It’s solar power’s shining moment—the renewable energy source is currently growing faster than any other segment in the energy industry.

LAST YEAR, a new solar system was installed in the U.S. every three minutes. Creative financing solutions and plummeting panel prices have made solar widely accessible for homeowners and businesses alike. And by next year, experts predict that solar will actually be the cheapest form of electricity in many U.S. states.

I have written before about the Energiewende, or “energy transformation,” underway in Germany. In 2011, the German government made the monumental decision to phase out of nuclear power entirely by the end of 2022, and cover the electricity shortfall through energy efficiency and renewable power. Observers have debated ever since whether this decision was genius or folly. One thing that is indisputable, however, is that in response to this commitment, German engineers are innovating. The country is becoming, by necessity, a leader in managing renewable energy on a grand scale. This is a major challenge. As more and more intermittent wind and solar power is added to the national mix, Germany must develop new ways to manage its power grid to assure stability and meet demand—day and night, rain or shine.
