I am looking for mistakes. Introduction The aim of this proposal is to discuss two ideas of conserving energy in a school. The final paragraph will be dedicated to give a recommendation on which one is better. Glass By recycling this matter, we could save a lot of money and time. Glass is special because people can use every bottle over and over again. In my opinion, giving a recycle bin into a school would pay for itself. Solar panels Another suggestion to take into consideration is a solar panel. This device produces energy for free. Therefore, the first investment would not be a bad idea at all. There is a lot of sun above us which gives us energy. This energy could be used to enpower striplights in our school. Heating Finally, it is time to talk about radiators. Many schools including the ours one use old fashioned heaters. What we could do is to exchange the old radiators for new ones. I suppose that this would save 30% of energy. Conclusion All in all, I think that all the mentioned ideas of saving energy are equally important. Recycling glass can be benefitial for us as well as buying some solar panels and radiators. If we apply any of the above mentioned suggestions to reality, then we will certainly save money that is necessary for other issues such us salary for teachers.
