Sure, but solar won't be enough to power us forever, and doesn't scale like fusion eventually will. We will have energy needs orders of magnitudes more than we do right now within the next 20 years. I'm all for solar, but fusion will be necessary just in terms of dealing with climate change and the energy needs that alone will bring with it. Carbon sequestration, water desalination, etc... are all going to need serious energy behind them and will be knocking on humanity's door before the 2050s.
