Document ATM-NUCL-GNL-CHE UN 135315 - Energy - Sources of power

Dimensions: 19,4 X 12,6

Oil was the cheapest form of energy until relatively recently. The industrial world thrived on it. Many countries became dependent for their food on its by - products - fertilizers and pesticides. Other sources of power - the sun, the wind, the tides, steam in the earth's crust, coal, nuclear fission and fusion - were neglected as too expensive. Some are more costly to the environment to exploit than others. But many are relatively inexhaustible by comparison with oil. A fair price for energy must be fair to buyers and sellers, but also to the earth and to future generations.

A view of Intersecting Storage Rings (ISR), collision rigs, and septum magnets at the European Organization for Nuclear Research (CERN) in Switzerland. Two continuous streams of accelerated protons travel in opposite directions at the same speed in lanes which cross and recross at regular intervals. Collisions occur at the points of intersection. The septum magnets steer the incoming protons towards their final orbit.
