4 Energy efficiency is fundamental for reaching the climate change objectives World energy-related CO 2 emissions abatement in the 450 Scenario Source: IEA, World Energy Outlook

5 High real efficiency effect in Germany rather than de-industrialization Change in aggregate energy, intensity decomposed into structure and efficiency effect, % % % % % % % Notes: efficiency effect represents the composite economy-wide adjusted energy intensity metric. IEA 15 member countries are those for which sufficient data is available to undertake analysis Source: IEA, indicators database 5

6 A huge potential to increase energy efficency remains untapped Energy efficiency economic potential by sector Note: These energy efficiency potentials are based on the IEA New Policies Scenario outlined in the World Energy Outlook Investments are classified as economically viable if the payback period for the up-front investment is equal to or less than the amount of time an investor might be reasonably willing to wait to recover the cost, using the value of undiscounted fuel savings as a metric. The payback periods used were in some cases longer than current averages but they were always shorter than the technical lifetime of individual assets. Source: IEA, World Energy Outlook

7 In the building sector there is still a lot that can be done to save energy Energy efficiency potential in buildings Biggest potential in the building sector (40% energy consumption). One of the strongest levers to cut carbon emissions is to enhance the energy-efficiency of buildings. German firms are global market leader. German industry can provide all technologies required. 7

11 What are best practice technologies for harvesting low hanging fruits in energy efficiency? INDUSTRY The major part of electrical energy demand is used in electric drives Electricity demand in the industrial sector Electricity purchase of the industrial sector in Germany Total: 222 TWh el 70% of which are for electric drives = 155 TWh el 54% of which are used for pumps, conveying devices etc. ( Motion ) = 84 TWh el Source: Siemens 11

12 What are best practice technologies for harvesting low hanging fruits in energy efficiency? BUILDINGS Solutions to lower energy demand in buildings Smart home Hot water system Insulation Renewable energy Insulation (roof) Restoration (doors) Simming systemy Intelligent household appliance Ventilation system Building automation Insulation basement ceiling Drinking water production Intelligent heat distribution Heating plant Contracting Restoration (face of the building) Lighting Insulation (perimeter wall) Window restoration 12

13 How can private and industrial consumers be encouraged to deploy efficiency measures? (obligations vs. incentives) Implementation of Energy Efficiency Networks WHAT: Joint implementations of energy efficiency networks by governments together with the private sector on a voluntary basis. WHY: Networks create a positive culture towards energy efficiency with a low bureaucracy environment. HOW: An network consists of company members and an energy consultant. They share knowledge and ideas on how to improve the energy efficiency of their production processes and discuss ways to implement efficiency measures. RESULTS: The networks were able to reduce their energy consumption by roughly 10% over 4 5 years resulting in significant financial savings. 13

15 What do private and industrial consumers need to be encouraged to deploy efficiency measures? Outlines of a political framework to improve energy efficiency We need Removal of market and investment barriers. Motivation campaigns and a competent consumer advisory service. A consistent regulatory framework including all regulations related to energy efficiency. A harmonised and appropriate funding policy for the building sector. Individual solutions for every type of investor and building. 15
