In the Rhine-Hunsrück district, you can experience how energy transition works. Above all, however, the people there have proven that the municipal energy industry, together with civil society and the economy, is the fastest at reducing emissions. It all started with energy-saving light bulbs, continued with community wind farms and is far from over with e-car car sharing in rural areas, the heat transition and the smart grid. Because renewable energy is not only a means to the end of reducing emissions, but has long since become an important economic factor and locational advantage.
