So, I live at my big sis' place, she's still studying and all that, and I like to help her to make life a bit easier money-wise
regular light bulbs are around 60W right? If I buy these LED bulbs which only use like 4W would that make much difference?
I recently got a 27" LED monitor which uses 29W........... does that mean a big-ass screen like this uses less power than a lightbulb? o.O
maybe someone who cares about stuff like this could give me some tips ^^"

What you want is an eco-friendly light bulb, bro. Those last forever & use a lot less power. LED will use equally if not more power in the long run. =|

oh, really? o: eco-friendly seems logical... I'll ask around a bit then...

Also, depending on where you live...like if you are in the USA...... Use your lights, computers, washers, dryers and electrical stuff during off peak hours, like 6pm (I think :p ) till 7am and you will save some money.
If you want to do more: Unplug stuff that is not in use. Things that are plugged in will still use a tiny bit of electricity.

I'd like to address your question about Wattage by directing you to an equation:
Power = (Current)(Voltage). Power, measured in watts, is found by multiplying Current, measured in amps, by Voltage, measured in volts.
So that 60 W Bulb could have 3 Volts of electricity running through it, but have 20 Amps of current running through it, and that 29 W monitor might have, gee, I don't know, 14.5 V of electricity, but only have 2 amps of current running through it at any given time, effectively using less power despite the screen being bigger.
You have to also know that old-style bulbs require a lot of currents, which makes it so that a lot of electricity is spent. Eco-friendly bulbs are nice, and remember to keep the a/c on at a tolerable, but high temperature. That takes up a bit of electricity. If your sister has anything that requires 220V electricity as opposed to 110V electricity, then have her consider just buying a new electronic rather than paying extra for electricity as I have for 3 years after having moved from Korea.

@Muck: Hm, I don't think there's a specific time in which you pay less... as far as I know not o: And I'm trying to leave a lot of things off that I don't use. always a good idea
@FieldsForever: thanks for the info. I appreciate it ^__^
