Saudi Arabia has an unlikely solar star

SITTING ATOP a fifth of the world’s oil reserves, Saudi Arabia doesn’t spring to mind when you think about renewables. Muhammad bin Salman, its crown prince and de facto ruler, would like this to change. He wants half of Saudi electricity to come from wind and solar farms by 2030. Two-thirds of that capacity, or around 40 gigawatts (GW) will, if Prince Muhammad gets his wish (as he tends to do), be courtesy of one firm: ACWA Power.
