The Toppo T'ali at Trollhdttan about 1800.
The accompanying map should furnish a clear idea of the distribution of
water-power in Sweden, and also of that portion of it which has been actually
utilized. The total supply of economically available water-power has for this
purpose been assumed to be 6 20(1000 horse-power.
It may also be of interest in this connection to give the latest available official
data as to power consumption for industrial purposes. In the statistics of the
Board of Trade for 1910 and 1912 we find the following figures:

Total 66426 67 935 479237 629772 545 663 697 707
These figures show that respectively 60^ and of the total power consumed
was by water-power. They show also that, while during the year 1910
about 46 % of the total water-power used, was still consumed by direct shafting
without electric transmission of power, this same figure for 1912 has declined
to 36%. There- is no doubt that the near future will see a still more remarkable
change in this respect, as by far the greater part of the water-power
recently equipped or now in process of equipment —- the latter amounting to
about 100 000 turbine horse-power ^ will apparently be transformed into electric
energy for transmission over shorter or longer distances.
One may classify the water-power plants equipped at the end of 1913 as
follows:
