Renewable Energy Institute

What Renewable Energy Institute does

The Renewable Energy Institute (REI), headquartered in Edinburgh and operating since 1975, is a privately held professional training and certification body focused on renewable energy and energy efficiency. It delivers a portfolio of 300+ accredited courses spanning solar photovoltaic, wind, hydrogen, energy storage, electric vehicles, heat pumps, biomass, carbon finance, and artificial intelligence applications for energy, offered through a 24/7 web-based learning management system supporting online on-demand video, live virtual classrooms, in-person sessions at 21 partner universities across Europe and the USA, and bespoke corporate training. The Galileo Master Certificate (GMC) has been awarded for over 40 years and the Master in Renewable Energy Award (priced at US$5,382 full-pay, with quarterly and monthly instalment plans) provides up to 15 GMCs over an 18-month programme accumulating 280+ CPD hours; Expert Certificate pathways bundle three courses for up to £1,040 in savings.

REI monetizes primarily through individual course fees and the Master Award, supported by an annual Professional Membership Programme (£210/year, requiring 30 hours of CPD), one-off conference and event fees (notably the biennial European Conference and REvision summits run in partnership with UNEP and IIR), and corporate bespoke training. The customer base is dominated by individual professionals (engineers, project managers, lawyers, consultants) supplemented by multinational enterprise buyers such as Amazon, Ford, Siemens, NHS, World Bank, Coca-Cola, NATO, and the European Investment Bank, with training delivered to roughly 5,000 individuals per year across 150 countries. The company is family-controlled under CEO Paolo Buoni and Director Marco Buoni, holds ISO 9001 and CPD Accreditation Service certifications, and has been self-sustaining without external venture or private equity funding across its 51-year history. In October 2025 it launched the AI Centre for Energy Innovation and Technology in partnership with the European Centre of Technology and Centro Studi Galileo.
