Q11: What's worse: CO2 emitted by a gas-fuelled car or the environmental effects of hybrid car batteries?
A: According to te UK-based Environmental Transport Association (ETA), the most efficient conventionally powered cars are slightly less detrimental to the environment than their hybrid counterparts. However, it points out that the current crop of hybrids won't evolve without customers willing to invest in what is still frontier technology!

Q12: If I turn my appliances off but don't unplug them, will they still use up some electricity?
A: NO. And that applies even if the plug is switched on or if the socket has no on/off switch. The exceptions are appliances with a standby mode, which include most battery chargers. As a rule of thumb, if there is a light on, a clock ticking, or the transformer feels warm, it means it is eating up energy. And that can be a substantial proportion of the amount of electricity consumed by that appliance when in use. A television set-top box, for example, uses around 18 watts while it is on and almost 17 watts on standby!

My television set-top box uses ~1W when in standby mode and ~17W when on. Please remember that those numbers are examples -- not absolute truth.
