Have you ever wondered how the electricity that powers your lights, TV, and computer is made? Let’s explore how electricity is generated and the different methods used to produce it.
Most of the electricity we use comes from machines called generators. These generators create electricity when turbines spin. But what makes the turbines spin? There are several ways:
Once electricity is generated, it needs to travel from the power station to our homes. This is done through electric cables. These cables can be seen on tall structures called pylons or sometimes buried underground.
Different countries use various sources to generate electricity. Most of the world’s electricity comes from burning fossil fuels. However, there are other sources too:
While fossil fuels are a major source of electricity, they have some drawbacks. Our reserves of these fuels are running low, and burning them releases carbon dioxide, which contributes to global warming. Because of this, many countries are looking for ways to use more renewable energy sources.
Understanding how electricity is generated helps us appreciate the energy we use every day and the importance of finding sustainable ways to produce it.
Gather some basic materials like a battery, a small light bulb, and wires. Try to create a simple circuit that lights up the bulb. This will help you understand how electricity flows and powers devices.
Using materials like paper, cardboard, and a small motor, build a model of a wind turbine. See if you can generate enough electricity to power a small LED light. This activity will show you how wind energy can be converted into electricity.
Choose a renewable energy source such as solar, wind, or hydroelectric power. Research how it works and create a presentation to share with the class. This will help you learn more about sustainable energy options.
If possible, take a virtual or in-person tour of a local power plant. Observe how electricity is generated and distributed. This will give you a real-world perspective on the concepts you’ve learned.
Create a poster that encourages people to conserve electricity. Include tips on how to save energy at home and why it’s important. This activity will help you think about the impact of electricity use on the environment.

We use electricity without even thinking about it. But how is it made? What processes are involved in generating the electricity that powers our lives? Most electricity is generated by rotating turbines connected to generators that produce an electric current. The turbines are commonly driven by steam, but they can also be powered by water, wind, waves, or hot gases.
Steam can be produced in several ways. One method involves boiling water by burning fossil fuels, biomass materials, or through nuclear fission in a nuclear plant. Another way to produce steam is from geothermal resources, where hot water or steam under pressure in the Earth’s crust emerges from the ground and drives a turbine. Additionally, steam can be generated from a fluid heated by the sun, known as solar-thermal power.
The electricity produced is distributed from the power station through electric cables, carried on pylons above the ground or sometimes underground, to where it is needed, such as in homes. Although it may differ between countries, most of the world’s electricity is generated from fossil fuels, including coal, gas, and oil. Hydroelectric power produces more energy than nuclear resources, while power from renewable sources such as wind and solar currently generates the least.
The challenge with using fossil fuels for electricity generation is that our reserves of these resources are depleting, and burning them releases significant amounts of carbon dioxide, which contributes to global warming. As a result, many governments worldwide are seeking ways to dramatically increase the use of renewable energy sources.
