• 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
Can be
RenewableNever run out
Non- RenewableRun out
Sun: light and thermal energy
Wind: mechanical energy
Flowing water: hydraulic energy
The Earth´s internal heat: geothermal energy
Biomass: Chemical energy
Fosil fuel
