Energy saving campaign (I)

On Thursday 17th a mechanical engineer called Fèlix Mora came to our school. He explained us how to save energy at school and at home. He gave us some tips:

* It's better to have a shower than a bath because we are saving water and electricity at the same time.
* We have to put the dishwasher and the washing machine when they are full.
* We have to clean the light bulbs because they make more light with the same energy.
* We should use natural light, heat and cooling.
* We have to switch off the projectors when we don't need them.
* We should switch off the lights if we are not going to be in the classroom for more than half an hour.
* When we have to buy new light bulbs we should look at the scale energy label and the light they produce (lumen)

It was an interesting and usefuk talk. He was a good communicator because he's also a secondary school teacher.
