Think of all the energy that goes into making a single solar panel. Quartz and copper must be mined. The raw materials must be converted into wafers, then encased in protective material. And after panels leave the factory, they must be shipped all over the world.

Now imagine these consequences spread over four decades—the environmental cost of the solar industry. Given all the research, development, and production time that goes into making any one panel, a skeptical solar-buyer might wonder: Has the solar industry on the whole really saved any energy at all?

To that concern, a new analysis answers: Yes.

The solar industry probably paid off its long-term energy and climate “debts” in 2011, a study published this week in Nature Communications finds. Since its inception in 1975, the solar-panel industry has almost certainly prevented more greenhouse-gas emissions than it emitted. It has also cumulatively produced more energy than it initially required.
