2  What is energy?  Laws of energy.  Forms of energy.  Sources of energy.  Types of energy.  Using and saving energy.

3  Energy is the ability to do work. Energy is found everywhere in the world and comes in many forms.

4  “Energy is neither created not destroyed. It changes from one form into another”  “ You can´t see energy, you just can see it´s effects or the changes it produces”

5  There are two forms of energy:  Potencial energy: the energy stored. Chemical energy as the one in batteries is an example of potential energy.  Kinetic energy: Is the energy in motion.Thermal energy and wind energy are some examples of kinetic energy.

6 TThere are two main sources of energy : renewable and non-renewable sources of energy.

7  Renewable energy is the energy that we can reuse over and over again, wind, water, sunlight…  Non-renewable energy is the one that is produced from animals and plants remains and it needs million and million of years to replenishes.

8  Types of energy: Electrical energy: is the energy produced by the flow of electric change. Chemical energy: is the energy produced by fossil fuels and biomass. In our bodies, it is the energy produced by the food we eat. Mechanical energy: is the energy produced by things in motion. Thermal energy: is the energy released as heat.

9  Nuclear energy: is the energy found in chemical elements, like uranium and plutonium.  Light energy: is the energy found in light, mainly the sunlight.

10  We can save energy:  Using efficient electric bulbs.  Closing the window when the heater is on.  Opening the window when there is sunlight.  Closing the tap when we are brushing our teeth.  Recycling paper.

11  Done by :  Víctor Merino  Marina Frontela  Jesús Lozano and Melissa Heras
