O uso de informações derivadas de satélites tem ganhado cada vez mais espaço em áreas em que antes não havia utilização, e isso se deve muito aos avanços tecnológicos de sensores e componentes que são instalados nestes equipamentos lançados em órbita. Na agricultura não foi diferente, este segmento da cadeia produtiva tão importante para economia brasileira e mundial tem se aproveitado desses avanços para aperfeiçoar suas técnicas e práticas de manejo de cultivos em diversas formas, sendo uma delas o manejo de irrigação de culturas. Uma das formas de realização do manejo de irrigação é através do balanço hídrico, que tem como principal componente de entrada a utilização de dados meteorológicos para cálculo da evapotranspiração de referencia (ETo), em que na maioria das situações são obtidas através de dados disponibilizados por instituições que possuem estações meteorológicas convencionais (EMC) ou através de estações automáticas (EMA) instaladas nas propriedades rurais. A limitação é que estes métodos, apesar de serem confiáveis, são onerosos economicamente e depende de pessoal treinado para coletar estas informações, no caso da EMC, e ainda podem não estar próximo a área agrícola de aplicação. Em alternativa a este modo, a plataforma NASAPOWER vem ganhando destaque em alguns estudos pela disponibilização de dados meteorológicos diários derivados de satélite para qualquer região do globo. Desta forma, este trabalho teve como objetivo avaliar o comportamento dos dados meteorológicos disponibilizados pelo NASAPOWER em relação aos dados fornecidos pelo INMET e coletados através de EMC na aplicação do manejo de irrigação em diversas culturas e regiões do Brasil, fazendo uso da equação de Penman-Moteith FAO como obtenção da ETo. O estudo foi constituído através de simulações de cultivo das principais culturas de valor econômico usadas em diferentes regiões do país, tendo informações de entrada como o coeficiente de cultivo ao longo do ciclo, determinação da água facilmente disponível (AFD) local, tempo de cultivo, e duas bases de dados meteorológicos com período de 31 anos. Os resultados de complementação hídrica com base na plataforma NASAPOWER se mostraram bem ajustados na maioria das simulações, sendo recomendado sua utilização na cultura do algodão na região de Luís Eduardo Magalhães, da soja em Cruz Alta, do milho grão em Balsas e da laranja em Araraquara. Não foi recomendado sua utilização para a cana-de-açúcar em Uberaba e o feijão em Primavera do Leste. Enquanto que para o milho doce em Unaí, arroz em Uruguaiana, cana-de-açúcar em Rio Verde e café em Araguari há uma recomendação com ressalvas. De maneira geral, a avaliação de recomendação de irrigação para as safras avaliadas obteve um coeficiente de correlação (r) de 0,95, coeficiente de determinação (R2) de 0,95, raiz quadrada do erro médio (RMSE) de 115 mm, erro médio absoluto (MAE) de 85 mm e um coeficiente de Willmott (d) de 0,96. The use of information derived from satellites has been gaining space in areas where previously there was no use. This is incrising due to the technological advances in sensors and components that are installed in equipment launched in orbit. In agriculture, it was no different, this segment of the productive chain so important for the Brazilian and world economy has been taking advantage of these to improve its techniques and practices of crop management in several ways, where one is crop irrigation management. One of the ways of carrying out irrigation management is through the water balance, whose main input component is the use of meteorological data to calculate reference evapotranspiration (ETo). The weather data are obtained through institutions in the most cases, which have conventional weather stations (EMC) or automatic stations (EMA) installed in rural properties. The problem is that these methods, despite being reliable, are economically costly and depends on trained personnel to collect this information in the case of EMC and can still not be close to the agricultural application area. As an alternative to this mode, the NASAPOWER platform has been gaining prominence in some studies due to the availability of daily meteorological data derived from satellite for any region of the globe. Thus, this work aimed to evaluate the behavior of meteorological data provided by NASAPOWER in relation to the data provided by INMET, collected through EMC, in the application of irrigation management in different cultures and regions in Brazil, using the Penman-Moteith equation - FAO to obtain ETo. The study considered simulations of the main crops of economic value used in different regions of the country, having input information of cultivation coefficient throughout the cycle, determination of the local available water to the crop, cultivation period, and two bases of meteorological data with a period of 31 years. The results of irrigation requirement based on the NASAPOWER platform proved to be adjusted in most simulations with used EMC, and its use in cotton culture in the Luís Eduardo Magalhães region, soybean in Cruz Alta, corn in Balsas and orange in Araraquara are recommended. Its use was not recommended for sugar cane in Uberaba and beans in Primavera do Leste. While for sweet corn in Unaí, rice in Uruguaiana, sugar cane in Rio Verde and coffee in Araguari, there is a recommendation with reservations. In general, the evaluation of irrigation for all evaluated crops obtained a correlation coefficient (r) of 0.95, determination coefficient (R2) of 0.95, square root of the average error (RMSE) of 115 mm, mean absolute error (MAE) of 85 mm and a Willmott coefficient (d) of 0.96.

