How much household appliances consume and how to keep energy waste under control

One of the most common questions when talking about electric energy is “how much does a family consume every year?”; clearly the answer is not one and only one and, generally, depends on various factors ranging from one’s own energy habits and they reach up to type of dwelling where you live, including the number of members of their family and the type of appliances in home.

In short, there are many variables but to try to be more responsibleenergetically speaking, you can begin to become familiar with electronic devices that you use and on which, clearly, a large part of your energy consumption depends. Let’s find out more about it.

  • 1. How is electricity measured

    But before talking in detail about the most energy-hungry household appliances, it is worth briefly delving deeper into the discussion How is electricity measured?.

    In the International Metric System electrical power is measured in Watt (W)a quantity used to calculate the performance and consumption of various appliances in the home.

    When you read the bills you immediately notice that you are referring to very high amounts of current, such as daily consumption for example, or periodic consumption (bimonthly, quarterly, etc.). In this case, therefore, we need to talk about kilowatt (kW) a greatness that corresponds to 1,000 W.

    Given this, to fully understand your consumption, you need to take these figures and imagine them with time intervals of one hour, thus obtaining the kilowattoraalso called it will take them(kWh).

    Going up and referring, for example, to large factories, we arrive at Megawatt (MW) which corresponds to 1 million watts, which indicates very large quantities of current.

    This data can be read on the electric meteran instrument positioned inside each home which has the task of measuring the consumption of that property and communicating it to the service provider so that it can issue the relevant bill.

  • 2. The appliances that consume the most

    Having said this, we can go into specifics and try to outline a consumption trends of your home starting from the appliances in use and your own energy habits.

    It is clear that any household appliance needs a certain amount of energy to function, a fact that impacts consumption and bills.

    Naturally not all devices have the same consumption and if, for example, a simple battery charger has a minimal impact on the energy needs of your home, the same cannot be said for ovens, washing machines and all those medium/large sized appliances that we now commonly use.

    Let’s see which electronic products need the greatest amount of energy to function and the strategies for doing so make your home more sustainable.

    In first place there is certainly the conditionera device that is widely used especially in summer (although many also use it in winter to heat their home) and which has a strong impact on the bill.

    According to estimates, an average family in Europe consumes 450 kWh for powering these devices, amounting to a cost of around 15/25 euros per month depending on the hours of use and the energy class of the air conditioner itself.

    In addition to the costs on the bill, however, there is also something to consider the impact on the environmentwith this instrument which, according to estimates, produces on average 143 kg of CO2 every year.

    In second place among the most resource-hungry household appliances we find the phon. After all, it is a device that can reach a absorption of over 2 kW which, depending on use, can lead to rather significant consumption as well as the production of around 25 kg of CO2 per year

    Third place is occupied by refrigeratoran indispensable tool in every home, connected to the electricity grid 24 hours a day, 365 days a year.

    According to estimates, approximately the depends on it 25% of overall energy consumption with a total of 300 kWh per year and a production of approximately 102 kg of CO2 per year.

    Also there washing machine it is among the appliances that consume the most, and comes in fourth place in the ranking.

    Assuming an average of around 260 cycles per year, a washing machine (of a high energy class) has a average consumption of 240 kWh for an approximate cost on the bill of 63 euros.

    Much depends on type of wash which at low temperatures leads to energy savings of approximately 30%. Despite this commonality, a washing machine produces approximately 64 kg of CO2 per year

    In fifth place we find the microwave oven which can absorb up to 2.4 kW (depending on the function). In terms of environmental impact, however, it amounts to around 133 kg of CO2 every year.

    Sixth place for dishwasher which, compared to an average of 220 cycles per year, has a consumption of 220 kWh for 140 kg of CO2. To reduce consumption, of course, you can choose a ECO washing at lower temperatures and, perhaps, avoid the drying function which (in more modern products) has a strong impact on consumption.

    Finally we arrive at oven electric an appliance that, historically, is included in the ranking of the most energy-intensive ones, reaching around 105 kWh per year. A figure destined to grow, especially if high temperature cooking is used which, obviously, requires more power. On an environmental level, we are at around 66 kg of CO2 per year.

  • 3. How to keep an eye on your electricity consumption

    The first step to becoming more sustainable and keeping electricity consumption under control (and avoiding blows in the bill) is certainly to have greater consideration of one’s own energy habitstrying, when possible, to use electricity more responsiblyavoiding waste.

    And in this sense, the first step is use household appliances correctly. A typical example is that of washing machines, dryers and dishwashers which should always work at full load, so as to reduce cycles and reduce consumption.

    In addition to this it is also very useful to evaluate the purchase of devices of a higher energy class. Of course, this could correspond to a considerable expense, but over time it would lead to a rather significant reduction in consumption and emissions.

    Obviously it is also necessary to correctly eliminate old discarded products, taking them to the appropriate places ecological islands so that they can be disassembled and disposed of properly.

    Still on the subject of household appliances, it is always useful to keep in mind that i dispositivi in stand-by however, they have an energy consumption of approximately 30% per year. Turn them off correctly (or unplug) is a great way to save money and reduce your impact on the planet.

    Another option for keeping consumption under control could be to invest in a solar system. Certainly the cost of these jobs is quite high but there are several incentives state to draw on, which could make the costs amortized and in any case can be recovered in the long run an economic return interestingly, by selling excess energy to your supplier.
