Abstract
Much attention to the risks of global climate change increases the interest in research and development of renewable energy technologies. The ocean provides a vast source of potential resources, and as renewable energy technologies develop, investment in ocean energy is growing. Research in the conversion of ocean thermal energy, wave energy, tidal energy, offshore wind energy into useful technologies and commercial expansion. The potential of these resources helps to reduce the risk of global climate change, but the ocean environment must be protected against these developed technologies. If the desired projects have proper measurement and placement and environmental guidelines are followed properly, the renewable energy resources of the ocean may be exploited without harming the marine environment. This article examines this technology and its status in the world
