In accordance with Finland's climate and energy strategy, Finland should achieve climate neutrality by 2035. This places demands on the future energy systems, where fossil fuels and peat are phased out in favour of more renewable energy sources. At the same time, Ostrobothnia is at the forefront when it comes to the use and utilization of wind power, and good regional development conditions also exist for solar power, energy storage and the hydrogen economy. The more flexible energy systems create previously unimagined opportunities for the greenhouse industry to both reduce dependence on peat and other non-renewable fuels, and to access cheap electricity and waste heat. However, in order to make use of and benefit from the rapidly arising energy surpluses and energy peaks generated by renewable energy sources, new ways of working are needed. The two-year project "A New Leaf – for the greenhouse production" has as its main goal to raise the understanding, the level of knowledge as well as the preparedness of the region's greenhouse producers when it comes to energy optimization and storage. In order to bring about this change, the project will go through different areas of the greenhouse's energy system – heating, dehumidification and lighting - and within all these areas: 1) Compile the information on what has already been tested and what results have been achieved, and to put the international greenhouse research results in a Finnish and Ostrobothnian perspective 2) Investigate and identify the future opportunities that the expansion of wind power and hydrogen plants create for the greenhouse industry when it comes to energy supply and energy optimization 3) Support the greenhouse industry by mapping the possibilities for energy storage and energy optimization from both an economic and production efficiency perspective, based on modelling, simulations and profitability calculations 4) Disseminate information to the target group and give producers the tools needed for decision-making and to make their own energy use more efficient. Through these measures, the project aims to 1) strengthen the operating conditions and preparedness of the Ostrobothnian greenhouse industry, 2) create better conditions for the greenhouse producers to make good investment decisions and develop their business in a sustainable and profitable way, and 3) create better opportunities when it comes to exploiting the opportunities that renewable energy sources bring. The concrete result of the project is an info package with proposals for different energy systems for the greenhouse industry and their applicability to Finnish climate conditions. The info package is based on the interviews, investigations and results that emerged within work packages 1-4, and provides a comprehensive picture of the situation, both regionally and internationally. Firstly, the info package contains a contemporary analysis based on information gathered in work package 1. The info package also contains a chapter on heating based on the investigations in work package 2, a chapter on dehumidification based on the investigations in work package 3, and a chapter on lighting that is based on the investigations in chapter 4. The information package is supplemented with information sessions and workshops where the collected knowledge is disseminated to the target group. Novia can also take note of various issues and development ideas that the greenhouse producers bring forward at the workshops, and work on these further. Thanks to the project's activities, exchange of knowledge and experiences, case studies, the information package and information sessions, we have achieved the following results at the end of the project in 2025: 1) The level of knowledge and awareness of the region's greenhouse producers has been raised when it comes to energy optimization, storage and implementation of new alternative energy systems and ways of working 2) Better conditions for the greenhouse producers to make good investment decisions and develop their business in a sustainable way and so that it maintains profitability 3) Enhanced communication and exchange of best practices, and inspired and motivated greenhouse producers that feel equipped to face the challenges of the future 4) The operating conditions and preparedness of the Ostrobothnian greenhouse industry has been strengthened, and the producers are better equipped to take advantage of the opportunities that renewable energy sources bring.
