A Gestão Energética Descentralizada é uma forma de gestão dos recursos energéticos cujas primeiras publicações referentes ao tema datam dos anos 1980, no entanto, foi verificado um crescimento do desenvolvimento de estudos e aplicações do conceito na prática de forma substancial somente em tempos recentes (anos 2000). A Gestão Energética Descentralizada é tratada sob uma infinidade de termos e conceitos, e também pode ser aplicada com graus diferentes de descentralização como em vilas, quarteirões, bairros, distritos e estados. Tal conceito está fortemente atrelado ao combate das emissões de Gases de Efeito Estufa, busca pela inserção das fontes de energia renováveis nas matrizes, conservação de energia e eficiência energética, e pela associação entre planejamento urbano, ou das cidades, ao dos sistemas energéticos. Ainda, cabe destacar que nesse modelo de gestão descentralizado- a participação popular e o engajamento dos cidadãos nos processos decisórios e na busca por cidades sustentáveis veem sendo colocado, por muitos pesquisadores do tema, como requisitos indispensáveis ao seu adequado funcionamento. Esta dissertação tem como foco de pesquisa a Gestão Energética Descentralizada em âmbito municipal e seu desenvolvimento nas cidades do Brasil. Dessa forma...

China is short of clean energy, particularly conventional natural gas. The proven per capital natural gas reserve is only 1/12th of the world average. However, China has large coal bed methane (CBM) resources with development potential which can be recovered from surface boreholes independent of mining and in advance of mining, and also captured as a part of underground coal mining operations. However, in order to meet its targets, the government must improve the administrative framework for CBM resource management, introduce more effective CBM or coal mine methane (CMM) development incentives, raise the technical capacity of the mining sector, expand gas pipeline infrastructure and promote gas markets in coal mining areas. In order to significantly reduce methane emission from coal mines and better exploit the gas recoverable from coal seams, the government should introduce measures to: strengthen the CBM/CMM policy, legal and regulatory framework to improve resource management; improve CMM availability and quality so more can be utilized; enhance incentives to promote expansion of CBM/CMM exploitation and destruction of surplus drained CMM; and Promote development of regional development strategies to take advantage of specific local advantages.

In 1993 the Board of the World Bank endorsed a Water Resources Management Policy Paper (WRMPP). In that paper, and in this Strategy, water resources management comprises the institutional framework (legal, regulatory and organizational roles), management instruments (regulatory and financial), and the development, maintenance and operation of infrastructure (including water storage structures and conveyance, wastewater treatment, and watershed protection). The 1993 Policy Paper reflected the broad global consensus that was forged during the Rio Earth Summit of 1992. This consensus stated that modern water resources management should be based on three fundamental principles (known as the Dublin Principles). First is the ecological principle which argues that independent management of water by different water-using sectors is not appropriate, that the river basin should be the unit of analysis, that land and water need to be managed together and that much greater attention needs to be paid to the environment. Second is the institutional principle...

The objective of this paper is to examine the challenges in the water sector faced by Armenia today, and outline options for management and allocation of its water resources in the future, considering the need for a stable, transparent apublic sector management framework and sustainable resource use for long-term private investment and job creation, and for appropriate balances among water uses for domestic, industrial, agriculture, electricity generation, watershed protection, and ecological purposes. The report builds on the recommendations of the Integrated Water Resources Management Planning (IWRMP) Study, which was supported by the World Bank, financed by the Government of Netherlands, and completed in 2001. The report also builds on experience with project implementation to date in water-related sectors. The report suggests that a water management strategy that focuses on rehabilitation and reduction of water losses, and balances for drinking, irrigation, hydropower, and environmental use is likely to have the highest welfare gains.

In declaring 2012 the international year of sustainable energy for all, the United Nations (UN) general assembly (2011) established at the personal initiative of the UN secretary general- three global objectives to be accomplished by 2030. Those goals are to ensure universal access to modern energy services (including electricity and clean, modern cooking solutions), to double the global rate of improvement in energy efficiency, and to double the share of renewable energy in the global energy mix. Some 70 countries have formally embraced the Sustainable Energy for All (SE4ALL) initiative, while numerous corporations and agencies have pledged tens of billions of dollars to achieve its objectives. As 2012 drew to a close, the UN general assembly announced a decade of sustainable energy for all stretching from 2014 to 2024. Sustaining momentum for the achievement of the SE4ALL objectives will require a means of charting global progress over the years leading to 2030. Construction of the necessary framework has been coordinated by the World Bank and Energy Sector Management Assistance Program (ESMAP) and the International Energy Agency (IEA)...

The tradeoffs between energy and water have been gaining international attention in recent years as demand for both resources mount and governments continue to struggle to ensure reliable supply to meet sectoral needs. As almost all energy generation processes require significant amounts of water, and water requires energy for treatment and transport, these two resources are inextricably linked. This relationship is the energy-water nexus. Section one of this paper examines the existing models, literature, and management frameworks on the nexus, as it seeks to determine what gaps exist. Section two describes the water demands of power generation in order to identify potential areas of future uncertainty and delineate areas where integrated energy-water management may improve the reliability of operating power plants and the viability of schemes. Finally, section three describes possible solutions that may alleviate challenges resulting from the link between energy and water by improving energy efficiency and integrating water resources management into energy planning.

