Oil: a dwindling natural resource
There are lots of problems with the energy resources that we use. Coal is unclean, nuclear is dangerous, and there simply isn't enough wind energy. Oil, although it is topped by coal in the amount of energy it produces in the U.S., is still one of the leading factors in our global economy. In fact, if oil were to disappear right now, entire countries around the world would collapse, because of the electricity, cars, and economies, that are driven by oil. Although we depend on it, it is not a renewable resource, and what we have is what we have. Before we run out, we need to find a way to depend less on it, and depend more on other, renewable sources of energy such as wind, solar, and hydroelectric. Not only are these renewable, but they are also cleaner, and all around better for the environment. Changing energy sources is one step of many to right the damage we have done to this Earth, and help insure that our countries can continue in a world of technology and innovation.
