To calculate the consumption of electrical appliances in kWh, you have to take into account the capacity and the length of use. As an example, we calculate the annual energy consumption of a radio alarm and a vacuum cleaner.
The energy used by household appliances is calculated on the basis of their capacity (expressed in watts) and the length or frequency of use. Take a look at the overview of the use per electrical appliance.
A laptop uses far less power and emits less CO2 than a desktop, but always be aware of the stand-by mode of your computer and peripherals.
A watt indicates the power of an electrical appliance. A kilowatt hour is the amount of energy that an appliance consumes when it operates for one hour.
Electrical power can be supplied to your home via a single-phase 2-wire connection or a three-phase 3- or 4-wire connection. Each system has its advantages.
The consumption of electric cars depends on the model and the manufacturer. Most of the electric vehicles can cover up to 100 kilometres with 15 kWh.
The numbers or scales on your thermostatic radiator valves do not correspond to a precise temperature but rather to a level of comfort. It's up to you to find the right setting!
To make sure that all consumers pay a fair price regardless of the caloric power of the gas received, gas consumption is calculated in kWh and not cubic metres.
The kilowatt-peak is a notion used to forecast the output of photovoltaic panels and therefore to compare them with each other.
The lifetime of an electric bike battery is not calculated in years but in number of recharge cycles. The most powerful batteries can hold up to 1000 recharge cycles.
Pellet stoves have several advantages: they are easy to use and efficient, as well as being environmentally-friendly. But they're also very expensive
A tonne of carbon dioxide is a return trip between Paris and New York by plane. In terms of volume, this represents a cube the size of a three-storey building, or 8.20 metres in edge length.
Internet use means energy consumption and, therefore, CO2 production. Information and communication technologies yearly account for about 4% of global greenhouse gas emissions. And this figure increases by 5 to 7% each year!
To bleed your radiators, just follow a few simple steps to remove air bubbles or sludge.

A dual hourly rate meter is used to distinguish between two rates for electricity: a slightly higher rate than the single rate during the daytime and a more advantageous rate than the single rate at night and during the weekend.
Damp inside the home has a detrimental impact on the occupants' health, the building itself as well as on the building's energy consumption levels. So it's vital that it is dealt with.
The dual hourly rate is based on the principle of two different prices for electricity: during the daytime it is slightly higher than the single rate, while at night as well as during the weekend and public holidays it is lower.

A heat pump powered by natural gas recovers the heat that is released as part of the combustion process. Which means the appliance delivers enhanced heat efficiency that outstrips its electric counterpart and it is well placed to replace a heating boiler.
Belgium uses up most electrical power between 5 pm and 8 pm on weekdays: offices and shops are still open for business, trains, trams and the underground system are operating at peak performance and people are getting dinner on at home. To avoid selective power cuts, there is only one thing for it: to drive down overall power consumption during these times.
Sometimes the public lighting is left on even during daylight hours. This may be due to repair work, a malfunction or an incorrect signal from Elia.
