In Spite of all the efforts that are already planned in the
developed countries to 
promote energy efficiency, the world energy consumption will
grow very 
importantly in the 21st century due to the combination of
world population and 
PIB increase. 

The ultimate production potential from renewable energy
sources is extremely 
high. Unfortunately, the rate at which this potential could
substitute the use of 
fossil based energy production remains very low.
This predominance of fossil fuel electricity production now
provokes a serious 
threat on climate change. It is therefore indispensable to
speed up the 
development of renewable.
Among all these new sources, geothermal energy has several
interesting 
characteristics: it can give base load production and it is
less sensible than 
hydro power to climate evolution.
Among all, the geothermal power production schemes, heat and
power 
production from EGS are the only way to access geothermal
resources in an 
appreciable percentage of the continents. Consequently, the
European efforts 
to fill the research gaps that are still preventing today
the full deployment of 
EGS exploitation are extremely important for our common future.
