GCSE Bitesize was launched in January 1998, covering seven subjects. For each subject, a one- or two-hour long TV programme would be broadcast overnight in the BBC Learning Zone block, and supporting material was available in books and on the BBC website. At the time, only around 9% of UK households had access to the internet at home.
In 2015, 40.4 TW·h of energy was generated by wind power, and the quarterly generation record was set in the three-month period from October to December 2015, with 13% of the nation's electricity demand met by wind. [14] Wind power contributed 15% of UK electricity generation in 2017 and 18.5% in the final quarter of 2017. [15]
Electric power is the rate at which electric energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second. Electric power, like mechanical power, is the rate of doing work, measured in watts, and represented by the letter P. The term wattage is used colloquially
Energy mix of the United Kingdom over time. Total energy consumption in the United Kingdom was 142.0 million tonnes of oil equivalent (1,651 TWh) in 2019. [2] In 2014, the UK had an energy consumption per capita of 2.78 tonnes of oil equivalent (32.3 MWh) compared to a world average of 1.92 tonnes of oil equivalent (22.3 MWh). [3]
Energy (from Ancient Greek ἐνέργεια (enérgeia) 'activity') is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.
According to Weber, the ability to possess power derives from the individual's ability to control various "social resources". "The mode of distribution gives to the propertied a monopoly on the possibility of transferring property from the sphere of use as 'wealth' to the sphere of 'capital,' that is, it gives them the entrepreneurial function and all chances to share directly or indirectly in ...
A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal, oil, or natural gas, to produce electricity.Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator.
The ancient Greek understanding of physics was limited to the statics of simple machines (the balance of forces), and did not include dynamics or the concept of work. During the Renaissance the dynamics of the Mechanical Powers, as the simple machines were called, began to be studied from the standpoint of how far they could lift a load, in addition to the force they could apply, leading ...
