Tendencies of World Power Development

Naturevolume 140pages706707 (1937) | Download Citation



IN the modern world the question of natural power supply becomes more and more important. There is the tendency, not by any means confined to power alone, to exploit national resources and to make these available even if they are uneconomic. Power resources are of two kinds: those which are limited, including coal, oil, natural gas, peat, oil-shale ; and those which are perpetually renewed, such as water, wood, wind or even the tides. A recent analysis shows that for 1935 the world power supply consisted of 56·6 per cent coal, 3·7 per cent lignite, 16·5 per cent oil, 3·8 per cent natural gas, 12·8 per cent firewood, 6·6 per cent water.
