  1. Renewable Energy Costs and Benefits to Society RECaBS Anders Kofoed-Wiuff Ea Energy Analyses European Wind Energy Conference Warsaw, 23 April 2010

  2. Renewable Energy Costs and Benefits to Society - RECaBS • Scope • Estimate the costs and benefits of renewable electricity generating technologies compared to traditional energy sources • Why? • Lack of publicly and reliable technology data for energy planning purposes • Shed light on the externalities related to electricity production • RECaBS provides • User-friendly web-tool enabling anyone to make comparisons of renewable and traditional electricity generating technologies • Estimates of the most important externalities • Data and documentation relying on internationally respected sources • High-level of transparency – all data available at www.recabs.org

  3. Climate change CO2 abatement cost Environment SOx, NOx, dust, radioactive emissions, nuclear accidents Grid integration Infrastructure costs, balancing, capacity credit Security of supply Reduced price risk from fossil fuels Local benefits Job creation Costs elements considered Levelised life-time generation costs • Capital costs • Operation and maintenance • Fuel costs Including externalities

  4. Approach • Socio-economic point of view • The “real” costs and benefits to society • Discount rate: 5 per cent (user adjustable) • Tariffs, taxes and subsidies are not included • Reference fuel prices • Projections from IEA World Energy Outlook 2006 (user adjustable) • Technologies • Wind turbines (onshore/offshore) • Solar (photovoltaics, concentrating solar thermal power with natural gas back-up) • Bioenergy (large combustion, coal co-firing, gasifier, biogas, municipal solid waste) • Hydropower, small scale • Wave power • Competing technologies (coal power, including w. CCS, natural gas, nuclear) • Technology forecast for 2025 • From experts with insight knowledge and experience – including a hearing process with technology implementing agreements under the IEA • In combination with learning curve estimates

  7. Levelised life-time costs including externalities

  8. All input data easily accessible As online ’Input data’ … or from ’Downloads’

  9. Basic costs

  10. Basic costs& Externali-ties

  11. Top runners in cost reduction

  12. Conclusions • Technologies • Some renewable energy technologies are competitive today • The highest learning rates are projected for renewable technologies • Externalities • Climate change costs and system integration costs are the most important • Taking externalities into account improves the competitiveness of most renewable energy technologies • Tool • The interactive webtool allows stakeholders to examine the “real” costs and benefits of electricity generation to society

  13. Further development and promotion • Tool and documentation complete in its first version • Tool should be expanded; more features • More technologies; electricity, but possibly also heat and transport • Encourage professional users to use the tool; may lead to sustainable updating • Prepare analyses for workshops, conferences etc.
