Demand-side management strategies and the residential sector: lessons from the international experience
No full textTools and policies to promote decarbonization of the electricity sector
No full textThis chaptersummarisesboth marketand non-market-basedpolicies andtoolsavailable forencouragingdecarbonisationof the electricity sector.Market-based policiesinclude carbon pricing, through a carbon tax on electricity generation or a cap-and-trade program on emissions, and second-best tradable standards, which include emissions intensity standards, clean energy standards, and renewable portfolio standards.Popular non-market, technology-specific policymechanismsdiscussed include targeting specific technologies through subsidies, or discouraging the use of dirtier resources, such as coal, through a mandated phase-out. Policy options for encouraging energy efficiency in the power sector to reduce emissions are also explored.Policies that price carbon are more economically efficient than other, particularly non-market policies but can be politically challenging.Since multiple policies are often used simultaneously, interactions between these various market and non-marketpoliciesare discussed. Examples are drawn from experiences in several countries, including parts of Europe, the US, Asia, and South America.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Energy scenarios and implications for future electricity demand
No full textThis chapter sets out four energy scenarios for Great Britain in 2050 that are intended, as a set, to provide insight, assist strategic planning and promote discussion on future electricity networks and the electricity system as a whole. These scenarios were originally prepared by members and associates of the SuperGen FlexNet consortium for Ofgem in the context of their Long-Term Electricity Network Scenarios (LENS) project and benefited from several rounds of stakeholder consultation, workshops and peer review
Electricity Distribution Networks: Investment and Regulation, and Uncertain Demand
Get PDFElectricity distribution networks are capital intensive systems and timely investments are crucial for long-term reliability of their service. In coming years, in the UK, and elsewhere in Europe, many networks are in need of extensive investments in their aging assets. Also, aspects of energy policy concerning climate change, renewable energy, energy
efficiency, demand side management (DSM), network energy loss reduction, quality of service standards, and security of supply require active, flexible, and smart networks that can be achieved through investments. This paper is a chapter in the forthcoming book "Jamasb T. and Pollitt, M. G. (2011) Eds., The Future of Electricity Demand: Customers, Citizens and
Loads, Cambridge University Press: Cambridge" and describes a network investment assessment model developed as a tool to identify and assess the investment requirements of distribution networks. A broadening of the scope of network investments to include demand-related measures that can reduce the need for investments
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
