Maximizing yields is opposed to the goal of minimizing the use of inputs. In the context of system rationalization, the addition of non-economic parameters in the decision making and the magnitude of eucalyptus plantation in Sao Paulo State, Brazil led to this study. The objective was to establish the flows and to evaluate the performance of energy transformations on eucalyptus production. The evaluated system presented three alternatives of soil acidity management: lime, ash and sludge application. The applied indicators were energy return on investment, energy intensity and energy balance, which meant, respectively, the return over energy investment, the energy content of biomass and the energy obtained per area. For the basic scenario, lime, EROI was 58.5 MJ MJ-1, energy intensity was 124.7 MJ m-3, and the energy balance was 2120.7 GJ ha-1. The required energy was larger when ash (5.2%) and sludge (57.2%) were used. The main inputs were, in order, fuel, fertilizers, herbicide and lime. Harvesting was the main operation (56.7%), followed by subsoiling. Fuel in harvesting, fertilizers and lime summed 79.6% of the total energy. The sensitivity of the system showed that the material used to control soil acidity had more effect on the energy demand (up to +57.4%) than the suggested scenarios (-5.3% when the field efficiency was increased).; O contexto da racionalização dos sistemas de produção...

Unless energy can be produced and delivered more cheaply, it will stay beyond the reach of many of the poor. For energy delivered through networks, the costs that matter are not only the unit energy costs, but the costs of extending the network--into an urban slum, for example, or to a rural town. Extending a network can be very expensive--a major barrier to access for poor households and small or isolated communitieds. A central goal of the reform of electricity and gas networks, now occurring in an increasing number of developed and developing countries, is to provide incentives to reduce the costs of producing energy and getting it to consumers. New technologies in electricity are drastically reducing costs. But transmission costs are still a major hurdle to expanding networks in isolated or lightly populated areas. As a result it is the urban poor who stand the greatest chance of benefiting from network reform. For the rural poor, alternative solutions, including mini-grid and off-grid services, may be required.

Overwhelming evidence indicates that climate change, caused in large part by human activities, is already adversely impacting all people, with the very real prospect of worse to come. Nevertheless, a global treaty to curb carbon emissions remains elusive. In East Asia, all middle-income countries have set national targets for energy efficiency and renewable energy, and some even have targets for carbon reduction. This report focuses on recent experiences in applying public financing instruments and tries to draw the lessons to date: when and how to use the instruments, which instrument to select, and how to design and implement them. The wide range of financial instruments designed to support and catalyze clean energy investment over the last decade is truly remarkable. Such instruments include credit lines and risk guarantees designed to increase both the capacity and confidence of commercial banks for clean energy lending; dedicated funds and concessional financing mechanisms to kick-start new technologies; mezzanine and equity financing targeted at start-ups; small and medium enterprises and energy service companies; and various consumer financing instruments designed to lower the upfront costs of clean energy equipment. This report systematically reviews the successes and failures of innovative interventions and distills the lessons of applying them. This report is organized in following four parts: part one gives overview; part two focuses on financing energy efficiency; part three focuses on financing renewable energy; and part four focuses on clean energy financing case studies.

The increase in oil prices has created a growing economic pressure in Nicaragua. The electric power industry, especially, has generated controversy, because electricity prices have not kept pace with the costs of production. The situation at the beginning of 2006 was clearly unsustainable, and the entry of a new government provided an opportunity to refresh the vision of the sector, and address the problems. The objective of this note is to provide a balanced approach, taking into account both the short-term and long-term prospects of the sector, together with the lessons learned in similar situations. The questions facing the sector relate to its financial situation, the legal framework, the patterns of use of energy in Nicaragua, access and coverage of electric power, and its fiscal impact. Possibly the most important recommendation is to attenuate the disagreements with the government and seek areas of cooperation to improve the conditions of service. This should involve a quantification of the financial losses...

