In alignment with the European Union's legislation, Greece submitted its final 10-year National Energy and Climate Plan (NECP) in December 2019, setting more ambitious energy and climate targets than those originally proposed in the draft version of the document. Apart from higher penetration of renewable energy sources (RES), the final NECP projects also zero carbon use in power generation till 2030. Although decarbonization has long been regarded beneficial for economies that base their energy production on coal, as it is the case with Greece, the macroeconomic and societal ramifications of faster transitions to carbon-free economies remain highly unexplored. Under this context, in this paper, we soft-link energy models, namely Times-Greece and Primes, with a macroeconomic model, namely Global Trade Analysis Project (GTAP), to measure the effects of the final and draft NECPs on the Greek economy and evaluate the impact of higher decarbonization speeds. We find that the faster transition scenario displays both economic and societal merits, increasing Gross Domestic Product (GDP) and household income by about 1% and 7%, respectively.

Significant renewable energy (RE) investments have to be implemented in order to achieve the ambitious RE targets set in the EU for 2020 and beyond. Moreover, a great amount of capital has to be leveraged, as these projects are followed by high investment and financing costs. Main aim of this paper is the provision of a comprehensive assessment of the existing risk elements of RE investments in relation to the respective policies and the evaluation of their impact on the weighted average cost of capital (WACC) in Greece. A consultation procedure with key national energy stakeholders took also place, including policy makers, project developers, investors, equity providers, bankers and energy analysts in the Greek RE market, in order to provide a validation of the respective results. It has been concluded that the policy design risk represents the risk element with the greatest impact on the cost of capital and, thus, the level of RE investments' deployment. Βased on the cost of capital valuation process followed, the WACC was estimated to reach approximately 12% for onshore wind and little lower values for solar PV projects in Greece. ; This work was supported by the Intelligent Energy Europe (IEE) Programme within the framework of the project "DIA-CORE - Policy dialogue on the assessment and convergence of RES policies in EU Member States" (Project Number: IEE/12/833/SI2.645735), the Horizon 2020 Programme of the European Commission in the context of the project "TRANSrisk - Transitions pathways and risk analysis for climate change mitigation and adaptation strategies" (Grant Agreement No. 642260) and the European Climate Foundation within the framework of the Pricetag project (Project Number: EPONL17190).

Part 8: Management, Policies and Technologies in e/m-Services ; International audience ; E-government benchmarking is being conducted by various organizations but its assessment is based on a limited number of indicators and does not highlight the multidimensional nature of the electronically provided services. This paper outlines a multicriteria evaluation system based on four points of view: (1) infrastructures, (2) investments, (3) e-processes, and (4) users' attitude in order to evaluate European Union countries. In this paper, twenty one European Union countries are evaluated and ranked over their e-government progress. Their ranking is obtained through an additive value model which is assessed by an ordinal regression method and the use of the decision support system MIIDAS. In order to obtain robust evaluations, given the incomplete determination of inter-criteria model parameters, the extreme ranking analysis method, based on powerful mathematical programming techniques, has been applied to estimate each country's best and worst possible ranking position.

In the current competitive environment, each company faces a number of challenges: quick response to customers' demands, high quality of products or services, customers' satisfaction, reliable delivery dates, high efficiency, and others. As a result, during the last five years many firms have proceeded to the adoption of enterprise resource planning (ERP) solutions. ERP is a packaged software system, which enables the integration of operations, business processes and functions, through common data‐processing and communications protocols. However, the majority, if not all, of these systems do not support the production scheduling process that is of crucial importance in today's manufacturing and service industries. In this paper, the authors propose a knowledge‐based system for production‐scheduling that could be incorporated as a custom module in an ERP system. This system uses the prevailing conditions in the industrial environment in order to select dynamically and propose the most appropriate scheduling algorithm from a library of many candidate algorithms.

Investing in energy efficiency (EE) could play a crucial role in transitioning to a future economy, where sustainable growth will be the centre of attention. To reach such EE investments, a mobilisation of capital through the targeted use of funds, innovative schemes and standardisation tools for the respective key actors is required. The European Union Horizon 2020 Triple-A project could assist in securing EE investments that could meet their financial commitments. This manuscript provides a standardised methodology and tools to assess the involved risks and benchmarks the proposed investment ideas, helping investors and policymakers choose the most profitable solution. This manuscript summarises the methodology established, tools developed, and results that emerged from Triple-A's venture to mainstream EE financing. View Full-Text
