Solutions exist,
Summary and Outlook
Technology:
• Different technological options exist to allow a high share of renwable power sources in the grid like
Super Grids, advanced electricity storage technologies and sector coupling.
• Maturity of the technologies is not guaranteed
• A „best“ option is difficult to identify and depends on many constraints
Legislation:
• Energy legislation is quite complex and uses many different tools
• New tarif structures are vital to enable many of the new technologies like flexibel demand options
Cooperation:
• Cooperation between countries and even continents is vital to strengthen technological developments
• Mistakes can be avoided
