Abstract

The world is constantly seeking new sources of energy to replace the use of coal and fossil fuels to generate electricity. And a strong source of energy from the ocean is one of the hopes of scientists around the world. Ocean energy is an endless renewable energy source for making electricity used for the world. Marine technology was once considered too expensive to be a viable source of alternative clean energy, especially compared to already developed products such as wind and solar. However, with the increased price of oil and the issues of global warming and national security, U.S. coastal sites are looking to add ocean energy to their renewable energy portfolios. This paper gives an overview of ocean energy technologies, focusing on two different types: wave, tidal. It outlines the operating principles, the status, and the efficiency and cost of generating energy associated with each technology.

Highlights

In modern life, the quality of human life depends very much on energy resources, so the exploitation and use of energy are concerned by countries
Traditional sources of energy such as fossil fuels, hydropower and nuclear power have met most of the needs of nations, but the use of these energy sources has certain limitations
We know that crude oil, natural gas and coal are all fossil fuels and that “Fossil fuel” is the general expression used to describe any type of “hydrocarbon” material that can be burnt or used as a fuel releasing its energy as heat [1]

Summary

INTRODUCTION

The quality of human life depends very much on energy resources, so the exploitation and use of energy are concerned by countries. Fossil energy is not renewable and at the current rate of use, scientists predict that in about 70 years the fuel will be depleted. We know that crude oil, natural gas and coal are all fossil fuels and that “Fossil fuel” is the general expression used to describe any type of “hydrocarbon” material that can be burnt or used as a fuel releasing its energy as heat [1] They are called hydrocarbons because their chemical structure is based on a combination of hydrogen and carbon atoms. The basic principle of using renewable energy is to extract part of the energy from continuous processes in the environment and put it into technical uses These processes are often promoted especially from the Sun. Renewable energy replaces traditional fuel sources in four areas: power generation, hot water heating, engine fuel, and rural independent power systems [2],[31]. The tide is always active every year, this is a renewable energy source that brings the highest efficiency and especially with the lowest cost [39]
