CEESA integrates existing energy and environmental analysis tools in a unique way. Through a combination of life cycle assessment and energy system and market analysis methodologies, the project is able to meet three of the major challenges of future sustainable energy systems:

1. how to integrate the transport sector,
2. how to develop future power systems suitable for the integration of distributed renewable energy sources, and
3. how to develop public regulation in an international market environment.

The aim is to achieve a 100% renewable energy system. The project identifies which ways to follow in order to achieve this goal. The project combines system modelling, life cycle assessment, electric technology, and public regulation.
