Electricity from renewable sources of energy is plagued by fluctuations (due to variations in wind strength or the intensity of insolation) resulting in a lack of stability if the energy supplied from such sources is used in 'real time'. An important solution to this problem is to store the energy electrochemically (in a secondary battery or in hydrogen and its derivatives) and to make use of it in a controlled fashion at some time after it has been initially gathered and stored. Electrochemical battery storage systems are the major technologies for decentralized storage systems and hydrogen is the only solution for long-term storage systems to provide energy during extended periods of low wind speeds or solar insolation. Future electricity grid design has to include storage systems as a major component for grid stability and for security of supply. The technology of systems designed to achieve this regulation of the supply of renewable energy, and a survey of the markets that they will serve, is the subject of this book. It includes economic aspects to guide the development of technology in the right direction. Provides state-of-the-art information on all of the storage systems together with an assessment of competing technologies; Features detailed technical, economic and environmental impact information of different storage systems; Contains information about the challenges that must be faced for batteries and hydrogen-storage to be used in conjunction with a fluctuating (renewable energy) power supply.

Sugarcane: Agricultural Production, Bioenergy and Ethanol explores this vital source for ""green"" biofuel from the breeding and care of the plant all the way through to its effective and efficient transformation into bioenergy. The book explores sugarcane's 40 year history as a fuel for cars, along with its impressive leaps in production and productivity that have created a robust global market. In addition, new prospects for the future are discussed as promising applications in agroenergy, whether for biofuels or bioelectricity, or for bagasse pellets as an alternative to firewood for h

HauptbeschreibungWerbung ist heutzutage ein nicht mehr wegzudenkender Bestandteil unseres Alltags. Sie begegnet uns ständig und überall, wir können uns ihr nicht entziehen. Auch aus wirtschaftlicher Sicht hat die Werbung, mit jährlichen Ausgaben der deutschen Unternehmen von ca. 30 Mrd. Euro, eine große Bedeutung. Doch wie sieht es in Bezug auf die erneuerbaren Energien mit der Werbung aus? Der Sektor boomt. Trotzdem kommt man als Otto Normalverbraucher selten mit Werbung aus diesem Bereich in Berührung.Zielstellung der Studie ist es, Werbeanzeigen für erneuerbare Energien aus l
