Biofuel vs. Conventional Fuel - Biofuel is obtained from lifeless or living microbial resources. Also, various plants and plant-derived materials are used for biofuel manufacturing. In order to be considered a biofuel, the fuel must contain over 80 percent renewable resources. An important process to generate energy, photosynthesis, is the main route through which oxidised carbon (carbon dioxide) is decreased in the daytime and oxidised back to carbon dioxide to generating energy in the night. Biofuel is originally derived from the photosynthesis process and can therefore often be referred to as a part of solar energy source....   [tags: Biofuel]

Biofuel and Aquaculture - Biofuel and aquaculture are two of many industries that extract resources from ecological systems. For either corn-based biodiesel or finfish farming, the production process acquires feedstock from energy-fixing ecological systems such as farm fields and oceans. In cases such as intensified salmon farming, large amount of supplement is applied including fish meal and fish oil obtained from other ecological systems such as wild ocean (Naylor et al, 2000). For residue-derived biofuel and shellfish agriculture, energy input from external ecosystems, although relatively small, is still necessary to meet the energy needs....   [tags: Biodiesel, Natural Resources, Environment] 2091 words

Types of Biofuel - The world at present is facing a crisis of energy shortage. The steady supply of energy from petroleum for the past one and a half century have already passed its peak and is in an exponential decline. The key to resolving the crisis and ensuring a sustainable future is in the development and usage of renewable energy. Biofuel is a renewable source of energy that is derived from organic matter and has a great potential to replace fossil fuel as an alternative source of energy. Human beings have been using biofuels at a very early time in the form of firewood to cook and keep warm, but research and development has to be carried out in order to produce biofuels in forms that are more suitable...   [tags: Earth, Energy Shortage, Petroleum]

Environment or Greed? Biofuel - In reality the fuel used by everyone today is made from corn and could plant corn forever, but eventually it will cause land exhaustion, making it harder to grow any crop at all. Once the land is dried and unable to reproduce anymore food or supply, there will be no more oil production left in the world. This not only increases the process of fuel making, but it also increases the price range, because the modern oil is enriched, and thick, oil like that is hard to reproduce, but it would be easier if the nations switch oil to Low-Carbon fuel, this type of oil helps save more money because it is just taken and recycled like paper plates or plastic water bottles....   [tags: land exhaustion, corn, fuel]

In the United States, in previous years there has been a dependence on these fuels for many purposes. When fossil fuels are burned, a chemical reaction occurs called combustion. This reaction is the cause of a major source of pollution in the environment....   [tags: tending topics in the energy world]

Fossil Fuel versus Biofuels as a Primary Fuel for Transportation - Should we then abandon fossil fuel completely and change to a cleaner type of fuel. Fossil fuel has always been the blame on the bad and polluted environment that we have right now. But we still use fossil fuel, or in this paper we call it petroleum, because it is highly efficient to use it for our transportation fuel. The ‘abundant’ reserve and the increasing development of technology to harness it efficiently from beneath us has made us realize that petroleum is the best fuel for our transportation needs....   [tags: petroleum, biodiesel, oil, fuel]

Creating Biofuels from Waste - Biofuels from Waste Purpose Biofuels mark a great step into today’s efforts to slow down global warming. However, when food sources, such as corn and soy are used as derivatives for ethanol, the impact is far worse than using fossil fuels. Biofuels require more energy to do artificial refinery, cultivating, and collecting; whereas, fossil fuels already meet all the prerequisites through millions of years in the earth, and thus use less energy.

Biofuels - In recent years environmental problems, especially the use of fossil fuels, has become one of the most commonly debated issues. It is widely known that fossil fuels are non-renewable resources and the use of fossil fuels harm the environment, such as the combustion process of fossil fuels that leads to global warming. However, current societies are still dependent on fossil fuels. Because of the environmental problems and in order to decrease the wide-ranging consumption of fossil fuels, researches argue that agricultural based fuel or bio-fuel is one alternative to replace fossil fuels and apply it as a new energy source....   [tags: Environment, Fossil Fuels] 1216 words

Factors of Wind Energy - Wind Introduction Wind is created by temperature gradients , created by differences in heat received on the surface of the earth as a result of incoming radiation from the Sun. These gradients depend on the angle of the incident sunlight, as well as the characteristics of the terrain and are vital for the formation of specific regional climates. Land and water masses have different heat capacities which lead to an uneven heating of the planet’s surface. As there are different temperatures in different regions due to the aforementioned reasons, bulk motion of air molecules is created as the density of air changes with temperature, leading to concentration gradients and pressure gradient...   [tags: renewable, intermittency, biofuels]
