Question

In the modern age, human society runs on energy. Most machines need electricity to operate. Humans cannot live without electricity even a single day in their daily life and work. They have many different ways to create electricity. But some ways are harmful to the environment.

For example, fossil fuels (化石燃料) are the most common kind of energy.They include coal, oil, and natural gas. First, people have to dig them from the ground. This can sometimes harm the environment. However, scientists are creating cleaner and better ways to do that these days. So the environment is not harmed as much as before. But when people burn these fossil fuels, they can give off a lot of harmful gases, which is considered to be one of the greatest causes of global warning. This might harm the environment.

Tidal (潮汐) energy is another way to make electricity. This uses the ocean tides to make electricity. But some kinds of tidal energy can kill many fish and other sea animals. Also dams (大壩) can create lots of clean energy. But dams create lakes and change the way that rivers run. So they can do great harm to the balance of nature around the lakes and along the rivers.

Nuclear (核) energy is a very powerful form of energy. It is cheap. It is also very clean. But many people are afraid of it because it uses radioactive materials. Also, there have been some very serious accidents in the past which caused great harm to human and nature. But the technology is much better these days. so many countries are starting to use nuclear energy more.
