Question 1

In order to get high-quality energy you must use high-quality energy.This rule is the result of which of the following?

Accepted Answer

The second law of thermodynamics states that energy quality degrades over time, meaning high-quality energy is needed to produce high-quality energy due to inefficiencies and entropy.

Question 2

Any energy resource with a low or negative net energy yield cannot compete in the open marketplace with other energy alternatives with high net energy yields unless it is ____.

Accepted Answer

Energy resources with low or negative net energy yields often require subsidies from the government or other funding sources to be competitive in the marketplace, as these subsidies can help offset the higher costs associated with producing or utilizing these energy sources.

Question 3

Which of the following countries is a member of OPEC?

Accepted Answer

Iraq is a member of the Organization of the Petroleum Exporting Countries (OPEC), which is an intergovernmental organization of 13 oil-producing countries.

Question 4

The Arctic Circle holds enough technically recoverable crude oil to meet global oil demand for how long at high production costs?

Accepted Answer

The Arctic Circle is estimated to have enough technically recoverable crude oil to meet global oil demand for approximately 3 years at high production costs.

Question 5

Which country is projected to be the world's largest producer of oil by 2017?

Accepted Answer

The United States was projected to become the world's largest producer of oil by 2017, largely due to the boom in shale oil production.

Question 6

Using a mixture of water,sand,and chemicals under high pressure to free tightly held oil and natural gas is known as ____.

Accepted Answer

Fracking, short for hydraulic fracturing, involves injecting a mixture of water, sand, and chemicals into the ground under high pressure to fracture rock formations and release tightly held oil and natural gas.

Question 7

The Earth Policy Institute estimates that by 2025,China will use how much more oil than the United States?

Accepted Answer

The answer of The Earth Policy Institute estimates that by...

Question 8

What percentage of the U.S.oil consumption was imported in 2012?

Accepted Answer

In 2012, approximately 39% of the oil consumed in the U.S. was imported, reflecting a significant reliance on foreign oil, though less than in previous decades.

Question 9

What do scientists use to show the locations and sizes of various rock formations that may contain oil?

Accepted Answer

The answer of What do scientists use to show the...

Question 10

Nuclear energy is only available to consumers throughout the world at an affordable cost because ____.

Accepted Answer

Governments often provide subsidies for nuclear energy to help cover the high costs associated with building and maintaining nuclear power plants, making it more affordable for consumers. These subsidies can come in various forms, such as direct financial support, tax incentives, or guaranteed loans, which help lower the overall cost of nuclear energy production and thus the price to consumers.

Question 11

Approximately 75% of the world's tar sand resources are located in which country?

Accepted Answer

Canada holds the largest reserves of tar sands, also known as oil sands, accounting for approximately 75% of the global total. These resources are primarily located in the province of Alberta.

Question 12

The point at which pressure in a well begins to drop and production begins to decline is called the ____.

Accepted Answer

The point at which pressure in a well begins to drop and production begins to decline is referred to as the peak production. This term is commonly used in the context of oil and gas wells to describe the maximum rate of production before a decline in output occurs.

Question 13

Which country has the largest portion of the world's light oil reserves?

Accepted Answer

Venezuela has the largest portion of the world's light oil reserves, with its Orinoco Belt being one of the largest deposits of oil in the world.

Question 14

Currently,oil has a high net energy ratio because it ____.

Accepted Answer

Oil has a high net energy ratio because it often comes from deposits that are relatively cheap to extract, meaning the energy and cost required to obtain it are low compared to the energy it provides.

Question 15

Oil sand is made up of all of the following except ____.

Accepted Answer

Oil sand, also known as tar sand, primarily consists of bitumen, water, clay, and sand. Natural gas is not a component of oil sand; it is a separate natural resource often found in different geological formations.

Question 16

What is the total amount of high-quality energy available after the energy needed to make it available is subtracted?

Accepted Answer

Net energy is the amount of high-quality energy available after the energy needed to make it available is subtracted.

Question 17

Which of the following is true if the rate of global consumption continues to grow exponentially at 2% per year?

Accepted Answer

The answer of Which of the following is true if...

Question 18

Almost 72% of the world's reserves of oil shale are found in ____.

Accepted Answer

The United States holds the largest amount of oil shale reserves in the world, accounting for nearly 72% of the global total. This includes significant deposits in the Green River Formation across Colorado, Utah, and Wyoming.

Question 19

If natural gas prices remain affordable,increased production would ____.

Accepted Answer

Affordable natural gas prices can lead to increased production, which in turn makes natural gas a more attractive option for power generation compared to coal, thus potentially reducing the use of coal-burning plants due to economic and environmental efficiency.

Question 20

The second law of thermodynamics dictates that ____.

Accepted Answer

The second law of thermodynamics states that in any energy exchange, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state. This is often interpreted as the quality of energy decreases over time, meaning some high-quality energy is always degraded to a lower quality form (e.g., heat energy).
