1.0 IntroductionBiodiesel is defined as mono-alky esters of long -chain fatty acid. It is a fuel that derived from the vegetable oils, animal fats, which is similar to the diesel fuel except that it is made from the crops. It is produced from domestically grown, renewable sources, such as crop oils or animal fats which are then chemically converted into biodiesel (Habmigren, 2003). Unlike diesel, biodiesel contains no petroleum products and free of sulfur compounds and aromatics (Habmigren, 2003). Until today, it is still the only alternative fuel for motor vehicle. The biodiesel blends have ranged from 2/98% (B2), 20/80% (B20), to 100% (B100) (Hafman, 2003). The reasons biodiesel is a viable alternative to diesel from fossil fuels for trucks and buses are it can reduce the pollution, it can enhance the country's economy, and it is renewable sources and can produce almost same energy as diesel fuels.…
Biofuels are made from the starch or oil portion of plant materials. Some are even made from the fats of animals. In general, ethanol is the fermented starch fuel and biodiesel is the refined oil and fats. Biofuels are important PART of the solution to declining and ever more expensive petroleum supplies. Biofuels can be used together with technologies such as hybrid vehicles and plug-in vehicles. The Chevy Volt is announced to be a plug-in vehicle with a small Flex Fuel Vehicle engine to charge the batteries. Even the new Cadillac Escalade hybrid has been announced as a Flex Fuel Vehicle.…

Today 's world economy relies more than ever on a constant supply of petroleum to fuel a vast number of different vehicles and other applications. Everything from an internal combustion engine in a car to a furnace in a home use a petroleum product as the form of energy needed to make them function. With the burning of oil for energy comes the unwanted side-product of emissions such as carbon dioxide, which have now been proven to affect the Ozone and weather patterns of Earth. These emissions along with the un-rest in the Middle East, a large supplier of oil to the world, have renewed interest in possible new alternative energy sources to cut down on the global dependence on oil. Researchers at some of the top laboratories and automotive companies are now in the process of experimenting to develop these fuels; they are now closer than ever to having a viable alternative to oil.…
Biodiesel is a renewable fuel produced from vegetable oils. Most biodiesel is made either from crops, recycled cooking oil, or animal fats. Among them, recycled cooking oil is the most effective resource to make biodiesel since it does not compete with food resources. Biodiesel can be used alone or blended with petro-diesel, which can be used in standard diesel engines or heating oil furnaces without modification.…
Thirdly, as a renewable energy, biofuels provide high sustainable energy resources to the society. Since the availability of biomass resources is widely spread, for example, biomass resources can be obtained from food, plant matters, agricultural wastes and living organisms, while these resources are also renewable resources whose rate of production is faster…

As the world demands new measures for our needs, the way that these are found has changed. The term "Biomimicry" has become more familiar in the sector of science and innovation during the last few years, referring to the discipline of looking at nature as an inspirational source to emulate its mechanisms, functions or processes in order to solve human problems. The idea of this approach is to use nature as a mentor, because it has 3.8 Billion years of experience learning and solving problems to live in harmony (Benyus Janine 1998). In this way, Biomimicry can play an important role as a tool for innovation in the search for solutions in nowadays issues such as Energy sources. It is one of the biggest concerns all over the world for the need to generate cleaner, more competitive, sustainable, reliable and secure energy sources (European Commission 2008). This piece of writing will describe how Biomimicry is used as a tool for innovation, how it has been applied to improved current energy technologies, how it can be applied in new renewable energy technologies and It will discuss some advantages and disadvantages of Biomimicry’s approach.…
Algae- most promising alternative renewable energy source available. It decreases the need for fossil fuels and thus makes our environment healthier. Algae oil is produced as much faster as 30 times than other biomass feedstock while its producing amount is up to 300 times more resulting 600 tons of bio-diesel per day which will produce 200MW of electricity per hour.…
Currently the United States imports 317 billion gallons of oil from around the world each year (http://tonto.eia.doe.gov/ask/crudeoil_faqs.asp). This is a major threat to our security because our commerce, defense, and livelihood depend on foreign oil. Because of the current wars in the Middle East, and the sudden increase in oil prices a few years ago, there has been renewed interest in expanding the United States production of biofuel and biodiesel. Biofuel or ethanol is a replacement, or additive, for conventional gasoline; where biodiesel is a replacement to conventional diesel. According to the US Department of Agriculture (USDA), most gas stations in the US now have ethanol as an additive to the gasoline we purchase on a regular basis (www.usda.gov).…
The value in using alternate fuel sources is not going to save any money. The addition cost will eat into our profits and affect future earnings. It is not the right time to try this adventure. We have not developed enough to make this a viable solution. Hopefully, some day in the near future technology will allow us to slow down on our use of gas, and switch to other fuels that will not…

The actual biodiesel yield per hectare of microalgae culture is almost 80% of the yield that of crop oil plants. The microalgae have the potential to produce more than 80% of oil content by weight of dry mass. The selection of potentially high oil producing species will be beneficial as the oil productivity of microalgae culture greatly exceeds the oil productivity of the crop plants.…
The world’s current way to produce, convert and consume energy comes with a price. Development of sustainable energy technologies which can continue providing the society with energy-derived benefits without further environmental destructions is highly desired. A series of green energy solutions, such as solar, wind and biomass energy, are employed in the hope of preventing the impending global energy crisis (Wang, Chem and Huang 2010). Microbial Fuel Cells (MFCs) which capable of harvesting electricity from renewable biomass and organic wastes arise as a promising yet challenging candidate to the existing sustainable energy portfolio (Picioreanu, et al. 2010).…
From geographical perspective, biodiesel feedstock available in Hong Kong is waste cooking oil and animal fats. Due to the limited space, it is not possible to build many biodiesel production plants in Hong Kong, as a result the supply of biofuel would not be enough. Moreover, Hong Kong has heavy use of petroleum, since it is cheaper, more efficient and can be imported easily. The use of biofuel is not desirable, since it is not commonly use. It would be difficult for the government to promote because not many people in Hong Kong drive cars and there are other car fuel options, for example LPG.…
