[主观题] 【英译汉】We do not often consider how much energy goes into creating comforts like hot showers and cold beer. A more efficient refrigerator will give us the same cold beer while using less energy. A more water-efficient showerhead will give us the same hot shower while using less water； less water requires less energy. By being more efficient, we use less energy, requiring fewer resources and less money.
We have a lot of opportunities for energy efficiency at home. Whether you are ready to upgrade an appliance to an ENERGY STAR rated model or replace conventional light bulbs with more efficient ones, you will enjoy the same level o£ comfort in your daily life while saving both energy and money.