Based on the World Bank’s own extensive global experience and drawing upon international expertise from leading specialists and practitioners, this report presents a comparative assessment of various approaches that have been applied around the world, with varying degrees of success, to mitigate resource risks and catalyze investments in developing the geothermal sector. It provides a framework that can help decision makers identify suitable approaches that are commensurate with development goals, funding capacity, implementation capabilities, and other circumstances specific to the context in a given country. Geothermal presents an opportunity for many countries to diversify their power generation mix in a sustainable way since it is an environmentally friendly, clean energy source that can reliably produce baseload power on a 24 by 7 basis. Despite over 100 years of development and an estimated global potential of 70 - 80 gigawatts (GW), only about 15 percent of the known geothermal reserves are presently exploited and producing electricity. While there are many reasons, in various countries, for the slow pace of geothermal development, one widely recognized and unique obstacle that is applicable worldwide is the high resource risk during the early stages of the geothermal development process. As a result, it is difficult to mobilize the early-stage investments, especially through the private sector.

This Energy Sector Policy Note is intended to support the Government of Mozambique in determining priorities for policy decisions with the aim of delivering efficiently produced, technically and financially sustainable electricity supply to the Mozambican population. To support the development of recommendations, this Note includes simulation analysis based on the current finances of the sector. Electricidade de Macambique’s (EDM) corporate financial model was adapted for this work. Targets for electrification are based on discussions with government officials. EDM’s current generation pipeline and its timing was taken as a given in order to simulate investment needs and evolution of sector finances under various tariff and funding availability assumptions. The various simulations and the broader sector quantitative and qualitative discussion should support policy formulation and prioritization going forward. The power sector in Mozambique faces three key challenges: i) to provide reliable and efficient electricity supply to its customers; ii) to cope with the increase in the electricity demand from its current (and future) customer base by expanding its generation and transmission capacity; and, iii) to provide access to electricity to the vast majority of the population. The importance of the timing of new generation to export power to South Africa also points to the importance of the backbone transmission project to evacuate the power from the center of the country – thereby enabling exports. Increasing access in line with Government targets will require major investments. The Government needs to consider the trade-offs between the ambition of the access targets imposed upon EDM and the sector’s broader financial viability for carrying out operations, maintenance and investment. Relaxation of the access target so that the 50 percent target is achieved by 2030 instead of 2023 gives EDM more liquidity in the first years.

These guidelines are directed to the economic analysis of power sector policy analysis and the appraisal of power sector investment projects. The general guidance is complemented by an Annex Volume that contains relevant technical notes, a glossary, and an extended Bibliography. In this first edition, the focus of the technical notes is on grid-connected renewable energy projects. In FY16 the scope of the technical notes will be extended to cover transmission & distribution, rural electrification, off-grid, energy efficiency, and thermal projects.