Pertamina Geothermal Energy (PGE) is leading Indonesia s effort to scale-up geothermal, attempting a globally unprecedented expansion of over 1,000 MW of capacity. The World Bank is helping kick-start PGE s investment program through the development of the Ulubelu (Units 3 and 4) and Lahendong (Tompaso) (Units 5 and 6) geothermal fields. Loans totaling US$ 300 million are being extended from the World Bank s facility for lending to middle-income countries through International Bank for Reconstruction and Development (IBRD) loans and from the global Clean Technology Fund (CTF) established to promote climate-friendly investments. To justify public support and evaluate the viability of this green finance investment, an integrated approach to decision making was utilized based on the combined assessments of financial-economic-stakeholder-risk impacts.

This thesis presents studies relating to effects of different macronutrients, predominantly fat and carbohydrate, on gastrointestinal motility, hormone release/suppression, appetite and energy intake in healthy subjects, and on symptom generation in patients with functional dyspepsia. The three broad areas that have been investigated in these studies are: (i) the effect of load, and duration, of small intestinal nutrient exposure on gastric motility, gastrointestinal hormone release/suppression, appetite and energy intake in healthy subjects, (ii) the dietary factors that may contribute to symptom generation in patients with functional dyspepsia, through analysis of diet diaries and acute nutrient challenges, and (iii) the effects of the herbal medication, Iberogast®, on gastric motility in healthy subjects. The ingestion of nutrients, triggers a number of gastrointestinal responses, including the modulation of antropyloroduodenal motility, gastrointestinal hormone release/suppression, and the suppression of appetite and energy intake, resulting in a slowing of gastric emptying to an average rate of 1 - 3 kcal/min, which is required for efficient nutrient digestion and absorption. Additionally, the rate at which glucose enters the small intestine influences postprandial glycaemia and incretin responses. These responses have been demonstrated in animals to be dependent on the length...

The European Union (EU) has set the objective to achieve a secure, sustainable and competitive energy. The development of a European energy policy is constantly emphasised in the declarations of EU political leaders. This thesis provides an assessment of the legal feasibility of an EU energy policy in the areas of industrial restructuring, institutional reform and security of supply. The first chapter looks into the Endesa saga, which offers a paradigmatic case concerning the tensions between energy champions and energy markets. Successive national and ‘foreign’ takeover bids for Endesa are examined at national and EU level by different authorities according to different legal regimes, which show the ambivalent contribution of the merger control to the development of an energy policy. The persistence of monopolistic structures despite energy liberalisation requires the reinforcement of the role of regulatory authorities, as analysed in chapter two. However, one cannot expect that national regulatory authorities and the newly created European Agency for the Cooperation of Energy Regulators enjoy the same powers and level of independence as their integration within Member States and the EU operates on the basis of different legal and institutional principles. Chapter three addresses security of energy supply...

MBA Professional Report; The amount of energy the United States (U.S.) consumes increases every year and this growth in energy consumption outpaces energy production. To fill this gap, the U.S. imports 35 percent of its energy. More importantly, the U.S. imports over 60 percent of its total oil consumption. Our country's energy production, especially our transportation sector, is highly dependent on foreign sources. Add to this, 70 percent of this energy is from non-renewable sources and this same 70 percent is petroleum-based, which produces greenhouse gas emissions. Renewable energy sources and alternative fuels have proven to be energy efficient, cost effective and environmentally friendly. Additionally, they reduce the country's dependence on foreign sources. The military is adopting many types of renewable energy sources and alternative fuels for use and the results are impressive. However, the majority of implementation is here in the United States. These same benefits experienced at home are available for the battlefield: improved energy efficiency, cost savings and less impact on the environment. This paper discusses the available green energy sources and their potential use for the battlefield. Additionally, it offers several ways to further the use and maximize the benefits of green energy on the battlefield.

