Each year we track how much energy the Lombardo Welcome Center makes and how much it uses from May 1st through April 30th. While we didn’t know it at the time, last year by 2:15pm on September 27 it had already made enough energy to cover its energy needs for the entire year. Ultimately, it would go on to make 75 percent more energy than it used and become the first certified zero energy building in Pennsylvania, and one of the highest energy performing buildings in the country.

The Lombardo Welcome Center is doing even better this year.  Between May 1 and Aug 31 it made 105,472 kWh. So far this month it’s making about 660 kWh each day.  That means that within the next several days it should make enough energy to cover its annual energy use, which, based on last year, should be about 115,853 kWh.

Can you guess the exact date and time that the Lombardo Welcome Center will have made enough energy to cover its annual energy use (115,853 kWh)?  The first individual to guess the date and time (or closest without going over) when Lombardo will have generated 115,853 kWh wins a Build Your Own Educational Solar Kit.  

Participation is limited to Millersville University faculty, staff and students.

Guesses must be submitted by 11:59 PM on Wednesday September 11.
