We use energy in everything we do. Using so much energy make the atmosphere change, the earth to heating up. We should use energy wisely. Ride a bike or walk instead of driving. Turn off lights, TV, computers when not in use. Do not use a motorbike or car to go to nearby places. Those little things can save us a lot of energy!
