Oh no! I hate the sun, mother! It burns!

Honey, you should not hate the sun, the sun is good and important for us.

Once upon a time there was a girl named Carmela who was afraid of the sun because she had sensible skin and every time she was exposed to the sun her skin burned, this made her believe that the sun was bad for human beings.

Her mother told her it was important for her to understand the importance of the sun.

Mommy can you explain why the sun is important?

Sure Carmela, see...

Plenty of buildings and factories use solar panels today, Carmela.

Later at home her mother explained to her that the sun can produced energy, which is produced from the solar radiation into electricity.

This type of energy is better because it is renewable energy that does not pollute and it can reduce your bills.

It can produce electricity or heat. The only disadvantages were that it only works during the day because the energy is obtained from the sunlight, that is why some cold weathers can't use solar energy.

I hate the wind now! Mom, look at my hair now!

A few days later Carmela and her mom went on cruise. Carmela had spent all morning brushing her hair. When se went out, the cool breeze of the wind blew her hair and it was ruined.

Carmela was completely angry with the wind and told her mom how much she hated it.

Carmela, the wind is good! It's also a friend of us and the environment!

Perhaps Mr. Wind didn't intended to ruin my hair!

Conchita, Carmela's mom told her that the force of the wind could be transformed into electicity.

Mr. Wind produced free breezes and did not produced greenhouse gases.

However it had some disadvantages such as irregular breezes and very noisy turbines installed in farms and agricultural fields.

While on the cruise, Carmela wondered if the ocean waves could produce energy, like Mr. Wind. She went to ask the capitain and he said:

Oh yeas dear! The ocean is amazing and helps us produce clean energy!

The magnificent ocean produced to types of energy: thermal with the help of the sun and mechanical with its beautiful waves. When vaporization occurs, some turbines are able to move. Mechanical devices were also intalled in the ocean so the waves powered them on.

As always, the energy was polluting free, low maintennance and worked no matter what the climat conditions are. However, the ecosystems may seem affected by the equipment used.

Carmela and Conchita came back from the cruise and went camping. Carmela almost fell into the rapids. She was very scared.

And she got mad as always. Conchita gave a little laugh at her daughter.

Rivers are horrible! I almost died!

The force of rapids help produce hydroelectric energy, Carmelita. Another renewable energy.

You mean it's friendly with en environment?

Back at home, Conchita explained to her how rapids were also so important to humans.

The force of the running water produced electricity with the help of some turbines. Water was never taken away during the process and it could function 24/7.

However hydroelectric plants are very expensive and may cause floods.

Hydroelectric plants could produce electricity around the whole country and all around the world.
