Renewable Energy: The Way of The Future

By Robert Hudson

Pollution and global warming are at the forefront of every ecologist and environmentalist minds these days. In addition, many nations across the globe have taken necessary steps in order to reduce their own carbon footprint on this planet. One of those possible measures is using a cleaner source of energy supply, rather than relying on fossil fuels such as oil or natural gas. These forms to energy are called renewable because unlike fossil fuels, the have an endless supply. Some of those include solar energy, wind energy, hydro-electrical energy, and finally nuclear energy. These are just some cleaner ways of energy production that we can use in order to reduce our pollution. In this paper I will discuss the following options in greater detail. I will point out what exactly each one is, the process of production into useable energy, as well as the pros and cons to each energy source.
To begin, we will take a look at solar energy. Solar energy is exactly what is it, energy that comes from the sun. Solar energy is a process in which solar rays or the heat that the sun gives off is collected by solar panels made up off cells called photovoltaic (Toothman). These cells are made of silicon in its crystalline form and other semi conductive materials combined with it. When the sun light hits the silicon, the heat causes the electrons in the material to start moving freely. Then an electric field causes these electrons to move in a form of a current. By conducting that current we can siphon the electricity off into batteries, and store the energy made.
There several advantages and disadvantages to this form of renewable energy. Let’s start with the advantages. The first is that no pollution is created from this form of production of energy. Another is this process requires to type of fuel to operate, and since there is no fuel required, once your install it, there are no reoccurring costs since solar radiation is free. Another great benefit is that the panels can be made to fit any size, making them convenient to install anywhere for a variety of purposes. Furthermore more panels can be added at any time. Lastly a solar energy system can operate entirely self-sufficiently, not requiring a connection to a power or gas grid at all. Systems can therefore be installed in inaccessible locations, making it more practical and cost-effective than the supply of utility electricity (Solar power –,"").
In contrast, there are some disadvantages to solar energy. The first being the initial cost of the installment. It’s very expensive to build and install a solar panel in residential urban areas, due to the semi conductive materials used in the cell itself. As well, it takes a large about of space needed by the panels for adequate energy absorption. Another major downfall to solar panels is that they are affected by cloud and air pollution. So weather is always a...

Exploring the Possibilities of Renewable Energy

3668 words - 15 pages might seem like a lot now, but as the world's population increases, this number will be sure to follow. To avoid a possibly enormous energy shortage, governments should focus on changing over to renewable energy gradually while fossil fuel sources are still available. The only factor that stands in the way of research and implementation is politics. According to McGown & Bockris (1980), "To attain a new and more hopeful chance for the future

The Environmental Impact of Renewable Energy

840 words - 3 pages The amazing thing about renewable energy resources is that they do not deplete. These energy resources include energies such as hydroelectric energy, solar energy, wind energy, and geothermal energy. The major advantage of using these resources is that the environmental impact is extremely low when compared to the use of fossil fuels and other energy processes. One of the most used renewable energy sources is hydroelectric power. When you

Not only is it just creating jobs, but it creates them for all types of education and skill levels. The reality of global climate change due to fossil fuels and rising carbon emissions makes it a necessity that the U.S. economy dramatically cut its consumption of traditional energy sources. The primary source of carbon

Solar Energy: The Ultimate Renewable Energy Resource

2890 words - 12 pages air between the two walls is heated and moves through the vents into the room to form a convection current. At night, the heat stored in the thermal block is released, therefore maintaining the room temperature. A passively heated home uses about the 60-75% of the solar energy hitting its walls and windows. The Center for Renewable Resources estimates that in almost any climate, a well-designed passive solar home can reduce energy bills
