Some common alternative energies are solar, wind, hydroelectric, geothermal, hydrogen, and biofuels. The U.S. should use those alternative energies over fossil fuels, Petroleum (oil), coal, and natural gas. We currently have ways to store and use these types of energies but the ways we have are not the most effective. That is why the U.S. should fund the research of better ways to harvest and use these alternative energies. All the alternative energies proposed before are renewable.
This essay has attempted to evaluate the potential renewable energy both in terms of sustainable development and reducible global warming. Renewable energy such as biofuel and wind energy can be seen as a safe, reliable and cost effective alternative to using fossil fuels for energy security. However the development of green energy has drawbacks so funds for research and develop for chance from lab-scale products into commercial products should be provided and these fuels will become increasingly expensive to use. Clearly more could be done to produce carbon-free energy and more efficient and reduced environmental impacts. Also awareness of the advantages of renewable energy has been steadily growing and it is expected that the share of renewable energy in the total generation capacity will increase in future.
Whereas fossil fuels are limited since they come from specific materials years ago, biofuels are renewable (since you can always produce more if it runs out) and can be manufactured from a variety of materials such as: crop waste, manure and other byproducts. This takes recycling to a new constructive level. Likewise, the amount of carbon emissions will also decrease drastically since when biofuels are used, they produce significantly less carbon and fewer toxins. This also makes them a safer alternative in order to preserve atmospheric quality and lower air pollution. In terms of economic stimulation, the economy will find stability as when using biofuels you can disregard afore mentioned fluctuating oil prices due to change in demand.
When the new hydrogen fuel cell plan is looked at closely it actually uses oil that could be set aside. I feel that Bush’s plan for funding fuel cell research will not solve many of today’s problem regarding oil problems in our country because it could be more efficient and have more immediate effects. Although Bush’s plan could someday make a huge difference in the amount of oil used in the US, there is no way of knowing when any changes will be seen. I feel that something needs to be done to change our oil consumption as soon as possible. A major change would be seen very soon if President Clinton’s plan were to continue being funded.
Common types of fossil fuels are coal, oil and natural gases. An energy source that conserves the environment and is healthy to people is the top concern. People today are too dependable upon destructive fossil fuels for energy, which is why our attention should turn to renewable energy to conserve our natural resources. Furnishes of fossil fuels will eventually disappear and then we will loose our main source of energy for things that we do everyday. This is why the importance of finding other sources of energy is so significant.
Biofuels Biofuels were the first liquid fuel, which include oils, animal fats, and ethanol from crops (Kovarik). They use alternative sources of materials to create fuels, which can be a key feature for our future. Our economy uses some of the dirtiest and most harmful materials to create our fuels and everyday uses, which is slowly hurting our environment. The use of biofuels can save our money spendings, and have more of what we need to survive. People say that biofuels are not healthy for our environment, but in reality they are stronger and more efficient.
“The U.S. cannot afford to invest and lock itself into many more decades of reliance on the dirty and unstainable sources of energy of the past” (Yang n.p.). Renewable energy such as solar, wind and hydro power do not give off pollution like fossil fuels do. If we were to switch to renewable energy we would eventually stop global warming and live healthier lives. “Clean-tech is a fast growing global industry that holds the potential to fix our current climate and other environmental challenges”(Yang n.p.). Unfortunately the renewable energy technology is not as affordable as fossil fuel technology, which is one of the reasons why we are using fossil fuels.

Another reason we need to find a new source of energy is because the use of fossil fuels has been proven to cause harm to the earth and its environment. At the moment ninety-eight percent of the U.S.’s energy consumption is fueled by fossil fuels. In addition, with safer and cleaner energy sources we will be able to ensure a cleaner planet for future generations to come. What exactly are non-renewable resources? Non-renewable resources are something that can be used up over a period of time.
Renewable energy may give the impression of being expensive compared to fossil fuels; however, renewable energy is much more beneficial to the environment. Renewable energy sources have a miniscule impact on the environment due to the fact that it produces little to none pollutants and gases (Solar Schools). The harmful pollutants produced by fossil fuel usage is responsible for many health issues that affect thousands, possibly millions of people in America. To continue the use of fossil fuels is analogous to digging our own graves; renewable energies would save us from the harmful effects of fossil fuels, “Replacing fossil fuels with renewable energy has been found to reduce premature mortality
