Well it depends on where you need it, costs of extraction etc.
You can cover the sahara with whatever plants you want but the upkeep of a farm made of sand over 3.5 million square miles would be pretty immense.
Where a sealed bucket of shit with a gas valve is pretty easy to get going.

Possible retard question:
Why don't 'they' cover areas like the Sahara in solar panels?

It's fucking hot and sunny, no cunt lives there and it's useless for agriculture. I must be missing something obvious here.

maintenance
i did read that if 1% of the world's deserts were solar panelled we'd have more than enough energy for the whole world

Why not employ the starving Africans to do the maintenance, then?
All they seem to do is sit around swatting flies off their kids. It would give them something to do instead of waiting around for Oxfam to bring them some second-hand underpants.

can you imagine the heat they would have to withstand? the kit would be failing all the time
and the temperature would be unbearable for most people, costs would be gigantic

plus i think we're underestimating the size of 1% of the world's deserts, thats probably shitloads of thousands of square miles

They're used to it. I've seen them on Blue Peter.
They fucking love that shit.

Fuck the Sahara
I'd be happy if we simply covered Chelmsford in solar panels and rendered it uninhabitable.
