I´m a big fan of washing your clothes in cold water. It saves a ton of energy, isn´t as harsh on your clothing, and colours bleed a lot less. In my opinion, unless you´re washing a bunch of whites and really trying to get them clean, you should always was in cold water.
Agreed. With all the chemical advances in detergents anyways (I'll admit to not going totally green with all natural detergents), cold water vs. hot water doesn't make much of a difference for regular washing usage these days.
I think every bulb in my house except for the lamps are CF bulbs these days and that's only because the lamps haven't burnt out yet with their rare usage.
