To coordinate the contradiction between economic development and climate change, countries all over the world are vigorously developing renewable energy. Among all renewable energy sources, onshore solar energy, hydro energy and wind energy are limited by the land and environment. The marine is rich in various energies, including marine wind energy, wave energy, tidal energy and marine biomass energy, marine oil and mineral resources. In the development of marine energy, various offshore structures are generally adopted and constructed including offshore wind turbines, wave energy power generation devices, offshore oil and gas exploitation platforms, etc. The safety and reliability of these structures are vital for marine (renewable) energy development. In the meanwhile, marine energy development involves multiple disciplines, which are related to marine biology, chemistry, ecology and the environment. The interdisciplinary studies on these topics are also of significance in marine energy development. In addition, human activities (e.g. marine policy, marine transportation planning, environmental management, economic assessment, and culture) influence the development process of marine energy, which also needs to be investigated.

In the last decade, the concept of a Blue Economy has ignited a deep theoretical debate. Ranging from the integration of the triple bottom line of sustainability to the optimization of profit from ocean exploitation, the meaning of the term blue economy differs considerably between epistemic communities and even more so among national and regional policies. There is a general sense of the opportunity to realise enhanced social and economic benefits from the sustainable utilisation of their ocean and coastal resources under the umbrella framework of blue economy. Blue economy is gaining traction already as a significant component of national policies, even in spite of a clear conceptualization of the term. Many countries are now preparing national policies towards realising their blue economy ambitions, utilizing the concept as they see fit. Likewise, multilateral and regional organisations are developing guidelines, and providing investment in new research, technologies, and financing tools that promote blue economy. Critical challenges abound, in particular in less privileged countries. These include the gap in research capabilities, governments prioritizing social wellbeing and economic profit in contrast to environmental protection, the identification of new and emerging areas of ocean economic activity that are both socially and ecologically sustainable and holds viable business models that can attract private investment.

Developments in Renewable Energies Offshore contains the papers presented at the 4th International Conference on Renewable Energies Offshore (RENEW 2020, Lisbon, Portugal, 12 - 15 October 2020). The book covers a wide range of topics, including: resource assessment; wind energy; wave energy; tidal energy; ocean energy devices; multiuse platforms; PTO design; grid connection; economic assessment; materials and structural design; installation planning and maintenance planning. The book will be invaluable to professionals and academics involved or interested in Offshore Engineering, and Renewable and Wind Energy.

Encyclopedia of Renewable Energy, Sustainability and the Environment, Four Volume Set comprehensively covers all renewable energy resources, including wind, solar, hydro, biomass, geothermal energy, and nuclear power, to name a few. In addition to covering the breadth of renewable energy resources at a fundamental level, this encyclopedia delves into the utilization and ideal applications of each resource and assesses them from environmental, economic, and policy standpoints. This book will serve as an ideal introduction to any renewable energy source for students, while also allowing them to learn about a topic in more depth and explore related topics, all in a single resource.Instructors, researchers, and industry professionals will also benefit from this comprehensive reference. - Covers all renewable energy technologies in one comprehensive resource - Details renewable energies' processes, from production to utilization in a single encyclopedia - Organizes topics into concise, consistently formatted chapters, perfect for readers who are new to the field - Assesses economic challenges faced to implement each type of renewable energy - Addresses the challenges of replacing fossil fuels with renewables and covers the environmental impacts of each renewable energy

Marine/freshwater biological resources are of great economic, social and ecological value. Aquatic ecosystems, mainly formed by aquatic biological resources, play an important role in maintaining material circulation, energy flow, and environmental purification. Efficient, safe, sustainable utilization and high-value development of marine/freshwater biological resources, thereby promoting grain security, food security, and environmental security, has been a long term research focus. It is one of the most practical and innovative fields in global scientific and technological innovation and an effective way to solve the major problems restricting human resources shortage.
