Understanding the factors influencing community acceptance of renewable energy projects such as offshore wind farms is important for achieving a transition to low carbon energy sources. However, to date community acceptance research has concentrated on responses to actual proposals, seeking to explain local objections. ‘Upstream’ research that investigates the ‘place-technology fit’ of a potential renewable energy project before it is proposed is scarce, yet can inform technology deployment by taking local knowledge and preferences into account. We address this gap in a study conducted in Guernsey, Channel Islands. Data was collected using a survey (n = 468) co-designed with island policy makers presenting technical, economic and locational details of a potential offshore wind project. Results show that acceptance of the same project design differed significantly across alternative development locations. Regression analyses compared the roles of personal, context and project-related factors in explaining acceptance for each site. Support for using wind energy for local electricity supply was the most important predictor of acceptance, and this variable mediated the relationship between island energy security and community acceptance. We conclude that place matters for community acceptance and that security and autonomy are co-benefits of local renewable energy projects that deserve further research.

This paper investigates the optimum tidal energy converter array density at a tidal inlet by applying surrogate-based optimisation. The SBO procedure comprises problem formulation, design of experiments, numerical simulations, surrogate model construction and constrained optimisation. This study presents an example for the Faro-Olhão Inlet in the Ria Formosa (Portugal), a potential site for tidal in-stream energy extraction. A 35 kW Evopod™ floating tidal energy converter from Oceanflow Energy Ltd. has been used for array size calculations considering two design variables: (1) number of array rows, and (2) number of tidal energy converter per row. Arrays up to 13 rows with 6–11 tidal energy converters each are studied to assess their impacts on array performance, inlets discharges and bathymetry changes. The analysis identified the positive/negative feedbacks between the two design variables in real case complex flow fields under variable bathymetry and channel morphology. The non-uniformity of tidal currents along the array region causes the variability of the resource in each row, as well as makes it difficult to predict the resultant array configuration interactions. Four different multi-objective optimisation models are formulated subject to a set of performance and environmental constraints. Results from the optimisation models imply that the largest array size that meets the environmental constraints is made of 5 rows with 6 tidal energy converter each and an overall capacity factor of 11.6% resulting in an energy production of 1.01 GWh year−1. On the other hand, a higher energy production (1.20 GWh year−1) is achieved by an optimum array configuration, made of 3 rows with 10 tidal energy converters per row, which maximises power output satisfying environmental and performance restrictions. This optimal configuration permits a good level of energy extraction while having a reduced effect on the hydrodynamic functioning of the multi-inlet system. These results prove the suitability and the potential wide use of the surrogate-based optimisation method to define array characteristics that enhance power production and at the same time respect the environmental surrounding conditions.

Renewable energy and sustainable food production are high on the international agenda, as is the prospect of expanding activity northwards to Arctic waters. In this article, we review core elements of the marine governance systems for aquaculture facilities and offshore wind farms in Norway and Scotland. Management of these sectors through strategic planning, marine spatial planning and licensing systems furthers rule of law values such as stability and predictability, making investment less risky. The review illustrates how the governance systems also facilitate flexibility and adaptability, balancing predictability considerations against the need to adapt management to natural and economic changes and innovative technologies, or even effective multi-use. This article discusses what endeavours have been made to strike a balance between predictability and adaptability in these sectors in Norway and Scotland. This study of marine management regimes in the Arctic and northern parts of the Temperate Northern Atlantic, and the values underpinning these regimes, provides lessons for the future of the Arctic.

Lessons learned from offshore oil and gas incidents in the Arctic and other ice-prone seas

Specific risks to offshore oil and gas operations manifest in the Arctic and other harsh environments. Such extreme operating conditions can disrupt the offshore infrastructure and cause major accidents, posing a great challenge to operators. A thorough investigation of past incidents helps to learn lessons to ensure that a recurrence of serious accidents affecting workers and the environment can be prevented.

The analysis of past incidents is divided into two parts. First, we offer a statistical analysis of offshore incidents triggered by natural events in the Arctic and in similar harsh environments. The analysis, organised by location, cause, and type of damage, failure mechanisms, and consequences, is based on data from the World Offshore Accident Database (WOAD). Second, we analyse a selection of accidents that occurred in the recent past in ice-prone seas, with particular attention to potential deficiencies in safety measures, design requirements and design methodologies, operations planning and component reliability.

Based on the analysis, important lessons were identified which stress the need for further efforts to ensure the safety of workers and of assets and to get all actors involved in offshore operations engaged towards achieving a safer future for the exploitation of oil and gas resources.

