This study examines two of the reasons that prevent people from taking part in green electricity programs: trust concerns that these programs may raise, and lack of benefits that come with visibility of participants’ involvement. While the current literature takes notice of their influence, in this study it was decided to investigate both factors in more detail. In particular, with the help of a survey, the study focused on the reactions of electricity consumers to the proposition of participation in green electricity programs in a controlled setting, in which levels of trust concerns raised and benefits of visibility provided by the programs could be varied. The study was conducted in Oakville, an affluent southern Ontario (Canada) suburb. The results are based on 160 received responses to 500 questionnaires that were sent out by mail. While the results of this study point towards the conclusion that both factors have an influence on participation in green electricity programs, their relative strength cannot be estimated by these results. One can, however, claim that the combined influence of trust concerns and benefits of visibility is quite strong. This research shows that at a 95% confidence level, willingness to participate in a program that proposes paying premium for electricity from solar panels installed on a participant’s roof (low trust concerns, high benefits of visibility) is 30% + 19.3% higher than willingness to participate in a program that proposes paying premium for electricity from undisclosed solar farms (high trust concerns, low benefits of visibility). Additional data about trust concerns, appreciation of benefits of visibility, and concerns about installation of solar panels on one’s own roof, provided by the survey, are also presented in the text. In conclusion, it is recommended that future research should more clearly separate the strength of influence of trust concerns from the influence of benefits of visibility on green electricity program participation. It is also important to study which features of these programs make them more trustworthy and visible. An important implication of this study for policy makers and green electricity proponents is to concentrate on allaying trust concerns, and enhancing benefits of visibility when designing policies or drafting plans for green electricity programs. The creation of an independent green electricity program certification system and a greater accent on the local presence of such programs is suggested.

This thesis aims to analyze the Turkish policy of being an energy hub. Within this context Turkey, as it is geographically very close to the two thirds of the world&#039 / s proven oil and natural gas reserves, has a very big advantage to manage its location and the purpose of this study is to discuss the measures taken to utilize this advantage. Therefore relative weakness of Turkey in comparison to the other actors like Russia, the USA or the EU and the strengths of the Turkish policy like the geopolitical advantage, the ethnic link between Turkey and the newly independent states of the Caspian and the already existing infrastructure for the transportation of oil and natural gas like Kirkuk-Yumurtalik Pipeline, Baku Tblisi Ceyhan Oil Pipeline, Ceyhan Terminal, and Baku Tblisi Erzurum Natural Gas Pipeline are discussed. With this respect, this study argues that, as a result of the existing and planned projects, Ceyhan&#039 / s claim to become a hub is a realistic objective and in addition to BTC and Kirkuk-Yumurtalik Pipeline, the realization of Samsun-Ceyhan Pipeline will increase Ceyhan&#039 / s potential as an energy hub.

There are a series of state and federal incentives in California to encourage the installation of distributed generation (DG) renewable energy, largely photovoltaic (PV). This thesis explores the policies behind the incentives, namely the Federal Investment Tax Credit, California Solar Initiative, and Net Energy Metering requirements. Discussion is informed by environmental policy tools, as well as business models that have acted to increase accessibility to these investment-intensive projects. Underlying this analysis is the theme of a shifting energy paradigm, with distributed generation spreading political, economic, and electric power.

This thesis consists of four self-contained papers related to energydemand and household cooking energy.Paper [I] examine the impact of price, income and non-economicfactors on gasoline demand using a structural time series model. Theresults indicated that non-economic factors did have an impact ongasoline demand and also one of the largest contributors to changes ingasoline demand in both countries, especially after the 1990s. Theresults from the time varying parameter model (TVP) indicated thatboth price and income elasticities were varying over time, but thevariations were insignificant for both Sweden and the UK. Theestimated gasoline trend also showed a similar pattern for the twocountries, increasing continuously up to 1990 and taking a downturnthereafter.Paper [II] studies whether the commonly used linear parametricmodel for estimating aggregate energy demand is the correctfunctional specification for the data generating process. Parametricand nonparametric econometric approaches to analyzing aggregateenergy demand data for 17 OECD countries are used. The resultsfrom the nonparametric correct model specification test for theparametric model rejects the linear, log-linear and translogspecifications. The nonparametric results indicate that the effect of theincome variable is nonlinear, while that of the price variable is linearbut not constant. The nonparametric estimates for the price variable isrelatively low, approximately −0.2.Paper [III] relaxed the weak separability assumption betweengasoline demand and labor supply by examining the effect of laborsupply, measured by male and female working hours on gasolinedemand. I used a flexible semiparametric model that allowed fordifferences in response to income, age and labor supply, respectively.Using Swedish household survey data, the results indicated that therelationship between gasoline demand and income, age and laborsupply were non-linear. The formal separability test rejects the null ofseparability between gasoline demand and labor supply. Furthermore,there was evidence indicating small bias in the estimates when oneignored labor supply in the model.Paper [IV] investigated the key factors influencing the choice ofcooking fuels in Ghana. Results from the study indicated thateducation, income, urban location and access to infrastructure werethe key factors influencing household’s choice of the main cookingfuels (fuelwood, charcoal and liquefied petroleum gas). The study alsofound that, in addition to household demographics and urbanization,the supply (availability) of the fuels influenced household choice forthe various fuels. Increase in household income was likely to increasethe probability of choosing modern fuel (liquefied petroleum gas andelectricity) relative to solid (crop residue and fuelwood) and transitionfuel (kerosene and charcoal).

