, your visceral fat, and your bone and water mass, your pulse rate, and even the stiffness of your arteries.
To get all this information, all you really need to do is stand on the scale for a few minutes. The scale will recognize you based on your weight (you’ll need to be accurate in describing yourself when you set up your profile for this to work), and then cycle through a series of measurements before giving you a cheery weather report for the day.
Your electrodermal activity—the “skin response via sweat gland stimulation in your feet”—provides a gauge of stress, or at least excitation. The Withings also purports to measure your arterial age, or stiffness, via the velocity of your blood with each heartbeat. This sounds esoteric, but it has some scientific backing.
Note that many physicians caution against taking indirect measurements of body composition as gospel. Other physicians counter that previous “gold standard” measurements aren’t perfectly accurate, either. It’s a big ol’ debate. For myself, I tend to take smart-scale measurements as a convenient way to track progress, and also a good home indicator for when there’s a problem that may require attention from a physician.
And so of course, I was petrified. So much bad news to get all at once! I figured.
