Renewable Energy is Surging in Africa (apnews.com) 140

Almost a fifth of the earth's population lives in Africa. And Africa's next generation of power projects "is increasingly being built around solar and wind power and battery storage," reports the Associated Press, "as governments and investors shift away from coal and large hydropower dams in search of cheaper, faster and more reliable electricity." The shift is visible in a $1.5 billion energy agreement between China and Zambia announced in early May that includes three separate 300-megawatt projects spanning solar, wind and coal-fired power. While the inclusion of coal underscores the continent's continuing need for stable baseload electricity, African countries facing rising fuel import bills as a result of the Iran war, unreliable grids and growing industrial demand are increasingly turning to renewable energy projects that can be deployed faster and more cheaply than traditional plants.

Of the 322 energy projects announced across Africa in 2025, 173 were solar projects, followed by hydropower at 46, wind at 34, gas at 22 and hybrid energy projects at 14, according to the energy research firm Electron Intelligence... Utility-scale solar power costs have dropped by nearly 90% globally since 2010, while onshore wind costs have fallen around 70%, making renewables the cheapest source of new electricity generation in many African markets...

Much of the growth is through distributed solar and battery systems installed directly in mines, factories, telecom towers and homes. "Most official statistics still measure the energy transition the old way, by counting megawatts connected to national grids," [said Matt Tilleard, CEO of CrossBoundary Energy, which invests in renewable energy in Africa]. "But solar and batteries don't need central utilities." Data from the Africa Solar Industry Association shows 23.4 gigawatts of operational solar projects had been tracked across Africa by the end of 2025. But Chinese export figures indicate 58.1 gigawatts of solar panels have been shipped to African countries since 2017, suggesting solar adoption may be growing far faster than official figures capture.

Investor Tilleard says "Renewable energy is now unequivocally the fastest, cheapest, and most bankable way to connect people, companies and economies to the megawatts they need to grow."

And the article also includes this quote from Mugwe Manga, climate finance lead at FSD Kenya. "Africa is not on the periphery of the global energy transition, it is sitting at its center. The continent holds the world's best renewable resources, and the economics have now decisively turned in favor of clean energy."

    Both cellphones and renewables were entering a region that had far less legacy infrastructure. Plus renewables can operate locally much more easily.

      Also Africa has a heck of a lot of sun in patterns that are more consistent all year round. Close to the equator you may get less sun in the day but you don't get a 4x difference between the peak summer production and minimum winter production as we do here.

      More consistent output means it's easier to plan around, and not having winters at 40 below zero means even if the power is out for a while you're probably not going to die.

      Lastly, of course, with local power production there aren't thousands of miles of copper cables and tall metal pylons to cut up and steal.

      That's actually the area of my interest. This would seem to be a natural situation for local power grids without the need for investment in long distance high voltage transmission. There can be an advantage to skipping over the earlier technologies if you pick the right stuff. The problem is knowing what "right" means because that's largely dependent on the "maturity" of the technologies in question.

      But where is the angle to go for the funny? I'm not really seeing any good ones for this story. Something about the AI advice to investors in Africa? (Maybe something about what the AI said when it found Dr Livingstone?)

      • The key to 'surfing the 2nd generation techs' is that you - defacto - can't be at the cutting edge. In fact you have to be a backward society *vastly* behind the curve to avoid having to have that legacy sunk-cost infrastructure.

        Nobody "skipped over" early tech, that implies agency. These are LEFT BEHIND economies. I don't think anyone chooses that as a strategy.

        So it's externally-developed tech that someone is selling them.

          Sure, but the point is that at least one silver lining on not having had reliable grid supplied electricity for every household is that it’s now possible for African countries to have a distribution-first approach to electricity that will be more equitable and cleaner than the alternative, and potentially much faster too.

          • Surely.
            The great example is phones - I'd love to see a data driven study on network quality/cost to users for cell phones in Africa. They largely skipped the whole "stringing wires all over the fucking place" step and jumped straight to cell phones. How has that worked for them compared to mature hardwire telephone systems in developed countries? Pros? Cons? Long term benefits/costs?

          One of the issues with integrating renewable energy into the North American grid is the 'sunk cost' of all that cruft of installed hardware. Another is the accounting/tax requirements, and yet another is the organizational structures of the US energy system. Transformers are expected to last 20+ years for example, no executive is going to forgo their quarterly bonus by replacing "dumb" transformers that haven't been fully depreciated for "smart" ones that can deal with variable energy flows.

