: '''Energy resources''' are split into two groups; [[Renewable Energy Resource|Renewable]] and [[Non-renewable Energy Resource|Non-renewable]].

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.|} ====Future Trends====Many Governments are trying to decrease their reliance on [[Fossil Fuel]]s because:*The produce [[Carbon Dioxide]] which [[scientist]]s have linked to [[Global Warming]]*[[Fossil Fuel]]s will run out one day so we need an alternative to provide [[electricity]].The use of [[Renewable Energy Resource]]s is likely to increase over the next few years while the use of [[Non-renewable Energy Resource]]s such as [[Coal]], [[Crude Oil]] and [[Natural Gas]] are likely to decrease.{| class="wikitable"|-|[[File:UKEnergySupply1990.png|center|300px]]|[[File:UKEnergySupply2014.png|center|300px]]|-|colspan="2"|The [[percentage]] of the United Kingdom's [[electricity]] generated by different '''energy resources''' in 1990 and 2014. There is a clear decrease in the use of [[Coal]] and [[Crude Oil]] and an increase in the use of [[Natural Gas]] and a number of [[Renewable Energy Resource]]s.|}The current trend suggests that the use of [[Renewable Energy Resource]]s will continue to increase in the future. However, since [[Wind Power]] is unreliable and cannot be altered to meet demand, there will likely be a need for [[Natural Gas]] to generate [[electricity]].
