Solar Farming in Africa: Green Electricity Powered by the Sun

In the fourth installment of iq2 Shorts series, Professor Michael Düren of DESERTEC argues that we can harness the African desert sun to power the world. The animation is adapted from their Switched On evening ‘Energy Game Changers’ from March 2012.

Thanks for sharing this– love the animated approach! Our site did a story on this project when it was first announced, and personally I think it’s brilliant. It seems somehow ridiculous that we as humans have not yet figured out that harnessing solar and wind energy naturally should be a lot better for our planet than nuclear energy. Hopefully Desertec will make strides towards leading us into a new clean energy era.

I have to wonder if this isn’t too good to be true. There is lots of sun in the Sahara. That’s good. The sun doesn’t shine at night. That’s given. So the technology (parabolic mirrors, I suppose) collects heat, which operates a boiler.

Hmm. There’s not much water in the Sahara, or by definition any other desert. What’s the environmental cost of building a large solar installation that uses a boiler to turn a turbine? Where will the water come from? Or will the boiler boil something else?

One more thing. The al-Queda-type thugs in Mali and wherever else they turn up won’t exactly cooperate with the development of something that will benefit Europe, or even foster peace in northern Africa.

I’d like to see something like this work. I need reassurance that it really can, both environmentally and geopolitically.
