​Discuss and and prepare a short talk about the following questions:

​

​What is the most powerful renewable energy that people will use commonly in the future?

​

​List the benefits it brings to people's lives.

​I think solar energy is the most powerful renewable energy in the future. Because:

​- If we use more solar energy, the air will become cleaner and our health will be better.

​- Solar energy can also be used for day lighting, cooking, heating water, and helping plants grow. If we have solar panels on our roofs, we'll be able to generate our own electricity. 

- If people use renewable energy, their impact on the environment is less.
