The renewable energy produced by the natural rise and fall of ocean waters.
Show Hint
Solution and Explanation
Tidal energy is a form of renewable energy that is generated by the natural rise and fall of ocean waters. This movement of water is caused by the gravitational pull of the moon and the sun on the Earth's oceans, which creates tides.
Step 2: How Tidal Energy Works.
Tidal energy is harnessed using tidal turbines, which are similar to underwater wind turbines. The turbines capture the energy produced by the moving water during the high and low tide cycles. The kinetic energy of the moving water is converted into electrical energy.
Step 3: Tidal Power Plants.
There are two main types of tidal power plants: tidal stream systems and tidal range systems. Tidal stream systems use the flow of water, while tidal range systems use the difference in water levels between high and low tides to generate power.
Step 4: Environmental Impact and Benefits.
Tidal energy is considered a clean and renewable source of energy because it does not produce greenhouse gases or pollution. Additionally, it is highly predictable, making it a reliable source of energy. However, its use is limited to coastal areas, and the construction of tidal power plants can affect marine ecosystems.

- Object-Oriented Programming
- Write a program to accept a two-dimensional integer array of order \( 4 \times 5 \) as input from the user. Check if it is a Sparse Matrix or not. A matrix is considered to be a sparse, if the total number of zero elements is greater than the total number of non-zero elements. Print appropriate messages.
