Old Oil Wells Can Get Heat from the Earth

We use energy every day. We use energy for cars and scooters and for machines. 我們每天都會用到能源。 We get most of our energy from coal and oil. But coal and oil make a lot of pollution. Yuck! 這些能源大多來自煤炭跟石油，造成很多污染。 You guys know about solar energy and wind energy. But do you know about geothermal energy? 你聽過太陽能跟風力發電，但你知道地熱嗎？ Geothermal energy comes from the earth. The earth is really hot inside. When you go to a hot spring, you feel the earth's heat. 地球內部溫度很高。你去泡溫泉的時候，感受到的就是地熱。 People have to drill deep into the earth to get geothermal energy, which is expensive! 要使用地熱，就必須挖到地球深處，這樣很貴！ But now a university in America is saving money by using old oil wells, which already go deep into the earth. There is no more oil in them, so Scientists can use them to bring up the heat from the earth. 美國一所大學找到便宜的方法，他們要用乾掉的油井取得地熱。 Wow! That's a great idea! That will make geothermal energy much cheaper. This is exciting! Why? Well, because geothermal energy is like solar and wind energy. It's clean. Plus, you can get geothermal energy even when the sun isn't shining and the wind isn't blowing. That's because the earth is always hot inside! ________________________________ Vocabulary 地熱取之不盡用之不竭，是優良的能源。 1) coal 煤 We use coal to produce power. 我們用煤發電。 But that's not a good idea, right? 那不是個好主意，對吧？ Coal brings pollution. 煤會帶來汙染。 2) hot spring 溫泉 Hey, there are fish in the hot spring! 溫泉裡有魚！ I can't believe it! 真不敢相信！ Yeah, how can they live in a hot spring? 對啊，牠們怎麼有辦法住在溫泉裡？ 3) inside 在裡面 Scientists say it's always hot inside the earth. 科學家說地球裡面一直很熱。 That's why we have volcanoes? 這是為什麼我們有火山嗎？ Maybe.也許吧。 4) oil well 油井 Think about that.
