Abstract

Syftet med denna översiktsrapport är att ge en nulägesbild av möjligheterna till storskalig reducering av koldioxidutsläpp och atmosfäriska koldioxidkoncentrationer genom olika former av NET (Negative Emission Technologies). Enligt 2014 års basscenario från IPCC för maximalt 2°C uppvärming måste de globala koldioxidutsläppen börja minska kraftigt i närtid samt att olika former av NET tas i bruk senast under åren 2030–2045. NETs kritiska roll för måluppfyllnad kan ses i IPCCs scenariodatabas. Utav de 113 scenarier associerade med utfall under 2°C förutsätter 107 av dessa en framgångsrik implementering och storskaligt upptagande av koldioxid både ur själva atmosfären och direkt från olika typer av utsläppskällor. Vår övergripande slutsats är att utifrån nuläget på den tekniska utvecklingen kommer 2 graders målet svårligen uppnås. För att nå måluppfyllnad behövs en kontinuerlig minskning av absoluta utsläpp, att en marknad skapas för koldioxid och en betydligt snabbare utvecklingstakt vad gäller NET, exempelvis genom ökat statligt R&D.

Abstract

The purpose of this paper is to establish if Marshallian and Jacobian knowledge spillovers affect job creation in the green energy sector. Whether these two effects exist is important for the number of jobs created in related fields and jobs pushed away in other sectors. In the analysis, the production efficiency, in terms of jobs and job spillovers, from inventions in solar, wind and energy efficiency, is explored through data envelopment analysis (DEA), based on the Malmquist productivity index, and tobit regression. A panel dataset of American and European firms over the period of 2002–2017 is used. The contribution to the literature is to show the role of the spillovers from the same technology sector (Marshallian externalities), and of the spillovers from more diversified activity (Jacobian externalities). Since previous empirical evidence concerning the innovation effects on the production efficiency is yet weak, the paper attempts to bridge this gap. The empirical findings suggest negative Marshallian externalities, while Jacobian externalities have no statistical impact on the job creation process. The findings are of strategic importance for governments who are developing industrial strategies for renewable energy.

An Anatomy of Failure – Wind Power Development in China

Abstract

China is currently the world’s largest installer of wind power. However, with twice the installed wind capacity compared to the United States in 2015, the Chinese produce less power. The question is: Why is this the case? This article shows that Chinese grid connectivity is low, Chinese firms have few international patents, and that export is low even though production capacity far exceeds domestic production needs. Using the tools of Austrian economics, China’s wind power development from 1980 to 2016 is documented and analyzed from three angles: (a) planning and knowledge problems, (b) unproductive entrepreneurship, and (c) bureaucracy and government policy. From a theoretical standpoint, both a planning problem and an entrepreneurial problem are evident where governmental policies create misallocation of resources and a hampering of technological development.

Government Support to Renewable Energy R&D: Drivers and Strategic Interactions among EU Member States

Abstract

Although the climate challenge requires proactive policies that spur innovation in the renewable energy sector, various countries commit vastly different levels of support for renewable energy R&D. This paper addresses the question why this may be the case. Specifically, the objective is to analyse the determinants of government support to renewable energy R&D in the European Union (EU), and, in doing this, we devote particular attention to the question of whether the level of this support tends to converge or diverge across EU Member States. The investigation relies on a data set of 12 EU Member States and a bias-corrected dynamic panel data estimator. We test for the presence of conditional β-convergence, and the impacts of energy dependence and electricity regulation on government R&D efforts. The findings display divergence in terms of government support to renewable energy R&D, and this result is robust across various model specifications and key assumptions. The analysis also indicates that countries with a low energy-import dependence and deregulated electricity markets tend to experience lower growth rates in government renewable energy R&D. The paper ends by discussing some implications of the results, primarily from an EU perspective.
