The Electricity Saving Thread

[CVT]

Cool. Ma testing nga itong LED bulbs na ito. I'm sure, given time, it will be the new standard in lighting since the cost will decrease with more people adopting it.

Sana may iba pang ideas?

How about using solar cells/panels? We have unlimited sunlight in our country....

Also, cost for this technology is starting to go down because of mass production due to increasing demand... Our first (multinational) wafer fab in the country, located in Laguna, are producing solar cells.........

Mahal pa rin nga lang ang upfront cost.....

(I use solar cells, for our garden lighting....)

Sunlight might be free but the system to convert it to electricity is expensive, even with current mass production levels (although I would admit, its much cheaper now than ten years ago). Still the problem is the technology must be able to pay for itself in a reasonable period of time, otherwise only people with "green" intentions would adapt this technology.

Another potential alternative is domestic wind turbine technology. You can install a small scale windmill and use that to charge a bank of electrical storage batteries for later use like night illumination. To offset the shortcomings, the system can be tied in with the national power grid to provide power when the storage batteries go flat.

OT:

I am not surprised that Philips has these since they're a 'European' company where the drive for LED lighting, which is very efficient, is strong.

On the other hand, I am surprised that v6dreamer has been using LED bulbs since my information is that the US is even further behind the rest of the world in using CFLs.....Meaning they're not very conscious of usage of electricity. I even remember seeing a recent episode of Ophrah where she is promoting the use of CFLs.....

LED lights been using here in U.S since 1990. Example, Las Vegas most of those neon gas sign has been replaced by LED also its very popular on plash light, christmas light, bar, disco house, most high rise condo, offices and casinos. LED is been here in the U.S for more than decade now but they are not popular cause they are very expensive only those people with enought money using on it. Let say's your house have more than 7 lights and replace those w/ LED, that will cost theme a fortune. People believe that if using incandescent bulb $1.90 to $5.00 per bulb(10,000 hrs life span) could save than much more money than buying $130.00 to 180.00 per LED bulb(50,000 hrs life span).

Actually, in 1992 lawmakers here in the U.S are talking about banning the century-old technology of light bulb to be replace by LED because of its contribution to global warming. Here in California LED will become standard by 2012 since those old type of bulb will be banned completly. By then the price will be much lower they were talking about $2.68 per watt compare to $26.00 dollars per watts(5 watts) that I bought that cost me $146.36 including tax. That is all I need since I cannot afford to replace my whole house w/ LED. Oprah is diff story, she is a BILLIONAIRE.

^^^ v6dreamer,- I was thinking more in the line that you're a Pinoy and that you're more adaptable to the changing technologies vs. the regular Americans....

As for Ophrah, in one of her recent shows that I chanced upon, she was with a group of women . And, these women, at least in my perception, have never realized the $ savings they would realize in using CFLs vs. what they're currently using,- incandescent bulbs....

On this topic,- goodbye Edison(?)....

* CVT, sometimes curiosity is a fact of life. People wanted to try one thing to another but, its very expensive. If my wife found out that LED I bought is cost $146 dollars she may have to call me moron. Its true, with that price I could change all the lights in my house w/ incandescent bulb and never to change it for at least a year or so. But, how are you going to explain that need to replace the whole lighting but it gonna cost us $1,500 compare to $50.00. Again, curiosity...but?

[pup2]

Baka kaya tinataasan ang cost ng kuryente dito sa Pinas para mabilis tayo maka adopt ng energy efficient technologies kasi masusulit ang high initial cost! hahaha. Anyhow, tungkol sa solar power, I have a different thread on that dahil pinag-aaralan ko na siya regularly at ito ang latest findings: http://tsikot.yehey.com/forums/showt...fordable+solar

Any idea how many watts ang LED equivalent ng 36 watt FL? How long kaya ang payback period?

You can also lower your AC thermostat to save electricity.
Insulate your roof.
Put your PC into standby when you wont use it for a short time.
If you have good ventilation, evaporative coolers can replace your AC.
Use timers on security or perimeter lightings.

we have 4 aircons at home. to save on electricity my wife gathers all 3 kids with her in one room and use only 1 ac.

but when i am home, balik sa rooms nila mga kids, solo kami ni misis. mainit sobra!

yebo,

bilis ng mga pangyayari.. dati mga post mo 2 daughters lang, 3 na pala

congrats!

Mainit ang ano:2hearts:

Seriously, have the aircon filters cleaned at weekly as much as possible.

Itong roof/insulation parang maganda i-try. Napansin ko hindi uso sa Pinas ito pero di ba it's just as applicable for heat as it is for cold? Ano bang material ginagamit dito? Sa kisame lang ba ito o sa windows/doors/walls din? Hindi ba very flammable yung material?

Polyethalyne foam insulation (spelling?). Comes in single sided aluminum and double side aluminum. Double side more effective. 10mm should be sufficent. Lagay mo sa roof/yero not ceiling. Fire resistant material ito. Dont use fiberglass insulation, sobrang kati.

Easily found in MC Home Depot. Price is around P70/square meter.

OOh. Cool! I'll try it! Another occasion for the use of my friendly spare electric meter!

Yes, im really surprised that so many houses in Phil still don't insulate their roofs... It's a friggin convection oven on top of your house if you don't insulate...

It depends on the budget of the home builder. My parents' house has two layers of insulation sheets in the roof.

Here's one for the books.

Replace your 40 watt fluorescent tube lights with a single Philips 23 watt Tornado CFL bulb. It provides the equivalent illumination of a 125 watt incandescent bulb with almost half the energy consumption of the 40 watt fluorescent tube.

i have some questions on this topic that hopefully someone can shed some light on (pun intended)

if you switch the light on and the bulb is busted does it still consume power? if it does, does it consume as much as if when the bulb is still working? if you switch the light on and there is no bulb attached to it?

if an appliance is plugged in does it still consume power even if it is turned off and it does not have a standby mode? (electric fan as opposed to tv)

does turning on an a/c consume a lot of power so that it is more energy efficient to leave it on overnight than to have it switch on and off (on 2 hours / off 30 mins, repeat)?

TIA for any advice on the subject.

Shopped around yesterday, di naman pala sobrang mahal yung LED bulbs eh, each 1W round or tear-drop shaped bulb costs around S$9 or about P260... Not that far off from CFL.

At the moment, the lighting applications of LED bulbs are a bit limited due to the brightness limits of LED but I do hope in the near future, they would be much much brighter.

BTW, those Philips LED being sold at ACE hardware is basically useless for lighting purposes and not to mention too expensive as well.

I'll try to find some LED bulbs when I go to singapore next month.

nope. Generally the circuit is broken when the bulb goes bust or is not screwed into the socket.

if an appliance is plugged in does it still consume power even if it is turned off and it does not have a standby mode? (electric fan as opposed to tv)

Nope. If your device has no stand-by mode, then it doesn't consume any power if off. But if your device has even a tiny LED light to show "power" then it consumes power (just a little bit).

does turning on an a/c consume a lot of power so that it is more energy efficient to leave it on overnight than to have it switch on and off (on 2 hours / off 30 mins, repeat)?

Nope, the act of turning on your A/C only consumes a small spike of power. The problem is you might be stressing the A/C's mechanical parts than you should be. Normally simply adjusting the A/C's thermostat to a comfortable level and turning it off for the last 30 to 60 mins before leaving the room would be enough to save you a lot of watts.

Some A/Cs already have a "double" plug where you can plug in an electric fan so the A/C's built-in timer will turn off the A/C and automatically turn on the electric fan to keep the cool longer with less power.
