Over the past twelve months from September 2023 to August 2024, the United Kingdom has shown a marked preference for low-carbon electricity sources, with over 60% of its electricity coming from this cleaner category. Close to none of the electricity is generated from coal, which remains at around 1%. Wind energy stands out as a significant contributor, generating just above 29% of the electricity, closely followed by gas, a fossil-based source that accounts for about 26%. Nuclear power contributes a substantial 13% to the low-carbon total, while biofuels, solar, and hydropower jointly add more than 18%. Notably, despite being a minor contributor on its own, net imports supplement the UK electricity grid with approximately 10%.
Looking forward, the UK can further bolster its low-carbon electricity generation by continuing to expand its existing nuclear and wind capabilities. The country's current infrastructure in these areas lays a strong foundation for further growth. Learning from international examples, the UK can draw inspiration from France and Slovakia, where nuclear power accounts for a significant majority of their electricity generation, at nearly 67% and 60% respectively. Denmark's success with wind energy, constituting 59% of their electricity generation, offers another model of green development that aligns well with UK ambitions. Emulating such strategies could assist the UK in making transformative strides toward cleaner electricity. Additionally, exploring opportunities to increase solar electricity in line with nations like Greece and the Netherlands, where solar energy contributes over 19%, could help diversify the UK's low-carbon portfolio further.
Tracing the history of low-carbon electricity in the UK, the 1980s were characterized by a substantial increase in nuclear generation, notably rising by 10 TWh in 1984 and around 7 TWh in 1985. However, the first decade of the 21st century saw a reversal, particularly with a decline of over 10 TWh in 2000 and again at different points, culminating in a significant drop in 2007 by almost 12 TWh. Fortunately, nuclear generation saw some recovery in 2009 with an increase of over 16 TWh. Wind power has painted a different picture, exhibiting consistent growth since its uptick began in 2013, momentarily stumbling in 2021 but regaining momentum in 2022 with an exceptionally high increase. Despite occasional dips, the UK's commitment to expanding clean energy remain unyielding, pressing on both the nuclear and wind power domains to ensure a more sustainable and environmentally responsible future.
