top energy wasting electronics and appliances & how to reduce energy waste and electricity leaking

Modern homes have dozens or even hundreds of electronic devices: vacuum cleaners, personal computers, printers, routers, mobile telephone chargers, telephone answering machines, CD players, video game consoles, hair-dryers, electric toothbrushes, electric razors, electrically powered towel rails, electric blankets, electric grills, electric ice-cream makers, electric bread makers, electric juice extractors, electric knifes, electric egg boilers, electric toasters, coffee machines and more, much more…

It’s just a small part of a much larger list.

Electronics and appliances Power Consumption & Energy waste

Typically, the type of devices mentioned earlier aren't energy-intensive, but their large number makes them responsible for about 10-15% (EIA) of the average household electric bills (USA).

This figure increases to about 50%, if we add the energy consumptiom of home appliances such as refrigerators, freezers, clothes washers and dryers, and dishwashers (American and European average).

And the problem is: a large part of the appliances energy consumption is associated with energy inefficient products or with electricity leaking (many devices use energy when they are in stand-by mode, without performing their principal function).

In other words: home appliances and consumer electronics are top energy wasters in a typical home.

Energy Star and high energy efficient devices: The best way to reduce appliances and electronics electricity waste

Energy Star appliances and electronics can reduce power consumption by up to 80%. That’s very significant over their lifespan.

Toaster: small electronicsThe first major step to reduce appliances and electronics energy waste is to buy energy-efficient devices.

When buying computers, home office equipment, external power supplies and home entertaining equipment (TVs, DVD players, audio systems, VCR, converter boxes…) pay attention to their energy labels: the Energy Star label (USA, Canada, Australia and New Zealand), the European Union Energy Labels, or other equivalent energy labels. That's important to select consumer electronics and appliances able to reduce energy waste.

reducing electricity leaking in appliances and electronics

Switch off or unplug electronics, appliances and chargers as much as possible.Many home electrical appliances draw power 24 hours a day.  So, why not group them together in a power strip? You can then turn them all Off or On at once.

Pay attention to the little red indicator lights on electronic devices. They should be an alert for us, even if their intended role is different. Home electronics operate in several modes, and when they are in stand-by or idle mode they continue to draw power (technically called electricity leaking).

Suggestion to reduce electricity Leaking (Standby and iddle consumption)

You can reduce appliances and electronics electricity leaking.

Standby power can be necessary for certain appliance functions such as remote control, telephone signal, battery charging, continuous display, monitoring temperature... But there are many cases when it is not necessary.

Here are a few suggestions to reduce electricity leaking:

When shopping, look for low electricity leaking devices, namely Energy Star products (they have lower standby).

Consider switchable power strips for groups of devices: the idea is to switch everything to zero with one single action. Power strips (with or without remote control) can include a switch to turn several devices off and on, and by plugging several devices into one same power strip you can turn them all off at the same time. You just have to group them according to the right criteria.

Smart power strips: there are many models (Conserve AV from Belkin, for instance), designed to cut all power to devices when they are turned off, while supplying electricity to things such as DVRs or other devices that need it.

Energy meters: these devices measure the energy draw of plug-in devices; it allows you to know the top energy wasters and estimate their energy costs. The market is now offering many energy meters.

High efficient battery chargers (Apple’s new AA-Battery Charger, for instance). They shift into low-energy mode at the right time.

Also do not forget to unplug the chargers of your portable phones and devices that are not being used; take a look to your wall sockets...

Do not underestimate their consumption. It's easy to waste hundreds of dollars per year. More details: Lawrence Berkeley National Laboratory

which is the Power consumption and the energy waste of Electronic devices and Appliances? Leaking electricity in domestic appliances and electronics

Which is the electricity consumption of a refrigerator, a clothes dryer, a oven, a TV plasma, a coffe machine, a can opener... you name it?

Current plasma TVs use about 3 watts in stand-by mode; desktop and laptop leaking electricity: 4 watts; printers leaking electricity: 2 watts; faxs: 4 watts... Note that these figures will be a lot higher in non-efficient devices, or when they are in idle mode… And if we add them all up, the total amount of energy waste may surprise you. Conventional rechargeable flashlights permanently plugged can consume more than $100 of electricity every five years. They are energy vampires... Prefer new rechargeable flashlights with LED bulbs; they use very small amounts of electricity.

Besides there are unexpected energy vampires (see box at right).

An old refrigerator can cost $200/year to run, while an energy-efficient unit costs just $50/year, or less.

Old refrigerators, freezers, clothes dryers, ovens, dishwashers, clothes washers, plasma TVs, kitchen stoves, LCD TVs, dehumidifiers or aquariums are very typical energy wasters. For a wide list, see below.

Gadget Mania

Another way to save money and energy, is to cast a critical eye on these devices, before buying or using them.

Are they really helpful or necessary to you? Are they time-saving or labor-saving?

In this age of electronic gadget mania, we are tempted to buy devices we don't really need. Some can be time-saving or entertaining, but many are rather useless and without any significant advantage over manual tools. We can save money and electricity by not buying or using them…

Electronics and appliances energy waste environmental Impact

Since the electricity which is generated in the US, Canada, Australia, UK and most other countries comes from power stations that are fuelled by fossil fuels, appliances and home electronics are ultimately responsible for billions of tons of CO2 emissions, each year.
