I still don't understand why we should be saving energy on interior lighting...
Most of the year in the UK we spend money heating the structures we live and work in.
The "inefficiency" of conventional tungsten lighting is given out as heat.
So why are we worrying about efficient lighting for interior spaces? If we were talking about Australia, where aircon is a significant energy consumer I could understand it; but in the UK we need to heat interior spaces 90% of the time.
Lightbulbs are particularly handy as heaters because most people turn them on when they're in the room, and turn them off when they leave; if anything it could make more sense to make them *less* efficient and give out even more heat.
Obviously the situation for exterior lighting is different; energy efficiency does make sense there.
As for why engineering and science are underwhelming the current generation; which would most teenagers rather be:
a) An internationally reknowned footballer, or...
b) an internationally reknowned engineer?
Let's see, who gets the fame? Footballer. Money? Footballer again. Poor job security, wow finally the engineer makes the league table; understandably it's a somewhat pyrrhic victory though ;)
