Introduction
Wave and tidal energy are forms of renewable energy derived from the ocean’s natural movements. These sources have gained increasing attention due to their potential as clean and sustainable alternatives to traditional fossil fuels. In this article, we will explore the historical background, key concepts, advantages and disadvantages, economic implications, technological advancements, case studies, current trends, challenges, future outlook, and the importance of wave and tidal energy in shaping our renewable energy landscape.
Historical Background
The history of wave and tidal energy can be traced back to ancient civilizations that used the power of the ocean for various purposes. However, it was not until the 20th century that serious attempts were made to harness this energy on a larger scale. The development of wave energy converters and tidal turbines in the 1970s marked significant milestones in the field, leading to further research and technological advancements.
Key Concepts and Definitions
Wave energy refers to the capture and conversion of energy from the ocean’s waves, while tidal energy involves harnessing the power of tidal currents. Although both sources come from the ocean, they differ in terms of their mechanisms and available resources. Understanding key concepts such as power density, wave height, tidal range, and energy conversion systems is essential to grasp the complexities of wave and tidal energy.
