Currently 1.2 billion people in the world do not have access to electricity, and there are plans to try to get them on the grid. The numbers you start dealing with become so large that they are difficult to comprehend,” Professor Jones says.

“To even come close to achieving the goals of the Paris Agreement, 50% of our energy will need to come from renewable sources by 2028, and today it is only 9%, including hydropower. For a world that wants to fight climate change, the numbers just don’t add up to do it.”»
