Social Acceptance and the Development of the North Sea Offshore Grid
© Lexxion Verlagsgesellschaft mbH (8/2013)
This article considers social acceptance and the development of marine renewable energy and grid infrastructure for a sustainable, secure, and competitive European energy future. The North Seas Countries Offshore Grid Initiative and the European Union’s Regulation on Guidelines for Trans-European Energy Infrastructure are considered in this respect. Declarations and recent marine initiatives of the Renewables- Grid-Initiative are examined to determine how they might support the development of greater social acceptance for marine grid infrastructure for the northern seas of Europe. Finally, recommendations are made for a regulatory framework to support the development of social acceptance for offshore grid infrastructure in these seas.

Overview of Material and Energy Flows in German Wastewater Infrastructures
© DIV Deutscher Industrieverlag GmbH / Vulkan-Verlag GmbH (9/2012)
Today, Germany is moving to more sustainable energy systems. This challenges also the wastewater sector to improve energy balances of infrastructures. Besides energy efficiency, also reuse of resources from wastewater offers large energy potentials. While Germany represents a best practice example for wastewater management within the technical paradigm, there are large opportunities for energetic reuse of wastewater resources, which are not yet fully exploited. The purpose of this paper is to give an overview of material and energy flows in wastewater infrastructures in Germany today, and to present two eco-innovations for improved energy balances. Making full use of synergies between energy and (waste)water infrastructures is an important feature of sustainable cities of tomorrow.

Renewable Energy from the Ocean and Tides: A Viable Renewable Energy Resource in Search of a Suitable Regulatory Framework
© Lexxion Verlagsgesellschaft mbH (12/2009)
Over the past few years there has been significant international interest in the development of offshore wind energy as a source of renewable energy especially in Europe. However, the wind is not the only source of renewable energy in offshore areas. The broad suite of technologies collectively known as ocean energy are also beginning to emerge as a viable base-load source of renewable energy. Ocean energy technology involves a wide range of engineering technologies that are able to obtain energy from the ocean using a variety of conversion mechanisms including hydrokinetic energy (where the energy of ocean (or fluvial) currents and tides is captured by devices which are installed under the surface of the water); wave energy (where the energy of the surface wind waves is used to produce electricity by a variety of devices installed on the surface of the sea); ocean thermal energy or OTEC (which uses the temperature differential between cold water from the deep ocean and warm surface water) and; Osmotic energy (which relates to the pressure differential between salt and fresh water).

Energy research, environment, applications and sustainable development
© Aristotle University of Thessaloniki (6/2009)
Power from natural resources has always had great appeal. Coal is plentiful, though there is concern about despoliation in winning it and pollution in burning it. Nuclear power has been developed with remarkable timeliness, but is not universally welcomed, construction of the plant is energy-intensive and there is concern about the disposal of its long-lived active wastes. Barrels of oil, lumps of coal, even uranium come from nature but the possibilities of almost limitless power from the atmosphere and the oceans seem to have special attraction. The wind machine provided an early way of developing motive power. The massive increases in fuel prices over the last years have however, made any scheme not requiring fuel appear to be more attractive and to be worth reinvestigation.

Sustainable energy: challenges of implementing new technologies in Sudan
© Aristotle University of Thessaloniki (6/2009)
Sudan is an agricultural country with fertile land, plenty of water resources, livestock, forestry resources and agricultural residues. An overview of the energy situation in Sudan is introduced with reference to the end uses and regional distribution. Energy sources are divided into two main types; conventional energy (petroleum products, and electricity); and non-conventional energy (biomass, solar, wind, hydro, etc.).

From the old archimedean screw pumps to the new archimedean screw turbines for hydropower production in Greece
© Aristotle University of Thessaloniki (6/2009)
The main aim of this paper is to present the unconventional small hydro philosophy of recovering the unexploited hydraulic energy of Greek watercourses by using the Archimedean screw turbines small hydropower plants.What is new in the present paper is the inversion of the energy flow in its operation, turns the old Archimedean’s screw pump into a new Archimedean screw turbine, a powerful hydropower generator for the extraction of hydraulic energy.

Construction of small hydropower plants for renewable energy production and the use of storage basins for water reclamation
© Aristotle University of Thessaloniki (6/2009)
The construction of a Small Hydro Power Plant (SHP) depends on the discovery of suitable places for water flow quantities and heights. Storage basins are necessary to appropriate places for the creation of falls and flows, through rain water collection. Hydrological research is necessary, for the place, the height and the kind of a dam construction (earth, concrete) at the selected site.

Waste combustor ash utilization
© WTERT Greece (5/2009)
The incorporation of municipal solid waste combustor (MWC) ash into bituminous pavements has been investigated in the United States since the middle 1970s. Thus far, most, if not all of these projects, have attempted to answer the questions: Is it safe? Is it feasible? Or does it provide an acceptable product?
