Wave power is among the cleanest alternative sources of energy and is both safe and renewable.
Catching the power of waves within the ocean is an extremely old concept, but only recently has it been achievable with any amount of success.
Today, we can now harness the power of waves to generate electricity.
Wave energy is the method of using the ocean waves' power.
This power essentially originates from the gusts of wind that create the swells in the ocean; the wind flow originates from different various heat temperature ranges around the globe and the Earth's unequal surface area.
The waves may well seem like it moves in a single motion and path; however the water molecules actually move within an ellipse.
This elliptical motion of water is how we obtain the wave energy.
Harnessing this power is now possible through the Pelamis wave energy converter which is found in Scotland.
In fact, it is the very first system that has been successful in generating power from waves and is the system most commonly used.
This revolutionary product functions through the numerous steel cylinders which are linked by hinges.
Once the wave moves, the various cylinders move too and the hinges are attached to hydraulic rams that push oil through hydraulic engines.
These snake-like capsules drift across the surface on the water using the waves.
This motion is resisted internally by hydraulic pumps that transfer a hydraulic liquid via a hydraulic motor.
This motor is attached to generators and waves will thus drive the power generator to create electrical power.
From that point, power packs that will retain the power produced which will be delivered to the coast line by using just one cable. Finally, the electricity will be gathered in a wave energy farm for distribution through power lines.
There are additional ways of using wave energy. There are several techniques like utilizing buoys that drift on the surface of the water.
These buoys transform the wave energy into mechanical power which then transforms into electrical power.
Waves are produced by blowing wind across the top of water. Consequently, higher wind gusts signify larger waves.
On the other hand, tides are made from the gravitational forces of the moon and the sun which causes the ocean to bulge.
This bulging is responsible for high and low tides. In terms of power and strength, tides remain pretty consistent compared to waves.
Also, tidal power costs slightly less to build and maintain.
The benefits of wave energy are substantial.
Wave energy is definitely an abundant and environmentally friendly resource and although not all countries have a shoreline, the combined potential output of wave power would satisfy all of the electrical power requirements around the globe.
Even though equipment represents a considerable financial commitment, the fuel is free of charge and never limited by geopolitical borders.
Finally, the damage to the natural environment is considered to be minimal and thus it will help stop climate change.
