In addition to the conventionalOTECplant facilities, SAOTEC power plants will not only affect local¶ environment, but may furthermore have global impacts on environmental parameters. For space-aided OTEC¶ plants, a solar reflector will heat the seasurface temperature up to 60°C. This will not only affect the maritime¶environment (i.e. flora and fauna) but might also contribute to global warming by heating the atmosphere.¶ The illumination of coastal SAOTEC plants by a solar reflector may cause a local, environmental disturbance¶ of the 24 hour day/night cycle of resident people, animals, plants and micro organisms (see 4.2.3). Countries¶ and governments planning to build a coastal SAOTEC power plant will have to consider and take precautions¶ to prevent threats to land-based activities, for both human health and well-being and the integrity of coastal¶ and marine ecosystems as well as the biodiversity.¶ There are three major legal documents which are applicable to the SAOTEC development and operational¶ phase:¶ The Law of the Sea Convention (1982)¶ The Washington Declaration on Protection of the Marine Environment from Land Based Activities (1995)¶ The Convention on Biological Diversity (1992)¶ The Law of the Sea Convention proclaims that States are responsible to ensure that activities under their¶ jurisdiction or control do not pollute another State’s environment27. Off-shore water SAOTEC plantswill use¶ Solar Reflectors to heat a delimited sea surface area in order to increase its temperature gradient to gain a¶ proper amount of energy. Even if a high reflector stabilization and precision pointing capability is required to¶ operate space-aided OTEC plants, a seawater temperature increase will not only strictly occur on the plant¶facility area, but will also raise the temperature of the surrounding water area. Habitats of sea organisms and¶ microorganisms will be affected and species might be extruded or displaced by other new species or alien¶ organisms. States are required to prevent these occurrences according to article 19628:¶ “States shall take all measures necessary to prevent, reduce and control pollution of the marine environment¶ resulting from the use of technologies under their jurisdiction or control, or the intentional or accidental¶introduction of species, alien or new, to a particular part of the marine environment, which may cause¶ significant and harmful changes there to”.¶ More specifically, environmental assessment and monitoring will be necessary to prevent harmful changes to¶ the marine environment29.”¶ The Washington Declaration on Protection of the Marine Environment from Land Based Activities (1995)¶ declares its commitment to protect and preserve the marine environment from the impacts of land-based¶ activities. But environment and biological biodiversity is not limited to plants, animals, microorganisms and¶ their ecosystems. The Convention on Biological Diversity 1992 recognizes that biological diversity is also¶ about people and their need for food security, medicine, fresh air and water, and a clean, healthy environment¶ in which to live. Besides producing energy to cover local energy demands, OTEC plants will also provide¶ desalinated water. OTEC plants might offer a safe and environmental friendly alternative to supply populated¶ areas with the produced water. Natural water deficiency can be compensated and biological diversity can be¶ maintained even if a local disturbance of maritime or land-based environment occurs.¶ The United Nations Framework Convention on Climate Change [United Nations 1992] recognizes that all¶ countries, especially developing countries, need access to the resources required to achieve sustainable social¶ and economic development. In order for the developing countries to progress towards that goal, their energy¶ consumption will grow. Taking into account the international needs for achieving greater energy efficiency¶ and for controlling greenhouse gas emissions in general, SAOTEC facilities can contribute to clean energy¶ production by using renewable energy source and avoiding the emission of greenhouse gases at the same time.
