Alternative Energy: Net Energy Analysis, Conservation, Pollution and Water

Summary: This article was about hydraulic fracturing also called fracking which is used in drilling for natural gas. The passage discusses the benefits and drawbacks of using fracking, and brings up the question of whether we should be using this method to collect natural gas.

Terms:
Fracking- hydraulic fracturing in rock that allows natural gas to be harvested with the use of water.

Discussion:
1. What are the main concerns of the anti-drilling groups?
The main concerns are the harmful chemicals that are used in fracking and also the destructive effects that drilling into the earth has on the environment as well.

2. What are the main concerns of the pro-drilling groups?

the major concerns of the pro-drilling groups are finding ways to harvest the natural materials from the earth more efficiently in order to gain the most profit, and following state regulations.

Questions:

What are some of the benefits of banning hydraulic fracturing?
Why are some of the chemicals used in fracking?
Is hydraulic fracturing really necessary? Are their any alternatives?

Relocalization in Cuba and Ireland

Summary: The Kinsdale article was a very in depth evaluation of Ireland's current energy plan for a more efficient future. Whats beneficial about this energy action plan is it will not only boost Ireland's economy and help the environment, but it will benefit the world as a whole if we follow this country's example. I was impressed to see how well thought out the energy plan was, right down to how it will affect the housing and Health care.
The article about Cuba was about how the country is surviving with low oil supplies and how they have turned to using every resource to its full potential; making sure not to waste anything that could be recycled and reused. The entire culture has been transformed to not be so dependent on oil and has reaped the economical benefits.

Terms:
Peak Oil- The point in time when the maximum rate of oil production occurs. This will be the point in our history where we start running out of oil and be forced to find a new energy source.
Decentralized agrarian society- a closely governed agricultural based society with a limited dependence on oil.

Discussion:
How Did the Cubans effectively handle the collapse of the Soviet Union and the loss of fossil fuel imports?
They found a new way to survive without a dependency on oil by being more efficient and cutting down on how much fossil fuel emissions they produce that pollute the atmosphere.

After reading the TC Local Plan or the Kinsdale Relocalization Plan do you think relocalization is an effective response to reduce energy availability? What are the merits? What are the drawbacks?
After reading the Kinsdale Relocalization Plan, i believe that relocalization is an effective response to reduce energy availability, but it is really only the beginning of what we should be doing to protect our environment. The benefits are that this will reduce our dependency on fossil fuels and benefit our global economy as a whole. The drawbacks are it is a temporary fix, and it is just a plan and has not been put into action yet.

Questions:
1. How are the changes in housing beneficial for Cuba's economy? for Ireland's?
2. How will the introduction of alternative fossil fuels improve Ireland and Cuba's economy even more?
3. What are some of the major benefits of relocalization?

Eating Fossil Fuels: The Food System

Summary: Oil, Food and the Coming Crisis in Agriculture
This reading was about our dependency and consumption of oil and other natural energy resources as a human race. It discusses how oil is an issue for countries all over the world, and is often so expensive that it causes massive damage to an economy. This passage also perdicts the collapse of our current system of agriculture as it is entirely dependent on industrial goods that consume fossil fuels. North Korea is the main example used, as their agricultural economy has collapsed because of their thirst for oil and heavy consumption of natural resources. Their example is a model that heads as a warning to other countries to not take advantage of what they have, as it might backfire on them in the end.

Terms:
Hydrocarbons: an organic compound consisting entirely of hydrogen and carbon.
Liquid Natural Gas: natural gas, mostly methane that is liquifyed so it can be easily stored and transported.

Discussion:
How have fossil fuels added to the dangerously vulnerable situation of modern agriculture?
They have aided the destruction of our enviornment, and industralization has fueled the need to harvest more and more fossil fuels even though our natural supply is running low. The more fossil fuels we produce, the more we damage our land and ruin the ability of plants and crops to grow.
What lessons, if any, can the US learn from North Korea's agricultural collapse? Not to exploit our natural resources to the point of destruction of our land, which will cause our economy to collapse.
Questions: When did humanity really start exploiting oil resources?
When industralization took off in the early 1800's.

