Electricity tariffs for households to go up by 5.4% in Q1 2010

[arcanehacker]

No choice the most practical solution is one our neighbours won't be happy with us pursuing.

:nuke: :nuke:

But I reckon we (and the rest of the global community) will be even less happy with them if they pursue it.

We don't really have the space for enough Solar farms and Wind Turbines.

So ultimately Singapore striving to to be a green city still kills the earth with the constant and increasing need for oil?.. nice.. the increase in oil price only make people pay more to the govt and never to reduce.. increasing number of people with cars is a great example..

Buy a generator and hook it up to your mains.

question: my skimmer is 28W and running for 24 hours. So based on calculation of 28x24=672. 672/1000=0.672kWh. 0.672x30days=20.16.

Based on current tariff 0.2521cents, so my skimmer skims me 20.16x0.2521=$5.08?

my calculation correct or not?

Not sure about your calculation.

But hey, do you need to have it on 24 hours?

Currently for me, I just turn it on at night till morning. Let's say about 11 hours.

No harm done leaving it on 24/7 especially with the kind of bioload you guys have It also helps with aeration.

I'm sure majority of us leave it on 24/7, some switch it off during feeding or when adding some additives into tank.

the consumption is only 28W, so ok one. The chiller is the killer by the way.

Boss has a pinned thread on this already http://www.sgreefclub.com/forum/index.php?showtopic=80504

Pasted here yo make things easier.

For eg. Product A has Power Consumption of 10 Watts

Product A Power Consumption : 10 Watts/1000 = 0.01kWh

0.01kWh X No. of hours used per day X No. of days used in a month = (Value)kWh

Amount to be paid per month = (Value)kWh X Tariff rate

so 28/1000*24*30*0.2521 = $5.08

you're right!
