    The Renewable Energy Landscape Energy The Renewable ‘Long overdue, this guide on how to place renewable energy in the landscape to maximize public acceptance is critical to the energy transition that is so desperately needed.’ Paul Gipe, early advocate of aesthetic design for wind and solar power plants, author of Wind Energy for the Rest of Us: A Comprehensive Guide to Wind Power and How to Use It. ‘Instrumental reading for those that want an energy future that is not only sustainable and affordable, but inclusive and just. If we are to achieve public support for a sustainable energy future, we must minimize natural public resistance to change. This book shows how to do it.’ Benjamin K. Sovacool, Professor of Energy Policy, University of Sussex, UK The Renewable Energy The Renewable Energy Landscape is a definitive guide to understanding, assessing, avoiding, and minimizing scenic impacts as we transition to a more renewable energy future. It focuses attention, for the first time, on the unique challenges solar, wind, and geothermal energy will create for landscape protection, planning, design, and management. Landscape Topics addressed include: • Policies aimed at managing scenic impacts from renewable energy development Preserving scenic values in our sustainable future and their social acceptance within the USA, Canada, Europe and Australia • Visual characteristics of energy facilities, including the design and planning techniques for avoiding or mitigating impacts and improving visual fit • Methods for assessing visual impacts of energy projects and the best practices for creating and using visual simulations • Policy recommendations for political and regulatory bodies. A comprehensive and practical book, The Renewable Energy Landscape is an essential resource for those engaged in planning, designing, or regulating the impacts of these new, critical energy sources, as well as a resource for communities that may be facing the prospect of development in their local landscape.

    Analysis of the French Wind Power Industry: Employment, the Market and the Future of Wind Power

    Analysis of the French wind power industry: employment, the market and the future of wind power October 2018 Every year, France Énergie Éolienne hosts the National Wind Power Congress (Colloque National Éolien), a key event in the industry. The 9th edition, to be held on 17 and 18 October 2018, will focus on innovation. The theme of the congress is “Energy Transition: Wind Power at the Heart of the Regions”. Wind Observatory. © 2018 BearingPoint France SAS | 3 Foreword France has set itself ambitious renewable energy targets: by 2030, 32% of total national energy use must come from renewable sources, with 40% of electricity coming from renewable sources. Both offshore and onshore wind power will play a key role in France’s energy transition. France had a grid-connected onshore wind capacity of 13.5 GW as of the end of 2017, against a target of 15 GW by the end of 2018, set by the multiannual energy plan (Programmation pluriannuelle de l’énergie – PPE). The PPE has also set a target of 21.8–26.0 GW capacity by the end of 2023. As the first PPE deadline approaches, the revision of this energy policy instrument should reaffirm the ambitious targets of the wind industry. Even though results are in line with the expected trajectory, the French government will continue to provide strong support for the wind industry. I am convinced that we still have much we can do to ensure the achievement of our goals. The first year of Emmanuel Macron’s presidency has demonstrated the government’s strong commitment to renewable energies.

    Distributed Small­Scale Wind in New Zealand: Advantages, Barriers and Policy Support Instruments A dissertation submitted in partial fulfilment of the requirements for the Degree of Master of Environmental Studies at Victoria University of Wellington By Martin Barry Victoria University of Wellington 2007 “If we want things to stay as they are, things will have to change” Giuseppe di Lampedusa, 1896 – 1957 ii ACKNOWLEDGEMENTS I would like to extend warm thanks to the following people who made contributions to this paper. To my supervisor Associate Professor Ralph Chapman, who gave up considerable amounts of his time for consultation, and provided solid support and guidance on pulling this thing together. Jesse Nichols and Philippa Le Couteur who gladly assisted with proofreading and editing, Ben Gleisner, who helped conceptualise the structure and layout, and to Clive Anstey who provided the frontispiece photo. Also, to those who helped with the rural survey. Ben Aicken, who created the photomontages and Colleen Kelly who helped with the statistical analysis. Finally, the School of Geography, Environment and Earth Sciences, and Greenpeace New Zealand, who provided the funding that made the survey possible. iii ABSTRACT Despite having one of the best wind resources in the world, New Zealand’s wind energy industry is growing at a slower rate than the OECD average. This is arguably due to a lack of appropriate government support, with industry development largely being left to the market. These conditions have created a wind industry with the following four characteristics: a trend toward large­scale wind farms (leading to increased local opposition), a small number of investors, a high geographic concentration of wind capacity and a limited local turbine manufacturing industry.

The help of all my coworkers was also much appreciated and I would like to thank them all: Xavier Gray, Quentin Chiron, Alexander Fredj, Sebastien Bonnaval, François Rousseau, Boris Golotchoglou, Julie Boulo and Ombeline Accarion. Their availability, their enthusiasm and pedagogy made of this master thesis a rich professional, academic and personal experience, even creating new friendships. I also particularly thank Camille Hamon for his advices as supervisor during the writing of this master thesis and Björn Palm for being my examiner. i Abstract Despite all environmental and economic advantages of wind power, noise emission remains an issue for population acceptance. In France, the current noise emission regulation defines noise emergence level thresholds, leading to wind turbine curtailment. Great energy generation losses and thus lost revenues are at stake. This master thesis presents current acoustic campaigns conducted for the development of a wind power project in France and proposes acoustic model improvements to predict curtailment losses before the construction of the wind farm.

  • 2019 Wind Observatory

    2019 WIND OBSERVATORY Analysis of the French wind power industry: market, jobs and challenges APPENDIXES CHALLENGES JOBS MARKET 2 Foreword The French energy landscape is gradually shifting towards renewable energies. Ambitious targets have been set, aiming to increase the share of renewables to 33% of the energy mix and 40% of power generation by 2030. Wind power clearly stands out, as a key sector, alongside solar energy, faced with new challenges and offering high expectations. As the Multiannual Energy Programming is about to be disclosed, wind power (both onshore and offshore), is regarded as one of the cornerstones of the energy transition in the French power mix. Over the past year, wind power has indeed covered 6% of France’s power needs. The industry has also demonstrated its competitiveness in relation to the latest calls for tenders, specifically with regards to the wind farm awarded off Dunkirk. In this buoyant context, wind energy is also a major driver of regional economic development and employment, with a 6.4% increase in jobs in 2018. The industry must, however, continue to improve project integration in terms of local territories, the environment, and the landscape. The current development dynamic is confirmed in the Multiannual Energy Programming, which sets ambitious targets for 2028 through the installation of the first offshore wind farms. The French Parliament has scaled up its ambitions in terms of the development of offshore wind power generation and now aims to award 1 GW per year by 2024. APPENDIXES CHALLENGES JOBS MARKET 3 Foreword The industry can count on the support of the French Government.
