Biofuel

is due to photosynthesis (Zhu, et al., 2008). Primary producers use sunlight as energy to convert CO2 and H2O into O2 and Glucose (C6H12O6) (Mohsenpour, et al., 2012). Photosynthesis is not only important for energy and food intake, but also as a biofuel. Microalgae is an important renewable energy source presently, because of its elevated Photosynthetic productivity, and its quick production of biomass (Wahidin, et. al., 2012). The algae is also important in taking in the overproduced CO¬¬2…

They want to increase the use of renewable energy such as geo-thermal power and hydro-electricity. Biofuels is also expected to have a rapid growth in South-East Asia. Even though coal-fired energy is still an important power source in South-East Asia Shell tries to show the economic and environmental advantages of the natural gas as an energy source for…

Challenges of fossil fuels 1. Not renewable energy Fossil fuels comprise of crude oil, coal and natural gas. It is not renewable and cannot be replaced. Plants and animals that existed millions of years ago became buried underneath the Earth’s surface. This formed as the fossil fuels. Since fossil fuels has limited supply, it can’t fulfil the world’s energy demand. Therefore, alternative energy source is needed to replace the fossil fuels. 2. Emission of carbon dioxide Combustion of fossil…

worst economies ever. Due to the the severe dictatorship, the major oil companies in Venezuela are not producing as much oil as they should be decreasing profits by a lot. A solution to this problem is that Venezuela can substitute oil for biomass/biofuel for cars and other users of oil IN the country, but still export oil to other countries and rely on that as their main source of profit. This will increase the amount of profit the country will earn and use the oil they produce for other…

Global Warming Imagine a world in which sea levels rise beyond expectation, threatening the lives of those whom inhabit the surrounding shores (“Conserve Energy Future”). As a result of the consistently rising sea levels, the population will be forced to endure a cataclysmic fate such as the ocean’s conveyor belt becoming altered ultimately resulting in a mini ice age in Europe (“Conserve Energy Future”). However, the fate in which the condition of the world is currently pursuing has the…

which could then effectively result in starvation. The production of biofuels could result in starvation as there will no longer be enough food for people and animals to eat as more of it is being used for biofuels. It could also result in price inflation due to supply and demand because there will be less amounts of crops for people to buy, this makes it harder for already struggling families. The crops needed to make biofuels also take up valuable land and water supply which is crucial for…

converts organic waste such as plant stems, leaves, paper, wood chips, etc into a biofuel. The enzyme that was recently discovered encourages the oxidation of polysaccharides found within the biofuels, and as the polysaccharides are oxidized and broken up, an energy can be harnessed from this and converted to a useable fuel. This is an innovative idea as the enzymes used are not consumed in the process of creating the biofuel. To further that idea, the organic waste would have already been…

In the heterotrophic production, microalgae are grown in the dark and energized by organic carbon substrates in mixing fermenters or bioreactors. With no necessity for light energy, the system can have smaller surface-to-volume ratio of the reactor. The design can be minimal and easier to control its physical conditions due to no exposure to the outside light source. However, this system requires more total operational energy than the photoautotrophic mechanisms, since this process requires the…

came to be. It was made so old products could be made anew (i.e. paper), and it also helped maintain up to 2,400 pounds of carbon dioxide annually. Also more actions have been created to lessen the amount of greenhouse gases that were released into the atmosphere and air. “CFL lightbulbs were created to emit less heat, last 10 times longer than the standard light bulb, and they use two-thirds less energy”. Acid rain is also having things done in order to reduce the amount that falls, and to…

The United States uses over 18 billion barrels of oil every day. This means in turn that a country with just 4.5% of the world's population, is using about 20% of the world's oil. The United States only produces 8 million barrels of oil per day, which is the foundation of the nation's great dependence on foreign oil. One of the largest uses of oil is for gasoline in cars, which can be completely gotten rid of as a whole, There are currently multiple alternatives to fuel cars as opposed to…
