We use many different energy sources to do work for us. Energy sources are classified into two groups - renewable and nonrenewable. Non-renewable energy sources are those that take millions of years to form and will run out some day. It is energy that comes from fossil fuels such as coal, crude oil, and natural gas. Fossil fuels are mainly made up of carbon and were formed millions of years ago. The chemical reaction which takes place when we burn fossil fuels releases carbon compounds such as carbon monoxide and carbon dioxide into the air. Carbon dioxide is one of the green house gases which is contributing to global warming and air pollution. On the other hand, renewable energy sources will never run out, are better for the environment and do not cause pollution. Renewable energy is often called green energy because it is a natural energy, always available and does not have to be formed like nonrenewable energy. The green energy is always there. For example, the Sun consistently shines, water is abundant, and the winds blow throughout the year. The five types include solar, energy from the Sun; geothermal, energy from heat within the Earth; hydroelectric, energy from moving water; biomass, energy from dead plants and microorganisms and finally, energy from the wind.

Anna is very self-deprecating, her back has two very obvious scars, running from her neck to her waist, so she is afraid every time she has to change clothes.Especially when it comes to PE class, while the other kids happily change into tight uniforms and wear more comfortable gym uniforms, Anna always quietly hides in a corner, leaning against the wall, try to change clothes as quickly as possible, lest anyone see.But, some time later, Anna's scar was finally discovered by the children."Fear!" "Monster!" Innocent words, absolutely no malice but hurt others, little Anna cried because of her friend's words.Knowing the story, Anna's mother took her to meet her homeroom teacher.Mother said: "Having just been born, Anna was seriously ill, the family sometimes thought of giving up, but had to accept, anyway, it was a life, how could it end like this."My mother told me she was going to cry. "Fortunate to meet a good doctor, thanks to the surgeon she had a chance to live, but she left two very large scars."Mom turned around and called Anna: "Come over here, show it to the teacher".Anna hesitated for a moment, then also took off her shirt, the teacher saw two scars, both surprised and heartbroken asked: "Does it still hurt?"

Anna shook her head and replied, "No teacher

The teacher kept thinking, as long as she banned the students from teasing Anna anymore, that would only solve the surface of the problem, not the root cause, Anna would still be so self-deprecating, Yes think of a better way. Suddenly, an idea flashed in her mind, the teacher patted Anna's head and said: "Tomorrow gym class, you can change clothes with your friends."

With crystal-clear tears rolling down her cheeks, Anna replied to her teacher: "But you'll probably criticize me and say I'm a monster."
