We use a lot of electricity in our daily lives. Electrical energy is converted into light, heat, motive power, etc. and is used in a variety of situations outside of the home, including offices, factories, and transportation infrastructure such as trains.
To produce that electricity, it is essential to generate electricity. There are various methods for generating electricity, but most power plants use steam turbines to generate electricity, and boiler feed pumps to send high-temperature, high-pressure water to the boiler to create steam. Without these machines, electricity would not be generated and the convenience of using electricity would not be possible.
