The topic of energy is one that is seen in the news more and more as each day passes. As most Americans can tell you these days, energy is essential for industrial and technological development in this or any other country. However, some believe that certain traditional methods of producing energy, such as burning fossil fuels, are depleting the earth’s limited supply of natural resources and may also be harmful to the environment. They encourage the use of renewable sources of power, such as wind turbines or hydroelectric plants. While some debate humans being the cause of climate change, others believe mankind has barely made a mark on what our planet has to offer us. Conserving energy has nearly become as important an issue as producing…show more content…

The need for coal sparked the American Industrial Revolution and introduced new inventions such as the steam engine.
Petroleum oil, another non-renewable resource, is found beneath the earth’s surface and is collected through oil drilling. The conversion from oil to gasoline allowed for the invention of the automobile. Today, Petroleum is perhaps our most valuable source of fuel. Oil drills and refineries can be found all over the world, and the demand for this fuel has grown so great that it has caused a worldwide crisis.
While some countries depend on oil as a source of fuel, others depend on exporting oil as their primary source of income. “The U.N. Security Council has terminated its authorization of foreign military operations in Libya. And as of tomorrow night, NATO's bombing campaign there will be over. Libyans now have to focus on the future, which includes reconstruction after the devastation of war. Some of the money for that effort may come from the country's oil wealth” (CAN OIL FUEL LIBYA'S RECONSTRUCTION? 1).
The burning of fossil fuels has become a notorious cause of pollution. From contaminants being released into the atmosphere to oceans being devastated from oil spills, the earth’s ecosystem is suffering thanks to years of thoughtless fuel consumption. Excessive utilization of coal and oil for generation of electricity leads to the multiple problems of acid rain, and rising carbon dioxide levels in the atmosphere. There are

In Work and Power we defined work, and began to relate it to energy through the Work-Energy Theorem. Such a relation is not the extent of our understanding of the concept of energy, and we now are able to fully explore this interesting topic, using both what we already know about work and dynamics, along with the introduction of some new concepts.

The conservation of energy is one of the most important concepts in physics. It does not only apply to mechanics, but is a universal truth. This principle becomes the basis of many areas of study, and a full comprehension of the topic is essential for a broad understanding of physics.

We begin our study by differentiating between conservative forces and nonconservative forces, developing two guiding principles and using examples of both kinds of forces. We then go on to develop a new kind of energy: potential energy. An understanding of potential energy, combined with what we already know about kinetic energy will allow us to derive the fundamental concept of the conservation of mechanical energy. We will study various examples of how to apply this principle, and give a limited calculus-based exploration of the topic. By using energetics instead of kinematics or dynamics, we can greatly simplify many physical problems, and also gain a broader understanding of mechanics within the larger principle of energy.
