Did you know that the global ocean currents have enough energy to power the entire world for over 100 years? Yes, you read that right! According to a study published in the journal Energy & Environmental Science, the kinetic energy generated by ocean currents could provide a staggering 2.7 billion terawatt-hours of electricity per year. That’s equivalent to the total global electricity generation in 2019, which was approximately 26,000 terawatt-hours.

As we continue to grapple with the challenges of climate change, energy security, and sustainable development, a new player is emerging on the global energy scene: ocean current energy. This innovative technology harnesses the power of ocean currents, tides, and waves to generate clean, renewable energy. And the potential is enormous.
Ocean current energy is still in its infancy, but it’s gaining momentum fast. In fact, several countries, including the UK, Australia, and South Korea, have already started investing in ocean current energy projects. The technology involves the use of floating turbines, known as ocean current turbines (OCTs), which are deployed in strategic locations to capture the energy generated by ocean currents.

The benefits of ocean current energy are numerous. For one, it’s a predictable and reliable source of electricity, unlike solar and wind power, which can be intermittent. Additionally, ocean current energy has a significantly lower visual impact compared to traditional offshore wind farms, making it an attractive option for coastal communities. Plus, the ocean’s kinetic energy is a virtually limitless resource, providing a long-term solution to our energy needs.
However, there are also challenges to be addressed. The technology is still in its early stages, and the cost of deploying OCTs is relatively high. Moreover, the complex marine environment poses significant logistical and technical challenges. But, as with any emerging technology, the costs are expected to decrease as the industry scales up and innovates.
Some of the most promising ocean current energy projects are being developed in the Gulf Stream, a powerful ocean current that runs along the eastern coast of the United States. The Gulf Stream has a significant impact on the climate, and harnessing its energy could provide a major boost to the US renewable energy sector. Other hotspots for ocean current energy development include the North Sea, the Mediterranean, and the Indian Ocean.
As the world continues to transition towards a low-carbon economy, ocean current energy is poised to play a significant role. With its vast potential, low visual impact, and predictable output, it’s an attractive option for countries looking to diversify their energy mix. As the industry grows, we can expect to see significant advances in technology, reductions in costs, and increased investment. The tidal wave of the future is here, and it’s powered by the ocean.
