Biofuels : Alternative Sources Of Energy Essay

Switching from the expensive oil to alternative fuels has moved from a dream to reality. Today, there are dozens of alternatives to oil that are currently available us to be used. One alternative to oil that is being used more today is ethanol. Derived from plant materials, ethanol can be a cheaper, cleaner alternative to the gasoline that our vehicles run off. When going to gas pumps, one will notice that much of the gasoline is up to 10 percent of ethanol. According to our text, most ethanol in the U.S. is made from corn, yet ethanol can be made from any biomes-- including garbage. (Turk & Bensel, 2011)

     "We need more stringent regulations on car emissions... Let's add MTBE to the fuel- that will reduce pollution... If people would just stop driving so much, pollution wouldn't be so bad..." People have long recognized the problems with the gasoline we used now.  We have tried everything from putting regulations on emissions, to putting additives in the gasoline (only to discover later that MTBE got into the groundwater), to campaigns to get people off the road.  However, more and more cars are on the roads as the population increases, and people are not going to stop driving.  Additives are as likely to cause problems as they are to prevent them.  Just changing the

What if there was an up and coming fuel that has the properties of normal oil, but its side effects were not nearly as bad? Would you support it? Well there is such a thing. It has been around for a few years, but only in the near future does it have the potential to do good on a worldwide scale. This innovation is called algae biofuel. Algae biofuel is a fuel just like gasoline or diesel, but instead of being mined from the ground, causing irreparable damage, it grows in a pond and actually has positive side effects on the environment. Algae Biomass Organization states, “Algae-derived biofuel can reduce life cycle CO2 emissions by 50 to 70 percent compared to petroleum fuels.” Algae biofuel could be one of the solutions to our polluted atmosphere.

Biofuels are fuels that are produced by a biological process. A biofuel is a mixture of organic substances that are used as fuel in an internal combustion engine. Derivative of biomass, organic matter originated in a biological process, spontaneous or provoked, usable as an energy source.

For over forty years now, scientists and researchers have been tirelessly searching for an alternative to fossil fuels. Biofuels have become an interesting contender in the search for the replacement of the non-renewable energy source. Biofuels have been used throughout history for over thousands of years. There is a large debate over biofuels and its true impact on the environment. Those involved in the discussion debating whether biofuels have any real overwhelming benefits compared to fossil fuels could argue for its usage. According to recent research performed by the University of Michigan, biofuels may not be the best alternative for fossil fuels. Regardless of its impact on the environment, biofuels are becoming more popular particularly when the price of oil rises.

Alternative energy versus fossil fuels is a very controversial issue surrounding America today. The issue is so controversial for many reasons, such as our economic dependence on fossil fuels and the possibility of global warming due to the burning of these fossil fuels we are so dependent on. Where one argument seems to succeed in persuading the reader one way, another rebuttal can be made that will neutralize the arguments before it. If the United States become more alternative energy dependent, it could destroy thousands of jobs, or it could save the US’s economy.

Carbon dioxide, the chief byproduct of fossil fuel combustion, is a potent greenhouse gas that remains in the atmosphere indefinitely. In the U.S., the burning of coal for electricity pumps more than 2.4 billion metric tons of carbon dioxide into the atmosphere every year, according to the Energy Information Administration. People ask what about the cars? How do they affect the environment? The average American passenger car spits out 11,450 pounds of carbon dioxide every year. There are 246 million cars in the U.S. To cut down on carbon dioxide emissions, governments, car manufacturers and utility companies have been seriously pursuing alternative energy sources. Among the leading contenders are biofuels - renewable, clean-burning fuels made from plant- and animal-based source materials like corn, soybeans, discarded vegetable oil or animal fat. We hear a lot about biofuels and fossil fuels in the news, but sometimes the two terms can get tangled in our minds. Are fossil fuels really made from fossils? Can a regular car fill up on biofuels? Are there any clean-burning fossil fuels, like natural gas?.