Who accurately predicted when the United States' dependence on oil would peak? When was this?
A petroleum geologist named Dr. M. King Hubbert. He perdicted that american oil dependence would peak in 1970.
What is an example of a widely used product that comes from natural gas?
Artificial fertilizers used in agriculture are produced by the hydrocarbons that come from natural gas.

Joyride: Energy Culture, streetcars cars and suburbs.

Summary: The reading for this week was about how we as Americans take our fossil fuels and other natural resources for granted because we have become so accustomed to luxury items such as automobiles, trolleys and train cars. So accustomed in fact, that they have become apart of our culture and often vital components of daily life. The passage starts off with an example of the American dream and how we view modern machines as items that give us a ticket to freedom from our everyday lives. It then goes on to discuss how machines used in transportation have evolved throughout history(from the early 1900's til today) and how this impacted our culture, economy and standard of living. During wartime, automobiles and other modes of transportation were very important. Even the materials they were made out of were just as important in a time where the economy was suffering.

Terms:
Electric streetcar- an early form of modern transportation, also known as a cable car, developed in the late 19th century in San Fransisco, California as efficient public transportation.
Technocentric Economy - our society's dependence and reliance on technology.
Federal Housing Administration (FHA)- the largest insurer of mortgages in America developed in the 1930's.

Discussion:
How did the car/tractor shape American culture and American's lifestyle?
The automobile changed American culture by starting off as a private luxury and transforming into a public necessity. It has become permanently meshed into our culture; through train cars transporting our food and other goods from place to place, to machines and cars harvesting food and making sure people get to where they need to go.
How did energy contribute to the post-WWII housing boom and suburban development?
Energy has contributed to the industrialization of the United States by producing its own energy and materials such as petroleum and other metals on American soil, allowing us as a nation to accumulate a vast income and jump-start our economy to make room for other luxuries such as suburban development.
Questions:
Who invented the electric streetcar?
Frank Julian Sprague; a former follower of Thomas Edison.
How did automobiles and other machines like it affect agriculture?
It allowed farmers to harvest crops more efficiently and at a faster rate, but machines were costly to maintain and often caused farmers to be trapped in debt.

What era did suburban expansion really take off in the United States?
The 1950's and 1960's.

New Advancements in Technology

Summary of Chapter 6: Transportation and Information

This chapter was about the new advancements in technology that came from the production of fossil fuels in today's modern age. There is a list of these new innovations in chapter six, which include steam engines in trains, fission reactors, aluminum, airplanes, pipes as well as computers, the television and cars. The purpose of this chapter is to conclude the text and show all of the uses of products powered by fossil fuels.

Discussion:
How might better transportation make an economy more efficient?

Better transportation would make an economy more efficent because if we could create our own energy without doing significant damage to the environment, and ultimately give the ecomony the stimulation it needs to get out of the recession. Better transportation over the years has also benefited the economy by allowing us to gain access to certain natural resources and knowledge not previously attainable.

How can better communications be used to reduce energy use?

Talking on the cell phone instead of driving somewhere to talk with someone is a great example of more efficent energy use, because it uses less fossil fuels and energy. This reduction of energy useage can be practiced by everyone, is as simple as cutting back on how much power we use everyday.

Other Thoughts:

What is the most prominent invention mentioned in chapter six still in use today?

In my opinion, the invention used the most in today's society is aluminum. This is because it is used in a variety of machines and inventions that have revolutionized the way we live today.

What new idea was invented by James Watt? How did this machine revolutionize methods of transportation? The steam engine; this machine inspired modern innovations such as internal combustion engine as well as other mechanisms in use on automobiles.

Where are oil tankers shipping the most oil?

Between the Persian Gulf and Japan.
