In TEDxKids@PortoSeguroSchool, Carolina talks about the importance of using renewable energy sources in order to preserve the planet.

This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx

Hello, my name is Carol

and today I am here to give
a presentation on renewable energy.

Before I start, I know
some of you may find it strange

having a 10-year-old girl
giving you a class,

but I want you to know
I am not giving a class,

I am just talking to you.

Well, what is energy?

Energy is that which produces
action and movement.

I don't know if you've stopped to think

how dependent we are on energy
in our daily lives, really for everything.

Going about by car.

Making engines run.

Having factories work.

So, as you see, for everything.

To use the mobile,
the computer, the internet.

For really everything in our daily lives.

I will now talk about renewable
and non-renewable energy sources.

What are non-renewable energies?

They are those that become
exhausted with usage,

and they cause big damage
to the environment.

And now renewable energy.

Sources of renewable energy,

they are those that cannot
be created or destroyed.

They renew themselves in a natural way

and cause less damage to the environment.

This is an example of oil, the world's
biggest primary energy source.

This is coal and slate.

This is a nuclear power plant:

radioactive metals
produce heat by a nuclear reaction.

This is an example of natural gas,
the gas used in household cooking.

Now I will talk about renewable energies.

This is an example of wind power:

here the turbine rotates,
generating energy.

This is an example of solar energy:

the sun strikes these panels,
generating energy.

This is a hydroelectric turbine.

And this is ethanol.

As I already said, you cannot
create or destroy them,

they renew themselves
in a natural way as in this photo.

Now it depends on you, I want you
to think of new ideas to save our planet.

Let's save energy in our homes
and in all the places we go.

Thank you.

(Applause)
