Die Ökodesign-Richtlinie (Richtlinie 2009/125/EG des Europäischen Parlaments und des Rates vom 21. Oktober 2009 zur Schaffung eines Rahmens für die Festlegung von Anforderungen an die umweltgerechte Gestaltung energieverbrauchsrelevanter Produkte) trat im Jahre 2005 in Kraft und wurde im Jahr 2009 revidiert und erweitert. Die Richtlinie zielt auf Verbesserungen des Designs energieverbrauchsrelevanter Produkte mit dem Ziel einer Reduktion der Umweltbelastungen unter Berücksichtigung aller Phasen des Produktlebenszyklusses. So sind bereits im Rahmen dieser Richtlinie beispielsweise Mindestenergieeffizienzanforderungen für bestimmte, auf dem europäischen Markt angebotene Geräte festgelegt worden, die von den Geräteherstellern und -importeuren eingehalten werden müssen.
The Gulf countries are largely dependent on exporting oil and natural gas for their national budgets. They mainly use domestic fossil fuels for their domestic energy supply. In spite of favorable geographic conditions, especially for solar energy, renewable energies are still a niche application. Abu Dhabi, besides Dubai, the most important emirate in the United Arab Emirates (UAE), has now started a process of "transforming oil wealth into renewable energy leadership", and has set the long-term goal of a "transition from a 20th Century, carbon-based economy into a 21st Century sustainable economy." This article is a case study about "Masdar City", a planned carbon-neutral town in Abu Dhabi. The article describes the key characteristics of Masdar City, analyses the drivers behind the project, identifies the main actors for its implementation, and seeks obstacles to creation and development as well as the policy behind Masdar City. Finally, a first judgment of possible diffusion effects of the project is done.
This study provides insight into the feasibility of a CO2 trunkline from the Netherlands to the Utsira formation in the Norwegian part of the North Sea, which is a large geological storage reservoir for CO2. The feasibility is investigated in competition with CO2 storage in onshore and near-offshore sinks in the Netherlands. Least-cost modelling with a MARKAL model in combination with ArcGIS was used to assess the cost-effectiveness of the trunkline as part of aDutch greenhouse gas emission reduction strategy for the Dutch electricity sector and CO2 intensive industry. The results show that under the condition that a CO2 permit price increases from €25 per tCO2 in 2010 to €60 per tCO2 in 2030, and remains at this level up to 2050, CO2 emissions in the Netherlands could reduce with 67% in 2050 compared to 1990, and investment in the Utsira trunkline may be cost-effective from 2020–2030 provided that Belgian and German CO2 is transported and stored via the Netherlands as well. In this case, by 2050 more than 2.1 GtCO2 would have been transported from the Netherlands to the Utsira formation. However, if the Utsira trunkline is not used for transportation of CO2 from Belgium and Germany, it may become cost-effective 10 years later, and less than 1.3 GtCO2 from the Netherlands would have been stored in the Utsiraformation by 2050. On the short term, CO2 storage in Dutch fields appears more cost-effective than in the Utsira formation, but as yet there are major uncertainties related to the timing and effective exploitation of the Dutch offshore storage opportunities.
Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates are major oil and natural gas producing countries that make up the Gulf Cooperation Council. The six GCC countries fall in the top 25 countries of carbon dioxide emissions per capita and are perceived as the main actors blocking international climate change negotiations. The aim of this article is to discuss from a policy perspective the capacities of the GCC states to switch toward an ecological modernization of their energy sectors. At the beginning of the paper, I analyze the benefits of transforming oil wealth into funding for renewable energy and energy efficiency. After this, I discuss obstacles to such a transformation process based on the rentier states theory. Finally, I investigate governance of the GCC on all levels (international, regional, and local). The article shows that the GCC countries have recently adopted a more pro-active approach toward ecological modernization. This reorientation has not yet resulted in the development of consistent strategies and policies, however. The concluding assumption based on the concept of policy transfer is that pioneering projects such as Masdar City and innovative regulation like the green building code in Dubai will spread within the GCC.
Die grundsätzliche wirtschaftstheoretische Kritik am Erneuerbare-Energien-Gesetz greift zu kurz
(2010)
Der volkswirtschaftliche Nutzen der Förderung erneuerbarer Energien in Deutschland über das Erneuerbare-Energien-Gesetz (EEG) wurde wiederholt von verschiedenen Ökonomen und wirtschaftswissenschaftlichen Institutionen in Frage gestellt. Dabei wird zumeist als wesentliches Argument vorgebracht, dass das EEG unnötige Kosten für die Gesellschaft verursache und spätestens seit der EU-weiten Umsetzung eines Handels mit CO2-Emissionszertifikaten überflüssig sei. Eine genauere Betrachtung zeigt, dass diese Argumentation zu kurz greift, nicht zuletzt weil sie wesentliche ökonomische Zusammenhänge vernachlässigt.
