Tidal stream causes the blades of the turbine to rotate, much like a wind But, water is denser than air, which makes its flow more powerful. These turbines are placed underwater and are fixed to the seabed for their support. For this, tidal stream turbines are used to convert the flow of the stream into the electricity. Tidal streams (flowing bodies of water) that are created by the tides can be used to produce electricity. Tidal Stream Tidal stream electricity generation Each method has its own advantages, depending on the geographical locations. There are three main methods for generating electricity from the tides. Tidal mill Methods of Generating Electricity Only few power generating stations are producing electricity from them. But, generating electricity from tides is a new concept. For this, they had built tide mills to generate mechanical power for grinding and other purposes.
Romans had known how to generate power from the tides. The concept of using the tidal energy for generating power is not new. Tidal energy is considered as a type of renewable energy source because we do not consume the tides in generating power from them. Unlike wind power, in which winds are unpredictable. The main advantage of generating power from the tides is that they are reliable and highly predictable. This energy is harnessed with the use of special devices, such as tidal turbines to generate electricity or mechanical power. Tides are full of energy due to their motion.
