What happens when all the coal runs out to make peoples energy? In case that happens people could use wind energy or even solar energy , but cars can't run on solar energy because they are too heavy. Wind won't work either because it won't take people in the direction they want to go. That is why people use a variety of ways to get their energy. They get the energy from: coal, wind, solar, hydro, geothermal, nuclear, and natural gas. Those are all ways people get energy, but in order to get that energy each one has a different process of making the energy. In order to make hydroelectric energy, water flowing through a dam turns a turbine and that generates electricity. Not all processes are that easy, like energy from coal. First, people have to mine the coal, then they have to burn it in order to make energy. In conclusion, someday there will have to be a different way of making energy, that will work, that doesn't hurt the earth.
