Nowadays, energy is being run out more and more so what should we do to save energy?
First, we should use electricity more efficiently. We should turn the light, the television and other electrical appliances off when we are not using them. We can also use low energy light bulbs to save electricity.
Second, we should use less private transport. We should travel by bus or train instead of car and motorbike. In addition, we can avoid using cars or motorbikes for short trips.
Finally, we should reduce the use of water. Taking showers instead of baths is a good way. Besides, we should turn off the tap when brushing our teeth; this can save 6 liters of water per minute.
In conclusion, those ways can save our lives in the future so we should raise our awareness of saving energy.
