Here is a bright idea!

World estimated electrical consumption for lighting is 17.5% of total. It is also estimated that the U.S. uses 20% of this total at a cost of $40 billion annually. The numbers are huge for lighting alone.

Greenhouse operations would clearly benefit from energy efficient lighting. Other less obvious operations like turkey production also benefit. As an energy savings strategy some turkey producers have employed lighting that increases intensity gradually in morning to simulate dawn and vice versa at sunset. This enhances the turkeys environment and they produce more. It also means significant energy savings.

Sounds like two birds with one stone to me and you have to like that.
