While purchasing electrical appliances for your homes, you must have come across terms such as voltage, ampere, and wattage. These terms are important to be understood in order to help an individual save money on the electric bill and be informed about energy consumptions by electrical appliances at home. Almost all the appliances have labels stuck on them which indicate the energy consumption ratings. Refrigerators, television, clothes drier, dishwashers, air conditioners, heaters, washing machines and lot more are supplied with ratings in them.

The labels have star ratings on them which show an approximate estimation of the amount of electricity it uses each year. Star ratings help you analyze the efficient brand than others. There are two types of labels which are 6 stars and 10 stars. A high energy efficient appliance has about 7 stars in it. When an appliance has more stars it means it is more efficient and can save you more on your electric bill.

Examples for energy consumption ratings

1)    A 7kg clothes drier comes with one star and 7 stars, the difference is that the one-star drier uses three times of electricity of the 6-star clothes drier. In the same manner, plasma TV with ½ star and 6 stars are available. When ½ star TV is purchased it used five times the electricity of 6 star TV.

How stars are awarded?

In order to provide star ratings, a number of complex algorithms are followed and standards are also tested across few types of appliances. When TV is taken, for example, assessors conceive that television is utilized for 10 hours a day and in standby for another 14 hours, so total energy consumption is calculated in that manner. The size of the screen is the main aspect taken into consideration. The same basis is used for screen area comparison, and their comparison is based on the home mode of viewing. Factors that influence energy consumption and luminesce of the screen are viewed. With this, the energy usage is ranked and star rating is achieved. The basic energy consumption defines one-star level for TV and when the energy consumption for the model is lowered another star is gained. 20 per cent per star is how the energy reductions are set presently. With the energy labels, customers are benefitted and save in their electricity bill too. in the same manner based on the performance and usage, star ratings  are awarded to all electrical and electronic appliances. These energy consumption ratings are ones that help you reduce cost on electric bills and show the performance of the appliance.

Different types of energy consumption ratings

1)    Energy star: is a government-backed symbol which is a trusted rating which helps save money and also guard the environment through its energy efficiency. The main intention of energy star rating was to reduce the emission of greenhouse gases and other pollutants. With energy start label people are able to click and purchase energy-efficient products and they have an opportunity to save energy bills without giving up comfort, features and performance of the appliance.

2)    European energy label: this type of energy label rates the products from A which means more efficient to G which means least efficient. These types of energy consumption ratings are present in washing machines, electric ovens, dish- washers, air conditioners and energy saving bulbs. Fridge, washing machine and dish- washers are given rates such as A, A++, A+++. Depending upon the energy consumption in KWh, grades are provided. An appliance is said to be more efficient when it has fewer grades.

3)    Energy saving trust: these labels are used for the ones that are most energy efficient. Tumble driers, washing machines, boilers, insulation glazers and hot water cylinders and more appliances have this logo. This type of logo is awarded to appliances in order to reduce carbon emissions.
