Renewable Energy UK: Sustainable success as the UK powers 28 million homes

Renewable energy UK

An in-depth analysis by the Energy and Climate Intelligence Unit (ECIU) has shared the results of a groundbreaking renewable energy UK initiative which saw clean energy illuminate 28 million homes across the country. The organisation harnessed the combined forces of wind, solar, and hydropower sources, leading to this remarkable achievement. 

Onshore and offshore wind turbines, hydrogen electricity generators, and solar farms produced an impressive 90 terawatt hours (90TWh) of electricity energy in 2023. This marked a significant achievement as the dominance of fossil gas-fired power plants continued to decline. 

Decreasing reliance on fossil fuels

Despite the renewable energy sector’s success in meeting residential needs, the industrial and commercial sectors still require more. The data highlights the ongoing ascendancy of renewable power generation in the UK, with steady increases each quarter compared to 2019. 

In contrast, gas power generation saw a notable decline, with quarterly drops of 20-30 percent compared to four years ago. Other sources like biomass and combined heat and power also reported decreases, as indicated by the ECIU. 

Persistent fossil gas dependency

Despite these advancements, the UK is more heavily reliant on fossil gas than any other European country. Fossil gas still accounts for 40 percent of Britain’s electricity and 85 percent of home heating. This is even though prices soared due to the COVID-19 pandemic and the ongoing Ukraine crisis. 

This reliance, coupled with the UK’s inefficient housing stock, has resulted in significant energy cost burdens on households, documented by the International Monetary Fund (IMF). Moreover, high energy costs are expected to persist, with the energy price cap set to rise slightly from January 2023. Over the past two years, average energy bills have increased by 50 percent. 

However, the ECIU has stressed that increasing renewable energy generation, reducing gas dependency for electricity and heating, and improving household energy efficiency are crucial steps to alleviate the energy burden. Generating the same 90TWh of electricity from gas power stations would require over 180TWh of fossil gas, enough to heat 20 million UK households. 

ECIU Head of Energy, Jess Ralston has highlighted that every turn of an offshore wind turbine’s blades reduces our dependence on gas, vital for tackling climate change. In addition, as domestic gas supplies dwindle, the UK has a choice: accelerate clean energy or import more costly gas and ultimately, undermine energy independence. 


The UK stands at a pivotal juncture in its energy journey. The remarkable strides in renewable energy UK sources underscore a future where wind, solar panels, and hydropower could dominate the energy landscape. However, the persistent reliance on fossil gas and the inefficiencies in the housing stock present significant challenges. 

Every wind turbine’s rotation is a step away from gas dependency and towards energy independence and resilience. The path to more self-reliant, sustainable energy solutions is within reach, but it requires decisive action and an unwavering sustainability strategy that commits to renewable energy advancements.
