| style="height:20px; width:500px; text-align:center;" |This [[graph]] shows a typical example of how [[power]] usage varies throughout the 24 hours of the day in the [[United Kingdom]]. The early hours of the morning show a low [[power]] usage because most people are not using much [[electricity]] while there is a peak in the evening at around 8:00pm while people cook food and [[heat]] their homes.
A minimum of 20,000MW are needed throughout the [[day]] which can be produced by any available '''energy resource'''. However, a variable amount of [[power]] (around 20,000MW) is also needed, which can only be generated by '''energy resources''' which can quickly vary their [[power]] output.