        I don't think most of it is planned, and that goes for Europe as well. Governments have some control, such as making rules around balcony solar or minimum allowances for rooftop solar to be connected to the grid, but for the most part it's been people installing it because of some personal decision they made (it's a great investment). The grid has been forced to change faster than the operator would have liked it to in many places, which is a good thing.

          In the main, although the Spanish national blackout just over a year ago suggests that maybe it changed too fast. (Hard to use a stronger word than "maybe" because my understanding is that the report on the causes didn't really say anything).

    • "Less legacy infrastructure" is a polite way of saying essentially no infrastructure at all, or infrastructure that's only functioning for an hour a day. When your choice is between solar hot water and no hot water, or solar power and no power, it's easy to choose the option that doesn't have "no" in it.

    1) Not tied to frequent fuel deliveries

    2) Does not require much that humans don't already need - sun and air. (Variability will affect your power storage needs)

    3) It can be deployed almost anywhere, and even be portable.

    The main issue is energy density - if you want to drive hundreds of kilometers a day, run your AC all summer and heat all winter, etc., you're going to need a lot of land dedicated to power collection.

    I imagine there are a lot of places in a continent like Africa where people might be happy to get by on what solar can give them in return for not having to worry about burning oil or anything else to get electricity.

    • Variability will affect your power storage needs

      Keep in mind that "variability" will included the African monsoon seasons (months varies across continent).

      • Start with a ducted horizontal wind turbine. If you imagine a bunch of salad bowls stacked with spacers and you get the idea of what it would look like from the outside.

        The ducts collect air from any direction and drive it down, through the turbine, and out the bottom. Water doesn't turn corners quiet as easily as air, so you can use the ducts to separate out the majority of liquid and drain it away from your turbine.

        Then you and an armored shell of horizontal bands that can be moved up and down to reduce

          There's your monsoon-resistant wind turbine.

          And now initial cost and ongoing maintenance costs are scaled by what factors? Assuming it really is that simple of course.

          • The additional cost over a normal horizontal ducted turbine is, of course, the new shell and the actuator it requires.

              I've not really see ducted turbines at all on local projects nor proposals.

              When I google to see if I have missed something I find:

              "Ducted (or shrouded) wind turbines are not common in major proposed wind projects. The commercial and utility-scale wind industry is dominated by conventional, open three-blade Horizontal Axis Wind Turbines (HAWTs).While ducted turbines offer theoretical efficiency boosts by accelerating wind through the rotor, they are rarely used in large-scale applications for several k

      There's actually only one reason.

      They can't get credit for anything else.

      African nations are exceptionally capital poor. Basically all projects are funded by foreign investment banks.

      Last decade and a half was significant reduction on any power plant infrastructure loans that were for anything other than solar and wind, of which time after 2015 (Paris Agreement) was almost a total ban. This hit even the one exception in Africa: SA, and is one of the reasons for their constant blackouts. Though as is the cas

  • When your power plants are non-existent or unreliable, a power source you can purchase and maintain becomes a wonderful choice.

    Similarly, people living in a homestead situation do the same thing. Alaska cabins almost all have solar and often have wind or a water turbine.

    The estimate is that about 300m people in Africa now have access to more (and more reliable) electricity thanks to the adoption of solar home systems (typically a panel, integrated battery, LED, phone charge, and outlet for a small appliance). Community power systems are providing transport as well. It’s going to be transformative. As I’ve mentioned here before, it means kids can do their homework at night, food stays fresh for longer thanks to being able to run a fridge, and respiratory health improves without kerosene and generators running. People pay with microloans and the costs of paying off the loans is a heckuva lot lower than paying for fuel, and doesn’t have volatility either.

    • by PPH ( 736903 )

      Yep. But what TFS summary seems to be talking about is investment in utility grade renewable generation. Which will help out the big cities and industrial sites. But they won't do squat for the villages miles off the end of the distribution grid.

      They do acknowledge that most of the growth is in distributed systems. And that this growth is difficult to measure using the national grid demand. But it looks like they could use more home and village systems as well.

      • by shilly ( 142940 )

        They need more of everything! More SHS, more community systems, more industrial scale systems, etc.

        But one thing this article doesn’t really capture is how dramatic the surge has been in the last few weeks, sparked by Trump & Hormuz. It’s at least double the monthly import rate of last year.

        So the pace of change is increasing

The other line moves faster.
