For decades, solar panels and wind turbines have been touted as the future of renewable energy. And while they’ve certainly made significant strides in recent years, there’s a quiet giant in the energy sector that’s been generating power for over a century: hydroelectric power.

That’s right – hydroelectric power, the oldest and largest source of renewable energy, often gets overlooked in favor of newer, trendier technologies. But the truth is, hydroelectric power is not only still a major player, but it’s also a highly efficient and reliable source of energy that deserves more attention.
Let’s start with the basics. Hydroelectric power plants harness the energy of moving water to generate electricity. It’s a simple yet effective principle that’s been around since the late 19th century. And while the technology has evolved over the years, the fundamental concept remains the same: water flows from a higher elevation to a lower elevation, driving a turbine that produces electricity.

So, why is hydroelectric power so often overlooked? One reason is that it’s often associated with large dams, which can have negative environmental impacts. However, many modern hydroelectric power plants are designed with sustainability in mind, using smaller, more flexible designs that minimize disruption to ecosystems.
Another reason hydroelectric power gets short shrift is that it’s often seen as a regional, rather than global, solution. But in reality, hydroelectric power is used in over 150 countries around the world, from the mighty Three Gorges Dam in China to the smaller, community-based projects in rural Africa.
So, what are the benefits of hydroelectric power? For starters, it’s a highly reliable source of energy. Unlike solar or wind power, which can be intermittent, hydroelectric power is available 24/7, 365 days a year. It’s also incredibly efficient, with some plants achieving power generation rates of over 90%.
And then there’s the environmental impact. When done right, hydroelectric power can be a net positive for the environment. By harnessing the energy of moving water, hydroelectric power plants can help to stabilize water flows, prevent flooding, and even support aquatic ecosystems.
Of course, there are challenges to implementing hydroelectric power. Building a new dam can be a complex and expensive process, requiring significant investment and infrastructure. But for many countries, the benefits far outweigh the costs.
In fact, hydroelectric power is already an integral part of many countries’ energy mix. In Norway, for example, hydroelectric power accounts for over 95% of the country’s electricity generation. In Brazil, it’s over 60%. And in the United States, hydroelectric power plants generate enough electricity to power over 22 million homes.
So, what’s the future of hydroelectric power? With advancements in technology, we can expect to see even more efficient and sustainable hydroelectric power plants in the years to come. And with the global shift towards renewable energy, hydroelectric power is poised to play an even bigger role in the energy mix.
It’s time to give hydroelectric power the recognition it deserves. It’s not just a relic of the past, but a vital component of our renewable energy future.
