Electricity Generation 101- Part 1

We all think we know the answer to this: How many people does it take to turn on a light bulb. One, right? That’s partially true, but the real answer is much more complex because it takes many people to generate and deliver power.

In order for us to learn how electricity is generated we must look at the source. Nature has provided us many sources of electricity generation. The planet provides us with coal and natural gas—types of fossil fuels–to water in the oceans and rivers, the building blocks of hydroelectric power. There are other forms of power too, like wind power generated from windmills. Even uranium, which we use in the process of splitting an atom in a nuclear power reactor. We also have the ability to harness the energy of the sun so we can create solar energy. While the planet provides an abundance of sources of energy, not all of them will last forever. Energy that can be reused repeatedly is known as renewable energy. This includes wind, solar power, hydroelectric power, etc. Energy created from a limited source such as fossil fuel is known as finite energy source.

It is not enough to have the sources of energy available. Power generation requires a chemical or mechanical process to help transform it into useable electric energy. Today most of our energy comes from thermal power plants as coal, natural gas or petroleum can heat up the water in the turbine until it produces steam, which powers a turbine and generates electricity. The generator inside the turbine converts the mechanical energy into electric energy. This way is efficient because the water can be cooled down again and can be reused in this process over and over again.

While this covers the basics of how electricity is generated, transporting this energy to your home is an entirely different process that we will explain later on.
