The world is increasingly dependent upon energy. Energy powers everything from cars, electricity, to toys. Energy can be divided into two separate categories, nonrenewable energy and renewable energy. Nonrenewable energy is energy produced from nonrenewable resources like oil, coal, and natural gas. These resources are depleting; some sources believe that an energy crisis is to ensue. The energy crisis itself is in question as some scientist don’t believe it will happen and others believe it will. Most scientists do agree however that some form of energies should be replaced as it is dirty and the cost of production of things like coal and oil will increase as it may become harder to find, or harder to mine. Not all energy is considered clean energy, there are multiple problems with burning resources like pollution and its effect on the environment and the areas around the plants or mining operations. The idea of some of the nonrenewable resources depleting imposes a question of how to sustain the current amount of energy needed to run everything that’s dependent upon electricity. Everything is run on electricity from washers and dryers to the lights, the remote-controlled airplane, and computers. Anything that needs to be charged to run is dependent upon some sort of energy. The most common energies currently are the nonrenewable energy. Nonrenewable energy like coal and oil are heavily dependent upon in the current world no matter where in the world. Coal
