Approximately 300 TW of the solar energy striking the Earth’s surface is converted to kinetic energy in wind.
Wind power is now the world’s fastest-growing energy source and has also become one of the most rapidly expanding industries.
It is predicted, in 2030 energy comes from renewable sources be 28% of total generation. Wind energy will be the second largest accounting for 27% of green resources.
Wind turbines convert the wind’s kinetic energy to electricity without any emissions. It has become the least expensive new source of electric power in the world.

A compact reversible horizontal turbine has been developed by French Engineer which acts with equal efficiency both as a pump and as a turbine.
When the power demand on the system is low during the rising tides, the unit operates as a pump to transfer water from the sea to the basin.
When the load on this system is high, the unit will work as a generator and deliver the stored energy which is a valuable additional input to the system.

There is a very consistent relationship between the cost of solar PV panels and the deployment of solar PV panels. It is known as Swanson’s law: “Every doubling of production and shipments of solar panels, there has been a 20 percent reduction in the cost of panels”.

See lessThere is water on the floor, a cloth absorbs the water, then the cloth is crushed/wrung out to remove the water.
For AC, the water is the heating of the house, the cloth is a kind of chemical, which is called refrigerant.
The refrigerant absorbs the heat, then the refrigerant is crushed/twisted to expel the heat from the refrigerant outside the room. A machine called ‘compressor’ works to compress/compress the refrigerant. As the name suggests, it compresses. By the way, the fridge works the same way.
Refrigerant is in liquid and gas state in different parts of AC. By absorbing heat, it becomes a gas, compressed in a compressor and becomes a liquid again.
What is passive components in electronics? Why are they?
Before starting let's give an example. Let's talk about a bicycle and a motorbike. We don't need to turn on a bike to ride or operate it. We can work with it whenever we want.

Before starting let’s give an example. Let’s talk about a bicycle and a motorbike. We don’t need to turn on a bike to ride or operate it. We can work with it whenever we want. That is, its religion is such that it is always active. So we can call it an active device. But what happens in the case of a motorbike? The bike must be switched on to operate it. Moreover, it is not able to move or work. That is, it is not always integral. So we can call it, an active device.
In electronics, the concept of active and passive is the same. There are some components in electronics that don’t need to be turned on beforehand to make them work. They are always active. We can use them whenever we want. We call them passive devices. Again, there are many components that need to be turned on like a bike for use. We call them active devices.
There are only three passive devices in all electronics. namely-

Weight is defined as the amount of upward force acting on an object at a given level. A freely falling object has no surface to exert an upward force on it. Hence the weight gap appears.

Man is a single organism. Living body is made up of cells and tissues. They are made up of proteins, lipids, water and various organic compounds. Proteins are made up of carbon, hydrogen, oxygen and nitrogen as a complex compound. So are lipids. It also contains small amounts of Sulphur, iron, copper, zinc, gold, silver, magnesium, molybdenum. All these are found in varying degrees in any living organism, not just humans.
Therefore, in the language of science, man is made of all these things. Soil does not contain hydrogen, oxygen and nitrogen. So man is not made of clay alone.
