Bill Gates once again shunned solar power from his vision for energy access in Africa in his talk at the University of Pretoria in South Africa on Sunday, where he argued that whilst “cheap, clean energy” is what Africa needs, solar does not fit the bill.
During the delivery of his Nelson Mandela Annual Lecture, the Microsoft founder and philanthropist identified that Africa, like the rest of the world, is in need of a “breakthrough energy miracle that provides cheap, clean energy for everyone.”
Africa is more dependent on such a phenomenon than other continents, because seven in ten Africans still lack power at present, while more than 500 million Africans still will not have electricity by 2040.
This is not the first time Gates has taken a less than welcoming stance to solar power. In February, during an interview with a news outlet, he echoed a similar thought. “When I say ‘an energy miracle’,” he said, “I mean that there will be some form of energy whose 24-hour cost really is competitive with hydrocarbons given, say, 20 years of learning curve.
“You invent it, then you look at how much its costs go down over the next 20 years, that it really beats hydrocarbons.
“You might say, well, aren’t people saying that about wind and solar today? Not really. Only in the super-narrow sense that the capital costs per output, when the wind is blowing, is slightly lower.”
In fact, Gates has been advocating anti-solar sentiment for a while. In 2014, he blogged about energy poverty, arguing for outdated fossil fuel solutions to tackle the electricity deficit in underdeveloped economies, characterising energy poverty as a climate issue.
Solar is ‘not enough’
In the speech on Sunday, the software entrepreneur recommended increased investment in renewables, namely hydropower and geothermal. He went on to argue that recently launched solar power initiatives have not been enough:
“There has been a lot of experimentation with small-scale renewable energy, including micro solar,” he said. “This approach can provide individuals with some electricity for basic purposes, but it’s not going to be the solution for the continent as a whole.”