The World Bank Group has committed to achieving universal access to electricity by 2030 under the Sustainable Energy for All (SE4All) initiative. This is a daunting challenge: more than 1 billion people do not have access, and another 1 billion have chronically inadequate or unreliable service. Most of those without access are poor, and the largest share is in Sub-Saharan Africa. Achieving universal access within 15 years for the low-access countries (those with under 50 percent coverage) requires a quantum leap from their present pace of 1.6 million connections per year to 14.6 million per year until 2030. The investment needed would be about $37 billion per year, including erasing generation deficits and meeting demand from economic growth. By comparison, in recent years, low-access countries received an average of $3.6 billion per year for their electricity sectors from public and private sources, including $1.5 billion per year from the World Bank Group. Development outcomes of the Bank Group’s assistance were generally favorable compared with other infrastructure sectors. However, performance in improving financial viability of country electricity sectors was below expectations. There were significant gaps in the Bank Group’s coverage of low-access countries, mostly in Sub-Saharan Africa. Median implementation time of World Bank investment projects was nine years, with time overruns attributable to inadequate project design and borrower capacity. Support for off-grid electrification was low and sporadic, with a few notable exceptions. The Bank Group’s growing non-conventional renewable energy portfolio is dealing with technology and regulatory challenges. Tracking welfare and gender impacts in World Bank projects has improved, and International Finance Corporation (IFC) has made a beginning in addressing these issues. The Bank made some significant pilot contributions to addressing the affordability of electricity connections. Collaboration grew among World Bank, IFC, and MIGA through joint projects, which helps break ground for the private sector in some high-risk and fragile countries, and supports a few large and complex projects. The scale of the SE4All challenge requires the Bank Group to reposition itself as a global solutions provider in the sector, going well beyond the confines of its own direct support for access. This evaluation points to the urgency for the Bank Group‘s energy practice to adopt a new and transformative strategy to help country clients orchestrate a national, sustained sector-level engagement for universal access. A major challenge in this effort is to deploy the Bank Group units’ individual and collective strengths beyond Bank Group–led projects and transactions to stimulate private sector investments for closing the financing gap, especially in generation, for low-access countries.

South Asian countries, facing challenges in efficiently meeting growing electricity demand, can benefit from increased cross-border electricity cooperation and trade by harnessing complementarities in electricity demand patterns, diversity in resource endowments for power generation, and gains from larger market access. The region has witnessed slow progress in expanding regional electricity cooperation and trade, and undertaking needed domestic sector reforms. Although bilateral electricity sector cooperation in the region is increasing, broader regional cooperation and trade initiatives have lagged in the face of regional barriers and domestic sector inefficiencies. Deeper electricity market reforms are not a necessity for further development of cross-border electricity trade, but limited progress in overcoming regional and domestic barriers will limit the scope of the regional market and the benefits it can provide.

With an installed capacity greater than 137 gigawatts (GWs) worldwide and annual additions of about 40 GWs in recent years, solar photovoltaic (PV) technology has become an increasingly important energy supply option. A substantial decline in the cost of solar PV power plants (80 percent reduction since 2008) has improved solar PV’s competitiveness, reducing the needs for subsidies and enabling solar to compete with other power generation options in some markets. The World Bank Group (including the International Bank for Reconstruction and Development, the International Development Association, International Finance Corporation (IFC), and the Multilateral Investment Guarantee Agency) helps client countries secure the affordable, reliable, and sustainable energy supply needed to end extreme poverty and promote shared prosperity. The approach mirrors the objectives of the sustainable energy for all initiative - achieving universal access, accelerating improvements in energy efficiency, and doubling the global share of renewable energy by 2030. The World Bank Group recognizes that each country determines its own path for achieving its energy aspirations, and that each country’s transition to a sustainable energy sector involves a unique mix of resource opportunities and challenges, prompting a different emphasis on access, efficiency, and renewable energy. The objective of this guidebook is to enhance the reader’s understanding of how to successfully develop, finance, construct, and operate utility-scale solar PV power plants. The guidebook focuses on aspects of project development that are specific to solar. From this perspective it covers all aspects of the overall project development process including site identification, plant design, energy yield, permits and licenses, contractual arrangements, and financing, giving sparser coverage to general project development basics that are not specific to solar. This guide covers the key building blocks to developing a successful utility-scale solar power project (the threshold for utility-scale depends on the market, but generally at least 5 megawatt (MW).

Yumkella recalls his own experiences in Sierra Leone to illustrate the link between energy poverty and income poverty and explains how PPPs can help.

