How to save electricity?

Actually I still don't quite know: for washers, does the label show that they are energy- or water-efficient? I thought they are water drops and not ticks (like the aircon, dryer and fridge?

from what I understand, the ticks are meant to refer to energy consumption. Don't think they refer to water consumption.

But I found this:

https://app.mels.nea.gov.sg/Pages/Search/PublicSearchProduct.aspx?param=goods&type=p

Under energy efficiency, only has fridge, aircon and dryer.
Washer is not there, so maybe for washer it is not energy that is measured?

BTW, if anyone want to find energy-efficient appliances, can use the link above to check which products are good...

A man once asked God: \"God, what is a hundred thousand years to you?\"
God replied: \"A second.\"
The man asked again: \"OK, um... so what is a hundred thousand dollars to you?\"
God replied: \"A penny.\"
So the man asked excitedly: \"Wow... ok, God, may I have a penny?\"
God replied: \"Sure... in a second.\"

:rotflmao: very funny!

on earth hour please turn off electricity at your house. It will do more good rhaan all of us combined.

:torchme: ya boi... feel so bad... I for one that never leave tap running while soaping, brushing teeth, or even hand washing I would not turn on the tap until I am ready to rinse.... If dds/dh caught wasting water they will get :spank: from me.

Must, must really do something about this wasteful trend... its time.

Why don't you just install a sensor tap..... save the trouble..

LED confirmed not as bright if talking about the same wattage. But it is supposed to last much much longer, although it is like 3 times as expensive. It is also supposed to be better for the eyes as there's something that's more constant although I can't remember it now -- saw this 'dunno-what' meter at those light shops when I went scouting for lights when renovating the house. The meter kinda showed LED doesn't flicker much c.f. with conventional lights and therefore protect the eyes more.

LED runs on DC. The lamp fixture will contain the necessary electronics to convert the AC to DC. The illumination is constant, it does not flicker.

FL runs on AC. The light actually turn ON/OFF 50 times a second, same as the frequency of the household power supply. Hence it flickers.

Some flick-free lamp actually contains some electronics to increase the frequency to much higher, so that it doesn't affect the eyes as much.

Still, nothing beats LED when it come to flicker-free illumination..

So, Harlequin, another reason to do your part for the environment.. :evil:

So LED lights good for eyes. Is it more energy-saving than energy saving lights?

Nebbermind:

Back to LED - although they are known to last long, their performance in terms of brightness is not maintained throughout its lifespan.


I ever spoke to a supplier/manufacturer maybe 3 yrs back and based on their experience, they feel the savings one gets is not substantial vs a energy saving fluorescent lamp. But for commercial or industrial use, where other high power lamps are used, the returns are much better.

Less flicker and so better for eyes. But less bright would be worse for eyes. Effectively no difference then?

May I know which kind of led is good for reading lights that look like a tube fixed on the upper hung cabinet above the table? I have been introduced to T5 and there are china made and us made. Is there difference between the two made besides the price?

Psst BM, if you reveal how much you're spending on PUB bills, the consequence will be that everyone else here will immediately think that they're being very thrifty liao. Haha!

eh....we are referring to the hotpot that is constantly heating water right? one kettle, fill up the thermos flask. Bb drink bottle milk also not 100% hot water right? Anyway, it's individual/family choice. if family is happy to pay that utility charge, all is good.

If we want to have an extra thermos flask of hot water, instead of getting another hotpot, would it be better to use the existing hotpot to boil water (and transfer to thermos), or use an electric kettle (don't ask me to use gas as I don't want to end up with a burnt kettle).
