German Engineering: Innovations in Energy Management

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.

Solar makes sense in a lot of places and for a lot homes, so here is how to make sense of whether solar makes good cents for you. And, yes, solar does make sense in the Midwest, at least I think so.

IN ANY RANKING of the world’s countries from richest to poorest, Bangladesh can reliably be found near the bottom. Yet according to the International Renewable Energy Agency (IRENA), this South Asian nation of 150+ million people is leading the world in the installation of home-based solar systems. Approximately three million residential solar systems have been installed in Bangladesh in the past ten years, and new systems are being installed at the blistering pace of 80,000 per month.
