ABOUT OCEAN ENERGY
MARINE LIFE - This humpback whale is one example of a magnificent animal that is at the mercy of human activity. Humans are for the most part unaware of the harm their fast-lane lifestyles are causing. We aim to change that by doing all we can to promote ocean literacy.
Ocean Energy is energy or power (also sometimes referred to as ocean power) that is carried by carried by ocean waves, tides, and ocean winds. Harnessing this energy is one of the fastest growing enterprises the world over, most commonly with offshore wind farms.
The movement of water in the world’s oceans creates a vast store of kinetic energy, or energy in motion. This energy can be harnessed to generate electricity to power homes, transport and industries.
The oceans have a tremendous amount of energy and are close to many if not most concentrated populations. Ocean energy has the potential of providing a substantial amount of new renewable energy around the world. Energy from the ocean is also known as hydroelectricity.
There is the potential to develop 20,000–80,000 terawatt-hours (TWh) of electricity generated by changes in ocean temperatures, salt content, movements of tides, currents, waves and swells. Tidal energy potential is around 300TWh, while wave energy potential is thought to be between 8,000 - 80,000 TWh. Power from marine currents is thought to be in the region of 800TWh.
Offshore wind power or offshore wind energy is the use of wind farms constructed offshore, usually on the continental shelf, to harvest wind energy to generate electricity. Higher wind speeds are available offshore compared to on land, so offshore wind power’s contribution in terms of electricity supplied is higher, and NIMBY opposition to construction is usually much weaker. The cost of offshore wind power has historically been higher than that of onshore wind generation, but in 2016 had decreased to €54.5/MWh the 700 MW Borssele 3&4 due to government tender and size. Similarly, €49.90/MWh was achieved at the 600 MW Kriegers Flak.
FRANCE IN ACTION - On the 2nd of December 2015 in Saint Nazaire, the French Prime Minister, Manuel Valls, announced 2 winners for the construction of pilot tidal power farms. These projects represent a total investment of around €100 million, financed by the Investments for the Future programme (programme d'investissements d'avenir). The winners, selected from the submissions in response to the call for projects announced by the President of the Republic in 2013, were the Nepthyd project from Alstom and GDF Suez and the Normandie Hydro project from EDF and the DNCS group. The inauguration of Alstom's new offshore wind farm provides proof that energy transition can create skilled, long-term employment, with the expected creation of 300 direct jobs and 2,000 indirect jobs.
MAIN BLUE GROWTH AREAS
5. Ocean Regeneration - cleaning our oceans to preserve the resource and cleanse the toxic food chain
6. Aquaculture - now generates around 50% of world produce, mostly subject to wild fish feed
7. Ocean Energy - offshore wind and wave energy for clean power
8. Biotechnology - Identifying, harvesting and producing medicines
9. Coastal Tourism - To engage the public in ocean matters and reduce air travel
10. Green Ships - Cargo and cruise ships that are cleaner, preferably zero carbon
