The History of All-Energy

Since it’s launch in 2001, All-Energy has grown from nearly 50 exhibitors and 350 visitors to 250+ exhibitors and a total attendance of 7,871 in 2019.

2001 - 2003 - Creating an All-Energy Future

The launch of All-Energy was held at the Aberdeen Exhibition and Conference Centre in February 2001 with nearly 50 exhibiting companies, 350 visitors and a 2-day paid for conference. The 2002 show saw total attendance of 800, and that was the upward trend that continued for many years.

2004 - 2007 - Record breaking growth

In 2004 the conference changed to a free of charge event which in turn saw All-Energy with visitor numbers soaring to 4,000 by 2007 in what proved to be the busiest and biggest event in its 7-year history.

2008 - 2011 - Parliamentary address

2008 - 2011 saw the UK and Scottish governments once again backing the event with Rt Hon Ed Miliband MP and Jim Mather MSP both featuring in the conference opening plenary session. Politicians continue to be actively involved up to and including present time.

2012 - 2015 - Move to new venue

The show continued to be held in Aberdeen but moved in 2015 to the SECC (now the SEC) in Glasgow, this resulted in attendee numbers increasing by 20% and exhibitor satisfaction going up by 28% since the previous show.

2016 - 2020

All-Energy continues to be held in Glasgow with strong support from key stakeholders. In 2017 Smart Urban Mobility Solutions (SUMS) was added to the show’s offerings, and in 2019 Dcarbonise, sponsored by the Scottish Government, Energy Saving Trust and Zero Waste Scotland, was co-located with All-Energy. The new event concentrates on energy efficiency, low carbon heat and low carbon transport (so now includes SUMS) the three vital pillars if net-zero carbon is to be achieved by 2050 (and 2045 for Scotland).


All-Energy returned to the SEC, Glasgow in 2022 for its first fully live show since 2019. Co-located with Debcarbonise, we celebrated 21 years of bringing together the renewable energy community and everything we’ve achieved together. Here’s to many more years of making connections on our journey to a net zero energy future!

2023 onwards

All-Energy and the co-located Dcarbonise held at Glasgow’s SEC on 10 and 11 May broke all previous records with total attendance of 9,577 – a 25% increase on the 2022 figure.

With its 250 exhibiting companies from 15 countries; close on 600 speakers in the phenomenal conference with its 11 conference streams and eight show floor theatres, the duo of shows provided a true, and free-to-attend, one-stop shop for all levels of learning about policy, strategy, new developments and innovative solutions.

2024 Records

2024 saw the attendance record at the UK’s largest renewable and low carbon exhibition and conference All-Energy, and the co-located Dcarbonise 2024, at Glasgow’s SEC, smashed by a staggering 21%. The increase in attendance was reflected by packed aisles, conference halls and show floor theatres with over 600 speakers during the 2 days. Smiles and congratulations were plenty from our 270 exhibiting organisations, many of whom have already re-booked for 2025’s silver anniversary event being held at SEC on 14 and 15 May. Exhibitors came from all over the UK and Northern Ireland, and also from the Czech Republic, Denmark, France, Germany, Ireland, Italy, Luxembourg, Monaco, the Netherlands, Norway, Portugal, Sweden and the USA.
