II.Write a short paraghraph about what we should do to save energy.

Energy is very important for our life so saving energy is the most important acts. Saving energy means decreasing the amount of energy used while achieving a similar outcome of end use. Using less energy has lots of benefits – you can save money and help the environment. Generating energy requires precious natural resources, for instance coal, oil or gas. Therefore, using less energy helps us to preserve these resources and make them last longer in the future.Nearly all everyday products have an impact in terms of energy, especially when you consider their energy requirements across the whole life-cycle: production, use and end-of-life. In many cases the use phase is dominating. Plastics, for example, are one of the most resource-efficient materials available. In their use phase, plastics products help to save more energy than is needed to produce them: For example, when you choose a bottle of water packaged in a light weight material such as plastic, remember that lighter packaging requires less energy for transport. Thus, less fuel was used to power the truck that delivered those plastic bottles.There are many sources on the web that give you ideas of what you can do to save energy. Here are a few ideas to get you started:First,Change your travel behaviour, think more in terms of public transportation, if possible, walk or ride your bicycle instead of taking the car.Second,Reduce your house heat by 1C, keep the windows closed while heating, dress warmly .Third,Choose products that come with lightweight packaging.Fourth,Turn off lights and appliances when you are not using them, use energy-saving light bulbs.Fifth,Reuse plastic bags for shopping and storage.Finally,Use rechargeable batteries instead of disposable batteries.Now, the enerergy wil be saving
