The energy crisis is not a topic to be taken lightly. Due to our limited chemical resources of the planet, people are opting towards renewable energy that has infante resources. And Wave energy is on the top part of the list of renewable energy.
Whenever we think about renewable energy, the first thing that comes into our mind is solar energy and turbines. Capturing energy from Wind and the Sun are some of the most common energy sources. These sources do not emit harmful gases like CO2 in the air or change the course of climate in a negative direction.
But one of the biggest obstacles when it comes to solar and wind energy is their lack of constancy. On the best days, we get an only half day of sunlight. And winds are not constant as well. Even though there are some places where winds are fairly consistent, it is very difficult to store those wind energies. And to solve all of these problems, wave energy comes into play.
The fundamental building block of creating energy is a rotational force on the turbine. The machine does not look at what energy is being used to make the rotation. As long as the turbine or fan rotates, we will get energy on the other hand.
And the ocean waves can easily be used to provide this rotational energy to the turbine to produce clean energy.
If you are someone who stays near the ocean, you already know that waves crash on the shore every single day at every single moment. The up and down motion can easily be used to provide the rotational energy in the prime mover to generate electricity. And the greatest news is that there are limitations to this resource.
The only obstacle we will face is the initial investment needed for the hydroelectric power station.
There are two ways wave energy can be used to generate electricity. The first is the pressure of the waves deep under the ocean along the ocean floor. Or we can also utilize the waves on the ocean surface. Both of them have the same goal. And that is transforming the potential energy or the momentum of the wave into rotational energy in the prime mover. Which can later be converted into Electrical energy on the Alternator.
Wave energy is much denser than the solar power we can harness from sunlight through solar panels. To compare, a square meter of solar panel can harness somewhere around 0.2 to 0.4 KW of power. On the other hand, every meter of the coast can receive almost 30 KW of power.
Research has shown that it is possible to produce almost 1000 tera watt-hour of energy every year in the United States alone.
And this is why Wave energy is on the road to becoming the next big power source throughout the world.
