​The UK has one of the most diverse range of sources of energy generation in Europe, with everything from nuclear power stations to offshore wind farms working to power the country. As Britain progresses with its green ambitions, it is also leaning more heavily on clean and green sources, meaning that the overall power mix for any given time can shift rapidly according to needs and availability.

For example, on moderately windy days, the majority of electricity now comes from wind turbines located both on and offshore. When there is no wind or it's cold, then peaking plants, which rely on gas, come into action to make up the shortfall.

Britain's electricity system relies on maintaining a mix of baseload power and intermittent sources. The former load comes from predictable, stable generation sources such as biomass and nuclear. This is supported by intermittent clean energy sources such as solar and wind, which rely on the weather conditions in order to operate.

The country also imports overseas energy via National Grid, which uses subsea interconnections that link the British Isles with France, the Netherlands, Norway and Belgium. These subsea lines allow national firms to buy and sell excess energy to suit their country's needs, especially energy that is being generated from renewable sources.

By 2030, the aim is that 90% of energy transmitted through these interconnections will be produced from net-zero sources.

The technology that powers the UK's electricity generation has significantly evolved in recent years. From 2024, there will be a further significant shift, as coal is phased out of national electricity generation entirely. The hope is that investment in renewable technologies continues to escalate as these technologies continue to evolve, hastening the UK's overall transition to net zero.
