10 Energiewende Action Plan Overall concept Energy policy for growth and wealth Goals Secure, affordable and environmentally friendly energy supply Dimensions Grid Power Plants RE EnEff Research Federal, state, local authorities & EU: Framework Actors Economy / Companies: Private Investments, Business Segments Public / Citizens: Acceptance, Contribution, Investments Monitoring Annual Report & every three years Progress Report Source: adapted from BMWi

11 Energiewende Main Challenges Increasing electricity prices Willingness / ability to pay for renewable energies Distribution of costs between energy-intensive and other industries Decreasing international competitiveness of German industry? Social equity support for low-income households? Improving Energy Efficiency In all relevant sectors with appropriate measures (ordinances and incentives) Grid Stability Costs and acceptance of grid expansion to secure energy supplies Erratic RE-production of electricity requires storage capacity and demand management

12 Governmental Strategies and Efficiency Projects Governmental Instruments to Increase Energy Efficiency in Buildings and Industry Regulatory Policy Legal Energy Requirements Saving for Ordinance Energy Saving 2009 Obligation of Replacement Financial Support Loans Energy and subsidies KfWpromotional program: efficient construction /refurbishment Tax incentives Promotion Market dena Transparency efficient house quality mark Pilot Projects Information Qualification of Experts Source: adapted from German Energy Agency (dena)

13 German Energy Savings Strategies Objectives of Energy Concept by German Government (September 2010) New standard Climate Neutral Buildings to reduce primary energy consumption of buildings by 80% (2050) Doubling of refurbishment rate (1% 2%) New financial incentives ( CO2-building Refurbishment Program, Market Incentive Program to integrate RES in buildings, Energy Refurbishment Program, etc.) Energy Efficiency Funds Harmonization of legal framework for Energy-Contracting Exemplary role of government in the implementation of energy efficient measures Source: BMWi

14 KfW: energy efficient construction and refurbishment Energy efficient construction: Long-term loan for the construction or the first purchase of a KfW Efficiency House 70, 55 and 40 Maximum loan of Euro for one housing unit Effective interest rate starting from 1,4% Repayment bonus for KfW Efficiency Houses 55 and 40 (up to 10% of the loan amount) Source: KfW 2013

KfW: energy efficient construction and refurbishment Energy efficient refurbishment: Promotion of a comprehensive refurbishment that leads to a KfW Efficiency House 115, 100, 85, 7j0, 55 or monument

15 KfW: energy efficient construction and refurbishment Energy efficient refurbishment: Promotion of a comprehensive refurbishment that leads to a KfW Efficiency House 115, 100, 85, 7j0, 55 or monument Investment grants up to Euro for one housing unit Loans up to Euro (for one housing unit) or Euro for individual measures at favorable interest rates (effective interest rate of 1,00%) Promotion of specific energetic measures up to 10% of the eligible costs or rather Euro for one housing unit. Energetic measures that are considered, e.g. better insulation, exchange of windows or boilers/heating system Source: KfW 2013

16 CO2 building rehabilitation programme Summary Roughly 9,3bn Euro were allowed in public funds Between 2006 and June 2013, KfW approved about 1,2m loan and grant applications with an overall volume of 57bn. This lead to private investments of about 135bn Euro Over 3m housing units have been renovated or built energy efficiently, together with municipal projects As a consequence of these construction and refurbishment measures, CO2-emissions could be reduced by some 6,5m tons annually Source: BMVBS 2013
