Statements
a. Classify the energy sources based on their availability in nature and further expand
on the classification of one type of these sources detailing their capability to renew
themselves at a sufficient rate in human time frames. Which type of energy source
is geothermal energy?
b. Primary energy sources are:
i. Renewable at human time frames
ii. Nonrenewable at human time frames
iii. Renewable or nonrenewable, it depends on the energy sources
iv. None of the above
c. Recall the principal unit measures of energy forms.
d. The basic energy unit of the metric system (SI) is:
i. Joule, J
ii. Watt, W
iii. Calorie, Cal
iv. Watt-hour, Wh
e. The Watt is defined as:
i. J s
ii. J
iii. J=s
iv. s=J
f. What is intended with the definition of primary energy, final energy and net
energy?
g. What is the difference between final energy consumption and demand?
h. Can you state what are the three main end users that have more pronouncedly
contributed in recent years in the final energy consumption of developed
countries?
i. What have been two noteworthy consequences of the historical use of nonrenew-
able energy sources, often unregulated, poorly regulated, inefficient, or over-
exploited, in contrast to renewable energy sources? Summarise remarkable
problems associated with these consequences.
j. Define low-carbon buildings and expand on their importance for sustaining
human activity with a limited impact on the environment.

tive energy building?
i. Switzerland
ii. France and United Kingdom
iii. Italy and France
