Recommended: What advantages do fossil fuels have over renewable energy

As of 2008 the United States only 8.8% of the power they use is renewable, 71.9% fossil fuels, and 19.2% nuclear (Heinrichs, 18). Renewable energy sources are energy sources that can continuously be replenished without producing pollution. Right now the world depends on fossil fuels for energy but they are running out of them and need to find an alternative energy source. As more people are being born the demand for energy is rising and we need different ways to get it. Without a doubt renewable energy sources are better than fossil fuels because they do the same thing but in a cleaner and renewable way, but what you use the energy for always depends on how you get that energy to see if it’s worth it (Konrad). Although many people see renewable energy sources as positive alternatives, they do not know what negative effects they can have.
The sun warms up the planet but people can also use that to warm up their own house. Not only does the sun help with heating but it can also help with other renewable energy sources. The sun is considered the most powerful energy source because it makes wind, is part of the water cycle by evaporating water, and it helps plants grow (West). Solar power uses the dark blue, tile looking machines known as photovoltaic devices that gather the energy and convert it into energy (Wieman). Since the sun does not always shine on the same spot, people need to choose the location of these devices wisely. When they have the device in the right position then they can start gathering power. Solar power collects solar energy from the sun, then “converts that into sugar and starches which then break down to create chemical energy” (Heinrichs, 12). This seems as a wonderful but not many people realize how...

...ter, the United Kingdom National Grid Company planned to build a wind turbine farm. Since a wind turbine farm takes so much surface area, many residents protested against it so they would not lose their land (Pidgeon and Demski 42). Ultimately renewable energy sources can prove to be troublesome. Not only do they affect the land but these renewable energy sources can also change the weather around that area.
Even though many people see renewable energy sources as the future of gathering electricity, they do not know whether renewable sources are as efficient as people think. As a thriving species, humans need to find more ways to live. One of these ways includes the ability to gather energy that they need to survive. Renewable energy is a rather new concept and not much people know about it but finding ways to harvest this energy is also difficult (Konrad).

  • How Can the United States Lessen its Dependence on Fossil Fuels?

    1536 Words  | 4 Pages

    Semantically fossil fuels are a renewable source of energy, however given that it takes millions of years for the organic materials to be broken down and converted, it is wholly unrealistic to consider them as renewable. As the demand for fossil fuels increases and source diminish faster than they are replentished, the United States must work towards a renewable energy independent state using truly renable sources, both technically and in practice. With changes in the home, as consumers in buying goods and with alternative fuel sources backed by public trust and governmental involvement, the United States could drastically lessen its dependence on fossil fuels, foreign and domestic.

    “Last year, China became the largest provider of wind energy in the world, with 41,800 megawatts of electricity capacity. The United States, with about 40,000 megawatts, fell to second.” China has been known for trying to use all renewable energies instead of non-renewable energies. United states being second is great but 40,000 megawatts aren’t very much considering how many people there is in the United States. “Local officials in Wisconsin, as in many other states, have the authority to determine how close a wind turbine may be built to a house or property line. This has led to a conflicting set of rules, with residents worried that wind farms are encroaching on farms and subdivisions.” If you think about it, waking up every day and seeing big turbines in your backyard and may be blocking your view, that would suck and you would probably be upset. They made regulations for how far away turbines should be from people’s

    The year is 2200. The world is going through a fossil fuel shortage. Oil reserves are almost completely consumed and it is becoming impossible to find new fossil fuel sources. Not prepared for this event to occur, The United States, has no alternative options. As a result of the oil shortage, the standard of living deteriorates. Heat in homes, supermarkets full of food, and transportation, all basic necessities taken for granted, will be depleted because fossil fuels are used to power almost everything. The key to the prevention of this future is renewable energy. Unfortunately the support for the use of renewable energy is weak and ineffective. Unless the US puts forth effort to research and promote the use of renewable energy to consumers, conversion from fossil fuels to renewable energy will no longer be an option.

    Energy is the basic necessity of daily life. Nowadays, dependence on fossil fuels for energy needs becoming lower in numerous countries due to the potential of renewable energy to supply sustainable energy to the huge populations in many developing countries who are short of clean and continues energy. Generally, renewable energy can be defined as energy that is derived from natural resources which are constantly replenished and theoretically inexhaustible. Fossil fuels on the other hand can be described as energy that cannot be renewed and will eventually diminish. Thus, in many developing countries renewable energy is the alternative energy to replace non-renewable energy or commonly known as fossil fuels. In addition, according to Sorensen (2004), there is a greater demand for renewable energy sources nowadays due to the uncertainty of fuel price rise in living expenses. Commonly, there are many types of renewable energy available in our world such as wind power, biomass energy, solar energy, hydroelectric power and geothermal energy. However, the main three example of renewable energy are hydroelectric power, solar and biomass energy (Refer to Figure 1 in Appendix 1).

    In the debate of traditional energy vs. renewable energy the clear winner is renewable energy. Renewable energy is vastly superior over traditional energy because it decreases dependence on foreign resources, produces no emissions, and is not limited in quantity. Opponents of renewable energy are likely to argue that this is not the case and that instead, traditional energy is better because it creates job growth, is reliable during all hours and climates, and comes with a lower cost. These advantages however are either misconstrued or hardly outweigh the long-term positive benefits of renewable energy.

    Wind power is another form of solar power. Wind isn’t only a clean fuel source, but it is one of the most inexpensive e alternative sources of energy. Just as long wind continues to blow and the sun shines then wind power can produce energy to send to many different areas. There aren’t many locations that have continuous wind. And because of that the widespread development of wind power isn’t as great as it could be. Although there are more advantages than disadvantages when it comes to this energy source, the disadvantages should be taken just as seriously. Wind power can harm animals, there was a study that stated birds were coming in contact with turbines and dying. For many people the noise from the turbines is unbearable, and that’s something else that should be taken into