MBA Professional Report; The Secretary of the Navy (SECNAV), the Honorable Ray Mabus, in an address to the Navy Energy Forum, announced as a new acquisition policy that the "lifetime energy cost of a building or a system, and the fully burdened cost of fuel in powering those, will be a mandatory evaluation factor used when awarding contracts." Secretary Mabus went on to say, "we will also use the overall energy efficiency and the energy footprint of a competing company as an additional factor in acquisition decisions" (Mabus, 2009). Secretary Mabus made this announcement and shared three other green and efficiency goals for the Department of the Navy. His address now puts the onus on the Navy acquisition community to implement the broad policy goals that he outlined. A challenge to the community will be how to implement these goals with a uniform, objective, and definable standard that is able to withstand the scrutiny of congress, which requires full and open competition, the business models of the defense industry, and the legal challenges that are sure to follow as a result of competition. This project analyzes the challenges of implementing Secretary Mabus's announcement. Our analysis further defines the problem, offers recommendations for proceeding...

Security of energy supply is a top priority of policymakers around the globe, especially in countries of the economically emerging world. This paper's aim is to investigate the link between the mode of governance in four developing countries and the way policies to secure energy supply are established. The paper looks at the four "BRIC" countries, Brazil, Russia, India, and China. These countries are experiencing rapid economic growth and poverty alleviation but differ in their modes of governance. The four BRIC countries provide a window into the particular relationship between governance and energy security policy in developing countries. From a theoretical stance, a public choice model is applied to energy policies to develop hypotheses relating the similarities and differences of incentive schemes between democratic and authoritarian governments to predict policy outcomes. We hypothesize that authoritarian regimes seek control and the capability to reward and repress social groups by providing public goods, such as energy supply. In the first empirical step, the current energy economic performance is examined by focussing on domestically available resources, de-concentration and decentralization of the supply side and energy development indices. Doing so...

We take a fresh look at the major nonrenewable and renewable energy sources and examine their long-term viability, scalability, and the sustainability of the resources that they use. We achieve this by asking what would happen if each energy source was a single supply of power for the world, as a gedanken experiment. From this perspective, a solar hydrogen economy emerges as a dominant solution to the world's energy needs. If we globally tap sunlight over only 1% of the incident area at only an energy conversion efficiency of 1%, it is simple to show that this meets our current world energy consumption. As 9% of the planet surface area is taken up by desert and efficiencies well over 1% are possible, in practice, this opens up many exciting future opportunities. Specifically, we find solar thermal collection via parabolic reflectors - where focussed sunlight heats steam to about 600?C to drive a turbine - is the best available technology for generating electricity. For static power storage, to provide electricity at night, there are a number of viable options that are discussed. For mobile power storage, such as for fueling vehicles, we argue the case for both liquid and gaseous hydrogen for use in internal combustion engines. We outline a number of reasons why semiconductor solar cells and hydrogen fuel cells do not appear to scale up for a global solution. We adopt an approach that envisions exploiting massive economy of scale by establishing large arrays of solar collectors in hot desert regions of the world. For nonrenewable sources we argue that we cannot wait for them to be exhausted - we need to start conserving them imminently. What is often forgotten in the energy debate is that oil...

The measurement of the ultra high energy cosmic ray (UHECR) spectrum is strongly affected by uncertainties on the reconstructed energy. The determination of the presence or absence of the GZK cutoff and its position in the energy spectrum depends not only on high statistics but also on the shape of the energy error distribution. Here we determine the energy error distribution for fluorescence telescopes, based on a Monte Carlo simulation. The HiRes and Auger fluorescence telescopes are simulated in detail. We analyze the UHECR spectrum convolved with this energy error distribution. We compare this spectrum with one convolved with a lognormal error distribution as well as with a Gaussian error distribution. We show that the energy error distribution for fluorescence detectors can not be represented by these known distributions. We conclude that the convolved energy spectrum will be smeared but not enough to affect the GZK cutoff detection. This conclusion stands for both HiRes and Auger fluorescence telescopes. This result differs from the effect of the energy error distribution obtained with ground detectors and reinforces the importance of the fluorescence energy measurement. We also investigate the effect of possible fluorescence yield measurement errors in the energy spectrum.; Comment: 24 pages...

