On the face of it, no, it doesn't sound revolutionary. "Just switch to renewables" is something I've been hearing for 20 years and I never believed it could work until I read this book.
The book is quite thorough in laying out all the challenges (eg, handling variable production from renewables, how to get buy-in from existing fossil fuel stakeholders, how to rearchitect the grid from hub-and-spoke to something more like the internet, how to finance the massive upfront cost in a way that will actually save money, etc) and presents realistic solutions for each.
Please don't take my word for it, just pick up a copy and read it.
