Resumo
[Abstract] The proposed study analyzes the efciency of the European energy mix of electricity generation technologies from two perspectives: environmental and economic. The context
is that of European energy dependence and a technology mix conditioned by the import
of fossil fuels. The impact is centered, among other elements, on the leakage of national
income and the emission of polluting gases. The aim is to determine the participation that
each type of power plant in each country should present in order to minimize the total
environmental impact. In order to solve this problem, a double optimization is proposed
through the use of two methodologies: one based on a multi-criteria decision-making
method (MCDM) model with which to evaluate the environmental performance of each
power plant, and a second optimization based on a quadratic model of portfolios modern
portfolio theory (MPT), with which to evaluate the efciency of the portfolio of technologies from the cost/risk binomial. The results confrm that an environmentally efcient
portfolio leads to higher levels of economic risk-taking, with a slight increase in the level
of assumed cost. Nevertheless, from the results obtained, it is possible to say that hydro
(with a share between 11 and 13%) and wind (37–44% mix participation) technologies
resulted to be preferred options both environmentally and in terms of minimum risk efciency. Nuclear power generation stands out as one of the main baseload technologies with
shares between 25 and 35% in environmental and cost/risk efciency. As main fndings,
Hydro, supercritical lignite, solar PV and wind are identifed as preferential technologies to
be present in both minimum risk and minimum cost efcient portfolios. In case European
Union pursues for minimizing the cost of electricity production, the shares of supercritical
lignite, nuclear, solar PV and wind energy go up to the maximum allowed limits. The novelty lies in the application of both methodologies with which to complement the analysis
and design efcient portfolios of energy technologies from environmental and economic
points of view. One possible future approach would be to assess (with the MPT model)
new environmentally optimal portfolios obtained through the application of other MCDM
techniques.
