alternative energy

we all know that energy is a basic requirement of every human being. no one who does not require energy. but with increasing number of people in the world, the more increase also the world's energy needs. but the number of energy sources in the world is inversely proportional to the level of very high energy requirements. energy sources more and more depleted because most of the world's energy resources are resources that can not be updated. of which is fossil fuels.

therefore we need to look for alternative energy as energy reserves in the future. but thatalternative energy must be environmentally sound and their availability for long enough.alternative energy are among the ocean waves.

You who live by the beach of course will always be watching how every day the surf is always "banging" the beach. Well wave power or wave is then used by humans to putsome tools such as "rafts" which continued in such a way that every time "through" the waves will move the hydraulic pump which then produce energy. This method is known as the method Cockerell. There are also other methods such as tube Masuda, Kayser,and buoys Salter, all of which is to "capture" wave power for utilized energy. Some countries that have used this type of energy sources are France, Russia, and Australia.
