INTRODUCTION
Energy means power is required to get work from every person or thing. And the source of this energy is energy. Energy sources have a very serious effect on manpower. Constant efforts are being made to sustain energy consumption through new technologies. The very idea of ​​depleting energy resources can lead to the destruction of the world. That is why the time has come to make alternative use of unconventional researches like solar, hydro, wind power. Efforts are being made to innovate in energy production by developing more efficient machinery. The first ray of hope was received in 2006. A company named Sonam made 12.5% ​​efficient solar cells. In the same month, Sajo Company launched 12.5% ​​efficient solar cells in the market. A man named Yoshirosaji has discovered a magnetic ship in Japan. Similarly, a magnet train is an excellent way to get out of an energy crisis. Each flash of lightning has a minimum of 1 million volts and a maximum of 1 billion volts. If this energy can be stored, then there can be a revolution in the field of energy.
Acceptance of changes in half a century of research
Ancient energy systems are at a turning point, as shown in European cooperative research 40 years ago. A total of seven global partners in the program are saying that now is the time to find energy in solar energy. In which the security of the citizens and the two main issues of the society are to be taken into special consideration. Efforts to ensure that energy does not adversely affect human life began 30 years ago. Apart from that, Japan, Russia, India were also carrying out this research.

At the commencement of electrification of five villages in the Sagardwip Islands of India-South Bengal (WBRDA), the committee said that the combination of both light and energy would give impetus to the development of the world but this adventure must be seen to not lead to the destruction of human life. The Rural Electrification Corporation (RFC) instruments point out the need for the development of clean technologies, leaving behind polluted fuels, in the same way that the world would need programs to make the world less carbon-intensive. The impact on society in terms of a better illumination level with respect to kerosene lanterns and exposure to entertainment through electronic media is of great significance. It can also benefit the consumer and the manufacturer financially. Speaking of farmers, electricity can bring a tremendous improvement in their standard of living. That's what researchers believe. Similarly positive results can be expected from cost product analysis. To understand this whole cycle of events, the definition of energy has to be understood in detail along with its units and forms.
Definition of energy:
Robbins briefly defines economics as a traditional science. The definition we are all familiar with but based on it is given as a temporary definition of energy economics. "Electric economics is a science that deals with technical disciplines, science, economics and management. The study of productive generation and human behavior has been studied here. . "
Conventional electrical inventions that work to generate electricity as defined above. The use of these limited power resources in such a way as to enable them to generate more and longer power, according to the study of Books, will be as much as the current use of conventional power research in the present thirty to forty years. And so it will be very difficult to generate electricity. Thus, if non-conventional research like this is used more in the field of power generation, we can slightly extend the life span of the energy required for this structural requirement. This study gives an explanation of economic matters. Energy is used when work is done. Work only happens when that energy is used. Work can only be done when energy is converted from one form to another. Energy cannot be produced or destroyed. But non-efficient use requires energy expenditure. In a nutshell, "energy is the factor that makes any action possible." It takes strength to work. We feel tired when we work all day. That is lack of strength. Then we eat the food we need to regain energy. Energy is produced when this food is digested. This power becomes useful to work. It can only be acted upon if any substance has power in addition to matter. Or the act of exerting force on an object is stored in it as a force. This exchangeable action is called Shakti. Work cannot be assumed by an object or object, but power can be assumed by an object or object. The energy that is used to perform all these actions is called "energy" in scientific language. The word power for energy has become more prevalent in general practice.
Thus people generally use Power and Energy as synonyms. But there is a big difference. We need brief information.
"Energy is the power to act" and "power is the power of a person or a machine to perform a task in a given unit of time." Thus power is measured in terms of time. Thus power is the rate of doing something. This is the rate. Energy varies from one form to another. Power therefore represents the rate at which energy is used. When an object has the ability to function, it is said to have energy. Both energy and work are measured in a single unit. While the unit of power is used in watts, horsepower, calorie seconds and the British thermal unit.
Definitions of units of energy:
Energy is the ability to work, hence it is also called work force. Thus the units of energy and work are one and the same. The amount of energy in various forms as shown above is expressed in different methods or units. Biologists and chemists measure energy in grams of calories or kilograms of calories. Energy is measured in British thermal units (Btu) in sub-instruments. In addition, energy is sometimes expressed in units of fuel. Thus some essential units can be defined as follows.
Forms of energy:
- Mechanical energy
- Heat energy
- Chemical energy
- Gravitational energy
- Nuclear energy
- Solar energy
- Electrical energy
are various forms of energy.
Mechanical Energy

