1 Estimating the potential impact of a greening economy on job creation Day Month Year Green Economy Summit Sandton, 19 May 2010 Jorge Maia Head: Research & Information Industrial Development Corporation

2 Introduction to the IDC/DBSA research project 2 High expectations around green jobs: – Rapid growth sector with enormous multi-sectoral potential. – Determinant of future competitiveness. – Economic crisis imperative – one of the main solutions.  Need for greater clarity around job creating potential. Existing figures on green jobs: – High variability from one study to another - mainly sector- or technology-specific, no macro-economic estimates. – Often weak reliability / uncertainty about the sources.  Uncertainty = criticism = credibility issues. Inform optimal technology mix to meet energy demand, highlighting relative jobs potential: – Not “green jobs” in isolation, but strong employment emphasis/balance when greening the economy. – Policy trade-offs (long-term economic growth, emissions reduction, job creation, sustained competitiveness). – Acknowledge and face the various constraints. – Prioritise sectoral emphasis, sequencing policies over time.  Maximise job creation as we green the SA economy.

3 Moving away from an overwhelming dependency on fossil fuels (especially coal) for energy generation in SA, towards alternative energy sources: Mining Transport (logistics) Environmental impact such as pollution levels (air, water, soil etc.) Economic linkages (GDP, jobs, investment, etc.) Impact on output levels, investment & jobs in coal mining (expansion at slower pace, substitution in the L-T) (New investment, jobs and output through alternative energy sectors, incl. const., manufacturing, O&M.) Improvement in soil and land quality Reduced economic activity in several sectors (e.g. machinery & equipment, chemicals etc.), via linkages, due to lower coal mining production over time Improved water and air quality Increased water availability Increased economic activity due to linkages arising from expanding renewable energy sector & introduction of cleaner technologies. Potential growth of export sector associated with renewables & cleantech. Transportation of cleantech materials Transport of export coal to ports. Road usage: reduced congestion & infrastructural damage. Transportation services activity (rail & road) from coal mines to power stations Regional shifts i.t.o. investment, GDP, jobs - ve impact + ve impact Introduction to the IDC/DBSA research project (cont.)

4 Estimating the economy-wide impact Assessing the impact of introducing alternative/renewable energy sources & cleantech New investment required Demand for investment related goods and/or materials during construction phase Increased construction activity, as well as higher production activity in existing/new domestic supplying sectors (GDP, jobs, investment, etc.) Adverse BoP implications due to increased import demand for specialised goods not available in SA, particularly in the S-T, gradually +ve Cleaner energy generation/ technology application and operational phase Increased economic activity associated with cleaner energy generation / technology application, with direct impact on job creation Increased economic activity in associated industries through linkages / multiplier effects (e.g. business services, components manufacture) Adoption of “greener” technologies 4 Export potential Export potential

6 Technically, wind power has the largest RE generation potential after solar. Growth in global wind power generation capacity has been almost exponential. Some slowdown since late 2008 (with a few exceptions such as China). Significant contribution in more than 70 countries, both industrialised and emerging/ developing. Major challenges include: –Not yet competitive, although continuously improving; –Depend on available wind power, backup capacity needed; –Logistics for construction; –Grid connection. Case study – wind power generation: Growth and challenges Cumulative global wind power generation capacity 6

7 Case study – wind power generation: Potential and challenges SA’s wind power potential: Recorded potential is only moderate at best, though data is insufficient ; Potential contribution to power generation in SA may be significantly higher – improved wind atlas being developed; Potential (average speed) directly affects unit cost; Some areas in east and north Africa seem to have higher wind power potential than South Africa. Major challenges facing the domestic wind power industry: Transmission infrastructure / grid connection; Regulatory framework, progress, support ; Wind energy expected to be competitive by

8 Case study – wind power generation: Opportunities and strengths General opportunities & strengths include: Promising REFIT tariff, ‘free’ power source, little water needed. Tested technologies, improving competitiveness. Commissioning – short period, generating units separately completed. Strong investor interest – many proposed projects in pipeline, involving both global & local players. Existing manufacturing capacity, demand-driven expansion potential. New components manufacturing potential. African markets. Support from global institutions (UNDP, GEF, IFC). 8

9 Case study – wind power generation: Potential involvement of local industries Local industries: Potential capacity to contribute IndustryProductCapacity Construction & civil engineeringFoundation laying, tower erection, housingSufficient Manufacturing: Steel & metal products Glass fibre & composites Electrical equipment Machinery Towers, frames, hubs, brakes, other parts Rotor blades, nacelle housing Generators, transformers, cables, other parts Shafts, bearings, gears Very good Good Limited Electricity distributionGrid connectionGood Electricity generationOperation & maintenanceGood LogisticsTransporting mega-parts on rough terrainChallenging Local manufacturing capacity (see next slide) can be promoted through engagement with established global manufacturers. Significant opportunity exists in construction and manufacturing activities targeting other African markets with higher/good wind power potential. 9

Estimation work yet to be undertaken on: – Emissions control. – Biodiversity.  Need for substantial testing with key role players.
