The adoption of green energy technologies: The role of policies in Austria, Germany, and Switzerland
2017
We contribute to the existing research about policy-induced technology adoption in several ways. First, we suggest a new survey design to measure the energy-related policy environment. Second, we simultaneously estimate the policy effects for the adoption propensity and the adoption intensity simultaneously and, third, we compare the policy effects in the three countries, Austria, Germany, and Switzerland. Based on a representative sample of firms for all three countries we find that policies essentially promote the adoption of technologies and they are practically ineffective for the intensity, which poses a great challenge to future policy designs. Voluntary agreements or demand-related f…

A Survey on Technologies Which Make Bitcoin Greener or More Justified
2022
According to recent estimates, one bitcoin transaction consumes as much energy as 1.5 million Visa transactions. Why is bitcoin using so much energy? Most of the energy is used during the bitcoin mining process, which serves at least two significant purposes: a) distributing new cryptocurrency coins to the cryptoeconomy and b) securing the Bitcoin blockchain ledger. In reality, the comparison of bitcoin transactions to Visa transactions is not that simple. The amount of transactions in the Bitcoin network is not directly connected to the amount of bitcoin mining power nor the energy consumption of those mining devices; for example, it is possible to multiply the number of bitcoin transactio…
Resource Allocation and Computation Offloading for Multi-Access Edge Computing With Fronthaul and Backhaul Constraints
2021
Edge computing is able to provide proximity solutions for the future wireless network to accommodate different types of devices with various computing service demands. Meanwhile, in order to provide ubiquitous connectivities to massive devices over a relatively large area, densely deploying remote radio head (RRH) is considered as a cost-efficient solution. In this work, we consider a vertical and heterogeneous multi-access edge computing system. In the system, the RRHs are deployed for providing wireless access for the users and the edge node with computing capability can process the computation requests from the users. With the objective to minimize the total energy consumption for proces…
Which firms benefit from investments in green energy technologies? : The effect of energy costs
2019
Abstract Firms will invest in green energy technologies only if these investments have an economic pay-off. Based on unique firm-level data from Austria, Germany, and Switzerland, we find that the marginal effect of investments in green energy technologies on productivity is positive only for the 19% of firms with the highest energy costs. These results have major implications for companies and policy makers regarding the design of green energy policies and incentives.

Multicriteria Decision Aiding for Planning Renewable Power Production at Moroccan Airports
2022
This study is about multicriteria decision aiding (MCDA) for the green airports program of the Moroccan Airport Authority ONDA. The goal of the program is to develop significant amounts of renewable power at airports. In particular, ONDA wants to select airports at which large solar and wind power parks should be built. Multiple criteria, including economy, technical feasibility, and environmental concerns, must be considered simultaneously. In this study, we apply Stochastic Multicriteria Acceptability Analysis (SMAA) for ranking the candidates to be developed into green airports. The analysis is conducted in phases with different sets of criteria. This study is the first application of MC…
Tiellä kohti uusien energiateknologioiden kaupallistumista : eri toimijoiden näkemyksiä puubiomassaa polttoaineenaan käyttävien pien- ja mikro-kokolu…
2011
Tässä laadullisessa tutkimuksessa selvitettiin puubiomassaa polttoaineenaan käyttävien pien- ja mikro-kokoluokan CHP-teknologioiden innovaatioprosessiin, erityisesti kaupallistamiseen ja markkinoilla yleistymiseen, liittyviä edistämistekijöitä ja esteitä. Tutkimusaineisto koottiin haastattelemalla 10 eri toimijaa, jotka edustivat kattila- ja laitevalmistajia, korkeakouluja, tutkimuslaitoksia, julkisia rahoittajia sekä kehitysyhtiöitä. Haastateltavilta kysyttiin heidän näkemyksiään tarkasteltavien energiateknologioiden innovaatioprosessiin vaikuttavista edistämistekijöistä ja esteistä viidestä eri näkökulmasta: poliittisesta, taloudellisesta, sosiaalisesta, teknologisesta ja ympäristötekijöi…
