Hello Gaurav

Human power is the work or energy that is produced from the human body. The world today has developed into a much better place with our life getting comfortable due to the presence of new and updated technologies and that has been possible because of humans. It is the humans who uses their mental power to invent new technologies, to build new machines. Things don't work themselves, human resource is must and that's why they are termed as the biggest asset.

I hope it helps you

Best wishes for your future.
