As you know, energy is very important for our lives. We need energy to live and to work. If there isn't energy, our lives will be very difficult. However, the natural resources are being used up. So we should know how to save energy in the three following ways: First: how to save water. Second: how to save electricity. Third: how to save petrol or gas. As for me, we should save water by taking a shower instead of a bath; using less hydro. We should save electricity by turning off the lights, TV, air conditioner,...before leaving the room; using low energy light bulbs. To save petrol or gas, we should use public transport for short trips; try walking or cycling instead of using cars or motorbikes; using less gas when cooking. To sum up, we should save energy because to save is also to money as to as natural resources.
