The solar street light makes life better

Have you suddenly discovered at a certain moment that the once faint road suddenly became clear, the lights that once needed coal power to be illuminated were suddenly replaced by the solar street light, and new high-tech began to enter our lives and change our lives. I don't know when, you will often hear the green lighting project. I didn't understand the meaning of this sentence. I suddenly realized that the solar street light is green lighting. The solar street light does not need coal power，and has gone into our lives.
We all know that in the past, Chinese electric energy needed coal and oil conversion. When oil, coal and other resources were converted into electric energy, it would generate a lot of waste, which seriously endangered the living environment of human beings, especially in the industrial age. At the peak of electricity, human beings completely disregarded pollution, and the massive exploitation of oil and coal caused irreversible damage to the natural environment of the earth.
With the continuous understanding of solar energy by human beings, people began to study how to convert solar energy into electrical energy, which was used by human beings. In the continuous exploration, solar water heaters, solar street lamps, solar cars, etc. were developed, which greatly changed the human The living environment has also improved the condition of the earth, and people's lives have become more convenient and better. In the future, we believe that solar energy will be used more widely, and we believe that solar energy will stay with us for a longer time.
