Hello, class. Today I'd like to tell you about two energy sources. They are non-renewable sources and renewable sources. Non-renewable sources are coal, oil and natural gas. We can use these sources to produce energy. They are cheap and easy to use. People use them a lot. But they are very limited and will run out soon. Renewable sources come from the sun, wind or water. When energy comes from the sun, we call it solar energy. Wind energy comes from the wind, and hydro energy comes from water. Renewable sources are available, clean and safe to use. But they are expensive to produce. In the future we will rely more on renewable energy sources. They are better for the environment and they will not run out.
