Save The Energy, Save The World

Just because I am not one of environmental activists nor writers, it doesn't mean that I don't give a damn to global issues like stop-use-plastic-bags campaign or recentlywhat people all over the world talk aboutglobal warming. The world has been getting hot for sure, I can feel it myself right here in Jakarta.

If USA requires a perfect storm to cause blackout on southeast coast, a six-hour-non-stop rain is all what it takes to do so in Jakarta. Flood becomes our special guest coming every year. Soon after the presence of flood, the city undergoes a blackout for few hours or even days. This cycles have been running until now.

Once upon a time in early February this year, the blackout happened in my residence at the middle of the night. Me, who was about to go to sleep, apparently stayed awake until the sun rose because I couldn't tolerate the heat, remember? I desperately needed the air-con to keep me comfortable while I were sleeping.

I felt so miserable without electricity that night. Suddenly I realized how important to save the energy from now on.

Below are the easy, painless, and harmless tips for saving energy (by BBC News);

    TVs: On average a traditional cathode ray tube (CRT) television set uses 100 watts of power when in use and about two watts on standby. Newer LCD and plasma screens are higher users of energy, with the largest models consuming up to 400 watts when in use and about four watts on standby.

DVD players: Consumers can safely switch off most DVD players/recorders, hard disk recorders or video recorders purchased in recent years, according to the Energy Saving Trust. They should not need to retune the devices when they are switched back on or have to contend with the dreaded flashing clock as the machines usually retain their settings.However, manufacturers recommend that some satellite TV receivers be left in standby when not in use so they can receive updates.

Computers: It may not be practical to turn a computer on-and-off if it is to be used throughout the day. However, the Energy Saving Trust suggests turning the monitor off when not in use. Peripherals like printers and scanners should also be turned off when not in use. Leaving unnecessary items on standby is said to costs each household an average of £37 a year.


If chargers for devices such as mobile phones and MP3 players were unplugged when not in use, the UK could save enough electricity each year to power 115,000 homes. Chargers are not huge energy consumers in their own right, but across the UK those left plugged in unnecessarily waste over £60m and are responsible for a quarter of a million tonnes of carbon dioxide every year. If a charger feels warm when it is plugged in without being attached to a device it is still converting energy.


UK households spend £1.9bn on electricity every year for lighting. According to the Energy Saving Trust there is no truth in the belief that turning lights on causes a surge that uses up more electricity. "If you are going out of a room for half and hour, or even 10 minutes, turn the lights off," said Dr Paula Owen, of the Energy Saving Trust. "It does not harm the electricity supply or the bulbs. There is no point in burning electricity for no reason." If all UK households replaced one light bulb with an energy efficient one, the money saved could pay about 75,000 family fuel bills a year.


Washing clothes at 30C as opposed to 40C, uses 40% less energy and is generally as efficient, according to the Energy Saving Trust. Modern powders are designed to be more effective at lower temperatures. Over-dependence on tumble dryers can also contribute to energy wastage. Consumers are being encouraged to make sure they buy Energy Saving Recommended models when buying new appliances such as washing machines and fridges.


Turning the thermostat down by 1C can cut more than 10% from the average central heating bill. Similarly, reaching for a jumper rather than turning the thermostat up when it gets really cold can be effective. Check that your water isn't too hot. The cylinder thermostat should not need to be set higher than 60°C/140°F. And dripping taps can waste enough water in a week to fill a bath. Households with boilers over 15 years old are also advised to think about having them replaced it with a newer energy efficient model. High efficiency condensing boilers can save a third on heating bills. A major source of heat loss is through walls and windows so double glazing, closing curtains, cavity and loft insulation can prove to be cost-effective ways to save energy.

  1. Good point.

    But, what do you mean by "Turning the thermostat DOWN"??!! In Jakarta?

  2. @colson: I actually copy the tips from BBC, I know it's not applicable in Jakarta generally, I think it's common for office building and tv studio probably. Not sure though. Sorry my bad.

  3. It's useful tips to make a little change happens starting from our Jakarta. A little means something, instead of nothing. Better late than never!


  4. point number one is stupid.

    17" CRT monitor use 100 watts of power.

    17" LCD monitor use 35 watts of power.

    for a flat panel to have 400 watts of power consumption it would means it have to be larger than 60" in size - and that's because it's PDP/Plasma Display Panel. Even a 47" LCD panel only suck about 250 watts of juice - something that a 36" CRT panel take.

    So yeah. Better check and recheck the fact before you post an article from some monkeys who write on their own cage trying to be fed.

  5. I think the government in Indonesia is the smartest in energy conserving, they would cut off electricity or whatever they think necessary when the time come .

  6. mestinya bukan cuma warganya yg hemat listrik. hentikan pembangunan mal yg boros pemakaian lampu dan listrik. soalnya mal di jakarta sudah buanyaak..

  7. @anonymous: thank you :)

    @yuckity: thanks for your comment. I'm sorry for not re-checking the accurate fact of the article. It's just that, I took it from BBC News. It's really sad to know that even a BBC, has a mistake.

    @putu: hahaha you bet they are!

    @mpokb: you're right. It's sad but true :(

  8. klo sayah mah lebih suka dengan naik sepedah:D

    sehat klo pake masker, hemat BBM, hemat subsidinya juga, irit pula.

    uang transport bisa dialokasikan bwt sepatu sepeda baru :p

    *tetangga2 pada heran mobil digarasi ga pernah dipake kecuali pas ngapel*

  9. great post!

    by the way, i only have tv and computer and don't have freezer nor AC..
    i think it helps a lot when paying the electricity bill

  10. ah, then I really must confront my flatmates and myself when it comes to computer usage... the fact that our electricity credit runs out at an alarming rate (approx £1.50 a day) means that there are more DVD players and computer screens that need to be switched off.

    Ah, and also heaters in the room next door. My place sometimes feels like Hawaii.

  11. @spedaman: hmm knp ngapelnya ga pake sepeda juga? :P Asik kan klo bersepeda bareng berdua (save money buat bensin juga) hahaha.. Kidding :)

    @ika: thanks. Sure I think they help a lot ;)

    @mukuge: (Hawaii?!) LOL. You really have to tell them the truth :P

  12. wah nggak tahan panas dev? ACnya hemat energi nggak tuh...hehehe.

    salam kenal juga devi :)

  13. @hani: iya nih kebetulan ga tahan panas. Wah pertanyaannya to-the-point juga ya, hehehe.. Sebenernya ga tau sih, tapi mestinya sih hemat listrik ya *ngeles*

  14. Pada zaman kolonial dahulu, bangunan rumah ato gedung selalu mempunyai atap yang tinggi. Dengan begitu sirkulasi udara di dalam rumah/ gedung menjadi lancar dan suejuk tanpa AC. Beberapa bagian atap/genting juga dibuat dari kaca sehingga cahaya matahari bisa menembus ke dalam rumah. Jadi kalo mau hemat energi mestinya dimulai dengan menyesuaikan disain rumah/bangunan iklim tropis.

  15. Just cut the power to the whole house and walk to work :)))
    Looks like DAl Gore and David Suzuki are you cult leaders....
