Bio Fuels Are Better Than Fossil Fuels

1611 words - 6 pages

Fossil fuel plays leading role in upsetting environmental, economical and climate protection. Our earth is at catastrophic risk by the exploitation of fossil fuels. Therefore, pressure is on to find viable alternatives for energy to bring a stable, safe and clean revolution. In that case, bio-fuels make an attractive alternative for energy than fossil fuels. Various provocative questions need discussion that what are the attractive differences between both the fuels? Why fossil fuel dependence is to be actually minimized? What is the scope of bio-fuel for a safer world? How will bio-fuel benefit economically? Above all, It will be conferred that why bio-fuels are better than fossil fuels.
There are two foremost competitors for energy resources in this world. Archaeologically, Fossil fuels are the remains of prehistoric plants and animals deep inside the earth and are the derivative of hydrocarbons, which is composed of hydrogen and carbon molecules. These exist in the form of coal, oil and natural gas. Another leading contender is bio-fuel, which is the fuel that is obtained from biological sources such as agricultural crops, including corns, soy; algae and biological wastes. Mainly it contains biodiesel, ethanol and butanol.
Ever since, fossil fuels are an overriding source for energy to drive regular tasks and operations. The expansion in human activity most significantly the burning of fossil fuel to meet the energy demands emits tons of carbon dioxide gas in the air, which is one of the largest greenhouse gases. They form a blanket that bundles up the heat in our atmosphere and warm the planet contributing to global warming and air pollution. Due to which, earth's average temperature has risen by 1.4°F over the past years, and is anticipated to increase another 2 to 11.5°F over the next century. Statistically in 2011, carbon gas was accounted for about 84% out of all U.S. greenhouse gas production from human activities. This burning carbon has overloaded our earth with detrimental effects, including severe storm, drought, massive fires, thawing of the polar caps, earthquakes, global changes in agricultural productivity and disease patterns. Thus, the dependency on fossil fuels to meet energy demands should be minimized.
To solve the rigorous threat to earth from global warming, bio-fuels serve as the most feasible source of energy all over the world. The environmental and economical performance of bio-fuel as compared to fossil fuel was analyzed by full Life Cycle Analyses (LCA) in Spain. The Spanish government CIEMAT, carried out two LCA’s so as to compare ethanol-ethanol mixtures with gasoline, and biodiesel-biodiesel mixtures with fuel oil according to ISO 14040-43 standards, these standards evaluate energy and mass balance for two or more objects. It was concluded that carbon dioxide emission during utilization of bio-fuel are lower than fossil fuel and bio-fuel requires less primary energy to be processed than fossil fuels. Bob...

At that time what led to alternative fuels was a better way to make vehicles work better, but what truly led to the development of alternative fuels was to prevent global warming from happening. They are needed to produce less emissions and improve the world`s climate. If in the world the use of

America’s Reliance on Fossil Fuels Essay

1087 words - 4 pages , “We are now running out of oil.” Despite these predictions, the U.S. has produced over 200 billion barrels of oil since the early 1900’s. (The Futurist, 1997) Coal is by far the most abundant of fossil fuels, and will be available for much longer than oil. Having been harvested and burned since the 13th century, a massive infrastructure has been formed to quickly and efficiently mine, deliver, and burn coal. Coal is also the cheapest of fossil

The Depletion of Fossil Fuels

1698 words - 7 pages Abstract— As the world began to raise concerns on climate change and rapid depletion of fossil fuels, there is a need to hasten the solutions for clean energy generation with renewable sources. Solar energy has the potential as an alternative source of energy as it is renewable, universally accessible and emits very low or zero CO2 gases. Solar photovoltaic (PV) system applications are suitable in Singapore due to its equatorial location, with

Fossil Fuels and Alternative Energy

945 words - 4 pages Fossil Fuels Concentrated organic compounds such as coal, petroleum (oil), and natural gas that are found in the Earth’s crust are labeled fossil fuels. Fossil fuels are concentrated biomass generated from the remnants of plants and animals that existed millions of years ago. Moreover, the US Energy Information Administration (EIA) asserts that fossil fuels are utilized for up to 82% of U.S. energy needs (Institute for Energy Research, n.d

Fossil fuels are finite, hard to find and are not cost-effective as biofuels are. Another good thing about biofuels is that don’t contribute to global warming as much as fossil fuels do. Biofuels are mainly used for as a source of energy and sustainable transport. The ways that these biofuels are
