October 4‚ 2010 This topic of this research paper is to discuss why we need to switch to alternative energy sources. Alternative energy sources are readily available‚ environmentally friendly‚ and cost effective. Unlike fossil fuels‚ there is an unlimited amount of resources‚ and a lot less pollution. Energy demands of our population are steadily rising. In the 1960’s energy consumption had increased 51 percent‚ compared to 36 percent in the 1950’s (Hakes‚ pg 17). The

it is gone. Instead of using fossil fuels and having them burn to waste use solar energy and use what the sun gives us every day. Solar energy is an effective alternative source because there is very little pollution‚ they cut down on fossil fuels and are cost effective. Solar panels give off no pollution‚ radioactive waste or carbon dioxide‚ the only pollution is from the manufacturing‚ and installing which is no were close to the pollution of nuclear‚ fossil fuels‚ or wind energy. Unlike wind

other hand non-renewable resources cannot be restored after being used once it’s used. Additionally non-renewable resources are in limited supply and be used once. Examples of these resources are Coal‚oil and natural Gasses‚ they are known to be fossil fuels; They take millions of years to form. They have to be mined or drilled from deposits deep within the earth. And the Reason we should save them is because if we don’t what will we have left for example if we use too much paper we will end up cutting

the use of fossil fuel in history‚ people used to use coal as a main source energy. After the second half of the industrial revolution‚ people switched from coal to oil‚ and then natural gas. Nowadays‚ coal‚ oil‚ and natural gas are the three main energy resources. The exploitation rate never catches up to the consumer rate. There are three main reasons. First of all‚ as the population increases‚ more fossil fuels are in demand. Secondly‚ most developing countries use more fossil fuels in order to

States. Renewable energy is any energy that its source is naturally replenished‚ which is solar‚ wind‚ geothermal or hydroelectric action. There’s another type of source called fossil fuel which is coal‚ oil‚ or gas there are nonrenewable source. Fossil fuels provide energy at a lower cost than renewable energy‚ but fossil fuel is the largest source of carbon dioxide which allows radiative forcing and contributes for global warming and the fear that it can all run out.

demand for fossil fuels growing through out the world‚ there is with out a doubt a lack of supply for this demand. The United States is the world’s highest consumer of fossil fuels because of the amount of Automobiles that we have on the roads every day. This is not one of the statistics that a country should be proud of being at the top of. Since the United States is the leader of the consumption of these fossil fuels‚ the government is making an effort to look for alternative fuels that we can

and at the same time‚ the declining availability of fossil fuel‚ many countries seek cheap‚ alternative ways to produce electricity for their people. As nuclear energy is cheap because of the large amount of uranium reserve on Earth and that it is also able to produce large amount of electricity‚ it has become the most likely solution to solving this issue. 3. The significance of the issue Nuclear energy has the potential to succeed fossil fuels as the main source of generating electricity. This

Coal is widely used because it’s easily obtained‚ there’s lots of it‚ it’s well distributed throughout the world‚ and it has a high energy content.” Coal usually has a negative impact on environment‚ mining can damage ground and surface waters and when coal burns as the fuel it releases carbon dioxide.
