2、Spring is the perfect time to get yourself green. While some may not be able to line their homes with solar panels, there are still simple ways to green up your life.
Light. By now we all know that those spiral(螺旋状的)light bulbs will save energy and even save us money, so why haven' t we done it? Maybe we just don't understand the truly huge effects. Let's do the math; for every 60-watt usual light bulb in the home, there's a better 15-watt or less spiral bulb. The standard two-bedroom home has at least fifteen of them. Changing out all of old bulbs would save 45 watts each, or 675 watts overall.
Food. Growing your own produce is great, but most of us can't grow everything we need. For everything else, there are farmers' markets! Spring is the perfect season to visit farmers’ markets! Supporting local growers is a great way to reduce carbon emissions(排放)produced by growers needing to transport their goods long distances.
Money . If you're still troubling to check the mailbox, consider going paperless. Many organizations now offer paperless billing and statements. They simply send them to any e-mail address that you provide. It's a more convenient way to keep track of those payables and receivables, too. Simply set up an inbox folder(收件箱文件夹)for anything needing to be paid and all of your monthly bills will be at your fingertips at any given moment.
Going green doesn’t just help you; together, it helps everyone. So go ahead, take that first step or second, or third!
