Vindenergi

Vi ved det godt: Klimakrisen er tidens største politiske, sociale og økonomiske problem. Vores afhængighed af fossile brændsler risikerer reelt at blive menneskehedens endeligt. Vi skylder fremtidige generationer at sætte alt ind for at reducere udledningen af drivhusgasser. Lige nu. Men glem alt dette et øjeblik. Det grønne pengetræ er hverken en appel til din dårlige samvittighed eller dit varme hjerte. Bogens altoverskyggende argument er kynisk: Vi skal sætte tryk på den grønne omstilling, fordi der er gode penge at tjene på den. Vi skal erstatte det fossile med grønt, fordi det er en guldrandet forretning for danske virksomheder, almindelige lønmodtagere og din privatøkonomi.Igennem interviews med alt fra topchefer til havnearbejdere og atomfysikere, understreger Magnus Barsøe det imponerende potentiale inden for de grønne investeringer. Han kommer med politiske forslag, der kan sætte skub i den grønne omstilling og leverer en bredside til venstrefløjens vækstkritikere. Og han tager fat på et af de mest kontroversielle emner i klimadebatten: atomkraft.

As such, ETA2023 aims at bringing experts and future leaders together to forge more efficient ways to engineer and live. In other words, ETA2023 strives to synergise and catalyse all stakeholders, enthusiasts, and experts from academia, industry, policy arenas, and the general public, to formulate novel ways to improve tomorrow.This symposium will disseminate recent progress and promote collaborations to maximize opportunities for innovative integrated solutions. Topics of interest include resource and energy efficiency, waste reduction, and eco-friendly agriculture, architecture, engineering, and living.

This book shows possible solutions to how a profitable energy supply can be implemented with almost no population resistance. Worldwide, more than 80 % of our energy needs are still covered by fossil fuels. Under these circumstances, can climate change still be stopped?Essential technologies for usage of wind energy with an emphasis on high-altitude wind utilization are presented. Airborne wind energy is one of the most promising technologies to enable a renewable energy turnaround in an economical way. The main problem of conventional renewable energy is the insufficient availability. To ensure a 100 % supply of renewable energy, enormous and very expensive storage capacities would have to be built up.How we can cover our entire energy needs (electricity, mobility and heat) in the future without fossil fuels, without risking the competitiveness of our economy, is shown in this book.

In diesem Buch werden die Grundlagen für die Ermittlung von Kurzschlussströmen behandelt. Die Berechnung der Ströme gehört mit zu den wesentlichen Aufgaben bei der Planung elektrischer Netze. Da die Netze zuverlässig und sicher betrieben werden müssen, ist die Berechnung durch internationale und nationale Normen standardisiert. In der gültigen IEC/VDE-Norm werden konkrete Rechenverfahren angewendet, die sich in vielen Jahrzehnten bewährt haben. Hierbei werden neue technische Entwicklungen laufend ergänzt. Vielfach sind jedoch die Hintergründe nicht mehr bekannt, so dass in diesem Buch diese Grundlagen beschrieben werden. Der Autor ist seit 1972 in der Normung der Kurzschlussstromberechnung tätig und hat die in dieser Zeit gewonnen Erkenntnisse zusammengetragen.

Der Glaube an die Machbarkeit der sogenannten Energiewende durch die volatilen Energieerzeuger Windkraft und Photovoltaik wird genährt durch das trügerische Arbeiten mit Mittelwerten, das Täuschen mit statistischen Falschangaben sowie das Weglassen wichtiger Konsequenzen.Auch der Umgang mit den Größenordnungen und die Umrechnung zwischen Mega, Giga, Tera bereitet vielfach etliche Probleme und führt daher zu unglaublichen Trugschlüssen in Bezug auf die Machbarkeit und Durchführung der Energiewende, ganz zu schweigen von den technischen und ökonomischen Konsequenzen.Die gegenwärtig beschrittenen Wege führen in ein unausweichliches Chaos, nämlich den Verlust einer zuverlässigen und bezahlbaren Energieversorgung, die für eine Industrienation unverzichtbar ist.Im vorliegenden Buch möchten die Autoren die Leser durch sorgfältig beschriebene Analysen auf der Basis von Daten offizieller Stellen mitnehmen, damit sie sich ein eigenes Urteil über die sogenannte Energiewende und deren Konsequenzen bilden können.

The continuous increase of wind power penetration levels in Egypt makes wind a critical component of power generation in the grid.

This book examines the characteristics and opportunities for farm energy in the northeast quadrant of the United States, with attention to energy use, strategic energy management, and energy production by solar, wind, biomass, and other means. Throughout, the distinct characteristics of the region and their impact on energy solutions are discussed, and the outlook for future energy strategies is considered. Farm energy production and use are topics of increasing interest, as the need for improved efficiency and the opportunity for sustainable energy production both drive agricultural enterprises to reduce energy use and pursue opportunities for renewable energy production and use on the farm. However, the unique regional characteristics of agriculture make it challenging to apply a single approach to all situations.
