It’s Earth Week on Energy.gov! All week, we’re focusing on climate change, highlighting Earth Day events and sharing ways Americans #ActOnClimate — from climate scientists at the National Labs to high school students competing in the National Science Bowl. Follow along all week on Twitter, Facebook, Instagram and Google+, and let us know how you #ActOnClimate.

Energy Secretary Ernest Moniz will be on hand to throw out the first pitch at tomorrow night’s Red Sox Earth Day game, a chance to highlight the Energy Department’s work to fight climate change.

Secretary Moniz isn’t new to baseball. A Boston native and longtime Red Sox fan, he played center field in his younger years — and was once invited to try out for the Detroit Tigers.

These days, Secretary Moniz is known best for being an accomplished nuclear physicist and public servant. But his arm’s still pretty good. See for yourself in the video above, shot while the Secretary practiced his Earth Day pitch after work one night last week.
