ADB FINESSE Training Course on Renewable Energy & Energy Efficiency for Poverty Reduction 12 MDGs and PRSPs & CSPs Bottom 40% is target of Millennium Development Goals (MDGs) – central mission of development community Trouble with MDGs = trouble with PRSPs (Poverty Reduction Strategy Papers) and CSPs (Country Strategy Papers) Trouble with PRSPs & CSPs = less $ from Treasury & development partners
13
ADB FINESSE Training Course on Renewable Energy & Energy Efficiency for Poverty Reduction 13 Emphasis on Conventional Energy Options Higher proportion of funding allocated to conventional energy sector - large- scale hydro and petroleum Ethiopia: Virtually entire energy budget allocated to conventional large scale investments Smaller scale renewables largely left out (even dominant biomass is ignored) Results – contributes to low levels of access to modern energy which, in turn, contribute to increased poverty Note: Not that conventional energy is bad, it just takes long to reach the poor

ADB FINESSE Training Course on Renewable Energy & Energy Efficiency for Poverty Reduction 21 Renewed Interest in Renewables Unsatisfactory performance of conventional energy sector (high cost and unreliable due to drought) Unreliability of power supply (11,000 interruptions in Kenya every month) & high system losses (over 20%) Recent 3-4 hour/day power cuts in Ethiopia Increasing oil prices compounded by lower export earnings Climate Change Convention Johannesburg WSSD Summit 2002 - 10% renewable energy target G8 Initiative, Renewables 2004 Bonn Conference & CSD Link of poverty alleviation and sustainable development CEDIF
22
ADB FINESSE Training Course on Renewable Energy & Energy Efficiency for Poverty Reduction 22 Benefits of Renewables Response option for drought related power deficits Reduced fossil fuel imports Opportunities for income generation and poverty alleviation Opportunities for independent technology development Environment friendly For technical and financial reasons, renewables are best option for rural areas
23
ADB FINESSE Training Course on Renewable Energy & Energy Efficiency for Poverty Reduction 23 Contribution of Renewable in East and Horn of Africa Small Scale Renewables - Directly contribute to poverty alleviation Solar Small scale biomass Wind Small hydro Mechanical applications Medium Scale Renewables - Important for electricity sector, indirect impact on poverty alleviation Geothermal and Cogeneration
24
ADB FINESSE Training Course on Renewable Energy & Energy Efficiency for Poverty Reduction 24 Small Scale Renewables for Poverty Alleviation Low cost but more efficient biomass-based combustion technologies (e.g. improved cookstoves for both household and institutional applications, efficient charcoal kilns, brick making kilns, fish smokers, tea dryers and wood dryers). Pico and micro hydro for shaft power that can be used to process agricultural produce, increase its value and pump water.
25
ADB FINESSE Training Course on Renewable Energy & Energy Efficiency for Poverty Reduction 25 Small Scale Renewables for Poverty Alleviation Ram pumps for irrigation, which increase agricultural outputs thus generating additional income for poor rural farmers Solar dryers that can lower post-harvest losses and enable the rural farmers market their produce when prices are higher Solar water pasteurizers that provide clean potable water and reduce water borne diseases, which translates to increased availability of labour and thus increases agricultural output Solar PV for remote rural dispensaries
26
ADB FINESSE Training Course on Renewable Energy & Energy Efficiency for Poverty Reduction 26 Small Scale Renewables - Impact on food production Water pumping/lifting /Irrigation wind technology mechanical technologies - treadle pumps, ram pumps Agro-processing pico/micro and small hydro solar dryers Affordable to small scale farmers Lead to higher agricultural yields Significant impact on reduced incidence of food shortages
27
ADB FINESSE Training Course on Renewable Energy & Energy Efficiency for Poverty Reduction 27 Case Study: Money Maker Water Pump Simple, low-cost pumping technologies for irrigation and water supply Use in irrigation increases productivity and incomes of rural farmers by over ten- fold Farmers able to grow a wider range of crops, including high value vegetables and fruits 24,000 in use by poor farmers 16, 000 new jobs created 70% of pumps managed by women 4 manufacturers in the region
28
ADB FINESSE Training Course on Renewable Energy & Energy Efficiency for Poverty Reduction 28 Robust Self Sustaining Small Scale Renewable Industry: <1% of Electricity Bill
29
ADB FINESSE Training Course on Renewable Energy & Energy Efficiency for Poverty Reduction 29 Co-generation in Mauritius Substantial potential in agro-based industries, e.g. sugar, paper and pulp, wood and rice industries Promising developments in Uganda, Kenya and Tanzania UNEP/GEF Regional co-generation initiative Long-term, focused & specialized Successful in Mauritius (40% of power supply of which 25% bagasse) Equitable sharing of revenue from cogeneration ensures even smallest low-income farmer gets a portion of revenue
30
ADB FINESSE Training Course on Renewable Energy & Energy Efficiency for Poverty Reduction 30 Cogeneration in Sugar Industries Attractive Medium-Sized Option Could be replicated across all agro-industries Wood/timber, pulp and paper Coffee, tea, cocoa, tobacco, etc Important option as agriculture and agro-industries account for close to 50% of sub-Saharan Africa’s GDP and over 70% of employment
31
ADB FINESSE Training Course on Renewable Energy & Energy Efficiency for Poverty Reduction 31 Benefits of Co-generation Cost-competitive Local resource (security of supply) and strengthens system balance Attractive job generation (at the sugar cane plantation level) and enterprise creation potential (local technology development) Strengthens sugar sector (applicable to most agro-industrial and forestry sectors) Revenue can trickle down to low income small holder farmers - Mauritus example of revenue sharing Incremental and modular - can start small (1 or 2MW investment and then grow incrementally to 50-70MW installations) which lowers initial risks and facilitates local participation
32
ADB FINESSE Training Course on Renewable Energy & Energy Efficiency for Poverty Reduction 32 Geothermal - Medium Scale Option Significant potential along the great Rift Valley (9,000MW - for steam/hot water only) About 1% harnessed in Africa, largely in Kenya Potential for grid-connected electricity generation from geothermal also in Ethiopia, Tanzania and Uganda Significant potential for thermal use of geothermal energy
33
ADB FINESSE Training Course on Renewable Energy & Energy Efficiency for Poverty Reduction 33 Geothermal - Medium Scale Option
34
ADB FINESSE Training Course on Renewable Energy & Energy Efficiency for Poverty Reduction 34 Benefits of Geothermal Energy Security of supply 100% availability - not affected by climatic changes e.g. drought Cost competitive - least cost power development option for Kenya Attractive heat applications potential Job and enterprise creation Est. 10 jobs/MW - Kenya’s 2,000MW potential could equal 20,000 jobs Technology development - Kenya offering technical support to neighbouring countries (& in some cases, industrialized countries !)
