Canada is known as the second-largest producer of hydroelectricity in the world coming second to China. As a global leader, Canada is actively in urging other countries to build-up their own production and distribution of hydroelectricity, known as a renewable source.
For anyone interested in learning more about hydroelectricity, here are the primary details you all need to know.
Hydroelectricity is produced by gravity and water cycles. The hydrologic cycle refers to the process of water evaporating from the oceans to form clouds and then fall from the sky as either rain or snow. Water from rain and snow then gathers into rivers and streams and then find their way back to the sea.
In this cycle, humanity has found a way to generate a form of energy through nature’s own engines.
The Turbine and Generator
To generate electricity from moving water’s kinetic energy, a propeller-like device called a turbine is needed. Movement of water from rivers and streams that have sufficient speed will spin the turbine around. Through the turbines that water then rotates a generator which well, generates electricity.
The concept is simple to understand but there are certain things to consider before doing so. You need to think of the source of water and if it is able to keep on pushing water currents towards the generator.
To generate one kilowatt of electricity, one gallon of water per second falling from 100 feet is needed.
The Pros and Cons
Hydroelectricity is without a doubt clean and renewable. It does not emit greenhouse gas emissions nor air pollution. It is also an affordable alternative when it comes to electricity. However, there are also certain downsides with hydroelectricity. The most common one is water quality degradation because of blocking rivers using dams. In doing so, riparian and aquatic habitats can be damaged.
That is why it is important to assess everything, especially the potential environmental and social consequences. But if done right and responsibly, there is a way to avoid all the negative impacts and still generate a great amount of hydroelectricity.
Clean and renewable energy sources are more important than ever.
