I would argue that we are already seriously building more and more solar and wind power, along with research into better battery storage. Even if we solve the current climate crisis with solar and wind, we may still be able to do even better with fusion in 50 years. Fusion would be very energy dense, requiring a lot less resources and land than solar or wind, and has the potential for even cheaper and less environmentally-destructive energy than current renewable resources.
