Iran as an energy-rich country faces many challenges in optimal utilization of its vast resources. High population and economic growth, generous subsidies program, and poor resource management have contributed to rapidly growing energy consumption and high energy intensity for the past decades. The continuing trend of energy consumption will bring about new challenges as it will shrink oil exports revenues restraining economic activities and lowering standard of living. This study intends to tackle some of the important challenges in the energy sector and to explore alternative scenarios for utilization of energy resources in Iran for the period 2005-2030. We use techo-economic or end-use approach along with econometric methods to model energy demand in Iran for different types (fuel, natural gas, electricity, and renewable energy) in all sectors of the economy (household, industry, transport, power plants, and others) and forecast it under three scenarios: Business As Usual (BAU), Efficiency, and Renewable Energy.
This study is the first comprehensive study that models the Iranian energy demand using the data at different aggregation levels and a combination of methods to illuminate the future of energy demand under alternative scenarios. The results of the study have great policy implications as they indicate a huge potential for energy conservation and therefore additional revenues and emission reduction under the efficiency scenario compared with the base scenario. Specifically, the total final energy demand under the BAU scenario will grow on average by 2.6 percent per year reaching twice the level as that in 2005. In contrast, the total final energy demand in the Efficiency scenario will only grow by 0.4 percent on average per year. The average growth of energy demand under the combined Efficiency and Renewable Energy scenarios will be 0.2 percent per year. In the BAU scenario, energy intensity will be reduced by about 30 percent by 2030, but will still be above today's world average. In the Efficiency scenario, however, energy intensity will decline by about 60 percent by 2030 to a level lower than the world average today. The energy savings under the Efficiency and Renewable scenarios will generate significant additional revenues and will lead to 45 percent reduction in CO2-emissions by 2030 as compared to the BAU trends.

The North African countries Morocco, Algeria, Tunisia, Libya and Egypt have been and are currently experiencing rapid growth in energy demand. This development confronts their political leaders with the question of how to expand or diversify their countries' generation capacities. In this context, renewable energies and nuclear power constitute options that have rarely been exploited so far in the region. This article analyzes the drawbacks and benefits of both alternatives, with a special focus on import and export dynamics. When attempting to make the strategic decision between renewables and atomic power, North African regional specifics and circumstances have to be taken into account. Hence, in a first step, the article characterizes the energy systems of the North African countries and presents scenarios for their future development. In a second step, it scrutinizes the energy challenges these states face in terms of domestic concerns and foreign affairs. Finally, a case study of Algeria is used to demonstrate how renewable energies, but not nuclear power, are able to respond to North African energy challenges.

Erdgas - die Brücke ins regenerative Zeitalter : Hintergrundbericht im Auftrag von Greenpeace
(2011)
Fünf Jahre bevor die Millennium Development Goals 2015 erreicht werden sollen, sind angesichts der Probleme der "entwickelten" Staaten durch die Finanz- und Wirtschaftskrise nachhaltige Entwicklungsperspektiven für den globalen Süden in den Hintergrund getreten. Doch gerade jetzt, in dieser globalen Umbruchphase, ist das Thema nachhaltige Entwicklung von herausragender Relevanz. Der vorliegende Band analysiert die Bedeutung und die Facetten der ökologischen, sozialen und ökonomischen Nachhaltigkeit, zeigt strukturelle Herausforderungen für eine nachhaltige Entwicklung auf und diskutiert deren Förderung durch internationale Zusammenarbeit. Dabei nähern sich Experten, Wissenschaftler und Praktiker aus der Entwicklungszusammenarbeit aus verschiedenen Blickwinkeln einzelnen Aspekten des komplexen Themenfelds an. Auf diese Weise befasst sich der Sammelband mit den wichtigsten Konzepten und drängendsten strukturellen Problemen aktueller Entwicklungspolitik.

Biogas and bio-methane that are based on energy crops are renewable energy carriers and therefore potentially contribute to climate protection. However, significant greenhouse gas emissions resulting from agricultural production processes must be considered, mainly resulting from agricultural production processes, as fertilizer use, pesticide etc.
This paper provides an integrated life cycle assessment (LCA) of biogas (i.e. bio-methane that has been upgraded and injected into the natural gas grid), taking into account the processes of fermentation, upgrading and injection to the grid for two different types of biogas plants thus examining the current state of the art as well as new, large-scale plants, operated by industrial players. Not only technical and engineering aspects are taken into account here, but also the choice of feedstock which plays an important role as to the overall ecological evaluation of bio-methane.
The substrates evaluated in this paper - aside from maize - are rye, sorghum, whole-crop-silage from triticale and barley, and the innovative options of agricultural grass (Landsberger Gemenge, a mixture of hairy vetch (vicia villosa), crimson clover (trifolium incarnátum) and Italian ryegrass (lolium multiflorum)) as well as a combination of maize and sunflower.
