Petroleum and natural gas beneath the ocean floor are also sometimes considered a form of ocean energy.

They found developments in other technologies (especially materials sciences) were improving the viability of mineral extraction processes that employ ocean energy.

Accordingly, ocean current energy could become a vital part of the world's energy future.

Let's start with systems designed to capture the mechanical forms of ocean energy.

In the area of R&D, is developing the Cenit Ocean Líder project, the most extensive world research into ocean energy.

Other renewable energy technologies are still under development, and include cellulosic ethanol, hot-dry-rock geothermal power, and ocean energy.

However, the temperature differential is small and this impacts the economic feasibility of ocean thermal energy for electricity generation.

Erris has considerable potential for ocean energy in terms of its location next to the Atlantic Ocean and constant winds from the sea.

In the electricity sector, ocean energy will be the next big development and we have to put money into solar thermal electricity development.

In doing so, the CycWEC extracts the ocean energy to rotate a shaft which can drive a generator, converting the wave power into electrical power.
