  1. Determinants of Renewable Energy Technology Adoption in Developing Countries Birte PohlGIGA German Institute of Global and Area Studies International Energy Workshop (IEW)University of Cape Town, South Africa

  2. Outline • Motivation and Research Questions • Stylized Facts • Related Literature • Econometric Analysis • Summary of Findings • Policy Implications and Conclusions Birte Pohl – Renewable Energy Technology Adoption in DCs

  3. Motivation and Research Questions • no binding emission reduction targets for developing countries (DCs) • many DCs already produce electricity from renewable energy sources such as hydropower or non-hydropower (biomass, geothermal, solar, wind) • analysis of environmental technological change has mainly been carried out in a developed country context • the technological change process is likely to differ across countries (Del Río González 2009)  Which factors drive renewable energy technology adoption in the power sector of DCs?  How can the adoption of these technologies in DCs be promoted? Birte Pohl – Renewable Energy Technology Adoption in DCs

  4. Stylized Facts Table 1: Importance of Hydro and Non-Hydropower across World Regions Data Source: EIA. Notes: Hydropower includes small and large hydropower. Non-hydropower includes biomass, geothermal, solar and wind. Birte Pohl – Renewable Energy Technology Adoption in DCs

  5. Stylized Facts Figure 1: Share of Electricity Generated from Hydro and Non-Hydropower Data Source: EIA. Birte Pohl – Renewable Energy Technology Adoption in DCs

  6. Stylized Facts Figure 2: Per Capita Electricity Generation from Conventional Energy Sources, Hydropower and Non-Hydropower in kWh Per Capita Data Source: EIA. Birte Pohl – Renewable Energy Technology Adoption in DCs

  7. Related Literature Brunnschweiler (2010), Finance for Renewable Energy: An Empirical Analysis of Developing and Transition Economies • power sector • non-OECD countries, 1980-2006 • Random Effects, GMM • finding: financial development has a significant positive effect on renewable energy technology adoption Birte Pohl – Renewable Energy Technology Adoption in DCs

  8. What is new? My paper differs with regard to • country sample • dependent variable (aggregate: non-hydropower) • control variables • econometric specification Birte Pohl – Renewable Energy Technology Adoption in DCs

  9. Data • to be explained: electricity production from non-hydropower (kWh per capita), provided by Energy Information Administration (EIA) • sample: 116 developing countries (excl. 21 transition countries as defined by IMF 2000) • period: 1980-2009 Birte Pohl – Renewable Energy Technology Adoption in DCs

  10. Data Descriptive Statistics on Renewable Energy Production, 1980-2009 Table 2: Per Capita Generation and Share of Aggregated Non-Hydropower, Biomass, Geothermal, Solar, and Wind Data Source: EIA. Birte Pohl – Renewable Energy Technology Adoption in DCs

  11. Data What drives the adoption of non-hydropower technology to produce electricity in DCs? • level of economic development (≈ energy demand) • policies • substitutes and opportunity costs • general drivers of technology adoption • governance and institutions Birte Pohl – Renewable Energy Technology Adoption in DCs

  12. Data Focus: Policies • renewable energy policy targets for power generation: biomass, geothermal, solar, wind, multiple renewable energy • sector: electricity • policy types: • economic instruments • policy support • regulatory instruments • research, development and deployment • information and education • voluntary approaches Data Source: IEA/IRENA Global Renewable Energy Policies and Measures Database Birte Pohl – Renewable Energy Technology Adoption in DCs

  13. Data Descriptive Statistics on Control Variables, 1980-2009 Data Sources: EIA, World Bank, IEA/IRENA, Kaufmann et al. Birte Pohl – Renewable Energy Technology Adoption in DCs

  14. Econometric Model & Methodology General Model • regression analysis, level and log specification • Fixed Effects • exclusion of outliers based on standardized residuals of first specification (1% level ≈ 2.58) Birte Pohl – Renewable Energy Technology Adoption in DCs

  15. Results: Level Specification Birte Pohl – Renewable Energy Technology Adoption in DCs

  17. Results: Log Specification Birte Pohl – Renewable Energy Technology Adoption in DCs

  18. Results: Log Specification Birte Pohl – Renewable Energy Technology Adoption in DCs

  19. Results: Other Specifications regression using biomass, geothermal solar, and wind (kWh per capita) as dependent variables • biomass: negative association for biomass policy (but data includes only two countries with such a policy); positive correlation with multiple policies • geothermal: positive, significant effect of geothermal policies • solar: no association at all • wind: positive, significant association with wind and multiple policies Birte Pohl – Renewable Energy Technology Adoption in DCs

  20. Summary of Findings • richer countries (with higher energy demand) generally invest more in non-hydropower • renewable energy policies, especially for wind power and those that target multiple renewable energy sources, seem to support investments in non-hydropower • countries that have higher shares of hydropower electricity less often invest in non-hydropower • positive association between non-hydropower generation and open trade markets • shortcomings: indirect approach, not all policies included, general technology adoption measures are not specific to the renewable energy sector Birte Pohl – Renewable Energy Technology Adoption in DCs

  21. Policy Implications and Conclusions • making countries switch to renewable energy technology is likely to require deliberate concerted efforts and context-specific policies • some policies seem to be effective • spillovers effects may be important Birte Pohl – Renewable Energy Technology Adoption in DCs

  24. Stylized Facts Renewable Energy in DCs Hydropower • wide-spread adoption: generated by 80% of all DCs in sample • average share of total electricity (2009): 38% (14% weighted with total country electricity production) Non-hydropower (biomass, geothermal, solar, and wind) • generated by about 44% of DCs in sample • average share of total electricity (2009): 1.6% • most important: biomass, geothermal • less common: wind, solar Data Source: EIA Birte Pohl – Renewable Energy Technology Adoption in DCs
