Conclusion
•
Engagement in CSP will provide growing
chances for companies, utilities and new jobs
In future CSP will be one of the main energy technologies
Appropriate political conditions are essential
Investors need securities, e. g. by long term power
purchase agreements
•
Research and development is essential
Only national know how and capacities guaranty the
creation of local value and a dynamic national growth
•
CSP offer comparable easy options for an
engagement
CSP are complex systems consisting high- and low tech
components
