Enquadramento legal e estudo económico de parques eólicos

Portugal, no intuito de alcançar metas ambientais e económicas a que se propôs, e de reduzir a dependência das importações de energia, tem aumentado o investimento em eletricidade produzida a partir de energias renováveis (FER-E). Apesar do consenso em torno da sua utilização, as energias renováveis deparam-se com barreiras de várias ordens que dificultam a sua difusão no mercado. A atuação do Estado neste enquadramento passa por criar modelos de promoção da FER-E. A maioria dos países da União Europeia, incluindo Portugal, aplica as tarifas feed-in (FIT) como instrumento central de suporte à FER-E, inserido num modelo de apoio que contempla outros parâmetros de construção considerados críticos para o seu sucesso. No seguimento do estágio realizado na empresa Senvion Portugal a presente tese explora os programas e modelos de apoio às FER-E em Portugal, nomeadamente as que se referem à energia eólica. Bem como os trabalhos realizados com as equipas de O&M e a realização de um estudo de viabilidade económica da substituição de aerogeradores no parque eólico de Picos Verdes II.

Factors that influence entrepreneurship activity by gender in the European Union

This research work aims to discuss the gender issue concerning entrepreneurship in European Union countries in a period of nine years, from 2007 to 2015, identifying the factors which drive individuals to be entrepreneurs. The study mainly concentrates on identifying and quantifying the personal, social, political and economic features which are motivating individuals, especially women, to be entrepreneurs, as well as the main difficulties they feel during the process of business creation. In order to explore the entrepreneurial activity across a set of developed countries the econometric methodology of panel data (in particular the fixed effects and random effects models) is applied to a data set of entrepreneurial statistical indicators calculated and made available by the Global Entrepreneurship Monitor. The results show that the knowledge of other start-up entrepreneurs, a desired career choice, the governmental support and the existence of public policies that promote entrepreneurship (specially within the framework of small and medium sized firms) and the transfer of R&D are factors influencing negatively on the rate of female entrepreneurship. None of the observed variables are barriers for male entrepreneurs. The perceived capabilities and opportunities, the entrepreneurial intention, the policies to lower taxes and bureaucracy and the social and cultural norms are identified drives for women for engaging in a process of running their own ventures. These findings offer a set of valid knowledge to understand which measures could be implemented or should be changed and improved at a political and managerial level for stimulating entrepreneurship, especially for women.
