It doesn't affect it at all today. It may revolutionize the energy sector in the 10, 20, 50 years or so it takes to make practical commercial fusion reactors. All this latest experiment has done is prove that yes, we can create a controlled fusion reaction that gives off more energy than required to sustain it within certain criteria. It's a stepping stone, a scientific milestone. Nothing more. In this context "controlled" only means it's not a bomb. We've known how to do large scale "uncontrolled" fusion reactions for a long time. They're called thermonuclear bombs.
