Thinking at EU, national and regional level and acting locally is not a contradiction, but rather a dynamic energy policy. If someone tells you that they can explain the opportunities and possibilities of environmental and climate aid within a few minutes, then you should be extremely skeptical. This book CLIMATE.help.EU introduces you to the numerous tangents of climate aid and the energy transition in an exciting way. The many interfaces of the energy transition are not necessarily immediately obvious, but the regional and local swarm contributions are of great importance for the common multiple. The renaturation, the sustainable bridge technologies, the climate-neutral future technologies, the sector coupling (Power-to-X) of electricity + heat + gas products + fuel products with hydrogen . . . the regional and local opportunities are manifold and have already triggered a booming job engine with German technology know-how and German infrastructure know-how in addition to the proof of concept for the energy transition. Hydrogen energy storage is the comprehensive bracket for the sustainable energy transition with environmentally neutral technologies to reduce climate change. This book CLIMATE.help.EU would like to engage you in an imaginative dialog on the energy transition and has a broad target group: interested citizens, students and teachers, municipal and regional actors, urban planners, politicians, entrepreneurs, actors in the construction industry, in agriculture and in the energy industry . . . as well as basically all people who keep asking themselves what sustainable action can look like. In the most positive sense, this book CLIMATE.help.EU actually dispenses with cautionary scenarios and starts directly with the presentation of the promising possibilities in the potential grid of the EU energy transition. The success of the energy transition depends crucially on the start and speed of implementation of defined goals, which requires determinati