Minimizing wildlife impacts for offshore wind energy development: Winning tradeoffs for seabirds in space and cetaceans in time

Although offshore wind energy development (OWED) offers a much-needed renewable energy alternative to fossil fuels, holistic and effective methods for evaluating environmental impacts on wildlife in both space and time have been lacking. The lengthy environmental compliance process, estimated to incur a 7–10 year permitting timeline [1], has been identified as a significant impediment to offshore energy development in U.S. waters. During operation, seabirds can collide and be displaced by turbines. During episodic pre-operation phases, cetaceans are most heavily impacted acoustically by pile driving (and similarly seismic air gun surveys for oil and gas exploration). The varying nature of impacts in space and time leads us to conclude that sites should be selected in space to minimize long-term operational impacts on seabirds, and timing of surveying and construction activities to be conducted in times of the year when sensitive migratory marine mammals are least present. We developed a novel spatiotemporal decision support framework that interactively visualizes tradeoffs between OWED industry profits and wildlife sensitivities, in both space and time. The framework highlights sites on a map that are the most profitable and least sensitive to seabirds. Within the U.S. Mid-Atlantic study area, the New York Call Areas are particularly well optimized for minimal impact on seabirds with maximal profits to OWED. For a given site, pre-operational activities (e.g. pile driving and seismic air gun surveying) are advised by cetacean sensitivity across months of the year that minimize impacts on migratory cetaceans, particularly those of highest conservation concern such as the North Atlantic right whale (Eubalaena Glacialis). For instance, within optimal sites for the New York Call Area the least impacting months are May and June. Other taxa are certainly affected by OWED and should be incorporated into this framework, but data on their distributions and/or sensitivities is currently less well known. Built with open-source software made publicly available, the authors hope this framework will be extended even more comprehensively into the future as our knowledge on species distributions and OWED sensitivities expands for streamlining environmental compliance.

In those countries where wind plays a major role in the energy mix (EU, China and USA) actions have been carried out to develop offshore wind energy, albeit to varying degrees. These actions range from studying offshore wind to the development of laws and planning related to the construction of wind farms. Europe currently leads the way in offshore wind energy (with 84% of global installations), having achieved technical and commercial maturity, including the first floating wind farm to generate electricity, together with an emerging zero-subsidy culture. The Chinese wind industry has seen rapid development since 2005, however, well established laws, the use of a one-stop-shop system in the licencing process, and the establishment of higher feed-in tariffs (FITs), could all boost the Chinese offshore wind industry further. The possible future role of the USA in the offshore wind industry is now in the hands of its decision makers. A more streamlined licencing process, together with a long-term vision enshrined within stable economic incentives, could help to boost the offshore wind industry in the USA.

Since the beginning of the 2000’, the French government ambition was to have an offshore wind production formed 40% of the renewable electricity in 2030. Three calls tenders of Offshore Wind Farms (OWFs) construction have been pronounced since 2011. However, no offshore wind farm (OWF) had been constructed at the end of 2017 due to long administrative procedures and numerous appeals in justice, at French and European levels. Nevertheless, several studies have been enterprised to identify the environmental conditions and ecosystem functioning in selected sites before OWF implantations. However, these studies are generally focused on the conservation of some species or groups of species, and there is no holistic study on the effects of the construction and operation of OWF on an ecosystem taken as a whole. In 2017, a complete and integrated view of the ecosystem of two future OWF sites of the eastern English Channel (Courseulles-sur-Mer and Dieppe-Le Tréport) was developed to model the marine ecosystems before OWF implementation and to simulate reef effects due to new spatial occupation of maritime territory. Results contribute to a better knowledge of the impacts of the OWFs on the functioning of marine ecosystems. They also allow to define recommendations for environmental managers and industry in terms of monitoring the effects of marine renewable energy (MRE), not only locally but also on other sites, at national and European levels.

This article explores stakeholder views on tidal energy in the state of Washington. Through compiling and analyzing three qualitative datasets, we take a triangulated approach to better understand stakeholders’ positive and negative views, concerns, and needs regarding tidal energy and if and how these are represented through print and online news sources. We analyzed comments submitted during the permitting process for the Admiralty Inlet Pilot Tidal Project, comments included as part of a tidal energy mail survey sent to Washington residents, and media articles about tidal energy. We found four types of concern themes within negative views towards tidal energy: environmental, social, economic, and technical. Shared concerns between organized stakeholder groups and resident stakeholders about the project and tidal energy in general included concerns related to the harm to marine life, the loss of native fishing rights, expensiveness of development, increased electricity costs, and the engineering challenge of developing tidal energy. Concerns unique to stakeholder groups for the project included threats from scaling up, issues related to public safety and security, damage to cables, inability to stop the turbine, harm to terrestrial flora, and sediment disruption and contamination. Positive views were commonly associated with the need to address environmental issues, technological innovation and leadership, desire to have a diverse energy portfolio, and economic benefits.

This work discusses and provides a critical expose of some of the newly emerging renewable energy technologies with special concentration on marine energy generation.

The work shows that there are several promising new developments in harvesting marine energy and it examines some of these technologies and discusses their advantages and some of the obstacles that are impeding the commercialization of these emerging technologies. This includes wave energy harvestingtidal energy harvesting, ocean thermal energy and the utilisation of salinity gradients for electricity generation.

The work emphasises the fact that these new emerging technologies are currently at the developing stages and has a long way to go before successful commercialization and wide adoption become the norm.

The work stresses the need for more research and developmental work to address several of the technical issues that need to be addressed including devices designs, their installation and maintenance, the infrastructure which includes the grid and power transmission as well as losses, their use in arrays, and their longevity.

This work underlines the lack of reliable studies on the long term impacts of these technologies on both the marine environment and nearby habitations and highlights the need for proper environmental and social impact assessments of these technologies.

The work concludes that combination of technical, policy and economic advances will enable marine energy technologies to play a large role in combination with currently adopted non-pollution renewable energy resources to provide the world population with their energy needs and contribute to affecting significant reduction in the use of non-renewable and other polluting fuels worldwide.
