kun ainoa ratkaisu on ydinvoima, näyttävät kaikki muut vaihtoehdot tutkimattomilta.. Ei ole mitään syytä tutkia kallista fuusiovoimaa, kun tutustuu seuraavaan artikkeliin:
Geothermal energy
in Lund – past and
future
Sweden – The first geothermal heat pump
plant was put in operation in 1984. It has
been successful from the technical,
economic and environmental points of view.
It is therefore not surprising that Lunds
Energi AB (LE) is again choosing the
geothermal energy option to expand its heat
production. The groundwater of the existing
system has an initial temperature of about
22 ºC and is re-injected back at around 2 – 4
ºC. The new system will utilise deep
geothermal wells, using geothermal water of
> 100 ºC, from about 3500 m deep.
The energy system analyses show that as
much as 250 GWh/year can be extracted
from the high temperature fraction (using
geothermal water of > 100 ºC) and 140
GWh/year from the low temperature
fraction (with initial temperature of about
22 ºC). The district heating system in Lund
will then get about 65% of its total energy
from geothermal energy. The new
geothermal energy system will reduce the
use of geothermal energy from the older
heat pump system.
