On the Nip Impressions calendar, May is energy trends month. There is hardly a timelier topic, except perhaps food trends, but Nip Impressions does not cover food and my doctor wants me to lose ten pounds, so I try not to think about it. I would guess a good half of the headlines in the popular press today are about energy. These then fall into two categories, security of supply and what to do about, what I will call "dirty" energy.
