Which process uses the least amount of material to create electricity, coal or uranium, coal or nuclear power plant?

nuclear power plant

Explanation:

Generation of electricity often involves the use of some kind of material or energy that is consumed as electricity is generated. There are various ways of generating electricity such as;

By burning coal

Use of a radioactive element as nuclear fuel

From wind energy

From water

From the sun, etc

Each process involves the intake of material or energy. The process that goes on in a nuclear power plant requires a radioactive fuel of which uranium is an example.

A nuclear plant uses the least amount of material (such as only 1g of uranium fuel) in electricity generation compared to the tons of coal burnt in order to generate electricity.
