Energy is essential for the evolution of life on Earth. However, a significant portion of the energy we use today comes from non-renewable sources. This shows that once they are exhausted, they cannot be satisfied. The most important source of non-renewable energy is fossil fuels which have taken millions of years to produce Veteran Energy Rates . So it is important to use them in a good way. This forces us to look elsewhere. We know that energy exists in different forms and forms and cannot be created or destroyed. But it can be transferred from one form to another form. Forces of nature – sun, wind, waves, tides, etc. can be converted into a usable form. One of these renewable energy sources is hydropower.
What are tides?
The gravity of the sun and the moon combined with the rotation of the earth causes the sea to rise and fall again, in one place, it usually happens twice a day. The rise of the sea level is called high tide, while the fall is called low tide. When the gravitational forces of the Earth and the Moon are in a straight line, the effect of these two fields is stronger and causes millions of gallons of water to flow onto the shore, causing a tidal wave. Similarly, when the gravitational pulls of the moon and the earth are equal, the effect of these fields is reduced, causing water to move away from the shore, making the water is low.
When the Moon is perfectly aligned with the Earth and the Sun, the gravitational pull of the Sun and the Moon on the Earth becomes stronger, the high tides rise significantly and the low tides often recede during their cycles. any. This situation occurs during the full moon or new moon. These tides are called spring tides. Similarly, another rainy condition occurs when the gravitation of the moon and the sun oppose each other, canceling their influence. This results in a smaller difference between the low and high tides due to less drag on the river water, thus causing a low tide. These low-lying rivers are called sunny rivers. High tide occurs during the quarter.
What is tidal energy?
Tides are common. They can be predicted months and years in advance. This is why the energy of this mass movement of water can be harnessed and converted into usable energy.
Tidal Power Generator
The energy obtained from the rise and fall of the tides is called tidal energy. A dam or barge is built to enter the sea through a narrow strait. Water flows into the dam when the sea level rises. This moves the blades of the turbines which connect to the opening of the dam. This results in the production of electricity.
Advantages of tidal power
- Place of residence
- A very powerful source
- High energy density
- Low operating and maintenance costs
- An inexhaustible source of energy
Disadvantages of tidal power are:
- The cost of building a port is high
- Adverse effects on marine life
- A lot of space
Although it is not widely used, tidal energy can generate electricity in the future. Among other sources of renewable energy, tidal power has suffered from high costs and limited availability of construction sites. However, due to recent technological developments that show that economic and environmental costs can be brought down to a competitive level, it seems that the future is bright for tidal energy production.
