Introduction
Energy is the lifeblood of the modern world. Without energy, we wouldn’t be able to power our homes, transport ourselves to work, or do most of the things we take for granted every day. But where does this energy come from? What are the sources of energy? In this article, we will take a look at the sources of energy class 10 students need to know.
Renewable and Non-Renewable Sources of Energy
When it comes to sources of energy, there are two main categories: renewable and non-renewable sources. Renewable sources of energy are those which can be used again and again. These are often referred to as “green” sources of energy as they have less negative environmental impacts than non-renewable sources. Examples of renewable sources of energy include solar energy, wind energy, hydro energy, geothermal energy, and biomass energy.
Non-renewable sources of energy, on the other hand, are sources of energy which cannot be replenished. These sources of energy are finite and will eventually run out. Examples of non-renewable sources of energy include coal, oil, and natural gas.
Renewable Sources of Energy
Solar Energy
Solar energy is one of the most popular renewable sources of energy. It is energy that is generated from the sun’s rays. Solar energy can be used to generate electricity, heat water, and even power vehicles. Solar energy is becoming increasingly popular due to its ability to generate clean, renewable electricity without the need for fossil fuels.
Wind Energy
Wind energy is another source of renewable energy. It is energy that is generated from the wind. Wind turbines are used to capture the wind’s energy and convert it into electricity. Wind energy is becoming increasingly popular due to its ability to generate clean, renewable electricity without the need for fossil fuels.
Hydro Energy
Hydro energy is energy that is generated from the power of moving water. This can be generated through the use of dams, turbines, and other methods. Hydro energy is becoming increasingly popular due to its ability to generate clean, renewable electricity without the need for fossil fuels.
Geothermal Energy
Geothermal energy is energy that is generated from the earth’s heat. This energy can be harnessed and used to generate electricity, heat buildings and water, and even power vehicles. Geothermal energy is becoming increasingly popular due to its ability to generate clean, renewable electricity without the need for fossil fuels.
Biomass Energy
Biomass energy is energy that is generated from organic matter. This can include wood, crop waste, and other organic materials. Biomass energy is becoming increasingly popular due to its ability to generate clean, renewable electricity without the need for fossil fuels.
Non-Renewable Sources of Energy
Coal
Coal is a non-renewable source of energy. It is a combustible black or brownish-black sedimentary rock that is composed primarily of carbon and other organic materials. Coal is used to generate electricity and heat water.
Oil
Oil is a non-renewable source of energy. It is a combustible liquid that is composed of hydrocarbons and other organic compounds. Oil is used to generate electricity, heat water, and power vehicles.
Natural Gas
Natural gas is a non-renewable source of energy. It is a combustible gas that is composed of methane and other hydrocarbons. Natural gas is used to generate electricity, heat water, and power vehicles.
Conclusion
For class 10 students, it is important to understand the sources of energy. In this article, we have looked at the two main categories of sources of energy: renewable and non-renewable sources. We have also looked at some examples of each type of energy source.
It is clear that renewable sources of energy are becoming increasingly popular. These sources of energy are clean, renewable, and have less negative environmental impacts than non-renewable sources. It is important for class 10 students to understand the sources of energy and their uses.
