Fusion energy’s false dawn

A potentially exciting breakthrough shouldn’t detract from urgent energy needs

Energy Secretary Jennifer Granholm will announce a major breakthrough in nuclear fusion on Tuesday. Over the last two weeks, the National Ignition Facility of the federal Lawrence Livermore National Laboratory in California shot three lasers at a deuterium-tritium fusion fuel pellet, heating it until it induced a fusion reaction. This particular fusion reaction generated more power than used in the lasers shot at it.

Granholm will hail this as a “major scientific breakthrough.” And it is. But we’re still a long way away from the promise of bountiful clean energy that fusion promises.
