Conservation of Energy
In explaining the laws of conservation of energy, energy cannot be destroyed or made. Although, energy can be transformed or transferred from one form to another, for example: The total amount of energy in any system never changes but stays constant over time. Second example: Coal is burned, and then used as thermal energy for heat, next the steam is used for mechanical energy. Energy is never destroyed but changed to forms like thermal energy, gravitational energy, electromagnetic waves, chemical energy and others. (Thus creating the phrase energy cannot be created or destroyed.) There are many advantages of using fossil fuel. One is that fossil fuel help reduce the time it takes time to getting one place to another. For example: Before fossil fuel it would take the average person days to go from one state to another or hours to get travel between cities. Also, in using fossil fuel Power plants could produce enough energy to power their homes, which includes lighting, heat, central air, and cooking. In using oil, gas and coal society as a whole have improved with some side effects. The disadvantage of fossil fuel is the overwhelming carbon dioxide is creating global warming. The toxic fumes create low air quality and when trying to retrieve or transport fossil fuel an environmental disaster may happen. For example: When transporting crude oil many ships have sunk or spilled oil in the ocean. The massive spill caused harm to the plants and animals that inhabit that wide area. Last, countries are relying upon fossil fuel to the point of massive dept. Overall, moving away from fossil fuel will create energy independents, help balance most countries budget, and save the environment for future generations. One more fossil fuel that had to be separate from all the others is nuclear energy. Nuclear power is one of the strongest and low carbon rating sources of energy. Nuclear electricity can generate a high amount of electrical...
