All-Energy 2019 saw a 12% attendance increase on the previous year, attracting an overall turnout of 7,871.
The show also saw 250 exhibiting companies and 500 speakers.
First Minister Nicola Sturgeon addressed audiences during the opening plenary session, while Scottish Energy Minister Paul Wheelhouse took to the podium on the second day.
The event is the UK’s largest renewable and low carbon energy exhibition and conference.
Event director, Jonathan Heastie of Reed Exhibitions who own and organise the annual event, said: “The two co-located events complemented each other showcasing their core values in the exhibition and in conference and seminar programmes.
“All-Energy has been serving the needs of the renewable and low carbon energy sectors since 2001; and now we have Dcarbonise championing the end-user in need of cost-effective energy efficiency and low carbon heat solutions in line with the Scottish Government’s ‘Energy Efficient Scotland’ programme.
“Low carbon transport also fitted under the Dcarbonise ‘banner’ and included a hydrogen-powered double decker bus from Alexander Dennis, a range of low carbon and electric vehicles, a fuel cell range extender, the Shell-sponsored area featuring two of its eco-Marathon teams, our ‘Arrive and Drive’ feature, and in the conference with five 90-minute sessions.
“We look forward to continuing feedback from exhibitors, speakers and visitors and to welcoming all of them to the 20th All-Energy and 2nd Dcarbonise on 13 and 14 May at the SEC next year.”
