Large-scale solar deployment is sensitive to several factors including future solar technology price and performance, electricity demand, and the challenges and benefits of integrating solar generation resources. The SunShot Initiative was launched by the U.S. Department of Energy (DOE) in 2011 aimed at reducing the cost of solar electricity by about 75% from 2010 to 2020, whereby solar energy could...
In this paper the distribution of world's electricity sources is presented graphically. The contribution of renewable energy sources is focused here. The CO2 emission rate has been discussed from various aspects. A prediction model is presented for world electricity generation capacity, electricity consumption, CO2 emission rate and renewable energy harnessing. At last a brief energy prediction model...
Distributed generation can play an important role in the complex portfolio of environmental and climate friendly technologies. Both renewable sources-fueled and fossil-fueled power plants show potentials to increase the overall efficiency of energy systems therefore to mitigate their impact: policy makers have learnt of their importance and now, at local level, the situation seems the opposite of...
Establishing the local feasibility of using distributed generation sources (a micro-grid) is the focus of this project, where an 81-house neighborhood in Chandler, Arizona was chosen to serve as the model. An in-depth analysis of the current energy and water use of the neighborhood and its associated cost to the consumer, along with an evaluation of the capacity of the existing infrastructure, was...
The need for flexible electricity systems, changing regulations and the importance of renewable energy use may lead in time to the requirement of a decentralised electricity network. This paper presents an outline for developing a model of the decentralised energy network based on `energy hubs'. Energy hubs are units whereby multiple energy carriers are converted to energy services such as electricity...
Sustainability is becoming an issue of public concern, particularly for large scale development projects. In this work, a multi-criteria approach, called the sustainability assessment method (SAM), is used to asses and rank the sustainability of various types of power plants firing on different types of fuel. It traces the impacts of using coal, oil, and natural gas for power generation over its full...
The purpose of this paper is to evaluate the efficiency of a network of natural gas power plants using the Data Envelopment Analysis approach. The network is modeled as a linear system with multiple inputs and outputs. As inputs one could consider, for instance, the age of a plant, the total number of hours that a plant is in operation during each year, etc. As outputs the model considers the electrical...
The aim of this work is to present a daily simulation model for future technical and economical analysis of natural gas microturbine for the ceramic industry. From the energy generation side, the model is based on the microturbine electrical and thermal efficiency. From the load side, the model is based on continuous load curves. The model was simulated in STELLA, the main advantage of this method...
This paper describes a novel approach for strategic investment planning based on real options analysis and its application to a single investor within the German electricity sector. It takes into account the long-term uncertainty in fossil fuel prices of natural gas and coal as well as the power plant's short-term flexibility to react on fluctuating electricity prices by means of its actual operation...
This paper summarizes a modeling framework that characterizes the key underlying technologies and processes that contribute to the supply chain energy use and greenhouse gas (GHG) emissions of a variety of goods and services purchased by U.S. consumers. The framework couples an input-output supply chain modeling approach with ldquobottom-uprdquo fuel end use models for individual IO sectors. This...
In the last few years we have observed deregulation in electricity markets and an increasing interest of price dynamics has been developed especially to consider all stylized facts shown by spot prices. Only few papers, to the authors' knowledge, have considered the Italian Electricity Spot market since it has been deregulated recently. Therefore this contribution is an investigation with emphasis...
A major problem that the United States is facing in the 21st century is meeting energy needs. With an ever-increasing population, a question arises: can we generate and deliver enough energy in order to meet the ever-increasing demand? Each day more and more people are using automobiles to go from place to place, but there is a single point of failure in automotive design: petroleum based fuels. Travel...
This paper presents an outline for a development stage model of the UK energy infrastructure. The model will use transition pathways as inputs to simulate the UK energy infrastructure toward 2050. Transition pathways are socio technical narratives that are used here to describe possible evolutions of the UK energy industry as it moves towards 2050 and a lower carbon economy. It is the aim of the authors...
The Gulf Cooperation Council (GCC) is nearing the completion of a high voltage transmission system designed to integrate the power systems of Saudi Arabia, Kuwait, Bahrain, Qatar, the United Arab Emirates and Oman. The objective of this paper is to review the underlying economics of electric supply within the GCC before interconnection, to evaluate the plans for further developments in generation...
This paper sets up a dynamic model of energy consumption structure in China and selects two different groups of data to simulate and forecast the trend of the energy consumption structure. The forecast result is that the consumption rate of coal will decrease, while the rates of electricity, natural gas and petroleum will increase. Because the two groups of data are from different periods, there is...
The most significant energy consuming infrastructures and the greatest contributors to greenhouse gases for any nation today are electric and freight/passenger transportation systems. Technological alternatives for producing, transporting, and converting energy for electric and transportation systems are numerous. Addressing costs, sustainability, and resiliency of electric and transportation needs...
The integration of natural gas and electricity sectors has increased as a consequence of the growing installation of natural gas fired power plants (NGFPP). This paper presents a comprehensive literature survey of previous researches on integrated natural gas and electricity operation planning. The relevant characteristic of natural gas and electricity systems are compared. A brief description of...
This paper describes about the 20% Electricity from Wind scenario and it was examined not just for its feasibility but also for its benefits, costs and impacts on the energy sector, the economy, and environmental and climate change goals. This paper summarizes the principal results of these analyses, conducted primarily at the National Renewable Energy Laboratory (NREL) and the Lawrence Berkeley Laboratory...
With increasing investment in natural gas powered generation technologies, limitations in gas delivery capabilities are becoming increasingly relevant to operational planning for electric power systems. Thus it is essential to model and analyze the impact of the interdependency between natural gas and electricity infrastructures. This paper tries to convey the idea that, through an integrated modeling...
