The Nautilus can go to depths no human has ever reached. It is made of iron and it can bear huge pressure.” 刷速度 返回目录 He led me to a small library. Shelves held thousands of books in different languages. Soft light came from lamps.“Knowledge is freedom,” Nemo said quietly.“Here, I am free.” Suddenly, a low sound spread through the ship.“We are falling down,” Nemo explained.

A huge fish floated past, its arms touching the glass. My heart raced, but the captain smiled calmly, “The sea holds many secrets, Professor. Fear has no place here.” 刷速度 返回目录 Later, in the dining room, we ate dishes from unknown sea plants and fish.“Everything comes from the ocean,” Nemo said.“It provides all we need.” He spoke excitedly about underwater forests.

For example, the Sun helps plants to grow. Plants that grew millions of years ago turn into coal, oil, and natural gas. We call these fossil fuels （化石燃料）. However, fossil fuels make pollution. This is bad for the Earth. Fossil fuels are also non-renewable. Some day they will be gone. So, scientists want people to use green energy. Why is green energy important? First, it is clean. It doesn’t hurt the Earth. Next, it is renewable. It won’t run out. Green energy gives us more than 30% of the electricity we use today. 刷速度 返回目录 19 What are the main sources （来源） of green energy? Water Power Water power uses moving water in rivers and dams. Moving water has energy. Water power makes about 16% of the electricity we use. Wind Power Is wind power new? No, it isn’t.

Biomass energy is green because we plant new trees or crops after we use them. Biomass energy makes about 2% of the electricity we use. 刷速度 返回目录 New Green Energy The ocean rises and falls each day. This moving water can make electricity. We call it tidal power （潮汐能）.There is also heat under the Earth’s surface. Scientists can use this heat for energy, which is called heat power.
