Renewable energy is reshaping the global economy—new report
World leaders gather for the UN climate summit (COP30) in Belém, Brazil, amid concerns about the slow progress in cutting global carbon emissions. Ten years into the historic Paris climate agreement, we are off track to meet its core objective, to keep global warming well below 2°C, relative to pre-industrial levels.
Yet there are glimmers of hope, and none more important than the astounding progress on renewable energy. Renewables are now so cheap that the clean energy transition is no longer an economic burden, it is a momentous opportunity.
Climate change campaigners tend to see renewables as an environmental imperative, an effective way of cutting emissions. They are that, of course. But they are also a powerful engine of investment, jobs and growth. They are reshaping the global economy. In my team’s new report, we lay out the evidence.
The first economic dividend of renewables is inclusion. Access to affordable energy remains a critical sustainable development goal, which shapes everything from education to health to women’s empowerment. Distributed renewables—from solar home systems to mini-grids—are our best chance yet of bringing affordable energy to all.
Across Africa, Asia and Latin America, renewable energy entrepreneurs are doing what national grids have struggled to do: reaching remote villages and replacing polluting diesel generators with clean, reliable power.
Because of its modularity, renewable electricity can be built out fast, expanded flexibly and maintained locally. Renewable energy firms are combining these technical advantages with new business models that make renewables more accessible (for example, through pay-as-you-go models) and keep benefits in the local community (for example, by offering energy services like cold storage, phone charging and water pumping, as well as electricity).
Investment, jobs and growth
If inclusion is the first dividend, investment is the second. Every dollar invested in renewables delivers more economic bang than a dollar spent on fossil fuels. The International Monetary Fund estimates that clean energy investments generate about 1.5 times their cost in economic activity, while fossil fuels yield less than one-for-one. Renewables do not just pay back; they pay forward through spending on supply chains and local wages.
The numbers are staggering. Between 2017 and 2022, climate finance flows into the 100 largest developing countries (excluding China) boosted their GDP by a combined US$1.2 trillion (£0.9 trillion)—the equivalent of 2%–5% of GDP for most nations. In Brazil, the host of COP30, renewable investments raised GDP by US$128 billion over those six years, according to our report.
Climate finance flows are still insufficient. To increase them, we need more concessional funding, more risk guarantees and more partnerships between governments, investors and local communities.
In the Dominican Republic, a blend of policy reform, clear incentives and blended finance has helped the country mobilize over US$6.5 billion in clean energy investment and double its renewables capacity in just three years.
The energy transition is often painted as a jobs killer, but the evidence says otherwise. Intergovernmental organizations project that there will be 43 million clean energy jobs by 2050, far outstripping those lost in fossil fuels.
For our report, we took a closer look at the jobs market in South Africa. For 12 months we collected data from job adverts and found a striking fact: clean energy jobs pay 16% more on average than all other advertised roles. For the most part the higher wages reflect the fact that clean energy jobs are high-skilled jobs, which require experience, training and problem-solving skills.
The high skills requirements are a challenge as well as a boon. Taking full advantage of the clean jobs revolution will require proactive skills development, both in the classroom and on the job. But for the young labor forces of many developing countries, the message is clear: renewables are not just a climate strategy, they are a job opportunity.
Perhaps the most underappreciated economic benefit of renewables concerns productivity. Cheap, efficient energy is the lifeblood of industrial growth. Renewable energy is now much cheaper than fossil fuels, particularly when factoring in what is lost when turning energy (say, car fuel) into usable services (propulsion).
We calculated that with a rapid conversion to renewables, energy-sector productivity could double by 2050, compared to both current levels and a fossil fuel future. Since energy is such a ubiquitous input to all other economic activities, this has significant economy-wide benefits. For some developing countries, the GDP boost could be as high as 9%–12%—simply from having more efficient energy services.
These productivity gains are not evenly distributed. For once, it could be developing countries that benefit most. Industrialized countries grew rich on the back of cheap and abundant energy. In a low-carbon economy, it will be sun-rich developing countries that have the cheapest, most abundant sources of energy. This critical shift in comparative advantage could finally help to narrow the global prosperity gap.
At COP30, leaders are debating climate targets, finance mechanisms and transition timelines. But they should also recognize this deeper reality: renewables are not a drag on growth but its new engine. In a world anxious about growth and prosperity, the clean energy transition is an economic strategy as much as an environmental one.
The challenge, as our report reminds us, is to share these gains equitably. Without fair benefit-sharing the transition risks repeating the inequities of the fossil fuel era. But get it right, and renewables can power not just cleaner economies, but fairer ones.

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.
