Not perhaps a week for good news—not with former U.S. President Donald Trump trying to initiate a pogrom in Ohio (and the Secret Service protecting him from a crazy right-winger). Not with insane floods across Central Europe where the blue Danube is now a raging brown monster, or in the Lake Chad region where hundreds are dead.
But there’s something else going on behind the scenes—silently. And it’s happening in places where people need it most.
Solar panels have, over the last months, suddenly gotten so cheap that they’re now appearing in massive numbers across much of the developing world. Without waiting for what are often moribund utilities to do the job, business and home owners are getting on with electrifying their lives, and doing it cleanly.
This won’t just transform the climate, it will transform lives.
How do we know? Basically by good sleuthing. The first account I saw came from Azeem Azhar and Nathan Warren. They were looking at Pakistan, where power prices in the wake of Russian President Vladimir Putin’s Ukraine invasion have soared so dramatically that sales of electricity have gone down 10% in the last two years. That should cripple a country—”yet somehow it’s economy grew by 2% anyway.” Again, that should have been impossible: if there’s a truism, especially in the developing world, it’s that growth in energy use is tied to growth in economies. So what was happening? Basically, Pakistanis were buying huge quantities of very cheap Chinese solar panels and putting them up themselves. Pakistan, they reported, “has become the third-largest importer of Chinese solar modules, acquiring a staggering 13 gigawatts in the first half of this year alone.” This is particularly astonishing because the country’s entire official electricity generating capacity is only 46 GW. In other words:
in just six months, Pakistan imported solar capacity equivalent to 30% of its total electricity generation capacity—an absolutely staggering amount.
Energy analyst Dave Jones has gone to great lengths to track this spread on Google maps, finding building after building across the country with big new solar arrays on the roof. For middle-class Pakistanis, they can pay off the investment in a few years selling back power to the grid; in poor areas, things like tube wells for irrigation are now increasingly run on solar. This means not just a decline in natural gas use for centralized generation; it also means many noisy, dirty, and expensive diesel generators that used to provide backup power are being turned off. The great solar analyst Jenny Chase at BNEF has found much the same thing. As Azhar and Warren point out:
by the end of the year, Pakistan’s distributed solar system could be nearing half the capacity of its entire grid! This isn’t just growth; it’s a silent revolution in energy production.
Were it just Pakistan, it would be a wonderful story but perhaps not definitive. But I had a long talk last week with Joel Nana, an analyst at Sustainable Energy Africa in Capetown who told a very similar story. He’s been leading a project to help countries across the continent deal with the increase in distributed generation, and he reports something similar happening in country after country—Zimbabwe, Eswatini, Lesotho, Madagascar, on and on.
“In Namibia we uncovered they have about 70 megawatts of distributed generation—that’s rooftop solar pv that’s about 11% of Namibia’s installed capacity. Eswatini, it’s an old figure, but they’re already at 30 megawatts and it’s a very small country. That’s about 15% of Eswatini’s installed capacity. South Africa is the biggest market, and it has five gigawatts of distributed solar—about 9% of South Africa’s installed capacity.”
“You will not see these numbers anywhere,” he said. “They’re not reported in national plans, not anywhere in continental statistics. No one knows about them. It’s only when you speak to the utilities,” and even they know mostly about the larger installations—there are doubtless far more hut-scale systems across Africa. People are driven by the high cost of electricity, but also by its unreliability—in much of the continent “load-shedding” is endemic, with diesel generators roaring on to compensate, at least at businesses solvent enough to afford it. But diesel fuel is expensive, and generators are hard to maintain. PV is “a no-brainer for most businesses if not all,” he said. “The prices just make sense. The African market is a huge market for some of the Chinese manufacturers, so we have availability—huge availability. The market is flooded with panels from China.”
All this, he points out, is happening without any help from governments, and except for South Africa without financing from banks, who haven’t yet learned how to evaluate the credit risk. The continent needs more trained solar installers, and coordinated standards. On the other hand, many nations probably won’t need the big and expensive increases in bulk electric supply they’ve been predicting. And Nana and his colleagues are working hard to figure out how to make the most of this—how to turn solar pv into real economic assets for entire communities, through practices like net metering.
This is extraordinary news, in large part because it’s happening in places where people most need power—I’ve spent a fair amount of time in Africa looking at communities getting their very first power thanks to the sun. (And I’m headed back as soon as the election is over, so watch this space for more). This won’t just transform the climate, it will transform lives.
It comes on top of more visible good news—the IEA said this weak that oil demand around the world is softening because of “surging” sales of electric vehicles. In China, demand for gasoline will peak this year or next and then decline sharply. Britain, where the coal era was born, will close it’s last coal-fired power plant at the end of this month, while California—arguably Earth’s most modern economy—has managed to weather its worst heatwaves ever without blackouts this simmer thanks to ever-growing batteries of… batteries. (The state’s one big recent blackout came when a gas-fired plant went down in Pasadena). Hey, photovoltaics are getting so sensitive that they’re starting to be useful indoors, where they could replace small disposable batteries.
But nothing beats the idea that solar panels are suddenly sprouting, as if by magic, precisely where they’re needed most. If we can get there fast enough—before we’re overwhelmed by droughts and floods—then a sunny new world is entirely possible.
