Global Energy Assessment

1 United Nations Economic Commission for Europe COMMITTEE ON SUSTAINABLE ENERGY November 2010 Global Energy Assessment Thomas B Johansson Professor, International Insitute for Industrial Environmental Economics, Lund University, Lund, Sweden, Co-Chair, Global Energy Assessement, IIASA, Austria

2 Primary Energy (EJ) World Primary Energy 500 Renewable 400 Microchip Nuclear 300 Commercial aviation Nuclear energy Gas Steam engine Electric motor Gasoline engine Vacuum tube Television Oil Coal 0 Biomass Source: Nakicenovic et al., 1998

3 Challenges requiring actions on Energy a. Energy services for growing populations and economies b. access to modern forms of energy (the ~2 billion w/o access) c. affordable energy services d. secure supplies, from households to nations ( peak ) e. local and regional health and environment challenges f. climate change mitigation g. ancillary risks => Major Energy System Changes Needed!

4 These challenges must be addressed adequately timely simultaneously

5 Assessement Process leading to a Report and much more 25 Knowledge Modules, ~200 authors, geographically and gender diversified Stakeholder consultations External peer review Extensive dissemination Informing Rio +20 and other international, regional, national and corporate processes on energy and/or linked to energy issues

6 Supporting the GEA: International Organizations UNDESA UNDP UNEP UNIDO World Bank IIASA Country Governments/Agencies Austria Brazil European Union Germany Italy Sweden USA Corporations Petrobras TEPCO First Solar Industry groups WEC WBCSD Foundations UN Foundation Climate Works

7 Four Clusters of Knowledge modules: 1. The Challenges, nature and magnitude of change required 2. Resources and technology options 3. Pathways to sustainability, urbanisation, rural energy, and land use 4. Policies, energy end use and supply sectors, access, innovation, capacity development

8 this translates into a need for a major energy systems transformation Main elements: Energy end-use efficiency Renewable energies Carbon Capture and Storage (for CC only) Efficiency and Renewables are INSTRUMENTS for addressing all the challenges at the same time!

18 Economic development and poverty alleviation while mitigating climate change Multiple benefits concept Value all benefits (jobs, growth, security, health, local environment,...) Costs in terms of per tc misleading Energy efficiency Renewable energies

19 Major findings and conclusions Rapidly changing world Transformative changes needed on energy Window of opportunity exists Resources and technologies exist Rapidly growing role for renewable energies Electricity growing importance Policies and institutions critical Energy subsidies and R&D misallocated Capacity development worldwide
