COGEN Europe, COGEN Spain and ACOGEN jointly organised the Annual Conference and Gala Awards Dinner entitled Cogeneration: Efficient and Clean Heat and Power for Europe’s Sustainable Energy Future. It took place on 24 and 25 October 2019 in Madrid, Spain. At the largest event of the cogeneration sector in Europe, we gathered business leaders, policymakers and key stakeholders from the energy sector to discuss the latest trends from the energy world. There was consensus that policy should support innovation and energy efficiency to build a carbon neutral economy by 2050 and that cogeneration is one of the key solutions to make the best use of the fuels of the future and develop an integrated energy system.
