• Energy and types• Renewable and non renewable sources• Resources

EnergyIs the ability to

do work or cause change

Can be

Transformed (from one type to another)

Transfered (from one body to another)

Stored

Transported (from one place to another)

Types of energy

Chemical energy: stored in food, plants, batteries….

Light energy: is emited by objects that emit light

Nuclear energy: is gave by chemical elements

Mechanical energy: when it produces movement

Thermal energy: is released by object as heat

Electrical enegy: is used by electrical objects

• Chemical energy. It is the energy given by food, batteries or fuel.

• Light energy. This is the energy of the objects that give light, like the sun or the light bulbs.

• Nuclear energy. It is the energy given by chemical elements such as uranium and plutonium.

• Mechanical or kinetic energy. Objects moving have this kind of energy. For example, a car riding.

• Thermal energy. It’s the energy that emerges from an object as heat, for example from a stove.

• Electrical energy. It is the energy used by electrical objects, such as mixer or a computer.

Energy resources
