What is renewable energy? : Limitations

From the renewable name you can easily understand what it means. Which can be implemented. In this case, by using something to produce energy, it is possible to produce energy again by that thing. That is, renewable energy is the source of energy that users use repeatedly. One of these is sunlight, biogas, water, wind, tidal waves, ground pressure, etc.

Below we describe the components of biogas, solar energy, tidal and renewable energy from wind:

Biogas (plant and animal)

The excrement of cows, goats, horses and buffaloes has been used as fuel since ancient times. These excrements of animals are a kind of source of energy. In different countries of the world, heat energy is generated by drying and burning dried dung. One of the elements or waste materials used in biogas is animal manure from cattle, pigs and chickens, grains and abandoned plants etc. In this case only animal manure or only plant ingredients or a mixture of both types can be used. The raw straw that is found in the feces of pigs or chickens is a good mixture of animal manure and plant material suitable for making biogas. However, you have to take small pieces while using them. In this case, it should be kept in mind that before starting, the dried vegetable ingredients should be cut into small pieces or peeled. And fresh plants should be allowed to rot outside for at least ten days.

The wind

Primitive people were afraid of the wind. As a result of the development of civilization and the development of science, people are using this air for various purposes. Primitive people made chakras with the help of four or five wings and made chakras with the help of wind. Using the friction of the wheel, people used to draw water from wells, irrigate, break barley or wheat, thresh sugarcane, cut paddy, cut straw etc. Later people used the wind to do hard work like sawing wood. In many parts of the world, people used to use a large circular device for this purpose. Which is now known as wind or windmill. But now its use has decreased. But again, its use has come to people's minds. Environmental pollution and the lack of natural energy, people are again thinking about the need for this windmill.

The tide of water

The use of tidal power in rivers or seas has been invented for a long time. But the conversion of tidal energy to electrical energy is not very long. At present, many countries around the world are trying to generate electricity by using tidal energy.

Solar energy

The energy that comes from the sun is called solar energy. We know that the sun is the source of all energy. All the energy in the earth has somehow been created using the radiant rays coming from the sun. Such fossil fuels, the carriers of modern civilization, are actually long-term stored solar energy

Work: To generate solar energy

Materials required: Fire glass / metal disc

Method: First take a fiery glass. Fiery glass usually has a convex lens. Focus on the sun with the help of the lens. You will see that if you focus properly, the fire will burn. Similarly, reflect the sun’s rays with a metal shiny disc. This makes solar stoves. We can easily cook with the help of this solar hair.

Solar energy is also used to keep homes warm in winter countries. Solar energy is used for drying grains, fish, and vegetables. It can be stored for a long time by making dried fish. Solar energy is used to generate steam in boilers, but it also turns turbines to generate electricity. Solar cells have been created using modern techniques. The characteristic of the solar cell is that when sunlight falls on it, it provides direct electricity. In addition, solar cells have a variety of uses.

The benefits of renewable energy are in the context of West Bengal

There are many benefits to renewable energy. As the world's population grows and the demand for energy increases, this energy has now become essential. Of these, biogas is used as a clean fuel. It helps to get high quality organic fertilizer. Is conducive to a pollution-free environment. Helps maintain a healthy and clean environment. Solar cells are used to supply electricity to artificial satellites. Various electronic devices such as pocket calculators, pocket radios, electronic clocks can be powered by solar energy. Basically the main advantage of renewable energy is that it is renewable, it will never run out. Its advantages are mentioned below.

Wind and solar energy are an inexhaustible source of energy. Because wind and sun always exist.

It is possible to produce a large amount of energy by using the water source. In this case, the bridge or barrage built to block the current improves the road communication.

Since the moon affects the tides of the water and it always exists, it is always possible to use the energy obtained from the tides of the water.

Renewable energy is generally environmentally friendly, as they do not emit large amounts of carbon dioxide into the air.

The need for renewable energy is as undeniable in different countrys as it is easy to obtain. It can be said that many countrys can be a milestone in the development of renewable energy. We have to take necessary steps for this now. 

Renewable energy: Limitations

There is a huge demand and interest for renewable energy at present. However, in some cases, the use of renewable energy is difficult. The following is discussed.

***The amount of electricity available from biogas is low and limited.

***The source of renewable energy from wind and current is limited. Because that's the point to make

It takes a convenient place to do it.

Renewable energy based on solar energy is available based on the presence of solar light, the production of which is for rain d
disruption occurs.

**Many times the use of tidal water as a source of renewable energy results in the course of a river

Changes. 

**In addition, the construction of bridges or barrages on the river also hindered the movement of ships.
