This has led to pollution playing a significant role in the mass support of a certain fuel. By far, every fossil fuel is highly opposed due to the pollution, but one can also conclude that right now, energy generation from pollution-free sources (e.g. solar) are mostly in their pilot stages, and it will take time and deeper research to develop them to a commercial level. Since the industrial revolution, the greenhouse gases emission has increased exponentially. The environment has been on the receiving end for the last half century. EPA expects an increase in the concentration of greenhouse gases by the end of 21st century. An increase in the greenhouse gas concentration will not only raise the average temperature across the globe, but will also affect the precipitation patterns. U.S. is expected to experience an increase of anywhere from 4-11 ¬0F. North America will experience greater precipitation during winter, spring whereas Southern Areas, especially the west, will become drier, and the list goes on (Par. 1-5). As one can see, huge changes in the climate are imminent. This outcry is not only of the middle-class citizens of the world. Many celebrities have taken it to social media to raise the awareness of the phenomena “Global Warming”. Bill Gates, the founder of Microsoft, once said, “Climate change is a terrible problem, and it absolutely needs to be solved. It deserves to be a huge priority.” (Brainy Quotes)
In the present, it is not possible to live without fossil fuels. We depend on it. Our modes of transportation depend on it. Humans and fossil fuels are entangled in a complex web, but one cannot take combustion for granted since it pollutes the environment. Hence, in order to understand what fuel would be suited for the U.S. economy, one needs to understand the three major energy fuels combusted daily in the United States, namely coal, oil, and nuclear
