...AND CHEAPER...:

Morocco poised to become a solar superpower with launch of desert mega-project : World's largest concentrated solar power plant, powered by the Saharan sun, set to help renewables provide almost half the country's energy by 2020 (Arthur Neslen, 26 October 2015, The Guardian)


When the full complex is complete, it will be the largest concentrated solar power (CSP) plant in the world , and the first phase, called Noor 1, will go live next month. The mirror technology it uses is less widespread and more expensive than the photovoltaic panels that are now familiar on roofs the world over, but it will have the advantage of being able to continue producing power even after the sun goes down.

The potential for solar power from the desert has been known for decades. In the days after the Chernobyl nuclear accident in 1986 the German particle physicist Gerhard Knies, calculated that the world's deserts receive enough energy in a few hours to provide for humanity's power needs for a whole year. The challenge though, has been capturing that energy and transporting it to the population centres where it is required.

As engineers put the finishing touches to Noor 1, its 500,000 crescent-shaped solar mirrors glitter across the desert skyline. The 800 rows follow the sun as it tracks across the heavens, whirring quietly every few minutes as their shadows slip further east.


When they are finished, the four plants at Ouarzazate will occupy a space as big as Morocco's capital city, Rabat, and generate 580MW of electricity, enough to power a million homes. Noor 1 itself has a generating capacity of 160MW.
