Newton’s second law teaches us that replacing incandescent with florescent bulbs saves you exactly no energy, assuming a building is being heated to a temperature higher than the outdoor temperature. In fact, it doesn’t make an iota of difference if you replaced all incandescent bulbs with plasma TVs. Almost all energy in a building quickly degenerates into heat.

 Nova Scotia, as I remember it , is pretty cold.

 Perhaps a course in physics ought be required to obtain a political science degree.
