Today, we will learn about different energy sources. Energy can be classified into renewable and non-renewable sources. Can anyone tell me what 'renewable' means?
Does it mean that they can be replenished?
Exactly! Renewable sources, like solar and wind, can be replenished naturally. Now, can someone define 'non-renewable'?
I think non-renewable sources are finite and won't last forever.
That's right! Examples include coal, oil, and natural gas. Let's remember: 'Renewable = Replenish', and 'Non-renewable = Finite'.
Let's look at some examples of both energy types. For renewable energy, we have solar, wind, and hydro. Can someone give an example for non-renewable?
Um, coal?
Correct! And what about other examples like petroleum or natural gas? Now, does anyone know why we should consider shifting to renewable sources?
Because they're better for the environment!
Absolutely! Using renewables helps reduce pollution and combat climate change!
Now, let's talk about India's energy mix. As of 2023, how much energy comes from renewable sources?
Is it 38%?
Correct! However, we still depend on coal for about 55% of our energy needs. What does this tell us about the challenges India faces?
We need to increase renewable energy use!
Well said! Transitioning to renewable energy is crucial for sustainable development. Remember, ‘38% renewable, 55% coal’ will help you keep track of India’s energy situation.
Renewable sources shine bright, like the sun and wind in flight!
Imagine a tree that grows fruits every year. This tree represents renewable energy. It regenerates and provides endlessly, just like solar energy replenishes through sunlight.
Remember: 'WIND' for Renewable = Wind, Hydro, Solar, Natural.
For Non-renewable: 'CANE' = Coal, Animal Fuels, Natural Gas, Energy, the finite fuels we must reduce.

Energy from sources that are replenished naturally, such as solar, wind, and hydro.
Energy from sources that are finite and cannot be replenished in a short period, like coal and petroleum.
The combination of different sources of energy used by a particular entity or country.
This section compares renewable and non-renewable energy sources and discusses India's current energy mix.
The Energy Sources Table distinguishes between renewable and non-renewable energy sources, providing examples of each while outlining their relevance in India's energy context, which currently features a significant reliance on coal.
The Energy Sources Table delineates the two main categories of energy sources: Renewable and Non-renewable. Renewable sources, such as solar, wind, and hydro, are characterized by their ability to replenish naturally, making them sustainable alternatives. Non-renewable sources, including coal, petroleum, and natural gas, are finite and contribute to environmental challenges.
As of 2023, India has made strides in renewable energy, achieving a 38% renewable capacity; however, it continues to rely on coal for 55% of its energy needs. Understanding these two categories of energy sources is crucial for recognizing the shift towards sustainable energy solutions and addressing environmental concerns.
