Using a low energy bulb how much energy are you saving?

Question

Using a low energy bulb how much energy are you saving?

Answer 1

You will only be using about a quarter of the electricity and the bulb will last 3 or 4 times longer.

Answer 2

I changed all my bulbs about a year ago... Total saving in Dollars......$1.02 not including the cost of bulbs and effort made or mercury going into the soil when they are dead

Answer 3

I saved about $5 the first month using them in one ceiling light and 3 lamps.

Answer 4

A 60 watt incandescent is roughly equivalent to a 15 watt CFL or 3 to 7.5 watt LED.

So if you power each for one hour, you're saving 45 watt-hours with the CFL and 52.5 to 57 watt-hours with the LED.

Answer 5

apparently 135W ( 3 60W replaced by 3 15W, although I don't have any record of it, and don't seem to have my electric bill handy)

Answer 6

Ordinary bulbs   Energy saving equivalent

25W ...............................6W

40W ..........................8-11W

60W ........................13-18W

100W ......................20-25W

The saving can be 'up to 80%' but using the higher figures in the table, realistic savings will be between 70% and 76%. One tends to leave low energy bulbs on longer than one would normal ones (if one is at all power conscious) partly because you know they cost less but also because it shortens their life to be turned on and off and the cost of the bulb is not insignificant, even though they are quoted as lasting up to 10 times as long as a normal bulb.

Answer 7

1000 watts of power costs on average 7 pence for an hour. So a 60watt bulb will run for 16.66 hours for 7 pence. Using an energy bulb of 11 watts will give the same light out but will run for 90 hours. Doesn't sound a lot but imagine if you changed all the bulbs in your house.

Answer 8

A regular incandesant bulb only uses 10% of it's energy of actually lighting a room while the remaining 90% is given off as heat. Useless heat really.   Very wasteful.  Those guys above already answered your question...I'm just adding how useless incan. bulbs really are.

Answer 9

I dont know about the energy, but if you drop it, mercury is released.  You have to clean it really well and put the bulb in a plastic bag to throw out.  

I'm green, but I stay away from these.

I'm not sure which bulb, I think its those curvy curbs you see. It might be compact fluorescent, not the regular bulbs we see.
