Conventional Transportation Fuels

The U.S obtains more than 84% of its energy from fossil fuels including oil, coal and natural gas. This is because people rely on it to heat their homes, power industries, run vehicles, manufacturing, and provision of electricity. It is apparent that the country’s transportation industry highly depends on conventional petroleum oil, which is responsible for global warming, thus threatening economic opulence and national security. Apart from that, increasing consumption of fossil fuels have elevated health problems in the state, destroyed wild places, and polluted the environment. After conducting Environmental Impact Assessment, projections showed that the world energy consumption would increase by more than 56% between 2010 and 2040. However, fossil fuels will cater for more than 80% of the total energy used in 2040. Sadly, it will be a trajectory to alter the world’s climate, as well as, weaken the global security environment. Importantly, the rate at which the US relies on fossil fuels needs to reduce since it has adverse effects on the planet’s supplies. The society needs to realize that fossil fuels are nonrenewable, thus taking millions of years to form (Huebner, 2003). Notably, the country can reduce dependency on fossil fuels by practicing energy conservation and efficiency,

According to statistical data “Almost all (95%) of the world's transportation energy comes from petroleum-based fuels, largely gasoline and diesel.” (United States Environmental Protection Agency, n.d.).

Fossil fuels—coal, petroleum (oil), and natural gas — are concentrated organic compounds found in the Earth’s crust. They are created from the remains of plants and animals that lived millions of years ago in the form of concentrated biomass. According to the US Energy Information Administration (EIA), fossil fuels meet 81 percent of U.S. energy demand.

Other research has shown that production of these alternative fuels has generated great deal amount of emissions, which does aid in global warming, while other research shows that long use of these fuels has shown to dramatically reduce greenhouse emissions which also lower the rising temperature of global

The automobile industry is constantly being revolutionized through new technology resulting in a fuel concept for consumer vehicles. Although these new alternative fuels are a break-through for the automobile industry, where do they stand in comparison to our conventional vehicles? This paper will address this issue by asking: What are the environmental and economic benefits and disadvantages of alternative-fueled cars compared to conventional cars?

Engines run on petroleum. Petroleum is used in many products such as plastics, ink paint, shoe polish, nylons, roof shingles, novelty candy, cosmetics, candles, vaseline, bug biller, ammonia, tires, asphalt, crayons, paper, cups, and wax paper. Although petroleum may be useful in many applications, the best used for petroleum is diesel fuel for many reasons. One reason diesel fuel is the best and most efficient use for petroleum is that diesel fuel contains about 14% more energy by volume than gasoline. This makes diesel fuel the most efficient fuel for use in automobiles and trucks. Diesel fuel is especially the most efficient fuel for use in towing all types of vehicles for many reasons. One reason diesel engines are better for towing is that they have more low end torque because of their higher compression ratios. A diesel engine 's compression ratio is between 15:1 and 23:1 compared to the compression ratio of a gasoline engine which is 10:1 to 12:1 but if the compression ratio is raised from 10:1 to 15:1, the thermal efficiency will improve by roughly nine percent. Diesel engines also deliver twenty-five to thirty percent better fuel economy than similar performing gasoline engines. When compared to a 4.0 liter gasoline engine, the Cummin’s 4BT3.9 diesel engine is much more fuel efficient engine.

Oil is a non-renewable fossil fuel found all around the globe. According to Energy.gov, “Oil reserves are found all over the world... The top oil producing countries are Saudi Arabia, Russia, the United States, Iran, and China.” (Energy in the 21st Century, 2013). According to an article from Adventures in Energy, there are three ways oils is extracted from the Earth (Extracting Oil and Natural Gas, 2008). The three way oil is extracted are: Primary Recovery, Secondary Recovery and Enhanced Recovery (Extracting Oil and Natural Gas, 2008). Each type of recovery is a form of drilling for the oil. Enhanced recovery is used to extract the large amounts of oil left behind by the primary and secondary recoveries (Extracting Oil and Natural Gas, 2008). Some recoveries use steam, water, chemical injections and other methods to extract the oil from the Earth (Extracting Oil and Natural Gas, 2008). When processed oil is used for many household items and everyday motor activities. The most commonly known source of oil use is fuel, “gasoline. It is used to fuel most cars in the United States” (Energy in the 21st Century, 2013). Oil other uses include, “heating oil, diesel fuel, jet fuel, and propane… It can also be used to make many common household products, including crayons,

Fuel alternatives for the future are very important because, we need resources for life. We won’t have fossil fuels forever. It is important to start now. If we did not have any fuel alternatives how would the world be?

