42 Energie Durable pour Tous

43 © The Energy Resource Institute Sustainable Energy for All Energie Durable pour Tous L’énergie transforme nos vies, nos économies & notre planète.

44 Energie Durable pour Tous D’ici à 2030, 3 objectifs 1.Accès à l’énergie moderne pour tous 2.Doubler l’efficacité énergétique 3.Doubler la part des énergies renouvelables

45 43 Renewable Energy in the World RE supplied an estimated 17% of global final energy consumption

46 Top RE Countries in 2012  Germany continues to lead in Europe and to be in the forefront globally, remaining among the top users of many renewable technologies for power, heating, and transport.  China ended 2011 with more renewable power capacity than any other country, with an estimated 282 GW; one-quarter of this total (70 GW) was non-hydro.

47 45

48 46  Renewables accounted for nearly half of the estimated 208 GW of new electric capacity installed in 2011  Renewable electric power capacity worldwide reached 1,360 GW (+8%) in 2011  Renewable energy comprised more than 25% of global power generation capacity  20.3% of global electricity was produced from renewable energy Global Market Overview – Power Markets

49 47  RE used in form of electricity, hydrogen, biogas, liquid biofuels. Liquid biofuels provided 3% of global road transport fuel in  Electric transport is being tied directly with renewable energy through policy directives in many countries.  Johannesburg, South Africa introduced 25 ethanol buses into its public transportation fleet during 2011 Global Market Overview - Transport

50 48

51 49  25GW of new hydropower was added in 2011, increasing capacity by nearly 3%, bringing installed capacity to 970GW  Globally hydropower generated 3,400TW h of electricity in China alone produced 663TWh followed by Brazil (450TWh)  In late 2011, Burundi, Rwanda, and Tanzania announced plans to build a 90MW hydropower plant, with financing expected from the World Bank and AfDB  South Africa is expected to have 1332MW of pumped storage facility by Hydropower

52 50 Solar Power

53 51 Solar Power  30GW of new solar PV capacity came into being in 2011  460 MW of Concentrating Solar Power installed in 2011 bringing the total installed capacity to MW

54 52

55 53 Wind Power  In 2011, 40GW of wind power capacity was installed, increasing the total to 238GW.  Annual growth rate of cumulative wind power capacity between averaged at 26%  Wind power accounted for 30% of the total new renewable energy capacity

56 54 Wind Power

57 55

58 Biomass Energy  Biomass energy accounted for over 10% of global primary energy supply in 2011  The present global demand for biomass is 53EJ, mainly used for heating, cooking and industrial applications  Liquid biofuels production grew rapidly at 17% for ethanol and 27% for biodiesel  Most sugar producing countries in Africa generate power and heat with bagasse-based combined heat and power plants. Grid connected CHP exists in Kenya, Mauritius, Tanzania, Uganda and Zimbabwe

59 57 Geothermal Energy

60 58 Geothermal Energy  205 TW h (738PJ) of district heat and electricity was provided by geothermal resources in 2011  Heat output from geothermal sources grew at 100% p.a. from ; reaching 489PJ in 2011  Geothermal power became more attractive due to flexibility offered by new technologies such as flash plants combined with binary bottoming cycles for increased efficiency  Geothermal Power has taken hold in East Africa’s Rift Valley. Drought in the region has increased interest on geothermal to reduce reliability on hydropower

61 59 Industry Trends

62 60 Industry Trends

63 61 Industry Trends  RE industry saw continued growth in manufacturing, sales and installation  Cost reductions (especially in PV and onshore wind) contributed to growth  Changing policy landscape in many countries  industry uncertainties, declining policy support, international financial crisis and barriers to trade  Worldwide jobs in renewable energy industries exceeded 5 million in 2011; clustered primarily in bioenergy and solar industries  Green power markets are emerging in South Africa, with at least one company providing green power to retail customers in South Africa

64 62 Investment Flows

65 63 Investment Flows  Total global investment in RE jumped in 2011to a record of $257 billion, up 17% from 2010 (15 % for Asia Oceania region).  This is 6 times the level of investment in 2004 and 94% more than the total investment in RE in  Despite the rise in investment, the rate of growth of investment was below the 37% rise in investment from 2009 to  Total investment in the RE sector in the Middle East and Africa combined was USD 4.9 Billion.

66 Investment Flows  The top 5 countries for total investment in 2011: China, USA, Germany, Italy and India.  RE Investment in China went up by 17% in 2011  Investment in RE in USA made a significant leap of 57% in  Investment in Germany (excluding R&D) dipped 12% from the 2010 levels  Investment in RE in India went up by 62% in 2011  relative share of total global investment of developing countries slip back :  USD 89 billion of new investment in 2011 in developing countries  USD 168 billion in developed countries

67 65 Policy Landscape

68 66 Policy Landscape  Targets in at least 118 countries up from the 96 reported in previous year; more than half are developing countries  Some setbacks resulting from a lack of long- term policy certainty and stability in many countries  South Africa introduced a new 20 year plan calling for renewables to account for 42% of all new capacity installed up to 2030

69 67 Policy Landscape  Renewable power generation policies remain the most common type of support policy, in particular Feed-in- tariffs (FIT) and renewable portfolio standards (RPS)  FIT policies were in place in at least 65 countries and 27 states worldwide by early  Policies to promote renewable heating and cooling expanded.  Almost two-thirds of the world’s largest cities had adopted climate change action plans by the end of 2011, with more than half of them planning to increase their uptake of renewable energy.

70 68

71 69  2.6 billion people still employed traditional cookstoves and open fires for heating and cooking in 2011  UN Secretary General’s goal: Global action to achieve universal access to modern energy services by 2030  In order to achieve universal access for all, current global investments on energy access of annual 9 billion USD need to be increased to 48 billion USD  Lower prices of renewable energy technology is allowing manufacturers to diversify into emerging markets  Large numbers of actors and programmes, with limited coordination, makes impact assessment and data collection a big challenge Energy Access

72 Electricity Access by Region

73 71 Rural Renewable Energy in Africa  Africa : lowest rates of access to modern energy services  More than 650 million people rely on using traditional biomass for cooking  Ghana is the frontrunner with an electrification rate of 72% and aims for universal energy access by 2020  Most renewable energy projects being implemented in Africa are off-grid (though grid connected renewable energy necessary to attract investment)  550,000 improved cookstoves have been disseminated in Benin, Burkina Faso, Burundi, Ethiopia, Kenya, Senegal and Uganda since 2009

74 72 Enabling Framework Right policy framework Increased productivity & growth Creation of jobs Improved public health Enhanced energy security, more stable climate

75 Kombikraftwerk: almost 100 % verified in real time on one year Possible potential to add: DSM (kW and kWh), Hydro, offshore wind, solid biomass, geothermal power, ocean energy
