Top 15 Companies affiliated to renewable energy in UK

The United Kingdom is one of the oldest ruling civilizations in the world and they are also one of the oldest civilizations to produce electricity, with waterwheel technology dating as early as the 2nd century AD. Similarly, Windmills first appeared in Europe during the middle age while the first electricity-generating wind turbine was recorded in 1887. In 1878 the world’s first hydroelectric power was installed in England. However, thereafter, most of the energy produced has been through coal. 

The scene of renewable energy in the UK started during the 1970s with the global oil crisis and miner’s strike. Today, renewables produce more than 20% of the UK's electricity and are set to increase with several schemes that provide financial support for renewable energy such as Renewable Obligation Certificate Scheme (ROCs), Feed-in tariffs, and renewable heat incentive. 

What are the major sources of renewable energy in the UK?

The major sources of renewable energy in the UK to make electricity and fuel include wind, waves, marine, hydro, biomass, and solar. 

With over 10,000 wind turbines and a total capacity of 22 GWs, the UK is ranked as the world’s sixth-largest producer of wind power. 

Biomass is the largest renewable energy source in the UK, catering to transportation, and energy generation. Biomass is also an important part of the UK's commitment to reduce greenhouse gas emissions by 80% by 2050. 

Hydroelectric power is a well-established technology in the UK running on the natural flow of river or dam storage techniques. Similarly, marine and wave technologies that use ocean energy to produce electricity are increasing with major co

Solar photovoltaics is another major source of renewable energy in the UK with nearly 9GW of installed capacity. 

Other renewable energy sources in the UK include: Geothermal energy and community energy systems based on solar and wind technologies

Renewable Energy Produced & Consumed in the UK

Image by Marco Chilese on Unsplash

Like a trend in almost all countries, renewable energy produced in the UK is usually consumed in 3 major sectors: electricity, heat, and transportation. 

In 2020,  Low carbon generation in the UK reached a new record high at 62.1 percent of generation, with fossil fuel generation reaching a new record low at 35.4 percent with a sharp fall in gas generation. 

Provisional calculations show that 13.2 percent of final energy consumption in 2019 came from renewable sources.

Renewable electricity capacity was 47.4 GW at the end of the first quarter of 2020, which accounted for 47 percent of total electricity generation. 

Renewable heat accounted for 7.9 percent of total heat consumption.

Renewable energy used for transportation accounted for over 13.2 percent of total consumption

THE UK government has pledged to hit a target of net-zero carbon emissions by 2050 and this has seen a drastic increase in the use of renewable energy sources for utility and commercial purposes. In the last 6 years, the renewable electricity output has increased 4 folds while Scotland is determined to generate enough renewable energy to power the economy. 

The Renewable Energy industry in the UK is expected to continue to expand over the next five years, with better policies supporting the production and consumption of renewable energy. The decrease in the cost of renewable energy technologies will be a major factor to make renewable energy more affordable and accessible to the end customers. 

In this fight to decarbonize the economy, fight global warming, and increase the share of renewable energy, the companies affiliated with renewable energy in the UK will have a vital role. Even companies that do not directly produce renewable energy are making the shift to cleaner energy. ​​​​​​​
