Consumption can be displayed as a function of population to
determine the provinces' energy needs based on their population
and industrialisation. When depicted in this way, Spain consumes
5.6 MW h per capita and produces 10.1 MW h per capita on
average. Sparsely populated and industrialised provinces consume
the most (MW h per inhabitant), including Lugo (14.7), Huesca
(10.3), and Tarragona (9.7). On the contrary, the three provinces
with the highest net consumption have average values below the
average: Madrid (4.5), Valencia (4.8), and Barcelona (5.5). It could
be concluded that these highly populated and industrialised have
made efficient use of their energy, or that less populated and
industrialised areas have been less efficient or cost-effective in
terms of their electrical consumption.
