Renewables Overtake Coal As World's Biggest Source of Electricity (bbc.com) 70

AmiMoJo shares a report from the BBC: Renewable energy overtook coal as the world's leading source of electricity in the first half of this year -- a historic first, according to new data from the global energy think tank Ember. Electricity demand is growing around the world but the growth in solar and wind was so strong it met 100% of the extra electricity demand, even helping drive a slight decline in coal and gas use. However, Ember says the headlines mask a mixed global picture.

Developing countries, especially China, led the clean energy charge but richer nations including the US and EU relied more than before on planet-warming fossil fuels for electricity generation. This divide is likely to get more pronounced, according to a separate report from the International Energy Agency (IEA). It predicts renewables will grow much less strongly than forecast in the US as a result of the policies of President Donald Trump's administration. Coal, a major contributor to global warming, was still the world's largest individual source of energy generation in 2024, a position it has held for more than 50 years, according to the IEA.

        One thing that ChatGPT does well is fact-checking.

        Could someone living in Pennsylvania theoretically reduce property taxes by 15% by "upgrading" an oil furnace to a coal one?

        That’s a really interesting and creative idea — but no, someone living in Pennsylvania could not reduce their property taxes by 15% by switching from oil to coal heating.

        It then delves into minutae of Pennsylvanian tax [pa.gov] law [pa.gov], a furnace's impact on assessed property value, and how not even coal refuse (as opposed to ordinary coal) could affect property tax.

    • If the Ember trend (solar+wind continuing to meet new electricity demand and strongly displace fossil generation) continues and scales up aggressively only in electricity, then by 2100 we’d likely avoid ~0.2–0.35 C of warming relative to a BAU electricity case — a useful and meaningful improvement, but not a return to pre-industrial “normal.” To actually reverse global temperature to pre-industrial levels would require removing thousands of gigatonnes of CO (net) — a feat

    As I write this here in the UK sitting under a cloudy high pressure system with not much (inland) wind , 47% of our electricity is being generated by gas, 21% wind and 13% solar. Good, but not great , and there are always planning battles over siting of new wind and solar farms. Wind can be put in the sea (making it more vulnerable to russian sabotage but thats another discussion) but solar can't so we're probably not far off the install limit of the latter unless the government starts compulsory purchasing land for it.

    • The problem with solar is not the land - they keep finding dual use projects where they add solar to something else (canals, farms, parking lots.

      Instead the problem is that solar gives out at the same time. Once you have about 25% solar, you usually do not want more. You are going to need at least 30% of your power to work at night during very hot summers. Similar problem with winter. Once you build the power supply for the night, it's going to stop working during the day, so you really only need another

        Problem with your calculation is that it is already outdated. Germany right now is at 57.4% renewables for the whole year of 2025, and not just a good month. The worst month in Germany in 2024 was November with only 45.1% Renewables, but two month, February and April (yes! those two!) came in at more than 60% Renewables. The whole of 2024 finished at 55.8% Renewables for electricity production.

        This is just drivel. There’s no problem with overbuilding, and behind-the-meter solar savings will continue to destroy demand and extend the duck curve everywhere, especially as battery storage costs continue to drop. The main rate limiting step will probably be the challenge of the split incentives in commercial property between landlord (typically would have to pay for installing solar) and tenant (typically pays electricity bills). There are ways round it but they’re hard, and PE houses rare

      • Solar is so intermittent that you can't depend on it even during the day. That is, if you build solar so that it will give you that 75% at say 10 AM on a slightly cloudy winter day, then at 2 PM on a sunny summer day it will give you 300% of what you need.

        This is actually good for two reasons. Firstly, most renewable energy sources can be trivially and immediately switched off. When you are generating 300% with a nuclear power station, that's a disaster because you have to send that somewhere, so you end up paying people massive quantities of money to use the power that you have nothing you can do with just so that, half an hour later, you can deliver a brief peak. Same happens with solar? Just instantly turn off 75% of your panels and problem solved at no c

      Have a look at this wind speed map: https://zoom.earth/maps/wind-s... [zoom.earth]

      There is still a massive amount of on- and off-shore wind that we could harvest to replace that gas, much of it in the shallow waters of the North Sea.

