Frequent question: What is generation of energy?

The process of producing electric energy or the amount of electric energy produced by transforming other forms of energy into electrical energy; commonly expressed in kilowatt-hours (kWh) or megawatt-hours (MWh). View on Wikipedia.

What is the need of generation of electrical energy?

Electricity is an energy currency, rather than an energy source, which means that electrical generation needs to start from a primary energy source like a fuel or a primary energy flow. These fuels and flows are usually turned into electric current which transmits electric power to the grid.

What are the 3 types of power supply?

There are three major kinds of power supplies: unregulated (also called brute force), linear regulated, and switching. The fourth type of power supply circuit called the ripple-regulated, is a hybrid between the “brute force” and “switching” designs, and merits a subsection to itself.

GOOD TO KNOW:  Does co op top up gas and electric?

Why do power stations generate AC and not DC?

The power station generates AC and not DC because the transmission of alternating current is easier and very efficient. The transformers can step up and step down the voltage of the alternating current.
