All forms of marine energies (like tidal and wave power, marine current power, OTEC and osmotic power) are still in its infancy and need further development in order to gain competitivity and efficiency. Their potential in terms of amount of…

Top 7 examples of renewable energy sources

2462229068_7a65fd5192_z

Renewable energy sources are those obtained from inexhaustible natural resources on a human scale. This can be caused either because the sources are limitless (the Sun, wind, etc.) or because the natural resource has the capacity to regenerate itself naturally…

4 most relevant tidal power generation methods

0

Tidal power is a form of marine power. The power of the rise and fall of the sea level can be harnessed to generate electricity. There are only a few commercial tidal power plants operating in the world. The oldest one is located in La…

Where is tidal energy used?

Tidal energy is a sustainable source of energy that has been used for many years worldwide. The principle of tidal energy is based on capturing the movement produced in the water by the tides. This is achieved by using turbines which…

Case study of Tidal Power Plant: The SeaGen project

12771318925_301fd3b585

The SeaGen project is a tidal energy project located in Strangford Lough, Northern Ireland and developed jointly by the UK Government and private investors. The unique design and location of the SeaGen project allows capture of the maximum amount of tidal energy…

Tidal Power in Scotland, an opportunity to harness sustainable energy

0

Edinburgh and Oxford University professors have estimated that about 25% of Europe’s tidal energy resources are in Scotland’s coastal areas. These areas have the potential to generate vast quantities of tidal, wind and wave power. It has also been said that tidal…

The early history of tidal energy projects

7831696854_93e8ceb489_c

The idea of using the energy of the tides is not new. Tidal mills were built in France, Spain and Portugal as early as the twelfth century. A mill powered partially by tidal energy was built at Port-Royal, Nova Scotia,…

What is marine current power?

0

Marine current power is a form of marine energy that can be obtained from very different origins such as wind, tides, difference in density, salinity gradients (osmotic power) or temperature (OTEC). Independently of the origin of the currents, they all…

What is the marine power?

The marine power or marine energy is the exploitation, use or application of the energy carried by waters (oceans, seas, rivers, tides, marine currents, salinity, etc.). Sometimes is also named ocean energy or ocean power. This energy is transformed into…