      Last year, renewables were 35% of the UK's electricity production. We can easily and cheaply go much higher, which would help reduce bills as it displaces gas.

        I had a very interesting back-and-forth with ChatGPT about what it takes to replace the UK’s marginal gas pricing system. CfDs and PPAs were where it ended up. We had a little speculation about whether or not it would be cheaper to just buy out the older renewables generators from the marginal cost contracts, and concluded it probably would be.

    • The article talks about an elephant in the room here, which is that Europe and the UK are lagging because they just don't get enough sun to make solar work really well, and wind has not experienced anything like the 99.9% price reduction solar has since the 1970's.

On your second point, the political right has long since stopped giving a shit about what it bases its attacks on. When powerful men wang on about whales and birds to attack wind turbines, getting het up about handing them a free pass with an ambiguous phrase is a waste of energy.

        That's a gross exaggeration of the price decrease, and you also wouldn't expect wind to get cheaper as much as solar because we've been doing wind power for quite some centuries, but solar power for less than one.

      We brits aren't great at rooftop solar - we're getting better, but there's a long, long way to go. The square kilometres of untapped space are many, and if we get to using it, then the demand for grid electricity changes dramatically. Sure, cloudy days aren't as good as sunny ones, but I'll bet a lot of houses are just consuming "power vampires" right now, all of which could be powered by some solar, even on a cloudy day.

      Say nothing about our pretty terrible record on insulating our houses - if we do that, then the use of gas drops off a lot, and for those with electrical heating, things improve there too. The government is stuck in a rut of raising taxes until productivity improves, but if they ever get to doing some sort of incentives for domestic rooftop solar and (probably more importantly) thermal performance of our houses, then we could shift our whole grid and carbon discussion by quite a distance.

      But yes, our dependence on gas is far too great.

    So, for those of you into coal, why? There are NO jobs in it.
    FACT: in 1972, there were 778,000 coal miners. As of four or so years ago, there were 78,000 miners. Yes, a 90% reduction. Few deep mines, now it's mountaintop removal and HUGE machinery. And the remaining coal companies, in the ongoing war on coal MINERS, keep adding more automation.

      I know that when you write about a war on coal miners, you're only being rhetorical, but that wasn't always so.

That day's toll was 21 dead, mostly miners and their families, out of an estimated total of 69 to 199 people killed during the st
    • So, for those of you into coal, why?

      I don't think they're into coal so much as they're against market manipulation. Well, with the exception of West Virginia, where their entire economy is kind of built on coal.

      Also, the push against coal pairs with the push against natural gas, and there's way more reasons to be against that push.

  • Seriously, between a basic income story the other day, and now this, /. really needs a trigger warning icon for articles.
  • Seems to me that it's not just quantity supplied, but also cost per kWh that matters. It's often pointed out that fossil plants are still required on standby due to variability of "sustainable" power, which apparently is not necessarily sustainable over a 24 hour period. So, if the cost of idle plants is factored in, as it is into the actual cost of those kWhs, the greater amount supplied by "sustainable" may be a pyrrhic victory.

    • This is one of the reasons most renewable generation gets a much lower price per kWh than, say, gas. The exception is rooftop solar which is very expensive per kWh, but it still viable because it feeds in directly to the consumer, so it reduces expenditure at consumer rates, rather than selling at wholesale. Even with all this renewables still work out as cheaper, and given the falling cost of batteries and renewable generation that is likely to remain true.

    • by shilly ( 142940 )

      You’re not thinking about this correctly. We already *have* most of those plants that will be kept on standby, they’re just not running only on standby at present. So the capex is largely accounted for, and the idle costs are quite low because the main opex is (surprise!) fuel.
