Amazing fact/quote: ‘in just six hours, the world’s deserts receive more energy from the sun than humankind consumes in a year.’
From Wikipedia (which gives the history of the associated project plus it’s pros and cons as well as the remarkable graphic above):
“The DESERTEC concept was originated with Dr Gerhard Knies, a German particle physicist and founder of the Trans-Mediterranean Renewable Energy Cooperation (TREC) network of researchers. In 1986, in the wake of the Chernobyl nuclear accident, he was searching for a potential alternative source of clean energy and arrived at the following remarkable conclusion: in just six hours, the world’s deserts receive more energy from the sun than humankind consumes in a year.
The DESERTEC concept was developed further by Trans-Mediterranean Renewable Energy Cooperation (TREC) – an international network of scientists, experts and politicians from the field of renewable energies – founded in 2003 by the Club of Rome and the National Energy Research Center Jordan. One of the most famous members was Prince Hassan bin Talal of Jordan. In 2009, TREC emerged to the non-profit DESERTEC Foundation.”