Mitigating climate change while addressing development needs will involve a massive scale-up of investments in Renewable Energy (RE) and Energy Efficiency (EE). Most of these climate investments will come from the private sector, which will be the main driver of low-carbon growth in both developing and developed countries, provided that countries have the right investment climate for climate investment. The enabling environment for climate investment in each country depends on a variety of factors. These include macroeconomic determinants such as a functioning bureaucracy and banking system; as well as a narrower set of policy determinants such as renewable energy targets, mandatory standards, preferential power tariffs, waiver of import duties, and other fiscal incentives. While the exact mix of policies, regulations and incentives will depend on country-specific circumstances, the fact that they exist sends the right signal to climate investors, by providing them with legal certainty and lowering their costs and risks. Policies, regulations and incentives also help to level the playing field for climate investors in the face of market realities that tend to favor the continued use of carbon intense energy sources, such as support for fossil fuels and the high costs of renewable energy technologies.

This study is a product of the Africa Infrastructure Country Diagnostic (AICD), a project designed to expand the world's knowledge of physical infrastructure in Africa. Infrastructure contributed 1.8 percentage points to Cote d'Ivoire's annual per capita Gross Domestic Product (GDP) growth in the mid-2000. Raising the country's infrastructure endowment to that of the region's middle-income countries could boost annual growth by a further two percentage points per capita. Cote d'Ivoire made major strides with respect to infrastructure during the 1990s. As a result, the country has broad-reaching national backbones in the road, energy, and Information and Communication Technologies (ICT) sectors, and relatively high levels of household coverage for utility services. However, much ground was lost to conflict in the mid-2000s. Very little investment has taken place in the last fifteen years, leading to recent power shortages, the deterioration of the road network, and the deceleration of progress on safe water access. Cote d'Ivoire's most pressing challenge will be to regain the financial equilibrium needed to restore a reliable energy supply. Reestablishing the prominence of Abidjan's port will require investments in terminal capacity, as well as road and rail infrastructure upgrades on hinterland linkages. The underfunding of road maintenance must also be addressed. Another challenge lies in sanitation, as it is currently unlikely that the country will meet the associated millennium development goal. This report presents the key AICD findings for Cote d'Ivoire, allowing the country's infrastructure situation to be benchmarked against that of its African peers. A social and economic crisis in Cote d'Ivoire has crippled its growth trajectory, which had been that of a middle-income country. It will therefore be compared to low-income countries (fragile and non-fragile groups) and middle-income countries, as well as immediate regional neighbors in West Africa. The study presented several methodological issues.

In many developing countries with large rural populations and low rural electrification rates, most community health and education facilities lack access to electricity. For facilities in remote areas beyond reach of the national grid, photovoltaic's (PV) systems may offer the most practical and least-cost way to access electricity. A PV system uses predictable solar resources and has long been cost competitive with diesel generators and other alternatives. In off-grid rural primary schools and health dispensaries, for example, PV systems oftentimes are an appropriate way to run many low-power, high-value appliances and equipment, from lamps and vaccine refrigerators to water pumps, television sets, and computers. Thus, if the electricity grid is not expected to arrive in the near future or if diesel fuel is unavailable or too expensive, a PV system may offer the least-cost technology for providing electricity service. If this rapid assessment determines that PV is a viable option, it results in a brief concept for a possible project and the plan for its preparation. The project concept is discussed with stakeholders and independent specialists, including off-grid renewable energy specialists, and is adjusted as appropriate. The plan for project preparation takes into account an assessment of available information and activities to be undertaken during preparation to fill gaps and generate additional and improved data. The second phase of project development is the preparation of the PV implementation plan. This is accomplished with the assistance of several specialists, including a PV technical specialist, and involves working closely with lead organization managers and specialists, broad-based stakeholder consultations, and multiple iterations. The third phase of project development, procurements and contract management, involves securing firm financing commitments (including those for post-project recurrent costs), developing tender packages, tendering and contracting, and contract management. The fourth phase, long-term operation, is where too many projects fail. In summary, this toolkit is, at a minimum, a checklist of key issues to address in developing an institutional PV project. While it is not a technical manual, nor a substitute for using professional PV specialists to size, configure, and specify system and maintenance requirements, it offers practical operational guidance to assess, develop, and implement projects with PV systems in ways that enhance cost effective supply and sustainable post-project operations. The guidance offered herein demonstrates that the opportunities for effectively addressing the issues to establish the basis for sustainability are many.

