The end of the red light?

All electronic and domestic appliances sold in the current marketplace have a stand-by system incorporated (for e.g. a red light that allows for remote switching of the TV), and some of them cannot be totally turned off ever (unable to go into off-mode).

When a TV is in stand-by mode it consumes more in a year than it does when it is turned on, for example. And the same applies to other domestic appliances.

The stand-by mode represents approximately 12 % of the electricity consumption of the homes in developed countries, and more than 1 % of the global CO2 emissions.

It is estimated that, in the EU alone, there are 3.7 billion electronic products that by being left in stand-by mode consume close to 50 Twh, with an annual energy cost of 7 billion euros and an environmental associated cost of 20 million tonnes of CO2 emissions.

Manufacturers are already making an effort to decrease consumption in stand-by mode, and as a result it is estimated that by the year 2020 there will be 4.6 billion appliances with lower stand-by consumption, but it will still be set around the current 50 Twh range. 

GOOD FOR YOU, GOOD FOR THE PLANET has developed a technology - 100%Off, to take the annual stand-by consumption down to ZERO. 

It is adaptable to all appliances currently in the market and to those that will be manufactured in the future.

100%Off is a technology that may be implemented through plugs (much the same as the power strips that are turned off through a switch, hard switch-off) or as an electronic component that is incorporated in any appliance newly manufactured. 

100%Off works on three steps:

  1. It recognizes when the appliance is in stand-by status and when it is on working mode.
  2. When the appliance has been in stand-by for a certain amount of time, the algorithm within 100%Off (which can be configured through programming) automatically switches it off through a relay.
  3. 100%Off includes a green button with a wire that allows the switching on of the appliances when the user needs them again.

I agree that something has

I agree that something has to be done to reduce energy waste but I have a few issues with the points you raise here:

"All electronic and domestic appliances sold in the current marketplace have a stand-by system incorporated" - this is not true.  You can buy any number of domestic appliances that do not have a stand-by feature. My washing machine and kettle are two for starters.

"When a TV is in stand-by mode it consumes more in a year than it does when it is turned on" - are you really sure about that? That would mean that leaving your TV swicthed on all night would be better than putting it on stand-by! I've measure my TV and it uses 80W when on and 3W when on stand-by. Even so I physically switch it off when not in use.

I'm not sure of the motives behind your posting but you should get your facts straight before hand.

by the way, I see what you

by the way, I see what you mean by the second point (as in over a year if you only put your TV on standby when not in use instead of turning it off then it will use more power than it does in the time it is switched on over a year) maybe you could have phrased it better.

As you said that staetment

As you said that staetment is Untrue. In some cases I agreed with you, but I have an example for power saving point of you. In computers there is a "Hibernate" function. It saves lots of power and time. Most of the people use this function for saving energy. Have you tried it? It's amazing.

In reference to your

In reference to your comment on: "All electronic and domestic appliances sold in the current marketplace have a stand-by system incorporated" - this is not true

I will like to explain that Standby power is the current drawn by devices which are switched off - where "off" means a low-power state in which the device is not performing its primary function.

Modern devices pull down power from the mains 24 hours a day, year-round, and even when switched off - external AC/DC power supplies never stop drawing power.

The only way to stop the wheel of electricity meter is to unplug (not switch off) every device in the house. Most modern devices use AC/DC adapters with transformers that consume power even in no-load state (When the device they are attached to is not drawing any current), also, devices that get warm or have warm transformers when they are off.

This is one sort of Standby power; another is the power used when devices are switched on but are in a low-power state - waiting for user action. Laser printers that aren't currently printing, for instance, enter a low-power mode until called to print another sheet.

These state are beneficial, without them, printers and other devices would use massive amount of power each year.
