Abstract
The new study by the Energy Watch Group and LUT University is the first of its kind to outline a 1.5°C scenario with a cost-effective, cross-sectoral, technology-rich global 100% renewable energy system that does not build on negative CO2 emission technologies. The scientific modelling study simulates a total global energy transition in the electricity, heat, transport and desalination sectors by 2050. It is based on four and a half years of research and analysis of data collection, as well as technical and financial modelling by 14 scientists. This proves that the transition to 100% renewable energy is economically competitive with the current fossil and nuclear-based system, and could reduce greenhouse gas emissions in the energy system to zero even before 2050.
The study concludes with political recommendations for a rapid integration of renewable energy and zero greenhouse gas emission technologies. Among the most important measures suggested by the report are promoting sector coupling, private investments (which should ideally be incentivised with fixed feed-in tariffs), tax breaks and legal privileges with simultaneous discontinuation of subsidies for coal and fossil fuels. According to the report, the transition to a global energy system based on 100% renewables can be achieved before 2050 if a strong policy framework is implemented.
