While the world is abuzz about the potential of solar and wind power to drive the transition to a low-carbon economy, there’s a quieter giant lurking in the depths of our oceans, waiting to be tapped: tidal energy. That’s right, folks – tidal energy is not just a niche player in the renewable energy mix; it’s a game-changer that could provide a staggering 100% of the world’s electricity needs if harnessed properly.

But before we dive into the why, let’s address the elephant in the room: tidal energy is not a new kid on the block. It’s been studied, experimented with, and even deployed in various forms for decades. So, what’s holding it back from reaching its true potential? The answer lies in the sheer complexity of harnessing the power of the world’s oceans.
Tidal energy harnesses the predictable and cyclical movement of the tides to generate electricity. It’s like a giant, renewable battery that never runs out of charge. The benefits are numerous: it’s a baseload power source that can provide constant electricity, unlike solar and wind power, which are intermittent; it has a lower visual impact than traditional wind farms, which can be a major concern for communities; and it can be deployed in a variety of locations, including coastal areas and even in the open ocean.

The UK is one of the leaders in tidal energy, with the MeyGen tidal array off the coast of Scotland being one of the largest in the world. The array consists of 269 turbines that can generate up to 398 megawatts of electricity – enough to power over 180,000 homes. But despite the progress, tidal energy still accounts for a mere 0.02% of the world’s total electricity generation.
So, what’s holding tidal energy back? The main challenge is the high upfront cost of building and maintaining tidal energy infrastructure. The turbines and foundations required to harness tidal energy are massive, complex, and expensive. Additionally, the harsh marine environment can be unforgiving, with corrosion, ice, and extreme weather conditions all taking a toll on equipment.
However, innovation is on the horizon. New technologies, such as floating tidal turbines and innovative materials, are being developed to reduce costs and increase efficiency. The UK’s tidal energy industry is also benefiting from a coordinated effort between government, industry, and academia to drive innovation and deployment.
As the world continues to grapple with the challenges of climate change, energy security, and economic development, tidal energy is an unlikely hero waiting in the wings. It may not be sexy or trendy, but tidal energy has the potential to be a game-changer in the renewable energy mix. It’s time to give this unsung hero the recognition it deserves and start harnessing the power of our oceans to create a more sustainable future.