The energy produced due to the motion of inert objects arranged next to each other is called 'mechanical energy'. In earlier times when a heavy object had to be moved it took a lot of labor to move it. People have realized over the years that putting round pieces of wood under a heavy object reduces the labor required to move it. Humans were first introduced to the use and benefits of mechanical energy in this way. This is how chakras were invented and as a result wheeled vehicles and finally various types of machines came into existence, evolved over time and developed modern machines.
Heat Energy

Atoms in the structure of matter are always in motion. This kinetic energy in them reflects the value of the heat energy stored in it in the form of the temperature of the object. By burning wood and inert fuels like coal, petroleum, gas, etc., the energy stored in them can be converted into chemical energy in the form of 'thermal energy'. Primitive man saw fire erupting in the collision of stones or in the forest, rubbing the branches of trees together. On top of that he used fire to roast meat and remove darkness - thus 'heat energy' was first used for cooking food. At present, heat energy is used not only for cooking, fueling, lighting, but also for generating mechanical energy to run vehicles and equipment. Immaterial fuel is also used to generate electrical energy.
Chemical energy

Chemical energy is the binding force created by their electric charges to hold atoms together in the atoms of matter. In the process of photosynthesis, 'solar radiation energy' is converted into chemical energy. Which are stored in the growing plant cells. Chemical energy is converted into electrical energy in a simple cell and in a fuel cell. At present this energy is being used mostly to generate 'thermal energy' and 'electrical energy'.
Gravitational Energy:

Gravitational Energy After Newton's discovery of the gravitational force, the perception of this energy pervading the world came to man.
The positional energy in every object on earth is due to the 'water-potential energy' stored in the water at high altitudes and the energy stored in the ocean water at high tide.
Nuclear Energy

Is. In 1906, the well-known scientist Einstein proved with evidence that matter and energy in matter are basically two forms of the same physical zodiac. And the relationship between them can be denoted by the formula E = MC2. Now that this formula has been proved experimentally, energy is released as soon as mass is converted into energy during the atomic processes of atoms. This energy is obtained in abundance and cheaper than the energy received in other ways. But since the 'radioactive waste' generated at the time of its acquisition is destructive to living things, there are many dangers in overproduction of this energy. Currently this energy is used to generate electrical energy. If this energy is used only in creative works, it will be very useful to mankind. E.g. Atomic energy produced from uranium, thorium.
Solar Energy

The energy emitted from the sun in the form of visible light, translucent, ultraviolet and other electromagnetic radiation is called 'solar radiation energy' or 'solar energy'. Of these, the radiation to which our eye is sensitive is what we call 'light'. The existence of all kinds of living things on earth is due only to solar energy. The direct use of solar energy is slowly gaining ground. Since solar energy is an inexhaustible and pollution-free energy, there is no doubt that it will be very useful when its practical use becomes fully possible.
Electrical Energy

| Electrical energy |
Electrical energy is the energy that arises due to the potential of electricity stored in electric loads and is useful as an electric current. Ever since a scientist named Fleming rubbed glass rods with silk to create the first state of electricity, electrical energy for man came into existence. Dynamo or 'generators' are currently used to generate large amounts of electrical energy by modifying flux lines in a magnetic field. Since electricity is an excellent type of energy conductor (both in terms of speed and proportion), they are first converted into electrical energy for practical use of the above other energies. In today's age 'electric energy' has become a very important part. The use of which has become indispensable in every field of modern man.
