Renewable Vs. Non Renewable Energy Resources Essay

Renewable Vs. Non-renewable Energy Resources: Environmental and Economical Advantages and Disadvantages

Imagine a life without washing machines, dryers, refrigerators, computers, televisions, lights, and cars. Imagine a planet so polluted that smog is in the air so bad that one cannot see very far, lakes and streams are poisoned, and land so badly scarred from people trying to find more energy sources. One day this may be a reality if we do not do something to change how we use our energy resources. This may be the case if society keeps using non-renewable energy resources at its current consumption rate. Our saving grace may be the development and use of using renewable energy resources. Renewable sources not only will help our planet stay clean due to little or no pollution, but may also help the economy.

This paper will compare both renewable energy resources and non-renewable energy resources and attempt to show that not only are renewable energy resources better for the environment but also show that they are better for the economy.

Non-renewable Energy Resources
Pollution
One of the problems with non-renewable energy resources is that in order convert them into usable energy requires chemically changing whatever it is to extract the potential energy within. Non-renewable energy resources include wood, oil, gas, and coal. To extract the potential energy contained in these resources it is necessary to burn them, which gives off heat. This heat is converted into energy by using the heat to turn a turbine, which turns the generator, which creates electricity. Using gas in a vehicle the combustion of the gas and air mixture forces a piston, which turns the crankshaft. When burning these materials, heat is generated, and there is a chemical change. This changes the composition of the material. The result of this burning is typically water vapor, ash, and carbon dioxide. Water vapor is not harmful to the environment but carbon dioxide and ash are. Carbon dioxide and ash are pollutants, which cause problems in nature. When too much ash gets in the atmosphere, it can cause smog, which in excess can limit visibility. The carbon dioxide that is produced is harmful to humans and other animals but the main problem with carbon dioxide is it increases what is known as greenhouse gases. Greenhouse gases block the sun’s light from escaping the planet. Without the escaping light, the temperature of the Earth increases. With the temperature increase, weather patterns are changed and polar ice caps can melt.

Economy
Converting these resources into usable energy requires money. Money is required to obtain them, to ship them, and to convert them. This conversion costs money to build the equipment for converting it, money for parts when something breaks, to maintain it, and to clean the equipment. Some parts cost a substantial amount of money to make or in some cases ship in. As one can see, non-renewable energy resources are expensive.

Non-renewable & Renewable resources

A non-renewable resource is a natural resource that cannot be re-made or re-grown at a scale comparable to its consumption. In addition, Nuclear Energy, Coal/Petroleum/Gas (Fossil Fuels), and Coal are all examples of this non-renewable resource. Nuclear energy, uses Uranium to create energy, and is a non-renewable resource because once the Uranium is used, it is gone. Coal, Petroleum, and Natural Gas are considered non-renewable because they cannot be replenished in a short period of time; these are called “Fossil Fuels”.

On the other hand, natural resources that can be replenished in a short period of time are called renewable resources. In addition, Solar, Wind, Water (hydroelectric), Geothermal,…show more content…

Solar cells or photovoltaic cells are a term given to materials that are able to generate electricity by absorbing light. This is done through the photoelectric effect, which was first explained by Einstein in 1905 and won him the Nobel Prize in Physics in 1921 (“How Do Solar Vehicles Work”). Therefore, the electrical energy formed will be applied to the charged batteries and will be used to run the motor which serves as an engine and moves the vehicle in a reverse or forwards motor, and the shaft of the motor will be connected to the rear wheel of the vehicle through chain sprocket (Yogesh Sunil). Hence, the batteries will be initially fully charged and thereafter are charged by panels. This helps in completing the charging & discharging cycle of the batteries, which are very important for proper working of batteries.

Moreover, solar vehicles are the future of the automobile industry as they are highly practical and can be easily manufactured. In addition, the main advantages of a solar vehicle are that they are very economical and pollution less. However, there are some disadvantages of a small speed range and a high initial cost. Other than that, solar vehicles require less maintenance and are very user friendly (Yogesh Sunil). Thereupon, this is known to be the only solution to the increasing in pollution levels from automobiles today.
