In classroom we talked about the 50/50 project and what we could do to save the energy. When we come to school on the morning, we have to open the window blinds so that the sun can warm the class. And at the end of the day window blinds must shut off to keep the cold out. We have to put lights off every time not needed (in toilet and in shower). We can save water by taking shower quickly. We named persons in charge who take care of these actions.
Every time we wash our hands we have to remember that faucet is not at maximum and we take only one paper when drying hands. Persons in charge also double-check that there are no unnecessary lights on in classroom and they switch off every electric machine after the school day.