In models where dark matter and dark energy interact non-minimally, the total amount of matter in a fixed comoving volume may vary from the time of recombination to the present time due to energy transfer between the two components. This implies that, in interacting dark energy models, the fractional matter density estimated using the cosmic microwave background assuming no interaction between dark matter and dark energy will in general be shifted with respect to its true value. This may result in an incorrect determination of the equation of state of dark energy if the interaction between dark matter and dark energy is not properly accounted for, even if the evolution of the Hubble parameter as a function of redshift is known with arbitrary precision. In this paper we find an exact expression, as well as a simple analytical approximation, for the evolution of the effective equation of state of dark energy, assuming that the energy transfer rate between dark matter and dark energy is described by a simple two-parameter model. We also provide analytical examples where non-phantom interacting dark energy models mimic the background evolution and primary cosmic microwave background anisotropies of phantom dark energy models.; Comment: 5 pages...

We constrain plausible dark energy models, parametrized by multiple candidate equation of state, using the recently published Cosmic Microwave Background (CMB) temperature anisotropy data from Planck together with the WMAP-9 low-$\ell$ polarization data and data from low redshift surveys. To circumvent the limitations of any particular equation of state towards describing all existing dark energy models, we work with three different equation of state covering a broader class of dark energy models and, hence, provide more robust and generic constraints on the dark energy properties. We show that a clear tension exists between dark energy constraints from CMB and non-CMB observations when one allows for dark energy models having both phantom and non-phantom behavior; while CMB is more favorable to phantom models, the low-z data prefers model with behavior close to a Cosmological Constant. Further, we reconstruct the equation of state of dark energy as a function of redshift using the results from combined CMB and non-CMB data and find that Cosmological Constant lies outside the 1$\sigma$ band for multiple dark energy models allowing phantom behavior. A considerable fine tuning is needed to keep models with strict non-phantom history inside 2$\sigma$ allowed range. This result might motivate one to construct phantom models of dark energy...

The residential sector accounts for a substantial percentage of total energy use in the United States. Newer homes built under the ENERGY STAR label have increased awareness for home energy efficiency, but there is no standard metric for evaluating the energy use of older housing stock. To fill this gap the U.S. Department of Energy (DOE) created the Home Energy Score (HEScore) that scores existing homes on a 10-point scale based on energy performance. The score, along with a detailed home report, provides homeowners with a list of recommended improvements that – if implemented – will increase a home’s efficiency and HEScore. Through this program the DOE hopes to improve the overall efficiency of U.S. homes. This master’s project investigates behavioral and economic factors that influence homeowners’ willingness to pay (WTP) for energy-efficient home improvements, specifically as they relate to the DOE’s HEScore. An experiment using a contingent valuation study was designed to measure how situational factors and the decision environment influence a homeowner’s WTP for specific energy-efficient improvements. The experiment was delivered via an online survey to more than 1,600 current homeowners, home buyers and home sellers throughout the U.S. A response rate of 56 percent was achieved. Results of the study indicate that no single agent influences a homeowner’s choice in their WTP for energy-efficient improvements; rather it is a complex mix of socioeconomic...

With the rapid growth in the use of portable electronic devices, more emphasis has recently been placed on low-energy circuit design. Digital subthreshold complementary metal-oxide-semiconductor (CMOS) circuit design is one area of study that offers significant energy reduction by operating at a supply voltage substantially lower than the threshold voltage of the transistor. However, these energy savings come at a critical cost to performance, restricting its use to severely energy-constrained applications such as microsensor nodes. In an effort to mitigate this performance degradation in low-energy designs, nearthreshold circuit design has been proposed and implemented in digital circuits such as Intel's energy-efficient hardware accelerator. The application spectrum of nearthreshold and subthreshold design could be broadened by integrating these cells into high-performance designs. This research focuses on the integration of characterized nearthreshold and subthreshold standard cells into high-performance functional modules. Within these functional modules, energy minimization is achieved while satisfying performance constraints by replacing non-critical path logic with nearthreshold and subthreshold logic cells. Specifically...