The rapid growth of Vietnam's economy, industry, and consumption has resulted in unprecedented growth in energy demand, and its infrastructure for extracting, generating, and distributing energy is expanding to try to meet those needs. Between 2000 and 2005, total primary energy consumption in Vietnam grew 10.6 percent per year. Growth in fossil-fuel consumption was correspondingly high, with coal use growing at 14.9 percent per year, oil use at 8.2 percent per year, and natural gas use at 37 percent per year. From 2002 to 2030, Vietnam's primary energy demand is expected to grow at a rate of 4.4 percent, increasing from 42 megatons oil equivalent (MTOE) in 2002 to 142 MTOE in 2030. This note will focus on Vietnam's potential Greenhouse gas (GHG) emission reductions and possible interventions associated with resource extraction and power generation for grid electricity. Emissions from power generation in industry and transport are covered under the respective sector notes, and reduction of greenhouse gases through management of end-use demand is covered in the context of industry (as the largest energy user) in the industry sector note.

The 2005 Gleneagles G8 summit in July 2005 stimulated a concerted effort of the Multilateral Development Banks (MDBs) to broaden and accelerate programs on access to energy and climate change mitigation and adaptation through the Clean Energy Investment Framework (CEIF). At the Gleneagles summit, it was agreed that a report on the implementation of the CEIF would be prepared for the 2008 G8 (Group of Eight: Canada, France, Germany, Italy, Japan, Russia, the United Kingdom, and the United States) summit hosted by Japan. This joint report of the MDBs to the G8 summit in Hokkaido is intended to provide information on the outcomes and lessons learned under the CEIF, describe the collective MDB objectives for addressing the energy access and climate change challenges, and outline how the MDBs plan to build on the CEIF experience to date to more fully achieve these objectives. The report builds upon the 'the MDBs and the climate change agenda' report that was presented at the December 2007 Bali climate change conference. This report describes actions taken by each MDB to develop climate change strategies and programs of actions tailored to their particular client needs, based on resources and funding mechanisms currently available. Under the CEIF, the MDBs have strengthened collaboration on analytical work and programming and committed to expand this collaboration to optimize the impact of their collective actions. In addition to reporting on the status of the CEIF, this report outlines the collective ambition of the MDBs with respect to assisting the developing countries in meeting the climate change challenge, summarizes their evolving strategies designed to meet these objectives and the mechanisms through which they intend to achieve the necessary collaboration to optimize the collective impact of their climate change interventions.

The joint United Nations Development Program (UNDP) and World Bank Energy Sector Management Assistance Program (ESMAP) is a special global technical assistance partnership sponsored by the UNDP, the World Bank, and bi-lateral official donors. Established with the support of UNDP and bilateral official donors in 1983, ESMAP is managed by the World Bank. ESMAPs mission is to promote the role of energy in poverty reduction and economic growth in an environmentally responsible manner. Its work applies to low-income, emerging, and transition economies and contributes to the achievement of internationally agreed development goals. ESMAP interventions are knowledge products including free technical assistance specific studies advisory services, pilot projects, knowledge generation and dissemination, trainings; workshops and seminars, conferences and roundtables, and publications. ESMAP work is focused on three priority areas: access to modem energy for the poorest, the development of sustainable energy markets, and the promotion of environmentally sustainable energy practices. ESMAP has supported a number of energy trade programs, but so far feedback from these projects and evaluations of the knowledge gained has been limited. It was therefore decided to undertake a review ESMAPs portfolio of projects related to the international trade of energy. This review was to include not only those projects that have been completed, but also those that currently are under way, and those that are in the immediate pipeline. The review was guided by the technical advisory group to the energy trust funded programs located at the World Bank.
