If a mere 1% of the Sahara Desert were covered in solar panels, enough energy would be generated to power the entire world. That's a lot of potential energy! So it only makes sense that just such a solar field is being built.
Within the next five years, a massive solar farm will begin construction, one that will continue being expanded over the coming decades. At first, it will provide a smaller proportion of energy to European nations, but as methods of transmitting so much energy are developed and the fields are expanded, that proportion should grow.
With the project slated to go until 2050, the potential is huge to get the entire continent powered by renewable energy in our lifetimes. Exciting stuff!
