Climate change and growth of the world population is finally making us create a common wake-up call about to be taken serious: the use of fossil fuels must be reduced. As a result of this, development of renewable energy is gaining ground. For a long time, renewable energy has been developed land-based, however there is now a growing trend for renewable energy to be developed in the sea. Because of the benefits of offshore renewable resources, sea is becoming a playing field for new developments. For example, as for wind energy, marine winds are more abundant, stronger, and blow more consistently than land winds.
