3.2 Cooling thermal and nuclear power plants
Groundwater is not greatly used in energy production (see table 14).
3.3 Heat pumps and geothermal energy
Geothermal energy currently accounts for only a small percentage of the
global electricity production. It is probable that, due to pressure from
anti-nuclear environmental groups and to the continuous increase in oil
prices, this energy source will be more widely used once certain technical
diffi culties are resolved (see chap. A10).
