Observation: Global warming is a reality whose effects must be measured, but also question in resources. The planet does not enjoy the same climatic favors and yet we know the solar energy reserve!
Proposal: To go and get the solar energy where it is: to install a huge network of solar panels on stilts in the desert (in order to allow the fauna to circulate freely), to store this energy and to distribute it in the neighbouring regions (why not by arranging greenhouses and developing a reasoned agriculture)