Over the past ten years, the State of California has realized environmental, economic, and social benefits through the increased deployment of solar photovoltaic technologies. However, utility-scale and residential-scale solar projects also pose a variety of problems, which have created barriers to their broader adoption. Community solar projects offer a model for solar development that can reduce the problems associated with utility-scale and residential-scale projects, while simultaneously preserving the benefits of each. This thesis examines the problems associated with current solar projects and proposes policy to support the community solar project model in California.

A paradigm shift in distribution system design and planning is being led by the deregulation of the power industry and the increasing adoption of distributed generation (DG). Technology advances have made DG investments feasible by both local distribution companies (LDCs) and small power producers (SPPs). LDCs are interested in finding optimal long term plans that best serve their customers at the lowest cost. SPPs, as private entities, are concerned about maximizing their rates of return. Also keenly interested in distribution design and planning is the government, which, through an electricity regulator, strives to meet DG penetration and emissions reduction goals through policy implementations. This thesis first examines the distribution system planning problem from the LDC's perspective. An innovative hierarchical dynamic optimization model is proposed for the planning of distribution systems and the energy scheduling of units that is also capable of reconciling uncoordinated SPP investments in DG. The first stage of the two-stage framework consists of a siting-cum-period planning model that sets element sizing and commissioning dates. The second stage consists of a capacity-cum-production planning model that finalizes element capacities and energy import/export and production schedules. The proposed framework is demonstrated on a 32-bus radial distribution system. Four case studies encompassing different policy sets are also conducted, demonstrating that this model's usefulness also extends to predicting the impact of different energy policies on distribution system operation and economics. The analysis of different policy sets is further expanded upon through the proposal of a new mathematical model that approaches the distribution design problem from the regulator's perspective. Various case studies examining policies that may be used by the regulator to meet DG penetration and emissions goals, through DG investment, are constructed. A combination of feed-in-tariffs, CO$_2$ tax, and cap-and-trade mechanisms are among the policies studied. The results, in the context of Ontario, Canada and its Standard Offer Program, are discussed, with respect to achieving objectives in DG investment, participation by SPPs, consumer costs, and uncertainty in carbon market prices. In jurisdictions such as Ontario, the LDC cannot invest in its own DG capacity but must accommodate those of SPPs. With the successful implementation of DG investment incentives by the regulator, there is a potential for significant investments in DG by SPPs, which may exceed that of the LDCs ability to absorb. This thesis proposes a novel method that can be used by the regulator or LDC to fairly assess, coordinate, and approve multiple competing investments proposals while maintaining operational feasibility of the distribution system. This method uses a feedback between the LDC and SPPs to achieve maximum investor participation while adhering to the technical operational limits of the distribution system. The proposed scheme is successfully demonstrated on a 32-bus radial distribution system, where it is shown to increase SPP-DG investments and production, improve the system's voltage profile, and reduce losses.

There were three big oil crises in twenty century, and all made international political shakes. The global warming triggered the climate change, the rising of sea horizon and other environmental problems. The advanced countries begin to think about decreasing the dependency of fossil fuels as economic grows. Both the Kyoto Protocol in 1997 and the United Nations Copenhagen Climate Change Conference in 2009 were the evidences that most of the countries in the world are all concerned about climate change and economical environments. Furthermore, the Kyoto Protocol and the United Nations Climate Change Conferences affected the global economic policies, and also generated new ideas of green economy. Because of the impacts from the environmental and economic view, many countries made new green energy policies to develop renewable energy, promote green industry, wake up environment protection ideas, and broadcast the education of save energy saving and carbon reduction. This thesis uses the historical method, content analysis method and comparative method and the public policy theory as the theory basement. Then the thesis introduces the summary of global green energy industry. Taiwan and Singapore are called as Four Asian Little Dragons, but both lack of nature resources and depend on energy importation. The thesis discusses the policies on green industry of the Taiwan and Singapore, and also discusses the outputs of the policies. The final part is the policy comparisons between the two governments.

The Caspian region hydrocarbons are important for international energy security. Producer, consumer and transit countries, albeit for different reasons, try to get a share of these new resources. The opening up of the Region has presented Turkey with a new set of opportunities. In this thesis the positions of all the countries involved are examined. Special attention is given to Turkish policies towards the region. In conclusion the geopolitical environment emerged around the hydrocarbon resources and pipelines is evaluated. It will be seen that this environment puts Turkey in a very favorable position and Turkey is now a player in the international energy game despie the fact that it has almost no hydrocarbon resources.
