How to reduce its electricity consumption ?


Fossil energies currently used (oil, coal, gas, etc) are partly responsible for climate warming and involve health risks and the environment. In addition, these resources are not inexhaustible and will rarefy. The future of humanity is thus with renewable energies (solar, wind, hydraulic, geothermics, etc) whose ecological print is minimal.
Moreover, the world needs important energy saving. To avoid a catastrophic climate change, the emissions of gases for greenhouse effect must be reduced 80 to 90% from here 2050. To save energy constitutes an important part of the solution (40%) via the following actions: better isolated dwellings, apparatuses electric household appliances and cars energy savers, a durable food and, before any thing, of the behavioral changes. With a little good sense, you can already save a few tons of gas for greenhouse effect in your house.


The label energy

Following various European directives (92/75/CEE, 94/2/CE, 95/12/CE, 96/89/CE, 2003/66/CE, etc), most apparatuses electric household appliances, the electric bulbs and the cars (not in all the countries for the moment) must have an label-energy (or étiquetteÉnergie).
The energy efficiency of the apparatus is evaluated in terms of noted classes of energy efficiency of A++ to G. the A++ class being that with the ideal efficiency, the G least effective.
The labels also provide other useful informations to the customer, helping it in his choice between various models. In the 2007 all categories of apparatus do not comprise yet the classes A+ and A++. Medium 2007, the category A++ refrigerator did not seem to be marketed.


Electric household appliances: councils, tricks and easy ways to reduce its consumption of energy
The Label for the electric household appliances

Label-energy understand at least four parts:
References of the apparatus: in this part, appears the precise references of the apparatus, the model and the manufacturer.

The energy class: a code color associated with a letter (of A++ to G) which gives an idea of the consumption of energy of an apparatus electric household appliances.

Consumption, effectiveness, capacity, etc: this part gathers various information according to the type of apparatus.

Noise: the noise emitted by the apparatus is registered in decibels.


Refrigerators and freezers
Here the scale of the indices of energy efficiency, this index is calculated for each apparatus starting from its consumption and of the volume of the compartments, while taking of account the type of apparatus. This index is thus not expressed in kWh.

   A++ <30
   A+ <42
   A <55
   B <75
   C <90
   D <100
   E <110
   F <125
   G >125

Moreover one finds on the label:
The consumption of energy in kWh/an.
Capacity of fresh food products in liters for the combined refrigerators and apparatuses.
Capacity of food products frozen in liters for the combined freezers and apparatuses.
For this category (and this category only), there exists also a Energy+ label, for the apparatuses even more sparing than the apparatuses of category A (categories A+ and A++).
They account for 25% of your consumption of electricity.
The purchase of a new refrigerator or freezer, choose a model energy saver. The old refrigerators of more than 10 years consume inevitably more energy than the new models. We advise you to replace them, in so far as the new apparatus is of class A+ or A++.

The Councils of use:

Avoid placing the refrigerator beside a source of heat (furnace, cooker or heating) not to cause overconsumption.

Install your freezer or deep freezer in the coldest parts (garage or cellar).

Never place hot food in the refrigerator, initially let cool it until room temperature

The apparatuses cold ventilated are énergivores and are useful only in very wet climate, to avoid the formation of white frost.

Think of well regulating the temperature: 5°C is enough with the conservation in a refrigerator, and - 18°C in a freezer. Each degree less consumes 5% of energy moreover.

You can install a thermometer for refrigerating freezer/in order to control the temperature. This kind of thermometer is on sale from 2 €.

Avoid overloading your refrigerator: that increases the consumption of energy and decreases the shelf life of food (the cold air circulates less better).

Avoid leaving the open door, think so that you will take in your refrigerator before opening it.

Regularly check the sealing of the joints of the doors: if your apparatus starts to frost too quickly, that can be the sign which he flees.

Take care to sufficient leave space between the apparatus and the surrounding walls. The condenser emits heat and the air must be able to circulate suitably to ensure a good refrigeration.

Think of de-icing your apparatuses completely every 3 months: 2 millimetres of ice increase the consumption of energy of 10%!


Washing machine

For washing the scale of energy efficiency is calculated for a detergent on the cycle “white” with 60°C and brought back to 1 kg of linen. The unit is thus kWh/kg of linen.

   A <0,19
   B <0,23
   C <0,27
   D <0,31
   E <0,35
   F <0,39
   G >0,39

A+ apparatuses appeared in this category (washing machine, dryer with exchanger of temperature)
Moreover one finds on the label :
The consumption of energy in kWh/cycle.
Effectiveness of washing classified of A to G.
Effectiveness of drying classified of A to G.
The speed of drying in tr/min.
Capacity of the drum in kg.
The water consumption in liter.
The type of drying (condensation or evacuation) for the dry-linen and combined apparatuses.
Noise for washing in dB (A).

