This document discusses different types of energy. It describes energy as the ability to transform one object into another. There are several forms of energy, including mechanical, chemical, electrical, thermal, light, and nuclear energy. Energy can change from one type to another, but cannot be created or destroyed. It also discusses renewable energy sources like water, solar, wind and biofuels as well as non-renewable sources like uranium, petroleum, coal and natural gas. The document concludes with tips about conserving energy by turning off devices, lights and using public transport, as well as reducing, reusing and recycling.

2.  What is energy?
 Energy tranformation.
 Non-renewable energy.
 Renewable energy.
 Energy consumption.

3. Energy is the ability to transform an object to an
other.
There are:
 Mechical energy: includes kinetic and potential
energy.
 Kinetic energy: exists as movement.
 Potencial energy: exists as potencial movement.
 Chemical energy: exists certain chemical
substances.
 Electrical energy: form the elctricity.
 Thermal energy: form the heat.
 Light energy: form light.
 Nuclear energy: exists in the atomic structure of all
matter.

4. Energy can change form one type to other. You can´t
create or destroy energy.

5. Non-renewable energy sources of enrgy are limited
because nature dosen´t replace them. They also
cause pollution.
There are:
 Uranium: is a radioactive material that is used in nuclear
power plants.
 Petrolium: is a black liquid that forms undreground.
 Coal: is a black rock that is mostly made of carbon.
 Natural gas: is a mixture of gases that forms naturally
underground.

6. Renewable sources of energy are unlimited decause
they are replaced naturally.
The are also called alternative sources of energy.
There are:
 Hydraulic energy from water that is moving or
falling.
 Solar energy from the sun to head things.
 Biofuels from plant and animal products.
 Wind energy from the movement of air.

7. Energyconservation:
 Turn off electrical devices.
 Turn off lights.
 Use public transport.
The three R´s:
 Reduce.
 Reuse.
 Recycle.
