As the world continues to grapple with the challenges of climate change, renewable energy has become a hot topic of discussion. Among the various forms of sustainable energy, tidal energy has long been touted as a game-changer. But is it really? The answer, it turns out, is a resounding “not quite yet.”

For decades, tidal energy has been hailed as a potential powerhouse of renewable energy, with the ability to generate electricity from the predictable and reliable movement of ocean tides. Proponents argue that it’s a virtually limitless source of energy, with the potential to power entire cities and communities. But the reality is far more complicated.
One of the main issues with tidal energy is the cost. Currently, the cost of building and maintaining tidal energy farms is prohibitively expensive, making it difficult to compete with traditional fossil fuels. In fact, the cost of tidal energy is often cited as being anywhere from 2-5 times higher than other forms of renewable energy, such as wind or solar power.

Another issue is the environmental impact. While tidal energy is often touted as a “green” source of energy, the truth is that it can have significant environmental consequences. For example, tidal energy farms can disrupt marine habitats and interfere with the migration patterns of marine animals. Additionally, the cables and other infrastructure required to support tidal energy farms can also have negative impacts on the ocean floor.
But perhaps the biggest issue with tidal energy is the scale. Despite its promise, tidal energy is still a relatively small player in the global energy market. In 2020, for example, tidal energy accounted for just 0.02% of global electricity generation. Compare that to wind energy, which accounted for over 6% of global electricity generation in the same year. It’s clear that tidal energy still has a long way to go before it can make a significant impact on the global energy market.
So, what’s the future of tidal energy? While it’s unlikely to become a dominant player in the global energy market anytime soon, it’s still a promising technology that could play a role in the transition to a more sustainable energy future. In fact, many experts believe that tidal energy will become more viable as technology continues to improve and costs come down.
For example, researchers are currently exploring new technologies such as submerged tidal stream generators, which use underwater turbines to harness the power of ocean currents. These devices have the potential to be more efficient and cost-effective than traditional tidal energy farms, and could help to make tidal energy more competitive with other forms of renewable energy.
In conclusion, while tidal energy may not be the game-changer we thought it was, it’s still a promising technology that deserves attention and investment. As we continue to grapple with the challenges of climate change, it’s clear that we need all the help we can get – and tidal energy could be an important part of the solution. But for now, let’s temper our expectations and focus on making tidal energy a more viable and sustainable option for the future.
