If the College can insulate building X at a cost of $100,000 and, thereby, save $50,000 per year in heating costs, then, by all means, spend that money. Any investment that pays off after two years is worth doing.
But the College spends a lot (around a million a year) on goo-goo green sustainability type projects, things that don’t save money but do reduce carbon emissions and the like. Wisely, the College decided to skip much/most of that spending this year because of the crisis. (Morty and Greg Avis ’80 discussed the topic a bit at the Boston alumni meeting.) We should cancel all such spending for the foreseeable future. The College is too poor to worry about the global environment.
