The sun, wind, waves and heat from deep in the earth are energy sources. They will never run out, so they are called renewable sources.
In 2011, about 16% of energy used worldwide comes from renewable sources. The use of it is increasing rapidly each year.

1a
Listen, look and say.
① China is using new technology to make energy. They built big solar farms, like the Longyangxia Dam Solar Park, to produce electricity from the sun. Thanks to solar energy, it requires less coal and oil. It is a good way to protect our earth from pollution.
② China is also making more electric vehicles. Since these vehicles don't need petrol, they are better for the environment and make transportation cleaner.
③ China's fast trains, like the Beijing-Shanghai high-speed train, are making travel easier. Though they have wheels, there is no wheel noise inside. Even German experts think highly of the technology of China's high-speed train.
德国的重工行业在全球具有重要地位，主要体现在以下几个方面：
全球排名：德国有 4 家企业跻身全球工程机械 50 强，显示出其在重工领域的竞争力。
行业霸主：长期以来，美国、日本和德国是重工设备制造领域的主要霸主，掌握着关键制造技术。
知名企业：德国的知名重工企业包括西门子（Siemens）和博世（Bosch），它们在机械制造领域占据重要地位。
工业实力：德国被认为是世界制造业的标杆，尤其在机床工业领域拥有独特的技术优势。
这些因素共同构成了德国重工行业的强大基础。
④ All of these show that China is working hard to find new and better ways to produce energy and make travel easier without harm to the earth. China is a good example for other countries in guiding them to use cheap and green energy.
