Why don’t the poor African countries export solar generated electricity to make a few quid?

 

 

They would be exporting to neighbouring countries who have the same resource.  To export further they would need to pay countries in between to transmit that electricity.  That is both expensive and complicated.  Its a bit like saying why doesn't UK export rain water to Africa?

You can transmit electricity without involving your neighbours.

If the planet was surrounded by a rain water field then we could export rain water without pipes . It 'isn't though which is why the two examples are not comparable.

I don't know, why don't the poor African countries export solar generated electricity to make a few quid? 

Oh, sorry, thought I was in the joke thread.

Is it just down to cost?

Given the abundance of sunshine, space  and the need for electricity I thought there would be a business case for it. Maybe not.

I was just looking at some studies, to power the entire planet you’d need land equivalent to 3% of the US.

Isn’t it a bit like asking why poor people don’t invest their money in a successful business so they can have a regular income and not be poor anymore?

Not really.

Lack of profit most likely. 

There's a lot of money involved in destroying the planet .

I guess it’s down to the return.

I’m sure governments could raise the money through loans or private investment if the return was there. Are there other forces at play (like the oil / gas companies / states)?

Definitely.   The knowledge has been here a very long time but reliance on expensive and destructive energy is one of the glues that keeps humanity on the treadmill.

I'm sure they'll have had plenty of offers over the years, if it was to happen it would be one of these things where the Chinese build a motorway through the middle of the country and in return get to build a solar plant that they own, take all the profits from creates no jobs and has very little actual benefit to the host nation 

Maybe after hundreds of years of trading the rights to their minerals for a paltry return they've learned something...

Isn't the problem the vast distances it would have to travel to someone with the money to pay? There would be a lot of power loss over such large lengths of wire. 

Unless you had lorries with huge batteries used like oil tankers but then the cost stacks up.

I’m guessing the clue is in the question.

 

Cuz quid isn't their currency.

Losses transferring electricity are low, and the technology well established. 
Also, everyone needs electricity, near and far.

I’d assume transferring electricity vast distances is easier than gas and oil?

There will soon be room temperature superconductors. You could use them for batteries or wires.

Graphene might be an option soon for battery "tankers". Too expensive at the moment.

Projects that aim to do this have existed for some time. Most obviously, there is a high-voltage link from Morocco to Spain, and Morocco is a world leader in solar power for obvious reasons. There was at one time - I don't know if it's still planned, as such - a planned project called DESERTEC (https://en.wikipedia.org/wiki/Desertec), which essentially aimed to join up grids across north Africa and Europe, but there are quite a few challenges, including the threat to European energy security of relying too much on African energy, and tensions between north African countries (especially Morocco and Algeria). A nice-looking map of the DESERTEC dream from the Wiki article:

I emailed my MP the other day. 

I had quite a long reply last night from him.

Or was it him? Do they respond to their own emails or do they have a team that does it?
