This. If you have to build a steam turbine to convert the energy from your fusion reactor into electricity, it's never going to compete with solar and wind power in most of the world. Doesn't mean that there won't be applications (if you can make all those lasers compact enough, submarines, ships, and ultimately spacecraft come to mind), but grid electricity is doubtful.
