Abstract – Discovering, finding, and evolving alternate
Quartz is made up of a hexagonal structure of Silicon and Oxygen atom where one silicon bonds with two Oxygen.
sources of renewable energy is the need of the hour. We never know, which alternate we discover, turns out to become much more energy efficient than the already existing ones. In this paper, I introduce a yet another revolutionary way of harnessing energy through the concept of Piezoelectricity. Piezoelectricity is producing electricity by applying pressure on a particular stone[1]. This paper delves into the application of this concept in harnessing electricity from tidal pressure with the help of results from the experiments conducted and the calculations made. Along with this, it also provides several other applications of this concept while explaining at the end, how this is going to be cost-efficient. Key Words: Renewable Energy, Piezoelectricity, Tidal Pressure.
Tidal
Since Oxygen is more electronegative then silicon, the silicon-oxygen bond is polar. In the hexagonal structure, the net electric charge gets developed in the center of the hexagonal structure. However, when a mechanical stress is applied, there is a change in this hexagonal structure, and the net electric charge shifts its position. This change in the position of electric charge produces a voltage[3].
Energy,
The diagram given below shows the structure of Quartz.
1.INTRODUCTION A piezoelectric crystal produces a voltage generating AC current whenever a mechanical stress is applied to it. Already creation of piezoelectric footpaths and footsteps is put in place where electricity is produced due to the mechanical stress applied by the action of placing one’s foot in the special footpaths or footsteps made of piezoelectric material.

But this is not a very efficient way of producing loads of electricity.
2. The concept of PEG( in oceans)
I casually came up with a thought of harnessing tidal energy with this concept, the day when I experienced the strong force of waves at the seashore.
PEG is a plate made of piezoelectric material, installed vertically upright on the sea floors, near the seashore.
I have performed few experiments, trying to calculate and estimate, the extent of energy generation with this method.
It is placed in a such a way that the piezoelectric part of the plate is just on the surface of ocean so that impact with the waves could be made easily.
In this process, I also came up with several other applications of Piezoelectricity which could also be significant in energy generation.
Whenever the oceanic waves will rhythmically, voltage will be produced.
Therefore, we may say that the infrastructure for the PEGs is already ready for us.
Piezoelectric crystals are generally made of Quartz, and the mechanism involved is actually the movement of electrons due to application of stress[2].
Impact Factor value: 8.226

Also, quartz, of which the piezoelectric disc is made of, also yields silicon which is used in making the Photovoltaic cells of solar panels.

This is therefore a cleaner and greener source of Energy.
One such is a suggestion of a new design of water turbines.
