What is the main difference between the production of electrical energy and the manufacture of a commodity?

Electrical energy is produced using nuclear energy, while the production of a commodity does not involve nuclear energy.

Electrical energy must be produced and transmitted instantaneously, while the manufacture of a commodity does not have this requirement. (correct)

The production of a commodity requires raw materials to be converted into the desired form over a longer period, while electrical energy is produced instantaneously.

The production of a commodity is based on natural energy sources, whereas electrical energy is not dependent on natural sources.

Which natural sources are mentioned in the text as providers of energy for the generation of electrical energy?

Wind force, electrical pressure, and chemical reactions

Biomass combustion, wave motion, and hydroelectric power

Pressure head of water, chemical energy of fuels, and nuclear energy of radioactive substances (correct)

Solar radiation, geothermal heat, and tidal energy

What is the essential arrangement used to convert various forms of natural energy into electrical energy?

An alternator coupled to a prime mover (correct)

A battery storage system linked to renewable energy sources

A series of transformers connected to a power grid

A generator powered by wind or solar energy

How does the conversion of the chemical energy of a fuel (e.g., coal) into electrical energy occur?
