WHAT ISENERGY ?

• Energy is the ability to do work or cause change. It comes in various forms, like heat, light, and motion, and can be transferred or converted but never created or destroyed.

During the stone age, it was wood. During the iron age, we had coal. In the modern age, we have fossil fuels like petroleum and natural gas. So how do we choose the source of energy?

The main examples of non-renewable resources are coal, oil and natural gas. There are two types of natural sources of energy classified by their popularity and use:
• Conventional Sources of

1. Conventional Sources of Energy These are the traditional energy sources that people have used for a long time. They are usually non-renewable, meaning they can run out if we keep using them. They have been very important for powering our homes, factories, and vehicles, but they can also harm the environment by causing pollution. Fossil Fuels (coal, petroleum, natural gas) Hydropower Nuclear Energy Example:

2. Non-Conventional Sources of Energy These are newer or alternative energy sources that are better for the environment. They are usually renewable, meaning they won't run out because nature replenishes them. These sources are becoming more popular as people look for cleaner and more sustainable ways to produce energy. Example: Solar Energy, Wind Energy Geothermal, Energy, Biomass Energy, Tidal Energy