A washing machine consumes much water and energy. The associated costs with the consumption of energy and water of the washing machine for one period of 15 years use rise with 1400 euros in a family home. Choose a powerful and sparing washing machine.
The major part of the energy which a washing machine consumes is used to heat water. A machine of the type “hotfill” is a special washing machine equipped with a connection for warm water and a connection for the cool water which, thanks to that, can be directly connected on warm water arrival. Water can thus be heated via gas, fuel oil or solar energy, instead of electricity.
There exists still another possibility of heating water via gas, fuel oil or solar energy. That is done via an apparatus connected in front of the washing machine. This apparatus allows the mixture of warm water resulting from a water-heater with cool water in order to obtain the temperature desired by the washing machine.
Choose a model which consumes little water. Moreover, you can use rainwater for your detergent
Completely fill your machine before the throw, without exaggerating however. The maximum capacity which is indicated by the manufacturer represents the weight in kg of dry linen. A rule easy to retain is that it is necessary to leave the place of a fist to the top of the linen. When the drum is not filled, do not forget to engage the key “half load”.
Wash the linen requiring an high temperature with 60°C and not with 90°C. Temperatures lower partners than longer durations of washing make it possible to obtain a result of identical washing for a consumption of weaker energy and also spare the textiles. Generally, prefer the programs at low temperatures, a cycle with 30°C or with 40°C, three times less energy consumes than a cycle with 90°C.

Choose the economic programs for the not very dirty linen since, in this case, it is not necessary to carry out a preliminary wash.

Regularly clean the filter by putting it under water and control the joints regularly.

Remove the surplus of limestone. A bicarbonate of soda spoon in the detergent vat slows down the creation of limestone. If your water is calcareous, to prevent that your machine is not furred, make, 3 times per annum, a washing with vacuum with 60°C with a scaling substance for washing machine. It is more economic and much more effective than the pastilles antiliming.

Minimize the use of the hair drier. If you buy some one, prefer an apparatus of class A and also choose a washing machine which dries your linen to the maximum (1400 turns/minimum minute). An effective drying in your washing machine will reduce the consumption of your drier from 20 to 25%).

Use respectful products of the environment


For drying the scale of energy efficiency is calculated for drying on the cycle “white dryness” and is brought back 1 kg of linen. The unit is thus kWh/kg of linen.

   A <0,55
   B <0,64
   C <0,73
   D <0,82
   E <0,91
   F <1,00
   G >1,00

These apparatuses are large-scale consumers of energy. If one can do some, the clothes line remains the most ecological solution and least expensive! However, by choosing powerful models and by complying with certain rules of use, it is possible to reduce the costs generated by the dryers.
If you have an exit of evacuation, choose a drier with evacuation. The apparatuses running on gas are most sparing. They consume 10 times less electricity, make it possible to reduce by 60% the invoice of energy (electricity + gas) and dry the linen at a 40% high speed compared to an ordinary electric dryer.

For the dryers with condensation, not requiring evacuation, the models with heat pump are to be privileged. Only these dryers reach an energy efficiency of class A.
Some councils of use:

Think of cleaning regularly, preferably after each use, the filter anti-cuddly toys, without water. The circulation of air will be only better and you will support heat exchange air/resistance (energy saving and better output).


Energy efficiency is calculated for 12 covers, it is thus its consumption to wash these 12 covers. This index is thus expressed in kWh for 12 covers.

   A <1,06
   B <1,25
   C <1,45
   D <1,65
   E <1,85
   F <2,05
   G >2,05

Moreover one finds on the label :

The consumption of energy in kWh/cycle.
Effectiveness of classified washing of A to G.
Effectiveness of classified drying of A to G.
The number of covers.
The water consumption in l/cycle.
Some councils of use:
Prefer the programs at low temperatures (60°C): you will save 30% of energy compared to a washing with 90°C.

Think of cleaning the filter regularly: you will increase his lifespan and you will decrease his consumption of energy.

Use respectful products of the environment


One finds on the label:

Effectiveness classified of A to G.
The consumption of energy (conventional furnace) in kWh.
The consumption of energy (furnace with pulsated air) in kWh.
The volume of the apparatus in liter.
The type (small/average/large).

A microwawe oven consumes as much, to see more, that a traditional furnace.

Preferably reserve the microwawe oven with reheating, rather than with cooking.

Avoid its use for food containing much water or cooking in water (like vegetables), like for the large portions.

Be wary of the very greedy furnaces with pyrolysis in energy and prefer the furnaces with gas, plus energy savers.

Open your furnace the least most often possible during cooking and never during pre-heating, because you lose several degrees each time.

Pre-heating is often superfluous: two minutes with 70°C are enough.

Defrost in advance your food with the free air (or in the refrigerator: your food thus will defrost while reducing the consumption of the refrigerator!): you will thus save the consumption of the microwawe oven.
