The development of renewable energy sources (RES) is not merely a technical issue but a strategic topic with significant impacts on the economic stability, social cohesion, and energy security of the Czech Republic. Decisions made today in the areas of investment, legislation, and communication will have fundamental consequences for the coming decades. The energy transition affects households, municipalities, businesses, and public administration alike, and its success depends not only on technological solutions but also on public trust and the willingness of society to actively participate in the changes.
