Are we doing enough to sustain our environment?

I am going to talk about "We use the solar energy to replace coal resources."

In the past of China, people used coal to keep warm in their family, but coal is an non-renewable resource and it polluted air.

Now, most families in China use the solar energy to replace use coal to keep warm, because solar energy has many benefits, such as solar energy is a nature renewable resources, it does not damaging the environment and people use the solar energy can also salved money. For example, a lot of Chinese family use solar water heaters to replace gas water heaters, because solar water heaters are used solar energy. It does not need gas resources, so people can pay less on their gas bills. Also, using solar water heaters is more green initiative than using gas water heaters.

Except that, the solar energy also used to generate electicity in China. For instance, we have many solar power stations and solar street lights. Using solar energy helps us saving many non-renewble resources and makes the environment  getting better and better.
