As depicted from the case study, sugarcane was a major commodity, which facilitated slave trade during the colonial time. Sugarcane was used to manufacture a drink called the Kill-devil, which was better compared to the expensive bear and wine. This drink evolved during the colonial time and kept on changing names from Kill devil to Rumbullion based on the ingredients added to the canned sugar. The name Rumbullion was later shortened to Rum. During this colonial time, sugarcane planting was an important activity since sugar had several important uses. Sugarcane planting was a major factor that facilitated slave trade since the increase in demand of the rum meant that there was the need to plant more sugar. Therefore, this called for more slaves…
In Brazil 10% of the energy used is provided from ethanol. In car fuel the mix of ethanol and petrol is about 85% ethanol with only about 15% petrol but in Australia fuels that contain ethanol are mainly about 10% ethanol and 90% petrol. Though a 85% ethanol blend has started being used in Australia but is not available at all petrol stations. As a car fuel it is blended with petrol to decrease how fast petrol burns, extend petrol reserves and to reduce green house gas emissions. For Brazil the use of ethanol as a car fuel has been very successful as it has a very large starch industry. It is also beneficial to the country economically because the high concentration use of ethanol has replaced expensive oil imports with locally produced fuels.…
Ethanol is definition of stability; a fuel that decreases oil imports, is clean burning, and contributes useful byproducts. Ethanol is definitely part of the solution.KAAPA Ethanol, established in November of 2003, has created many new opportunities and jobs for the industry. Scott McPheeters and Shana Dahlgren gave an enthralling presentation of how ethanol system works and the benefits of the country’s adoption of ethanol and its byproducts. Video presentations were able to captivate the audience’s attention while it presented facts about the…
Also, large areas of agricultural land will be sacrificed to growing ethanol-crops (e.g. sugarcane). This creates problems of soil erosion, deforestation, fertiliser run-off and salinity. Disposal of smelly…
Thesis: “This book asks three principal questions: how did the early English planters in the West Indies respond to the novelty of life in the tropics/ to the novelty of large-scale sugar production? And to the novelty of slave labor?”…
The environmental impacts of farming practices can also be reduced with the adoption of sustainable production methods in the agricultural sector. Growing corn, wheat, rice, and sugarcane produces large amounts of agricultural wastes, some of which are burned, degrading air quality. In the production of cellulosic ethanol, the bulk of the biomass would become a valuable source of energy rather than a waste product. In fact, municipal solid waste (MSW) includes a large volume of cellulosic material that has the potential to be converted to ethanol.…
o Ethanol: biofuel made from plants such as sugarcane, corn and switch-‐ grass. § Convert starch in plant material to simply sugars that are processed into ethanol Advantages of Biofuels (over oil) • Oil is concentrated in small number of countries -‐-‐ biofuels can be grown almost anywhere • If crops not used faster than can be replenished à no net increase in CO2 emissions – [UNLESS existing forests or grasslands are cleared to raise the new crops] • Biofuels are available, easy to store and transport in existing fuel networks (bridge technology)! • Can reduce CO2 emissions by 70% (if forests are not cleared!)…
Instead of growing corn based ethanol, which causes negative effects to our economy and to the environment, researchers have discovered a new product, "cellulosic ethanol." Cellulosic ethanol is formed from waste plant material (cellulose) through a process called “thermo-chemical conversion”. Cellulosic ethanol plants are underway and the future of ethanol energy is making huge advancements. Unlike corn based ethanol, cellulosic ethanol will be less harmful to the environment and more economically…
First of all, the author asserts that the ethanol fuel would not assist to fix global warming problem. Conversely, the lecturer brings up the idea that augmented of ethanol fuel does not adversely affect the environment. In other words, cultivating plants to produce ethanol fuel not only would not ascend the greenhouse gases but also simply compensate disadvantages of burning such gasoline fuel effects on the atmosphere.…
One topic that has been discussed is the idea that the use of ethanol in America is causing deforestation in South American countries such as Brazil. Pressure on the world’s forests from the renewable energy sector also continues to grow. Forests are being replaced with biofuel crops such as sugarcane and other ethanol feedstocks to meet growing global renewable energy demand. Dr. Daniel Nepstad of the Woods Hole Research Center insists that.…
What drove the sugar trade? In the late 1600s and 1700s sugar growing took firm hold in the Caribbean. During that time sugar cane spread even further West. Anthropologists tell us that sugar was first grown in New Guienea some 9000 years ago. Sugar cane grows for 15 months then gets cuts down and gets crushed down.…
In this paper I will explore the use of ethanol as an alternative fuel source. Ethanol is considered a renewable energy resource; as it is derived from crops such as: corn, sugarcane, beets, as well as, other organic materials. The use of ethanol could decrease our dependence on ever depleting supplies of fossil fuels; such as oil.…
The world we live in today is suffering in ways that people before never have. There are constant issues involving environmental hazards, including the alarming rate in which natural resources are being diminished. To help limit the use of one resource, the United States has been turning corn into an ethanol fuel that can be used in vehicles as a gasoline alternative. But this use of corn comes with a set of its own negative effects that extend around the world. The amount of corn based ethanol produced in the United States should be decreased due to its overall negative impact and lack of efficient use.…
Corn crops are responsible for producing numerous valuable resources and products and therefore, corn is a vital part of the nation’s agricultural industry. One of the most valuable products derived from corn is ethanol. Due to the demand for ethanol corn has experienced an increase in value. Farmers are able to charge more for their crop resulting in an increase in price for many other products that rely heavily on these crops. The high demand for products produced from corn have caused many farmers to abandon their original crops and start farming corn in order to tap into the highly profitable corn market. This topic has sparked much debate over the efficiency of this source of energy.…
