The only that surprises me about this is the fact that they had to write a story about it. I could never logically get my arms around how this was supposed to save us energy, anyway.
For example, households may draw less electricity for lights at night, but will use more power in the early in the day as they wake to darker and chillier mornings.
Yeah, it only really works if we can wake up in the daylight. Way to go Congress.