The aim of this research was to examine the energy use pattern, energy use efficiency and energy productivity for vegetable production under Fadama or the seasonally flooded or floodable plains along major savanna rivers in north central Nigeria. To achieve these objectives, the data for the production of four major vegetables produced under Fadama (Onion, Tomato, Sweet and Hot Pepper) were collected from 192 Fadama farmers. The results show that Tomato production was the most energy intensive among the four vegetables investigated. For all the vegetables, the usage of non-renewable energy inputs such as petrol and urea fertilizer was quite substantial as such, the efficiency of energy use and energy productivity were very low. The energy use efficiency were, 0.20, 0.10, 0.10 and 0.06, while the energy productivity were 0.25, 0.12, 0.13 and 0.07 for Onion, Tomato, Sweet and Hot Pepper respectively. However, to enhance the energy use efficiency and energy productivity of the system, the usage of renewable energy inputs especially organic manure should be promoted. In addition, energy efficient water pumps should be introduced into the Fadama communities.

Escalating energy and electricity costs have become one of the largest drivers of expenditure in mining operations. Over the last eight years, energy costs have tripled when expressed as a percentage of total expenses in South African mines. In an effort to manage and reduce electricity costs, energy management strategies can be developed, inefficient operating units replaced, and the operation of energy-consuming components of ventilation systems optimized. Power consumption on mines is controlled mainly by three strategies, namely load clipping, by which energy use is reduced for certain parts of the day; load shifting, by which energy use is shifted to other parts of the day; and energy efficiency, by which energy use is reduced permanently. In this paper several projects that were implemented using the first two strategies of load clipping and load shifting are investigated. The actual and potential savings that can be achieved by implementing such energy-saving interventions are presented. To reduce the operating costs of ventilating and cooling underground mines permanently, system optimization studies must be completed. Methods that can be used to reduce energy usage by optimizing cooling and ventilation systems are described...

The study was conducted to determine the effects of feeding diets containing two levels of metabolisable energy (normal or low) and three sources of fat (palm-, sunflower- or fish-oil) with or without L-carnitine (0 or 500 mg/kg diet) on the performance and egg quality parameters of Brown egg-type laying hens. The hens receiving the low energy diet had significantly higher body weights and feed intakes (FI) than the birds on the normal energy diet, but their feed conversion ratio (FCR) was poorer. L-carnitine in the diet containing sunflower oil (SO) increased FI significantly, resulting in a poorer FCR. However, the FI and FCR were higher when the fish oil (FO) was added to diets without L-carnitine compared to the other diets. The palm oil (PO) supplemented diet without L-carnitine significantly decreased the specific gravity of the eggs. L-carnitine inclusion into the diet containing PO significantly increased the Haugh unit and albumen index of the eggs, while the inclusion of FO in the low energy diet increased the Haugh unit and albumen index significantly. However, when PO was included these parameters decreased significantly. The addition of L-carnitine to the normal energy diet reduced the pH of the egg yolk, while it increased egg yolk pH when added to the low energy diet. The inclusion of FO in the low energy diet resulted in a significant increase in yolk pH. Albumen pH was significantly decreased by dietary L-carnitine supplementation...

For today's world, energy is a huge requirement for economic, industrial and social life. The necessity of energy is increasing quite rapidly to keep pace with the technological and economical advancements and this brings about many energy problems like, dependence on energy importation, environmental pollution, global warming, increasing cost of energy expenses and inefficiency in energy use etc. Countries are working very hard to solve these problems. To supply the energy needs and protect our planet's future safety, it is very important to generate clean energies. In this context, governments give huge amounts of incentives for renewable energy generations and support related investments in many countries. In this study, the importance of renewable energy usage, recent incentives, renewable energy policies in Turkey and some developed countries are investigated and compared. It is also aimed to examine the real situation of renewables in Turkey by giving the latest numbers and make a contribution of future developments for these clean energies in Turkey. In this regard, some barriers and recommendations are also submitted.
