For decades, the renewable energy conversation has been dominated by solar and wind power. While these forms of energy have certainly made significant strides in recent years, there’s another, more ancient player in the game that’s been quietly harnessing the power of the ocean’s tides. Tidal energy, the renewable power source that’s been hiding in plain sight for centuries, is finally getting the attention it deserves.

But here’s the shocking truth: tidal energy has been powering coastal communities for thousands of years, long before the Industrial Revolution. The ancient Greeks and Romans used tidal mills to grind grain, and even the earliest forms of tidal barrages date back to the 19th century. So, what’s new about tidal energy, and why should we care?
The answer lies in modern technology. Advances in marine energy harvesting have made tidal energy a viable, scalable, and reliable source of renewable power. Unlike solar and wind power, which are subject to the whims of the weather, tidal energy is predictable and reliable. The ocean’s tides are driven by the gravitational pull of the moon and sun, creating a predictable and consistent flow of energy that can be harnessed using tidal barrages, tidal stream generators, or ocean thermal energy converters.

One of the most promising applications of tidal energy is in coastal communities, where it can provide a reliable source of power that’s less dependent on fossil fuels. Tidal energy can also help mitigate the impacts of climate change by reducing greenhouse gas emissions and providing a source of energy that’s not subject to the same price volatility as fossil fuels.
But tidal energy isn’t just a niche player in the renewable energy market. It has the potential to become a major player, with some estimates suggesting that it could provide up to 10% of the world’s electricity by 2050. And with the global tidal energy market expected to grow from $400 million in 2020 to over $10 billion by 2027, it’s clear that this industry is on the cusp of a major breakthrough.
Of course, there are still challenges to overcome. The high upfront costs of tidal energy infrastructure are a major barrier to adoption, and the environmental impacts of tidal energy projects must be carefully managed to minimize harm to marine ecosystems. But as technology continues to improve and economies of scale are achieved, these challenges will become less significant.
As we look to the future of renewable energy, it’s time to give tidal energy the recognition it deserves. This ancient, unsung hero of renewable power is ready to take its place alongside solar and wind as a major player in the global energy mix. So, let’s harness the power of the ocean’s tides and unlock the full potential of this incredible source of renewable energy.
