I received the annual calendar for one of the universities that I will be teaching at this year.
In order reduce electricity they are cutting the first semester by 2 weeks.
Teachers are asked to make up the classes, or make it up with extra course work.
CUTTING CLASSES IS NOT A SOLUTION to SAVING POWER.
A good topic for a lesson might writing a letter to the university outlining alternative power saving strategies that could be implemented instead of cutting classes (which the students are paying for...).
