Tidal energy is one of the five (5) Renewable Green Energy sources in the direction of which governments and institutions are looking in order to find solutions for their energy problems. Tidal energy is a clean and sustainable form of energy and there is evidence that it has been used by mankind for more than one thousand years ago. We will present some interesting facts about Tides and some uses of Tidal Energy which we believe are interesting for the general public. If you are looking about specific Tidal Energy facts you may find them in relevant documents.
Tidal Energy is a renewable energy source, RES, and in simple terms is the energy derived from the tides in the seas and oceans. The energy of the tides is captured by special tidal converters and it is converted into electricity or in some cases in other forms of energy.
The Tidal Energy together with the Wave Energy, are two types of RESs which are related to the oceans and thus they are grouped together under the Ocean Energy Resource Group. Ocean energy together with the Hydroelectric Energy, are grouped in the more general Group of RES called the Water Energy.
The cause of the Tides is the gravitational force of the moon and the sun. It should be noted that the gravitational force of the moon is greater than that of the sun and thus the tides from the moon forces are greater than those from the sun. There are instances where these two gravitational forces are unified, when the sun and the moon are aligned and this alignment makes the tides even stronger.
Tides are caused because the moon forces pull the waters of the oceans upward while the earth forces pull the waters down and the variation between the two forces is what causes the tides.
We have two types of tides, the spring and neap tides and these are caused at the different faces of the moon. The Spring tides are produced at full and new moon while the neap tides are produced at first and last quarter of the moon. Spring tides are higher than the neap tides.
The tides are higher at the beach and thus while they start low offshore, about 2 feet in height, they get higher as they approach the beach and they may get as high as 44 feet high. The highest tide is recorded in Nova Scotia at Fundy bay with the tide height reaching 44.6 feet.
Due to the earth’s rotation we get two tide peaks and consequently two tide troughs, each is separated from each other by 12 hours correspondingly, peek to peek or trough to trough.
One way to understand a new topic is to learn some interesting facts and used about it so that you will understand what all is about and the magnitude and impact this form of Renewable Green Energy Source has on our lives and the energy market in general. Here is a list of some of the interesting facts and uses of Tidal Energy:
From the articles and publications about Tidal Energy (Tidal Power) that we read we can safely conclude that the technology around this renewable green energy resource is rapidly developing and that there is a lot of interest and research going on in this area. The article about Tidal Energy facts for kids attempts to present some Tidal Energy facts for kids to understand the importance of Tidal Energy.
Tidal energy is expanding and the economics involved in building a tidal power plant are improving. With this in mind and given the fact that the various tidal technologies are improving we believe that soon we will more Tidal Power plants build around the world and this will increase the contribution of tidal energy to the total energy produced from renewable energy sources.
