Renewables Reached Nearly 50% of Global Electricity Capacity Last Year (theregister.com) 114

Renewables made up nearly half of global installed electricity capacity by the end of 2025, "accounting for 85.6% of global capacity expansion," reports the Register, citing the International Renewable Energy Agency's (IRENA) 2026 Renewable Capacity Statistics report. "Per IRENA's data, that aforementioned 85.6 percent share of new power capacity additions was actually a decrease from 2024, when renewables were about 92 percent of global capacity additions. Yes, the share of total installed power capacity in 2025 rose again, but non-renewable capacity additions also rebounded sharply last year." From the report: Solar, in turn, was the dominant renewable technology, accounting for nearly three-quarters of last year's renewable capacity additions. Those additions totaled 692 GW in 2025, lifting installed renewable capacity by a record 15.5 percent year over year, IRENA noted. By the end of last year, renewables accounted for 49.4 percent of global installed electricity capacity, while variable renewable sources such as solar and wind represented roughly 35 percent of total capacity. For reference, it was only in 2023 that renewable energy sources crossed the threshold of generating 30 percent of the world's electricity.

    I would expect it to be even more. In Germany I think every euro spent on renewables makes us less dependent on the strait of hormuz and other fossil nighmares.

          It's called a battery and you will probably have to recharge, with a diesel you can manage on one tank but hey, that; s not renewable.
          So why complain you need to recharge, electricity is cheaper, especially since Trump closed the Strait of Hormuz.
          • "electricity is cheaper"? That depends on where you're doing it. In Oregon, I believe my RAV4 plugin costs 3 times as much to fuel on gasoline than on plugging it in at home. There are parts of California where the price of electricity is so high that gasoline is cheaper, despite the ridiculously high cost of gasoline. And of course gas taxes figure prominently into the "is gas or electricity cheaper?" calculation. I believe electricity is currently cheaper in most places now.

        • by tragedy ( 27079 )

          Warsaw to Berlin is about a 5.5 hour drive. It also seems to be cherry picked as a distance that is just slightly beyond the range of an average EV, but just in range of an average ICE. The average EV can make the trip with one charging stop from 20% to 80%. The average time for that charge is about half an hour (though some EVs can do it about a quarter of an hour). So, that makes the 5.5 hour drive a 6 hour one. That's about a 9% increase in travel time or less. Not showstopping for most people.

          The distance is 572km ... so basically every electric car and every gasoline/diesel car should make it.

          However: if you mean with Tank a Panzer ... then one tank would not get you very far. As Poland and Germany is now allied ... I assume, yes you can go with one Tank with renewables from Berlin to Warsaw.

The pretty much same thing applies to any wannabe autarkist nation that doesn't happen to sit on a massive oil field too.

      Don't get me wrong, I'd LOVE to have a small nuclear reactor in my basement. But the solar panels and a battery are lot more plausible and pretty much no matter what goes down, gonna remain more sourceable than nuclear fuel or steady supply of oil.

      If the biosphere on this dumbass planet survives, it'll be through the extreme luck that once we chipped at battery and solar panel manufacturing for long enough, fossil fuels turned out to be simply not even that convenient in comparison.

        Yep, even if you couldn't get lithium batteries, at least you could still make inferior lead-acid ones. You might need a battery room to accommodate the homebuilt kind, but they'd still be feasible.

    As far as I understand, a wind turbine capacity is just the maximum the generator can deliver, requiring typical 15m/s wind. Over that you rotate the blades to avoid too high loads. But most often the wind is much lower (and power is the v^3), the average production is much lower.
    • I came here to comment along those lines.. what do they consider 'capacity'? Is it a fictional amount that would occur if maximum wind and maximum sun fell onto all turbines and panels, or is it an amount that they realistically generate on average?

      • by quenda ( 644621 )

        "Capacity" is extremely important for generating headlines. Less so for generating electricity.

        But the numbers for actual generation of electricity from renewables are still impressive. Globally is is around 34%. Not bad!
        I'll take a real 34% over a hyped 50% any day. The growth in solar over the last ten years has been amazing. And now be are building the batteries needed to push the numbers higher.

        • Fair enough, 34% globally is a good number. But on the other hand, that's what it is today, not in a world with mainstream EVs and more datacenters built and private corporations buying entire nuclear power plants. I just wish we could be free of flashy headlines and just get real data. I find that I have formed a suspicion of anyone promoting electric because so often there is a reality distortion filter with them.

            not in a world with mainstream EVs

            I'm not particularly worried about it. Our ability to build and deploy Wind and PV (measured in GW capacity) is much larger than our ability to build and deploy EV batteries (measured in GWh capacity). China is deploying around 1 GW of new PV per day within its own borders, and exporting a huge amount to other countries. Meanwhile, the estimates of China's battery manufacturing capacity (EVs, stationary, portables) is on the order of 10 GWh/day.

            As you rightly point out, capacity (GW peak) is not the s

          • Just a side note, the refining of oil to gas takes about as much electricity per distance driven as EV. So no, if the whole world moves to EV we're not going to have a terrible energy problem.
            • Generally oil refineries are on industrial power grids, not residential grids that aren't designed for the power delivery.

              • True, but that reduces the problem to the delivery and not the generation, in times where the former is easier than the latter. Parent comment seemed to claim that the energy budget would not allow a full transition to EV.
                • When I say infrastructure I mean generation AND delivery. If my neighborhood needs a bigger infrastructure because now 100 people need to charge at night then I will be paying for that. Now electricity will be approaching the price of gas but I still use it to heat my home.

It ranges from about 90% for nuclear down to only about 5% for natural gas combustion turbines. Renewables are at various places in between: around 20% for solar, 30% for wind, 70% for geothermal.

    Without oil, natgas and coal we live in the 18th century.

    • You won't see wars fought over solar panels or wind turbines because "anyone" (industrialized) can make them and it's not cost-effective to take them. Once the solar panels are installed somewhere, it's cheaper to make more than to go there, fight the people who have them, uninstall them, pack them up, ship them home, and then reinstall them. This goes many times over for the wind turbines.

      You don't see wars fought over coal plants or natural gas power plants or nuclear plants either, at most they are objectives but more commonly they're just targets in wars. And it's for the same reason, it's not worth it to try to ship them home.

      • Solar panels are the end product. If wars were to be fought, it would over the materials used to make solar panels.
