What is Energy?
Energy is the ability to do work or cause change. It can exist in different forms like heat, light, electricity, and motion. For example, when you eat food, your body uses the energy stored in the food to move, grow, and stay warm.
How is Energy Used?
Energy is used in many ways in our daily lives. It powers our homes, schools, and vehicles. Here are some points to understand how we use energy:
- Electricity runs appliances like refrigerators, computers, and televisions.
- Fuel like gasoline and diesel powers cars, buses, and airplanes.
- Our bodies use the energy from food to move and stay warm.
Where Does Energy Come From?
Energy can come from various sources, both renewable and non-renewable. Here are some examples:
- Sunlight is a renewable source that gives us solar energy.
- Wind turbines capture wind to generate electrical energy.
- Fossil fuels like coal, oil, and natural gas are non-renewable sources of energy.
Understanding these sources helps us make better choices about how we use and conserve energy.
