The problem is scientific not just technology optimization though. Wind and solar just can't deliver, they are linear solutions to exponential problems. They do around 1% today only expected to be 3-4% in 2040 and that's with the current energy need which will increase significantly in as more people become middle class. So we need something groundbreaking with high energy density and scalability and which is cheap.
