The current science community and green advocates have not yet gotten to this point of understanding and are still pushing wind and solar as viable solutions. They believe we just have to re engineer the grid, invent cost effective storage and be willing to pay a lot more for energy. This is political suicide as the costs and limits become apparent.
Bill Gates vision is more complete in that it recognizes the need to attempt many unorthodox “miracle” solutions in order to find one that succeeds. Intuitively his investment and promotion of Terrapower also show that investment needs to target companies that are attempting a complete solution, not science, basic technologies or government R&D.
