Technology Transitions Towards a Green and Low-Carbon Economy

The present research analyzes over 300 pieces of literature and specifies the opportunities how a "EU Green Deal" on energy systems can be practically implemented in a country such as Austria, Germany, or any other state. In order to facilitate a real-world structural transition of the energy system towards non-carbon sustainability, both (i) technologies and (ii) underlying long-term trends are evaluated. (i) Results show present levels of feasibility for smart metering, micro-PV systems, electricity storage, heat storage, diverse industrial applications, smart cities, sector coupling, bridging time through energy storage, using the existing gas infrastructure, decentralized energy conversion, low-temperature district heating, heat management, large heat accumulators, the Big Solar project in Graz, Austria, industrial waste heat, island networks, and an equally needed "heat transition", while adopting a system dynamics viewpoint. (ii) Inspired by long-term trends as rendered visible through the "Global Change Data Base", especially that end-user-friendly energy carriers increase their market shares. Thus, a conclusion, a structural societal transition is an indispensable component of the "energy transition" worldwide, mainly based on solar and wind energy. The structure of an energy economy mirrors the views that a society has of itself: flexible, sustainable, and self-responsible.
