Making Ethanol from Sugarcane


This segment highlights how sugarcane is processed into ethanol for fuel and other uses.

Sugarcane ethanol has proven to be one of the most environmentally safe alternative fuel sources. In addition to its green energy properties, sugarcane ethanol has fueled the Brazilian economy for over a decade. The Brazilian automotive industry have developed a complex, “Flex Fuel” engine that allows vehicles to run off of both gasoline and ethanol. Also, sugarcane ethanol has been one of their leading exports in the global economy. Due to recently discovered fuel deposits in Brazil and around the globe, there has been a decline in the need for sugarcane ethanol. This has negatively impacted the economy in addition to the Brazilian job market. But thanks to the engineering of cellulosic ethanol, Brazil is striving to become the green energy superpower yet again.

 

Questions to Ponder: Since cellulosic ethanol production is so expensive, do you think that will deter production and customers from purchasing it? Do you think that Brazil will ever become independent of fossil fuels as a result of their successful sugarcane ethanol production?

Ethiopia’s Dam Problems

“Ethiopia is three years from completing a dam to control its headwaters, and while Egypt points to colonial-era treaties to claim the water and to stop the project, the question remains as to who own the Blue Nile.”

This 7-minute Geography News Network podcast (written by Julie and Seth Dixon) touches on some key geographic concepts.  85% of the Nile’s water comes from the Blue Nile that originates in the Ethiopian highlands–it is the Blue Nile that Ethiopia has been working on damming since 2011.  The Grand Ethiopia Renaissance Dam (GERD) will be located  near the border with Sudan.  Egypt is adamantly opposed to Ethiopia’s plan and is actively lobbying the international community to stop construction on the dam, fearing their water supply with be threatened.

Welcome to Baku, the Fiercely Modern, Millennia-Old, Capitalist-Socialist, Filthy-Rich Capital of Azerbaijan

“Since 2006, when the opening of the Baku-Tbilisi-Ceyhan pipeline prompted a surge in crude oil exports — up to a million barrels a day travel through neighboring Georgia and on to Turkey and the West — there’s been no shortage of cash in Baku. Now, the city is eager for the prestige that goes with it.”

Baku is described in this article as an East-West, socialist-capitalist, Muslim-secular, ancient-modern mishmash due to the numerous cultural and political interactions that it has had.  This makes for a fascinating cultural landscape emerging in a city that has been dubbed “the Dubai of the Caucasus” but still has a rich Silk Road history.  Caspian Sea oil lies at the heart of Azerbaijan’s geopolitical importance and cultural aspirations.

Mapping the Anthropocene

Via Scoop.itGeography Education

As follow-up to an earlier post about how we have enter the age of the Anthropocene, this stunning map is a fantastic visual representation of the forces that merit the dawning of a new geologic age.  This map depicts the lights at night, major roads, railways power lines, oversea cables, airline routes and shipping lanes.  It also expands the areas according to population size.  For more on the production of this map, see the Globaia website.