Well we all know that the energy system is very unstable because the total energy available on the earth is limited, and man has exploited all the conventional technologies to fulfill his needs. By the use of these conventional technologies, the world also has a disability, with problems such as global warming. Consumption of energy by man increased gradually as his wants also increase. The conventional energy resources mainly include fossil fuels, but research shows that this fuel source will be depleted completely in approximately 20-25 years. This could cause major setbacks around the world. As a result, we need an alternative source of fuel that could keep the world running on its wheel. One possibility is ethanol. Chemically extract

Polar bears are the most known animals for the impacts of climate change on species. Global warming has been most prominent in the Arctic, and this trend is expected to continue. Their dependence on sea ice makes them highly vulnerable to a changing climate. Polar bears greatly rely on the sea ice environment for traveling, hunting, mating, resting, and in some areas, maternal dens (WWF). Specifically, they depend heavily on sea ice-dependent prey such as seals. Additionally, their long generation time and low reproductive rate may limit their ability to adapt to changes in the environment. Every time people breathe or burn something, oxygen in the air is converted to carbon dioxide. The carbon dioxide is used by plants to breathe and is converted back to oxygen, creating a cycle. If there is an increase in oxygen burning, for example, burning a lot of coal or oil to generate electricity or run cars, and cut down trees, the amount of carbon dioxide in the air is increased. This makes the air thicker and warms up the earth. The amount of warming is only a few degrees but it is enough to disturb the fragile balance of nature, which in turn will melt the polar ice, raise sea levels, cause violent hurricanes and endanger species such as polar bears. The polar bears are just one example of endangered animals because of the high demand of human need for energy which is acquired by burning fossil fuels.

In the world of global warming, all kinds of pollution and fuel shortages going on, renewable and clean/ green energy is increasingly the ideal solution of energy related problems we have to solve one way or another. Biofuel is one of the mainstream and highly supported solutions nowadays, an idea to make renewable fuel by living organisms such as fiber, corn, vegetable oil or sugar cane. Unlike nonrenewable fossil fuels over extracted by people causing various environmental problems like generating a considerable amount greenhouse gas, current technology already lets renewable fuel like biofuels to shrink a certain amount of greenhouse gas production, making it a more ‘clean’ source of energy.

Fossil fuels are an important part of life. When you turn on the lights, watch TV, or take a shower, the electricity that you are using is being generated by fossil fuels. The three types of fossil fuels are coal, crude oil, and natural gas. They all take millions of years to form, so they are considered to be “non-renewable”- eventually, the fossil fuels will all be used up. One dangerous biological effect of using fossil fuels is ocean acidification. Extracting and transporting fossil fuels can also be very dangerous. Environmentally damaging accidents such as groundwater contamination, land subsidence, and oil spills occur frequently. Global warming is another possible environmental effect. Fossil fuels have a crucial role in modern

Many including Rothkopf, Grunwalf, and Ruiz-Marrero claim that biofuel is not the solution but rather will become a problem. They claim that if biofuel was produced in large quantity then agriculture would convert from food to fuel. According to the World Bank, over seventy five percent of the rises in food prices is directly caused by biofuel. Indonesia is the leading producer of palm oil, a major biofuel. In order to increase productivity, the people destroyed thousands of trees to plant palm tree. The destruction led to an increase in carbon production. Indonesia moved from the 21st most carbon producer to the third. Another major producer of biofuel is Brazil. If Brazilian farmers were to deforest the Amazon rainforest, it could cause a fifty percent increase in global warming. Through the world, deforestation accounts for over twenty percent of carbon emission. A gallon of biofuel requires the same amount of grain as a person would eat in a year. The switch from food to fuel would cause a worldwide food shortage and an increase in world hunger.

Finding energy sources is an issue that polarizes scientists, politicians and citizens alike. The most critical points of this debate are at fossil fuels and renewable energy. Energy efficiency is arguably the most dire concern facing the planet, because it significantly impacts all areas of everyday life. Common ground can be found in this controversy because both parties do agree that humans have a responsibility to future generations. That responsibility is to preserve the resources of the Earth, while offering this generation energy that is affordable and accessible.

For the past three decades Oil dominates the agenda of political discussion. With scares over price volatility, sizes of reserves, international imports and least of which are the environmental impacts due to carbon dioxide and other emissions. Various speculations and educated guesses place our total depletion of crude oil within the next 50 years and there is a general consensus between environmentalists that we steer toward a hydrogen transportation system given the projected work and nonexistent carbon dioxide emissions (Environmental Technologies class lecture, Santa Clara University). However many barriers stand in the way of attaining such a goal, most of which pertaining

America needs to free itself from oil dependency. Every day billions of dollars are spent on resourcing oil from other countries. The United States consumes around 20 million barrels of oil every day. In the 1970’s when the energy crisis happened, oil prices skyrocketed and the supply of oil ceased, efforts shifted to find alternative sources of power. Although many people believe alternative fuels are being researched and developed for environmental reasons such as reducing our carbon emissions, they are actually becoming integrated into our lives from an economic standpoint. Hydrogen, Electric, and Bio-fueled cars are all excellent sources of
