There are several measures that colleges can take to reduce their electricity bills.
The first measure that colleges can take, to reduce their electricity bills, is that of levering on solar power (and wind power if possible.)
The second measure that colleges can take, to reduce their electricity, is that of banning students’ from cooking in their dormitories. Under this arrangement, the students can be taking their meals in the college messes. But this can be hard to implement, because implementation would mean policing the dormitories, and the students are likely to be resentful of that.
The third measure that colleges can take, to reduce their electricity bills, is that of having the students living in dormitories pay their own electricity bills. That is as opposed to having the colleges pay for them. Most of the electricity cost incurred by colleges is on account of students’ activities in their dormitories. Of course, the students, who only get limited amounts of money in the name of federal student aid (see www.fafsa.gov) are likely to be bitterly opposed to this sort of arrangement. But there are colleges that have managed to undertake this sort of change, and college administrators can learn from them.
