Grid parity of solar energy: imminent fact or future's fiction

Spiros Papaefthimiou, Manolis Souliotis, and Kostas Andriosopoulos

Year: 2016
Volume: Volume 37
Number: Bollino-Madlener Special Issue

Abstract:
One of the major questions related to renewable energy systems is whether we are approaching solar grid parity or not. Solar based power generation will play an important role in future sustainable energy mixes due to its high reliability, yield predictability and capacity for electricity production during peak demand when the electricity price is usually high. But nowadays the economic viability of these technologies depends on the subsidies usually granted, mainly by public authorities, and in a minor way by electricity producers. The article evaluates the potential of solar energy based technologies for viable electricity generation, focusing on Photovoltaics (PV) and Concentrated Solar Power (CSP) systems. The evaluation was not only focused on EU but also covered global markets, assessing the necessary barriers and thresholds preventing or boosting these technologies to reach grid parity. The observed rapid growth in deployment of the studied technologies (especially PV) in recent years is largely policy-driven and whether this trend will be sustainable depends on whether governments will continue to expand financial incentives and policy mandates, as well as address regulatory and market barriers. Keywords: Solar energy, Grid parity, Photovoltaics, Concentrated Solar Power systems.



A Multicriteria Assessment Approach to the Energy Trilemma

Athanasios Pliousis, Kostas Andriosopoulos, Michalis Doumpos, and Emilios Galariotis

Year: 2019
Volume: Volume 40
Number: The New Era of Energy Transition
DOI: 10.5547/01956574.40.SI1.apli
View Abstract

Abstract:
The development of sustainable energy systems is pivotal in addressing climate change, but is also a complex and multifaceted task that should take into consideration a wide range of technological and socio-economic issues. The energy trilemma concept acknowledges this complexity and emphasizes the need to achieve a balance among three main dimensions: energy security, energy equity, and environmental sustainability. This study provides a systematic treatment of the energy trilemma at the country level. A novel multicriteria assessment framework is employed to evaluate the related performance of countries. Such an evaluation provides useful results for policy making, as it enables the examination of the status of each country and the challenges that it faces in achieving energy sustainability. The obtained empirical results are analyzed over time as well as considering the characteristics of the countries.



The New Era of Energy Transition: Challenges, Investment Opportunities and Technological Innovations

Kostas Andriosopoulos and Spiros Papaefthimiou

Year: 2019
Volume: Volume 40
Number: The New Era of Energy Transition
DOI: 10.5547/01956574.40.SI1.kand
View Abstract

Abstract:
It is an undeniable fact that we are witnessing a new evolving era in the global energy scenery. This non-stable situation poses serious questions, challenges and opportunities for countries, industries, professionals and academics. The objective of this special issue is to focus on the energy sector which should constantly adapt to global and local uncertain environments due to continuously changing geopolitical and social conditions, and to present new research results in the areas of decision-making mechanisms in the energy markets and energy pricing, smart networks design and management, environmental and energy efficiency analysis. In summary, the papers in this issue touch upon a range of central topics in the fields of energy and related markets, pointing at major existing and future energy and environmental challenges. All these stimulating views provide both policymakers and market participants with the utmost important research output for policy development and monitoring purposes.
