[citation needed] In the home, the potential energy saving can be up to 12% on electricity bills. A VO device will lower the voltage to the most efficient level to maximise the savings on electricity consumption, so you may notice certain things taking a little longer, such as a kettle may take a little longer to boil.

International football finals are a particular problem as research has shown that 71% of people in the UK will watch them at home instead of public venues such as pubs. [4] The Grid predicted a pickup of around 3000 MW, equivalent to 1.2 million kettles being turned on at once, if England made the later stages of the 2010 FIFA World Cup. [4] [9]
Electric kettle: more than 90% [citation needed] (comparatively little heat energy is lost during the 2 to 3 minutes a kettle takes to boil water). A premium efficiency electric motor: more than 90% (see Main Article: Premium efficiency). A large power transformer used in the electrical grid may have efficiency of more than 99%. Early 19th ...
An 'efficiency' value for a kettle can be defined as the ratio of the energy required to heat a desired volume of water (e.g. 220 ml standard cup) to the energy required to boil the kettle. For the plastic kettle, the minimum volume mark corresponded to 350 ml. Add to this the additional volume for the heat capacity (105 ml) and the efficiency ...
In 2003 the housing stock in the United Kingdom was amongst the least energy efficient in Europe. [8] In 2004, housing (including space heating, hot water, lighting, cooking, and appliances) accounted for 30.23% of all energy use in the UK (up from 27.70% in 1990). [9] The figure for London is higher at approximately 37%. [10]
The UK’s domestic energy prices (including taxes) were 72.7 percent above the average for IEA prices in 2023, at 36.4p/kWh compared to an average of 21.1p/kWh. The data was not yet available for ...
