Energy – guidelines

Energy has a twofold meaning within our context. On the one hand it refers to how much energy an appliance needs on a daily basis, and on the other hand it refers to its possible energy-savings.When choosing electric appliances it is important to note how energy-efficient they are. Most appliances carry a European Union energy label, marking how energy efficient they are on a scale from A to G. A is highly efficient while G marks it as quite inefficient. The energy-efficiency of any household appliance during its lifetime is very important for both the environment and your own budget. The cheaper product in the store can end up the most expensive one in the long run, when the energy cost is taken into the bill.Energy conservation is another factor to consider. Some products that need no energy can still be very important in energy conservation. Windows are one example. The energy conservation of houses is measured in so called U- values, i.e. the energy loss per square meter and the heat difference between inside and outside in Kelvin degrees (W/m2 K)There are various energy labels, such as: Energy star, GEEA, and the European Union energy label. These labels indicate how energy efficient the appliance is and can usually be found on computers and other various electric appliances.
