ClassX Video Lessons Youtube Channel Smile and Learn English Types of Energy for Kids – Renewable and Non-Renewable Energies
Welcome to our exciting journey into the world of energy! Let’s dive into what energy is, its cool properties, and the different types of energy we use every day.
Energy is what makes things happen. It’s all around us! For example, cars move because of energy from burning fuel. Windmills spin because of energy from the wind. Even when we walk or jump, we’re using energy from the food we eat.
One important thing to know is that energy can’t be created or destroyed. It just moves from one place to another. For example, energy from the air can be turned into electricity, which can then heat a room.
We get energy from two main sources: renewable and non-renewable.
Renewable energy comes from sources that never run out, like the sun, wind, and waves. Here are some examples:
Renewable energy is great because it’s friendly to the environment, doesn’t run out, and is safe for our health. But, it can be tricky because it’s not available everywhere and depends on the weather.
Non-renewable energy comes from sources that can run out, like coal, oil, natural gas, and uranium. Here are some examples:
Non-renewable energy can harm the environment because it releases bad gases and creates waste that needs careful handling. Accidents with these energies can cause big environmental problems.
Energy has some amazing properties:
There are different types of energy, each with its own role:
To help our planet, it’s important to use more renewable energy and less non-renewable energy. This way, we can protect the environment and make sure we have energy for the future.
Thanks for exploring energy with us! Keep learning and discovering more about the amazing world of energy!
Explore your surroundings and identify different types of energy in action. Look for examples of renewable and non-renewable energy sources. Write down what you find and share your discoveries with the class. Can you spot solar panels, windmills, or anything using fossil fuels?
Create a solar oven using a pizza box, aluminum foil, and plastic wrap. Use it to melt chocolate or cheese. Observe how solar energy can be used for cooking and discuss how this relates to renewable energy.
Conduct a simple experiment to demonstrate energy transformation. Use a battery, a small bulb, and wires to show how chemical energy in the battery transforms into light energy. Discuss other examples of energy transformation in everyday life.
Design a poster that highlights the benefits of renewable energy. Include different types of renewable energy sources and why they are important for the environment. Present your poster to the class and explain your ideas.
Participate in a class debate about renewable vs. non-renewable energy. Choose a side and prepare arguments for why your energy type is better. Discuss the pros and cons of each type and how they impact the environment.
Sure! Here’s a sanitized version of the transcript:

[Music] Welcome to our exploration of energy! Let’s discover what energy is, its properties, and the different types that exist.
Energy is anything that has the capacity to produce a change in matter. If you look around, you’ll see that energy is present everywhere. For example, cars move thanks to energy produced by motor combustion. The blades of a windmill start moving due to the energy from the wind. We can walk or jump thanks to the energy we get from food.
It’s important to know that energy can neither be created nor destroyed; it can only be transferred from one object to another. For instance, energy in the air can be transformed into electricity, which can then be converted into thermal energy to warm a room using a radiator.
We obtain energy from two sources: renewable and non-renewable. Renewable energy refers to limitless energy sources present in nature, such as wind, sunlight, or sea waves. Non-renewable energy refers to limited energy sources that we exhaust with use, like oil or coal.
Energy possesses four fundamental properties:
1. Energy transforms: For example, when we use a battery for a flashlight, the chemical energy in the battery transforms into electric energy.
2. Energy is transferred: For instance, when we mix hot and cold water, thermal energy moves from the hot water to the cold water.
3. Energy is transported: Energy travels through electric cables to reach our homes.
4. Energy can be stored: For example, mobile phone batteries store energy.
To recap, energy transforms, is transferred, can be transported, and can be stored.
Thermal energy, also called heat energy, is transferred with heat. Mechanical energy is created by the movement of objects. Electric energy is carried by electric currents. Chemical energy is found in substances like food or fuel. Light energy is present in light.
Renewable energy sources are naturally replenished and include:
– Solar energy, which comes from the sun and can be captured using solar panels to heat water.
– Eolic energy, generated from the movement of air or wind, such as windmills that convert wind into electric energy.
– Tidal wave energy, derived from the movement of sea waves.
– Hydraulic energy, produced by water stored in reservoirs or artificial lakes.
– Geothermal energy, generated from heat stored in the earth, used for heating or electricity generation.
Renewable energies have several advantages:
– They are environmentally friendly, as they do not emit harmful gases.
– They are limitless, as they come from natural resources that replenish.
– They are safer for health, as they do not generate toxic residues.
However, there are disadvantages as well. Renewable energy resources are not found everywhere, and their availability can be variable due to natural phenomena.
Now, let’s discuss non-renewable energy sources. These are limited resources that do not replenish naturally, such as coal, oil, natural gas, and nuclear energy.
– Oil is found underground and is used to produce fuels like gasoline.
– Coal is extracted from mines and produces heat when burned.
– Natural gas is used for heating homes.
– Uranium is used to produce nuclear energy.
Non-renewable energies have environmental disadvantages, such as harmful emissions and the need to manage radioactive waste properly. Accidents related to non-renewable energy can lead to significant environmental catastrophes.
To achieve global energy objectives and protect the environment, it is essential to reduce the use of non-renewable energy resources and accelerate the transition to renewable energies.

This version maintains the core information while removing any unnecessary or repetitive elements.
Energy – The ability to do work or cause change, such as moving an object or heating something. – The sun provides energy that plants use to grow through a process called photosynthesis.
Renewable – A resource that can be replaced naturally and can be used again, like sunlight or wind. – Wind is a renewable energy source because it will not run out as long as the sun shines and the wind blows.
Non-renewable – A resource that cannot be easily replaced once it is used up, like coal or oil. – Coal is a non-renewable resource because it takes millions of years to form and cannot be replenished quickly.
Solar – Related to or using energy from the sun. – Solar panels on the roof convert sunlight into electricity to power our home.
Wind – Air in motion that can be used to generate energy. – Wind turbines capture wind energy to produce electricity without polluting the air.
Tidal – Related to the rise and fall of sea levels caused by the gravitational forces of the moon and sun. – Tidal energy can be harnessed by using underwater turbines to generate electricity from the movement of tides.
Hydraulic – Related to the movement of water, often used to generate power. – Hydraulic power plants use the flow of water to turn turbines and generate electricity.
Geothermal – Related to the heat from inside the Earth. – Geothermal energy is used to heat buildings and generate electricity by tapping into the Earth’s internal heat.
Coal – A black or brownish-black rock that is burned to produce energy. – Coal is burned in power plants to produce electricity, but it releases pollutants into the air.
Environment – The natural world, including the air, water, and land in which people, animals, and plants live. – Protecting the environment is important to ensure clean air and water for future generations.
