Well, saving energy have a lot of ways. We could use energy-saving light bulbs, our car can also replace our fuel to natural gases. We could also turn off applications if not in use. Reduce, reuse and recycle is also very important in helping us saving the Earth. We all must repent before it is too late and the consequence would be dire too.
P.s. Sorry teacher, I was busy doing other Homework too and thus i did not really pay much attention to the deadline's time.
