Table notes
a. ^ Note on 'installed capacity' and 'potential energy'. The former is an estimate of the maximum productive output of a given technology or individual generation station at a single point in time. The latter takes into account the likely intermittency of energy supply and is a measure of output over a period of time. Thus, for example, individual wind turbines may have a 'capacity factor' of between 15% and 45% depending on their location, with a higher capacity factor giving a greater potential energy output for a given installed capacity. The 'potential energy' column is thus an estimate based on a variety of assumptions including the installed capacity. Although 'potential energy' is in some ways a more useful method of comparing the current output and future potential of different technologies, using it would require cumbersome explanations of all the assumptions involved in each example, so installed capacity figures are generally used.

Famous quotes containing the words summary, scotland, resource and/or potential:
“Product of a myriad various minds and contending tongues, compact of obscure and minute association, a language has its own abundant and often recondite laws, in the habitual and summary recognition of which scholarship consists.”
—Walter Pater (1839–1894)
“The “second sight” possessed by the Highlanders in Scotland is actually a foreknowledge of future events. I believe they possess this gift because they don’t wear trousers.”
—G.C. (Georg Christoph)
“If there is nothing new on the earth, still the traveler always has a resource in the skies. They are constantly turning a new page to view. The wind sets the types on this blue ground, and the inquiring may always read a new truth there.”
—Henry David Thoreau (1817–1862)
“Views of women, on one side, as inwardly directed toward home and family and notions of men, on the other, as outwardly striving toward fame and fortune have resounded throughout literature and in the texts of history, biology, and psychology until they seem uncontestable. Such dichotomous views defy the complexities of individuals and stifle the potential for people to reveal different dimensions of themselves in various settings.”
—Sara Lawrence Lightfoot (20th century)
