Where are we? Baseline is important.
Technology price reduction can help

International agreements and national laws
Maybe fear or awareness can help?
We know it will be paid off but?

What are we supporting?
Subsidies and costs of EU energyEcofys 2014 by order of: European Commission
Support schemes for renewables• Public interventions such as support
schemes remain necessary to make certain renewable energy technologies competitive. To avoid distorting energy prices and the market however, these schemes should be time-limited and carefully designed. The EU has issued guidance on support schemes to help governments when they design or revise support schemes.

Support schemes can help… but?

Savings, security of supply, cleaner environment, local jobs, investments, SEAP….. are not enough?
Local heroes may help?
Integrate energy and water systems through Low Impact Hydropower Plants
or energy and water desalination
Integrate renewables into transport sector
Integrate sectors and bussinesesThe Tekniska verken group 100% owned by the City of
Linköping since 1921
Close the cycle locally…
Start by small steps and demonstration plants
Conclusions • Local leaders must be identified and encouraged• Innovation and demonstration need support • Multi-level governance approach• Strategies and actions must be identified, planned
and coordinated on EU, macroregional, national, regional, city and local levels
Conclusions
• Focus on self-consumption and prosumers• Use renewables to integrate different sectors• Integration of energy and materials flows• New partnerships, business models • Integrated smart energy systems