There are many different types of alternate fuels for cars at our disposal, such as Ethanol, Natural Gas, Electricity, and Hydrogen Fuels. We can use these fuels instead of normal gasoline fuels that pollute our air and contribute to destroying our environment. Many of these alternative fuels may be less convenient to use, because they are less accessible. However, if people decide to use these fuels then they can make our world a green friendly world. There this a ton of upside to using alternative fuels, according to Larry West’s article on the top eight alternative fuels, as they can help nations become more energy independent. In addition, there are several downsides or challenges associated with alternative fuels for cars, such as

As we all know the energy we use form fossil fuel is nonrenewable, and it damages our environment badly. The most energy is used in the industrials (31%), the second is used in transportation (28%), the third is used in residential (22%), and the last is used in commercial (19%). We also know that the more we use fossil fuel, the more greenhouse gas effect to our earth and killing our atmosphere by trap the gases and it make our earth getting warmer and warmer. In this paper will go deep more into the second big use energy which is transportation and how they are going to use the new energy to keep the environment cleaner. However, our world has created a lot of renewable energy such as energy from solar, wind, geothermal, hydroelectric, biomass, and nuclear. In fact, the new Bioenergy, which uses household garbage, including food waste, for its fuel could be a great idea to save our natural energies, also less emission on the greenhouse effect, save money instead of wasting it.

Studies show that there is an increasing interest in alternative fuels for use in vehicles (cars and trucks). Most substitute energies are sourced from reusable products. Some of these alternative fuel products are produced domestically, and this reduces the United States dependence on imported fuel (Norman, 2007). The augmenting attention in substitute energies is motivated by numerous factors. To begin with, substitute energies result to reduced vehicle emissions; such emissions produced in the conformist vestige-energy result to orangery gases and haze. These effluent products have led to global concerns since they accelerate global warming and increasing air pollution.

Diesel (the dominant fuel) has grown in its demand in several countries. Yet, to counteract the increased rate at which diesel is sold, we are forced to seek alternative ways to provide effective and sustainable qualitative fuels. After researching alternative fuels based on the knowledge of how diesel works in an engine, it was found that diesohols (blend of diesel and alcohol) were proven an easy understudy to pure diesel. Without any major modification in an engine, diesohols have the ability to power a car, for example, like in any normal circumstance (Chemical and Pharmaceutical Sciences, 2015).

Alternative sources of energy are essential because the oil has approximately a hundred years of oil consumption before it becomes extinct and the oil has more effects in the pollution of the environment (Efstathios 6). Other energy sources are not used because they have not made their way to the mainstream. According to Efstathios (2012) that alternative energy sources should be implemented as soon, or people will live on a borrowed time, and also to counter-balance the increasing demand of energy globally. The strongest point for alternative energy use is the extinction of oil, which should be replaced by other sources of energy. Extinction of oil can lead to severe effects (borrowed time) because many activities depend on oil availability. Geological and climate-specific alternative energy solutions are not as available, inexpensive, efficient and reliable like oil. Hydrogen is close to oil because it is also used by cars and has no side effects. The other energy sources depend on climate, hence making them unreliable (Thomas 939).

For decades a certain problem has been slowly growing day-by-day. Today the problem has been more prevalent than ever before. In recent years the current energy usage, which is fossil fuels, is not sustainable and carries negative effects to the environment. However nothing is perfect, even renewable energy has its fair share of disadvantages. Can alternative (reusable) energy sources such as nuclear, hydrogen, biofuels or solar energy meet the energy demands needed by humans to carry out their everyday tasks such as electricity, commuting, and so on better than fossil fuels such as coal and oil which creates a mast amount of energy today. Fossil fuels are considered to be unsustainable, environmentally destructive, inefficient, and the primary contributor to global warming. It is estimated that about 88 percent of global energy is produced by burning fossil fuels5. Additionally, only 12 percent of global energy is produced by clean alternative energy sources5. It is time for individuals to think whether alternative energy can efficiently replace fossil fuels.

Global warming is one of the most critical issues faced by both humans and animals. The increase of earth’s temperature leads to climate change, eventually, making life much harder for people in developing countries and causing animals to become extinct. For decades this problem has been slowly growing day-by-day. In recent years, dependency on fossil fuels has increased immensely, to the point where it fuels daily activities. However, it is important to take into consideration that while fossil fuels provide tremendous amounts of energy, there are several adverse effects and disadvantages to using it as a source of fuel. As an alternative to fossil fuels, renewable sources such as nuclear, hydrogen, or solar energy and biofuels can be used to meet energy demands. Fossil fuels are considered to be unsustainable, environmentally destructive, inefficient, and the primary contributor of global warming. It is estimated that about eighty eight percent of global energy is produced by burning fossil fuels1. Additionally, only twelve percent of global energy is produced by alternative energy sources1. It is time for individuals to think whether alternative energy resources can efficiently replace fossil fuels.