About one-third of global energy is consumed in residential, public, and commercial buildings (collectively referred to as buildings), where it is used for space heating, cooling, ventilating, lighting, cooking, water heating, refrigerating, and operating electric and mechanical devices. Global energy use in buildings is expected to grow as cities in developing countries continue to modernize and per capita income levels continue to increase. Because of their high energy consumption, residential, public, and commercial buildings also offer unparalleled opportunities for energy savings. According to the International Energy Agency, buildings account for some 41 percent of global energy savings potential by 2035, compared with the industrial sector (24 percent) and the transport sector (21 percent). This guidance note outlines how cities can tap into a wide array of proven technologies, policies, and financing mechanisms to improve energy efficiency and capture cost-effective energy savings in buildings. It offers city leaders advice on how to get started in introducing energy efficiency measures...

To ensure sustainable and optimal use of its common property natural resources, Mexico will need to strengthen its focus on enhancing stewardship in three key sectors-forests, water, and energy resources. The key objectives include the following: 1) identifying options that would contribute to Mexico's climate agenda and build social resilience through forest management; 2) ensuring economically efficient and environmentally and socially sustainable water management to promote 'green' growth in the context of water scarcity and climate uncertainty; and 3) assessing the impacts of declining oil and gas reserves and the role of renewable energy as an alternative and cleaner source. Forests can play an important role in mitigating and adapting to climate change. Reducing Emissions from Deforestation and Forest Degradation (REDD+) and other forest-related activities could account for almost 20 percent of reductions in greenhouse gas emissions that Mexico could achieve by 2030. Although much remains to be done...

The world's urban population is expected to increase by about 2.7 billion by 2050.Virtually all of the increased population will be in developing countries, leading to massive needs for new and improved housing and urban infrastructures (UNDESA 2012). The planning and design of these new developments will reshape or create new urban landscapes with significant implications for energy consumption, infrastructure costs, as well as the livability and social and economic resilience of cities. Studies of cities around the world indicate that a city's livability and its level of energy use are closely linked to its physical form, namely the spatial distribution and dimensions of buildings, streets, and parks, as well as the spatial coordination of residences, jobs, social services, and environmental amenities.

Energy efficiency can improve fiscal balances, stimulate growth and competitiveness, strengthen energy security, and reduce the energy burden of the poor. It also can enhance the quality of life by improving energy products and services, reducing pollution, and reallocating savings from energy to social services and other welfare enhancements. From a long-term perspective, energy efficiency preserves energy resources for future generations and mitigates climate change. Most governments in the region consider energy efficiency as a priority issue, although for different reasons. The key issue for many is the weight of energy subsidies in fiscal balances; for others, it is the vulnerability of the economy to swings in hydrocarbon prices and the risk of losing competitiveness; and for still others, it is concern about generating enough financing for energy investments and satisfying the energy demand of their fast-growing economies. These factors have prompted governments to renew their efforts to improve energy efficiency. This report explores opportunities to boost energy efficiency in the Middle East and North Africa and secure a sustainable energy future for the region. It explores governments' growing concern about the burden of energy subsidies and identifies opportunities to improve efficiency...

The aim of the scoping study was to gain an understanding of the productive activities slum dwellers engage in that rely on energy services and the potentials and challenges of slums in Ghana regarding access to modern energy services and income generation from productive activities. The objective of the ESMED-EAfUP (Energy Sector Management Assistance Program - ESMAP/SME Development - Energy Access for the Urban Poor) programme is 'to create and sustain a network of energy practitioners to support development of Micro, Small and Medium Enterprises (MSME) as users and providers of modern energy services for slum upgrading programs.'. Using ability to adopt safer and modern energy forms as a criterion in assessing the effective deployment of safer and modern energy forms, the study concluded that the high propensity to save is an opportunity for their deployment if they can be sensitized about the benefits of using modern energy forms, which many of the slum dwellers are not aware of. Most enterprise owners could also capitalize on the credit policies of the financial institutions they saved with to adopt the modern energy forms. Lack of education and limited awareness about the benefits of using clean...

China expects its gross domestic product in 2020 to be four times that of 2000. Limits on energy resources and China's environmental needs require that electricity use grow at a much lower rate than the economy. Demand-side management (DSM) is a critical component of China's sustainable development. It is a set of tools and practices taken by utilities to influence the amount and/or timing of customers' energy demand in order to utilize scarce electric supply resources most efficiently. DSM is a proven method of meeting economic goals in an environmentally sustainable way, and it is also a fast and effective way to address power shortages. This report reviews China's experience with DSM, explores the barriers to and the potential for new demand-side investment, and examines successful DSM strategies in other countries. It suggests the near-and long-term regulatory and government policies needed to support substantial new investment in comprehensive, cost-effective programs for end-use efficiency and load management.

