1. The Advantages of Clean Energy Sources (Lợi ích của năng lượng sạch)
2. Comparing Different Energy Sources (So sánh các nguồn năng lượng khác nhau)
Choosing the best option for energy can be difficult. Coal power is the most popular form of energy today because coal plants aren't expensive to build. However, they can produce a lot of pollution. Other non-renewable energy sources, like natural gas, are cleaner than coal, but they still aren't good for the environment.
Countries are now moving to renewable sources of energy like wind, solar, and hydroelectric power.
Wind and solar power plants are clean and cheap to run, but they aren't cheap to build. Also, wind turbines are noisy and need windy weather to work well, and solar power doesn't work at night. Hydroelectric plants also don't cause pollution, but they can be expensive to build and affect the environment by stopping fish from moving freely. For these reasons, countries and cities usually choose a mix of energy types.
