Question 1

________ can easily be moved across land in pipelines,but must be transported in special refrigerated ships to move across oceans.

Accepted Answer

Natural gas is often transported across land via pipelines due to its gaseous state, but for oceanic transport, it needs to be liquefied and kept at very low temperatures in specialized LNG (Liquefied Natural Gas) carriers.

Question 2

Solar photovoltaic energy is highly versatile and can be used in a variety of dispersed settings.Which of the following would not be a good location to harness large amounts of this form of energy?

Accepted Answer

D

Question 3

Fossil fuels currently supply about ________ percent of all world commercial energy supplies.

Accepted Answer

Fossil fuels, including coal, natural gas, and oil, are the dominant source of energy worldwide, providing approximately 87% of all world commercial energy supplies. This high percentage reflects the global reliance on these resources for electricity, heating, transportation, and industrial processes.

Question 4

________ is an alternative fuel that can be made from any fat or vegetable oil.It can be used in any diesel engine with few or no modifications.Although it does not contain petroleum,it can be blended with diesel at any level or used in its pure form.

Accepted Answer

Biodiesel is the correct answer because it is a type of alternative fuel that can be produced from natural oils, such as vegetable oil or animal fat, and used in diesel engines with minimal modifications.

Question 5

Most of our energy waste in North America results from

Accepted Answer

Technological inefficiency is the primary cause of energy waste in North America, as many systems and devices do not use energy in the most effective way possible, leading to unnecessary loss.

Question 6

The United States,making up less than 5 percent of the world's population,uses more than ________ of the world's commercial energy production.

Accepted Answer

The United States, despite having less than 5% of the global population, consumes about a quarter (1/4) of the world's commercial energy production, highlighting its significant energy consumption relative to its population size.

Question 7

A glass greenhouse on the south side of a building is an example of

Accepted Answer

A glass greenhouse on the south side of a building utilizes passive heat absorption by capturing and storing solar energy without the use of mechanical systems, which is characteristic of passive solar design.

Question 8

Worldwide,coal deposits are

Accepted Answer

Coal deposits are widespread and extensive around the world, found on every continent and in over 70 countries, making them a significant source of energy and industrial raw materials.

Question 9

In terms of generating electricity,fuel cells are ________ than thermal-conversion machines because the chemical energy of a fuel is ________.

Accepted Answer

Fuel cells are more efficient than thermal-conversion machines because they convert the chemical energy of a fuel directly into electricity without an intermediate combustion cycle, avoiding the energy losses associated with combustion processes.

Question 10

Which of the following statements is false?

Accepted Answer

The statement that improving standards of living require increased energy consumption is false because advancements in technology and energy efficiency can lead to improved living standards without necessarily increasing energy consumption.

Question 11

Most of the world's nuclear reactors are of the ________ type.

Accepted Answer

Most of the world's nuclear reactors are of the pressurized water (PWR) type, which is the most common design used in commercial power generation.

Question 12

Which of the following statements is true?

Accepted Answer

The United States has limited proven oil reserves, and at current consumption rates, these reserves would last only a few years.

Question 13

Nuclear power provides about ________ percent of the US energy supply.

Accepted Answer

Nuclear power accounts for about 9% of the total energy supply in the United States, reflecting its role in electricity generation rather than the total energy mix, which includes transportation, heating, and other uses.

Question 14

A reason to encourage green building designs would be that

Accepted Answer

Green building designs focus on energy efficiency, which can significantly reduce the amount of money spent on heating, cooling, and electricity. This is because these designs often incorporate renewable energy sources, improved insulation, and other technologies that lower energy consumption.

Question 15

________ is derived from ancient swamps and bogs,where standing water prevented decay and allowed plant matter to accumulate and ________ is derived from plankton and algae,mixed with mud and sand on ancient sea beds.

Accepted Answer

Coal is formed from plant matter in ancient swamps and bogs where waterlogged conditions prevented decay, allowing the plant matter to accumulate. Oil, on the other hand, is formed from the remains of marine organisms such as plankton and algae, which were mixed with mud and sand on ancient seabeds.

Question 16

For much of the past decade,battles have been going on over oil and gas drilling in

Accepted Answer

The Arctic National Wildlife Refuge has been a focal point of debate over oil and gas drilling for many years, with environmentalists and energy companies often at odds over the issue. The other locations listed have not been central to such high-profile battles over drilling.

Question 17

Sweden,Denmark,and Switzerland have higher standards of living by most measures than Americans or Canadians

Accepted Answer

Sweden, Denmark, and Switzerland have higher standards of living by most measures compared to Americans or Canadians, even though their energy use is significantly lower. This demonstrates that a high standard of living can be achieved with efficient energy use and sustainable practices.

Question 18

Control rods in a nuclear reactor are used to

Accepted Answer

Control rods in a nuclear reactor are used to absorb neutrons, which helps to control the rate of the nuclear reaction and maintain it at a safe level.

Question 19

The most likely disaster in a nuclear power plant is that

Accepted Answer

Nuclear power plants rely on cooling systems to remove heat from the reactor core. If these systems fail, the core can overheat, potentially leading to a meltdown. This is a more likely scenario than the other options, as nuclear power plants are designed with numerous safety systems to prevent explosions or uncontrolled reactions.

Question 20

Most useful oil deposits are usually found

Accepted Answer

Most useful oil deposits are found saturating porous rocks, similar to how water saturates a sponge. This allows for the extraction of oil through drilling, where it is then pumped out from these porous reservoirs.
