In December, the National Ignition Facility announced a breakthrough in nuclear fusion technology: for the first time, a nuclear fusion reaction created a net gain of energy, and since that reaction doesn’t emit carbon or other pollutants, a lot of people have proclaimed that we are one step closer to achieving “the holy grail of clean energy.” But as exciting as this breakthrough is from a scientific perspective, “holy grail of clean energy” is a bit of a stretch. Ethan breaks down why today’s clean energy sources are way further developed than nuclear fusion and why nuclear fusion isn’t necessarily required for a clean energy transition in this week’s “Tip of the Iceberg.”
