Something that brings good news on all three would be a pretty good Christmas present for us all, wouldn’t it?

Well – in my speech on international development to party conference in September, I briefly touched on the question of using solar power from Africa’s deserts:

Let’s us be both ambitious and optimistic, particularly for sub-Saharan Africa. An area of great poverty and so often little progress. It is an area of huge potential for solar power. We have seen what wealth the oil era has brought many formerly poor areas of the world. Let’s aim for the era of green energy to spread those benefits more widely – and support the development of green energy.

At the moment, the sun beats down on these areas, and nearly all of the sun’s rays go to waste electricity-generation wise. Yet they hold a huge potential as a source of electricity to those countries and neighbours. It could be a case of win-win-win.

First, really large scale solar electricity production is not just renewable – no fears about the sun running out any time soon! – but brings benefits in the battle against global warming and the climate chaos that follows.

Second, just as the oil boom brought prosperity to millions in newly oil producing countries, a similar boom in green electricity production could bring prosperity to large parts of Africa, a continent so often blighted by poverty.

Third, bringing greater prosperity to parts of Africa and the Middle East will help undercut some of the forces driving armed conflict there. Reducing armed conflict, cutting the number of deaths and injuries, having fewer people flee their homes, cutting the number of refuges seeking refuge in grimy refugee camps or unwelcoming other countries: it’s all very much to be welcomed.

The possibility of securing this triple win is in the news at the moment thanks to the Desertec proposal recently presented to the European Parliament. It would see solar power stations being built in or near the southern shore of the Mediterranean. Power cables could then transport the electricity under the sea into electricity hungry Europe.

Current estimates are that this power would cost double electricity from other sources. At that price differential – there’s a problem, but given how technology can march on and drive down prices over time, I’m quite cheered by it ‘only’ being double at the moment.

You can find more details on the particular Desertec proposal on their website. Lots of food for thought – and optimism! – there.
