Average Energy Consuption a year assuming 10 300 minutes daily use.

1812.5 70 J/sec * 60 sec/min * 10 300 min/day * 365 day/year = 34.97E8 60E8 J/year

Assuming every female (54.8%) everyone on campus and no males use a blow dryer (some guys have hair driers)3.97E8 has a laptop

4.60E8 J * 1867 * 54.8% = 48.06E11 59E11 J = 48.06E8 59E8 kJ
