Ocean and Tidal Energy
I. Tidal Energy:
The building of a barrage across an estuary to prevent the incoming and outgoing tides is required for tidal power generation. As with hydroelectric dams, the head of water is utilized to drive turbines that create energy from the raised water in the basin.
Barrages can be built to generate power on the ebb, flood, or both sides of the river. The tidal range can range from 4.5 to 12.4 meters depending on the location. For cost-effective operation and adequate head of water for the turbines, a tidal range of at least 7 m is necessary.
II. Ocean Power:
Oceans encompass more than 70% of the Earth’s surface, making them the biggest solar collectors on the planet. Ocean energy is derived from water waves, tides, and thermal energy (heat) stored in the ocean. The sun warms the topwater far more than the deep ocean water, storing thermal energy in the process.
Non Conventional Sources of Energy In India’s Perspective
Renewable energy sources, often known as non-conventional energy, are sources that are renewed by natural processes on a continual basis. Solar energy, wind energy, bio-energy (bio-fuels cultivated sustainably), hydro-power, and other sustainable energy sources are some examples.

A renewable energy system transforms energy from the sun, wind, falling water, sea waves, geothermal heat, or biomass into heat or electricity that humans can utilize. The majority of renewable energy originates from the sun and wind, either directly or indirectly, and can never be depleted, which is why it is termed renewable.
However, traditional energy sources such as coal, oil, and natural gas provide the majority of the world’s energy. Non-renewable energy sources are the word used to describe these fuels. Despite the fact that the accessible amount of these fuels is enormous, they are finite and will, in theory, ‘run out’ at some point in the future.
