Sources Of Energy
key notes :
Introduction to Energy:
- Energy is what makes things work. It allows us to do activities like play, study, and move.
- Energy is needed for all machines and devices to function.
Types of Energy Sources:
- Renewable Energy Sources:
- These sources can be used over and over again and won’t run out.
- Examples include sunlight (solar energy), wind, water (hydroelectric power), and biomass (like wood and plants).
- Non-Renewable Energy Sources:
- These sources will eventually run out and cannot be used again once they are used up.
- Examples include fossil fuels like coal, oil, and natural gas.
Renewable Energy Sources:
- Solar Energy:
- It comes from the sun and can be captured using solar panels.
- Solar energy is clean and doesn’t pollute the environment.
- Wind Energy:
- Wind turbines convert the energy from the wind into electricity.
- Wind energy is eco-friendly and doesn’t produce greenhouse gases.
- Hydroelectric Power:
- It is generated by the flow of water in rivers or dams.
- Dams store water and release it to turn turbines, creating electricity.
- Biomass Energy:
- Biomass is organic material like wood, leaves, and plants.
- It can be burned to produce heat or converted into biofuels.
Non-Renewable Energy Sources:
- Fossil Fuels:
- These are formed from ancient plants and animals.
- When burned, they release pollution and greenhouse gases.
Conservation of Energy:
- It’s important to use energy wisely and not waste it.
- Turn off lights, appliances, and electronics when not in use.
- Drive less and use public transportation, walk, or bike to save energy.
Importance of Using Renewable Energy:
- Renewable energy sources are better for the environment because they don’t pollute and won’t run out.
- Using renewable energy helps reduce climate change and air pollution.
Conclusion:
- Understanding different sources of energy helps us make better choices to protect the Earth and ensure there is enough energy for the future.
