Electronic That Consumes Most Electricity
My Personal Computer Set
Since the last couple of electric bills, I have been diligent in shutting down my computer when it is not in use but surprisingly my electric bill hasn’t changed according to the expectations. I thought I’m on the right track in reducing the household energy usage but by looking at the bill, not even close.
Good News And Bad News: The bad news is that we haven’t been able to reduce energy usage, but the good news is this has proven that computer usage was not the problem when it comes to high electricity bill, so computer freaks; you guys were never guilty.
Electric bill has always been my concern. I’ve decided to sort out the problem by figuring out which electronic consumes the most electricity. According to my research, if you were to make a chart of electronic that consumes most electricity and rank them in order of their consumptions of electricity, the list would turn out something like this:
| Electronic Appliance | Consumption (watts) | Cost /Hour ($) |
| Heat Pump or Air Conditioner | 15,000 | 1.50 |
| Water Heater or Clothes Dryer | 4,000 | 0.40 |
| Water Pump | 3,000 | 0.30 |
| Space Heater | 1,500 | 0.15 |
| Hair Drier | 1,200 | 0.12 |
| Electric Range Burner | 1,000 | 0.10 |
| Refrigerator | 1,000 | 0.10 |
| Computer + Monitor | 400 | 0.4 |
| Light Bulb | 60 | 0.6 |

Another electronic device that consumes a lot of energy: iPhone Charger

How much electricity will it consume It only consumes 10 watts of electricity and is economical enough to keep running 12 hours without supervision.

How about the 360?does it really consume lots of electricity?

I believe PS3 consumes more electricity than 360

Your figures are informative but they only tell part of the story, of course. You have quoted the wattage and prices for an hour’s usage in each case. Over a day, a month or a year, the actual cost of running each item would give a very different picture of the relative cost per item.
Although your aircon is shown as the most expensive by far, you hopefully don’t need to run it on every day of the year (or even 24 hours a day). Your refrigerator (and freezer), on the other hand does need to be on 24/7 (though the consumption would be unlikely to be 24kWh in a day because it has a thermostat to control it).
Where your table is useful, of course, is in pointing out which appliances can apparently give the greatest savings when turned off but, while it may give greater savings to use the aircon less, it might reduce the comfort level of your home to unacceptable levels!
The most effective energy efficiency is achieved by turning off even the small things, such as a 60W bulb when we don’t actually need it … with the caveat that, in the long run, the lifespan of things like energy-efficient light bulbs and computers may be significantly reduced by turning them on and off repeatedly!
An interesting topic and thanks for the table – I came across your site by chance while searching for something completely different!