Cities represent a major contributor of greenhouse gas (GHG) emissions. According to the United Nations Population Fund,1 half of the world's population now lives in cities and is responsible for 75% of global energy use and GHG emissions. Since the world's population will continue to grow, and rapid urbanization will continue particularly in the developing world, tackling climate change issues in the urban context will be essential. In response to these challenges, the World Bank's Energy Sector Management Assistance Program (ESMAP), in cooperation with the Bank?s Finance Economics and Urban Department (FEU), has launched an Energy Efficient Cities Initiative, which is designed to help mainstream and scale-up sustainable energy and climate change mitigation actions and investments in the urban context. The first activity proposed under this Initiative is the Energy Efficient Cities Practitioners Roundtable, a facilitated discussion cohosted by ESMAP and FEU. The purpose of this event was to bring together client cities and partner organizations to investigate ongoing initiatives and programs to support cities' sustainable energy goals needs and develop an Energy Efficient Cities Action Plan that will outline a vision and subsequent actions to be taken under the Initiative. The event took place at the Washington DC offices of the World Bank...

Há algum tempo, a energia elétrica tem sido pensada como um fator de fomento ao desenvolvimento de regiões carentes. No entanto, a experiência tem mostrado que, embora seja realmente necessária, a presença da energia elétrica, por si só não é suficiente para alcançar tal objetivo. Neste contexto, o presente trabalho aborda a disponibilização da energia elétrica de forma integrada em um cenário mais amplo, o da infra-estrutura, abrangendo o Transporte, a Água e Saneamento, o Tratamento do Lixo e as Telecomunicações, com vistas a criar uma base sólida para alavancar o desenvolvimento. Para tanto, propõe a abordagem da Gestão Integrada de Recursos – GIR, que é balizada pelo equilíbrio entre os aspectos econômico, social e ambiental dos empreendimentos, visando a provisão de infra-estrutura com vistas ao desenvolvimento sustentável de regiões carentes. Esta metodologia, desenvolvida no contexto de uma visão abrangente e integrada da infra-estrutura, permite a identificação de sinergias e potencialidades entre os seus componentes, bem como de possíveis parcerias entre os envolvidos. Dessa forma espera-se estabelecer vantagens econômicas, sociais e ambientais na provisão de infra-estrutura pelo setor privado sob a ação do Estado...

The use of distributed energy resources, based on natural intermittent power sources, like wind generation, in power systems imposes the development of new adequate operation management and control methodologies. A short-term Energy Resource Management (ERM) methodology performed in two phases is proposed in this paper. The first one addresses the day-ahead ERM scheduling and the second one deals with the five-minute ahead ERM scheduling. The ERM scheduling is a complex optimization problem due to the high quantity of variables and constraints. In this paper the main goal is to minimize the operation costs from the point of view of a virtual power player that manages the network and the existing resources. The optimization problem is solved by a deterministic mixedinteger non-linear programming approach. A case study considering a distribution network with 33 bus, 66 distributed generation, 32 loads with demand response contracts and 7 storage units and 1000 electric vehicles has been implemented in a simulator developed in the field of the presented work, in order to validate the proposed short-term ERM methodology considering the dynamic power system behavior.

The intensive use of distributed generation based on renewable resources increases the complexity of power systems management, particularly the short-term scheduling. Demand response, storage units and electric and plug-in hybrid vehicles also pose new challenges to the short-term scheduling. However, these distributed energy resources can contribute significantly to turn the shortterm scheduling more efficient and effective improving the power system reliability. This paper proposes a short-term scheduling methodology based on two distinct time horizons: hour-ahead scheduling, and real-time scheduling considering the point of view of one aggregator agent. In each scheduling process, it is necessary to update the generation and consumption operation, and the storage and electric vehicles status. Besides the new operation condition, more accurate forecast values of wind generation and consumption are available, for the resulting of short-term and very short-term methods. In this paper, the aggregator has the main goal of maximizing his profits while, fulfilling the established contracts with the aggregated and external players.

The major role tropical forests play in biodiversity and climate change has led the world to search for effective ways to slow down deforestation. Community forest management (CFM) is an example of the broader concept of community-based natural resources management (CBNRM). As part of the decentralization policy in many countries, mainly in Africa and Asia, CFM was expected to promote: (i) a more effective stewardship of the resources by involving the local communities in the management of the resources, and (ii) a more locally-driven development with them tapping most of the derived benefits. The precursors of CBNRM and CFM in Madagascar are the centrally-led compensation-based mechanisms to conservation. Madagascar is one of the first countries in the southern hemisphere to have put in place a legal framework for CBNRM and CFM. The CBNRM implementation process starts with the creation of a local natural resources management group. The government has identified the protection of natural capital and the harnessing of its value as a key pillar in its national development plan for 2015-2019. The plan identifies poor governance as a major constraint to achieving the country’s development objectives. It puts strong emphasis on the roles of both natural capital and the necessity for a more inclusive economy to achieve sustainable development. This report will help the Bank take stock of the nearly two-decades of implementation of the national environmental action plan and provide nation-wide facts that will inform future investment in renewable natural resources management...
