Electric Eye

I was going to have an afternoon nap today but upon hearing my CPU fans humming i was suddenly struck with this thought: I leave my PC on for almost 6 out of 7 days a week, so how much electricity costs am i running in a month or a year? And for that matter how much are my other devices draining?

So after some sketchy research into the subject and some rough guesstimation on my part (meaning for example, in the case of my PC i just took 75% of the max. power my power box can supply), this are some figures i came up with (based on Singapore Powers 1st July '07 electricity tariffs per kWh; 20.52cents) :

-My PC running @ ~330W w/o LCD monitor:
$397.26 if left on 24/7 for 1 year, $33.10 a month

- My Grundig LCD TV @ 200W:
$71.13 if used 7 hours a day for 1 year, $5.92 a month

- Xbox 360 @ 160W:
- $58.82 if used 7 hours a day for 1 year, $4.90 a month
(power usage compared to a PS3/PS2 in this article)

- Daikin Air-Con @ 900W:
$91.66 if used 2 hours a day for 1 year, $7.64 a month
(that's $366.64 a year if used 8 hours a day!)

- Tower Fan @ 40W:
$54.72 if left on 24/7 for 1 year, $4.56 a month

Anyway these are the main things that are used in my room daily. The biggest cost i can save is definitely on air-conditioning (and i only turn it on when friends come over). If i use my fan for a whole year i will still pay less than using the air-con for 2 hours a day. And despite what my parents say, me playing games for 7 hours a day is not the main reason for the high electricity bills.

Again i want to stress that all the figures are just guesstimation that take do not take into account electricity loss through plugs or energy saving settings etc. Reading for 15 minutes and spending another 15 minutes doing calculations did not make me a SME.

And how about environmental impact? Everything above is presented in dollars and sense so if you ask me how much does saving $50 a year in electricity slow down global warming, i seriously do not know.

I just suspect doing whatever little bit we can to reduce wastage (especially if you're a hug-a-tree kind of person) will do much more than say, having a 'Live Earth' concert and having millions of people around the world tuning in on their TVs.

There's lots of good reading online if you really want to find ways to cut billing costs or just do your part for the environment.

The latest song from Guitar Hero 3 that looks set to dwarf 'Jordan' in terms of sheer difficulty is Dragonforce's "Through Fires and Flames".

If you like the song you can go to the Dragonforce official site and download the full mp3 version of the song for free (it's the full 7:20 version that will be used in GH3 compared to the 5:02 of the MTV).

Personally i find the song very epic/fantasy-themed and fun to sing along to. Alex says it sound very 80s ala the Transformers (the fantastic cartoon movie, not the crappy shit that came out last month) soundtrack. Bert says it sound very patriotic and that if you swap National Education lyrics in it will probably be a good national song. Anyway the lyrics are as follows:

On a cold winter morning, in the time before the light
In flames of death's eternal reign we ride towards the fight
And the darkness is falling down and the times are tough all right
The sound of evil laughter falls around the world tonight

Fighting high, fighting on for the steel
Through the wastelands evermore
The scattered souls will feel the hell that is wasted on the shores

On the blackest waves in history
We watch them as they go
Through fire, pain and once again we know

So now we fly ever free
We're free before the thunderstorm
On towards the wilderness our quest carries on

Far beyond the sundown, far beyond the moonlight
Deep inside our hearts and all our souls

[CHORUS]
So far away we wait for the day
For the lights are so wasted and gone
We feel the pain of a lifetime lost in a thousand days
Through the fire and the flames we carry on

As the red day is dawning
And the lightning cracks the sky
They raise their hands to the heavens above
As we send them to their lies

Running back through the mid-morning light
There's a burning in my heart
We're banished from the time in the fallen land
To a light beyond the stars

In the blackest dreams we do believe
Our destiny this time
And endlessly we'll all be free tonight

And on the wings of a dream
So far beyond reality
All alone in desperation
Now the time is gone

Lost inside you'll never find
Lost within my own mind
Day after day this misery must go on

CHORUS [Guitar Solo Duel!!]

Now here we stand with their blood on our hands
We've fought so hard now can we understand?
I'll break the seal of this curse if I possibly can
For freedom of every man

CHORUS
