INTRODUCTION TO ENERGY
Which of the following is an example of chemical energy?
Energy in an apple that a worm eats.
The light bulbs in an office building give off tremendous amounts of heat. Because heat is a
form of energy, this heat could be trapped and used to offset our need for electricity, thus
saving energy and money.
False
Some cars are 100 percent efficient at converting energy from gasoline to energy of motion.
False
Fossil fuels are made by the decay of living things. Because living things are always dying
and decaying, why are fossil fuels not a renewable source of energy?
They take millions of years to form.
Energy from sunlight is _____; if it is harnessed to move a turbine and generate electricity,
then it has been converted to _____.
radiant energy; mechanical energy
ENERGY CONSUMPTION HISTORY
_____ is a type of liquid fuel derived from plant materials.
IS NOT PETROLEUM
As a result of the industrial revolution _____.
profound social and economic changes occurred
The ability to harvest fossil fuels was easier during the Industrial Revolution than before it.
TRUE
Food is shipped thousands of miles throughout our country using various types of
transportation such as trucks, planes, and boats. Food availability would be most affected
by a shortage in which of the following energy sources?
Petroleum
,In the United States, we use energy more efficiently than in the past, and our total energy
consumption is therefore coming down.
FALSE
The use of which energy source gave rise to growth of the US transportation industry in the
1800s, resulting in more people being able to migrate to new areas of the country?
IS NOT NATURAL GAS
Dependence on petroleum in the residential sector may decrease over the next few decades
due to _____.
increase in renewable energy sources
FOSSIL FUELS
The decay and compression of organic material millions of years ago resulted in extremely
fertile soil that helped large rain forests to grow. This describes _____.
fossil fuels
Canada, Russia, and _____ are areas of large oil reserves
Saudi Arabia
Prior to the development of new extraction methods, bitumen, or oil sands, was not
considered part of the world's oil reserves.
TRUE
One reason that people are hesitant to drill for oil in the Arctic National Wildlife Refuge is
_____.
the exact amount and the quality of the crude oil are not known
Because the United States imports about 4 billion barrels of crude every year, at best, the
Arctic National Wildlife Refuge could provide us with nearly one hundred years’ worth of
oil.
FALSE
COAL
Which of the following energy sources is NOT a type of coal or coal-precursor?
Petroleum
Which of the following types of coal requires the most intense pressure in order to form?
Anthracite
The burning of coal is used to heat water in a coal-burning power plant.
, TRUE
Coal is plentiful and inexpensive; therefore, many countries use it despite its environmental
impacts.
TRUE
When coal is mined, it results in significant land destruction. Additionally, the mining of
coal can _____.
IS NOT decrease the greenhouse effect
Coal has no advantage over other energy sources except that it is very cheap.
FALSE
Which of the following describes the clean coal method of coal washing?
Mixing crushed coal with a liquid to remove mineral impurities.
Clean coal, though expensive, creates virtually no environmental impact.
FALSE
SYNTHETIC FUELS
Synthetic fuels are usually _____.
liquid
Synfuels are made from energy sources that are more plentiful than _____.
oil
Using coal, steam, and _____, the Fischer-Tropsch Procedure converts coal into a liquid
fuel.
oxygen
Gas-to-liquid synfuel production can produce diesel, naphtha and paraffin. The formation
of these products usually involves _____.
the Fischer-Tropsch Process
Which of the following is a disadvantage to the coal-to-liquid production of synthetic fuels?
It requires more coal mining.
An advantage of biomass-to-liquid fuel synthesis is that there is no net increase of carbon
into the atmosphere.
True
