(Brainstorming) to save or not to save

The document discusses the results of a survey given to students about saving energy. It finds that most students understand that saving energy means not wasting it, but they focus only on the economic benefits and do not consider the environmental impacts. While students agree that traditional energy sources have negative effects, they are unclear on the different environmental impacts of traditional versus renewable energy. The survey also examines students' individual energy saving habits and finds room for improvement in practicing more efficient behaviors.
(Brainstorming) to save or not to save
- 1. BRAINSTORMING ABOUT SAVING ENERGY That’s the question IES La Arboleda 2013 (Lepe, Spain) 1st Bachillerato Comenius students and teachers: Ph Guadalupe Luna Sánchez Ph Vicente Maroto Falconet Ph Patricia Piñero Rodríguez Ph Mª Ángeles Capela Torquemada
- 2. In order to get information about the level of knowledge of our students with respect to the concept of saving water and energy, several questions were proposed. After being answered individually, the questions were discussed.
- 4. Survey on Saving Energy BRAINSTORMING What is the meaning of saving electrical energy? Why should we save electrical energy? What is the main disadvantage of the energetic consumption? Do all the energies present the same disadvantages? Which advantages do the renewable energies have against the non-renewable ones?
- 5. Survey on Saving Energy What benefits do we get by saving electrical energy? How important is your individual participation? Why is necessary to save water? What are the main uses of water in our daily life? What is your attitude about the energetic and water consumption in your daily life?
- 6. MAIN CONCLUSIONS Most students considered that saving energy consisted in not wasting ( 41%).
- 7. However, when they were asked about the relevance of this saving they just mentioned the economic aspect, without taking into account the environmental influence.
- 8. Although most of them agreed on the negative effect of the use of some types of energy, they didn't have a clear idea about the different environmental impacts of traditional opposed to eco- friendly energy.
- 9. In fact, when they were asked about the bad points of each type of energy, only 41% mentioned the lower level of incidence of green energy on pollution . The rest made reference to the high cost of alternative sources of energy.
- 10. With respect to individual use, 100% of students admited the relevance of having a pro saving attitude. However only 70% considered that they were saving as much as they could.
- 11. The rest, 30%, thought that they could improve their water and energy saving habits since they were aware of the relevance of this natural resource in our daily life.
