The European Commission has decided that member countries should decrease CO₂ emissions by 20%, reduce energy consumption by 20% and increase the share of renewable energy in the energy balance to 20% (3 x 20 rule). Achieving these goals in Poland requires considerable investment efforts, task coordination and the establishment of a relevant program, with a considerable share of EU funding, covering many sectors and involving the whole public. Professor Nowicki discusses technical feasibility of the implementation of the tasks, presents examples of sectors in which the best results can be achieved.
