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]

Biofuel and The Racing Industry - The billion dollar racing industry uses high-octane fossil fuels for competition. Lately, ecologists and governments have begun to highlight the need for the racing industry to switch from high-octane fuels to biofuels. The concern for preserving diesel fuels stems from its non-renewal in nature; however, the racing industry should not be forced to use biofuels because of three primary reasons – performance, cost effectiveness and high infrastructure expenditure. The ecologists are of the opinion that the racing industry is an unnecessary burden for the society, that it does not serve any purpose....   [tags: Alternative Energy]

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]

From Oil to Renewable Energy - The world is depended on oil and soon oil will become more valuable than gold and could lead to a worldwide war. Price for oil could soar to above two hundred fifty dollars per barrel. Oil and other fuel cell also cause green house gases which contribute to global warming. China is consuming two times more petroleum than 1996 and India is projected to consume three times the oil it currently does by 2050. Global house gas emission has increased by twenty percent from 2003 to 2006. Energy consumption has increased exponentially throughout the globe....   [tags: Energy]

However, to facilitate communication and terminological discussion, the term is often used in real communicative situations. Term and concepts are equivalent, as per definition, but they are not the same.” Once all term candidates have been retrieved, the terminologist will then continue to work on the system of concepts (Bowker and Hawkins, 2006). In this task, the terminologist analysed the intension of identified concept that the term designate and formulated the delimiting and essential characteristics of that concept, so that he can differentiate it from other concepts....   [tags: aviation, fuel, inclusion] 914 words

Wind Distribution and Capacity Factor As mentioned earlier, wind is stochastic by nature. That means that there is high unpredictability on a small time scale, mainly due to turbulent gusts of wind that greatly change the wind regime locally. In order to find the amount of extractable power annually, a micro-site study should be done, in which the mean wind speeds are recorded, as well as the time availability of these wind speeds (frequency)....   [tags: renewable, intermittency, biofuels]

Promise of Ethanol and Biodiesel - Biofuels, fuels that provide energy using relatively recent organic sources, have been around just as long as cars have. In fact, the first cars ran on peanut oil. Henry Ford, founder of a multimillion dollar American car company, planned to fuel his massively successful Model T’s with ethanol (National Geographic 2013.) However, this revolutionary idea was swept under the rug when the discovery of massive petroleum deposits kept gasoline and diesel cheap and affordable.

The second “giant” that needs to be laid to rest is the fear of agricultural technology and GM crops. Europe has banned the imports of GM crops from the United States and Africa has followed suit. Collier argues these GM crops are good for the food supply as they provide strength, endurance and pest-resistance properties to the seed/food supply. The ban, he exclaims, causes a decrease in grain production by 1-2 percent a year in Europe, causing Europe to lag behind and has cause Europe to lag behind in GM crop technology research as it is only funded through private means and not by the government....   [tags: agriculture, corn, GM]

Alga is a tiny plant that uses photosynthesis to transform carbon dioxide and sunlight into energy at a very rapid rate, and some species can even “double their weight several times a day” (University of Virginia). The rapid growth rate of algae and the fact that half of their composition by weight is lipid oil, the oil used in the production of biodiesel, makes algae a very attractive candidate in the production of...   [tags: Environmental Issues]

According to the National Renewable Energy Laboratory (Arent et al. 2009, 1-2), petroleum accounts for 90% of Hawaii’s energy consumption and 75% of their electricity. Since Hawaii has no pipelines or oil fields, they are forced to import petroleum to accommodate their energy needs (Arent et al. 2009, 1).
