This thesis focuses on the renewable energy policies for the case study countries (European Union, United States, United Kingdom, Turkey, and Nigeria) with using quantitative and qualitative analysis. The thesis adopts a three -pronged approach to address three main issues: The first paper investigates a 1990-2008 panel dataset to conduct an econometric analysis of policy instruments, such as; feed-in tariffs, quotas, tenders, and tax incentives, in promoting renewable energy deployment in 27 EU countries and 50 US states. The results suggest that renewable energy policy instruments play a significant role in encouraging renewable energy sources. Using data from 1990 to 2012 with the vector auto regression (VAR) approach for three case study countries, namely United Kingdom, Turkey, and Nigeria, the second paper focuses on how renewable energy consumption as part of total electricity consumption is affected by economic growth and electricity prices. The findings from the VAR model illustrate that the relationship between case study countries’ economic growth and renewable energy consumption is positive and economic growth in case study countries respond positively and significantly. The third paper focuses on the relationship between renewable energy policies and investment in renewables in the countries of United Kingdom and Turkey. The third paper builds upon current knowledge of renewable energy investment and develops a new conceptual framework to guide analyses of policies to support renewables. Past and current trends in the field of renewable energy investment are investigated by reviewing the literature on renewable energy investment linkage with policies, which identifies patterns and similarities in RE investment. This also includes the interview analysis with investors focusing on policies for renewable energy investment. The results from the interview and conceptual analysis show that renewable policies play a crucial role in determining investment in renewable energy sources. The findings from this thesis demonstrate that renewable energy policies increase with a growth of the renewable energy investment in the sector. Finally, the outcomes of this thesis also contribute to the energy economics literature, especially for academic and subsequent research purposes.

A produção e o consumo energético de energia têm grande impacto na sociedade e na natureza, e o uso dos combustíveis fósseis é claramente insustentável com consequências potencialmente catastróficas. Desta forma, a necessidade de transição para uma matriz energética mais limpa é evidente, podendo ser observada através do redirecionamento da política energética de algumas das nações líderes do mundo. Dentre as tecnologias energéticas limpas, a tecnologia solar tem se destacado no cenário mundial, e por hipótese a energia solar deverá ser a principal fonte para geração de eletricidade no futuro. Esta dissertação pretende contribuir com a investigação acerca do desenvolvimento e perspectivas da energia solar no mundo, trazendo alguma luz à controvérsia sobre a possibilidade de superação do paradigma energético baseado na combustão de fósseis a tempo de se evitar um possível desastre ambiental. O presente trabalho divide-se em três partes. A primeira parte trata da necessidade da transição da matriz energética baseada em uso de combustíveis fósseis para uma baseada em energia limpa, essencial em decorrência das já comprovadas limitações ambientais, que se agravará futuramente diante da expectativa de largo aumento na demanda de energia para acompanhar o crescimento econômico futuro. A segunda parte faz uma breve discussão acerca de algumas questões relativas à construção de um novo paradigma energético e da inovação em tecnologias de energia de baixo carbono, além de salientar especificidades da tecnologia solar. Por fim, na terceira parte traça-se um panorama do cenário atual mundial com relação ao setor de energia solar a partir dos principais países que investem na tecnologia: Estados Unidos, Alemanha, Japão e China. Neste capítulo será analisado o progresso do setor solar em cada país, apontando as políticas de incentivo, desenvolvimento da indústria solar, evolução do mercado e perspectivas futuras da energia solar / Abstract: The world reserves of oil, coal and natural gas can accommodate further growth in energy use over the next few decades, but aggravates the great challenges posed by climate change. The production and consumption of energy have been creating great impact in our society and nature, and the consumption of fossil fuels is clearly unsustainable with potentially catastrophic consequences. Thus, the importance of renewable forms of energy is growing robustly, which can be observed by the energy policies of some of the leading nations in the world. Among the renewable forms of energy, solar power generation is becoming mainstream and by hypothesis is likely to become the world¿s most important source for electricity generation in the future. This thesis aims to contribute on the research concerning the development and prospects of solar energy in the world, bringing some light to the controversy about the possibility of overcoming the energy paradigm based on the combustion of fossil in time to prevent a possible environmental disaster. This paper is divided into three parts. The first one highlight the need for a transition from a fossil fuel-based society to one based on renewable energy, enabling a more sustainable growth. The second part is a brief discussion regarding the construction of a new energy paradigm and the innovations in the in low-carbon energy technologies, highlighting specific characteristics of the solar technology. Finally, the third part makes an overview of the current scenario, especially the one regarding the solar industry in the most advanced countries in the development of solar energy (United States, Germany, Japan and China). In this chapter an analysis is made about the progress of the solar energy in each country, pointing out government subsidies, industry and market development and future prospects of solar energy / Mestrado / Desenvolvimento Economico, Espaço e Meio Ambiente / Mestra em Desenvolvimento Econômico
