A massive solar eclipse will hit Germany on March 20th. This data shows why utilities worldwide should pay attention.

The world’s most sun-powered nation is about to encounter an unusual complication: the moon.

When a solar eclipse sweeps across Europe on the morning of March 20th, the moon’s passage in front of the sun will cast a sudden and giant shadow across Germany — a country whose reliance on solar energy is, by international standards, astronomical.

Although Germany is no bigger than the state of Montana, it boasts more than a quarter of all the solar electric capacity installed on earth. Its 1.4 million solar energy systems produce nearly 7 percent of the nation’s electricity. (In the US, solar provides about 0.5 percent.) And during the sunniest hours of the year, photovoltaic systems have satisfied up to half of Germany’s power demand.

May the most energy efficient team win: New England edges out Seattle in this year’s Efficiency Bowl

Is it true that Tom Brady — one of the most efficient passers in NFL history — may have schemed his way into the big game?

That’s the well-documented controversy surrounding the kickoff of this year’s Efficiency Bowl.

We aren’t NFL insiders, so we can’t formally comment on the pigskin pressure problem that is “Deflategate.”

We are, however, experts in utility innovation. And there’s no deflating the fact that both Massachusetts and Washington are national leaders in clean technology, consumer engagement, and energy efficiency. So, with Super Bowl XLIX just days away, how do the two teams — their stadiums, fan bases, cities, and states — stack up when it comes to getting the most out of their energy use? Let’s take a look.
