Big Green: Geothermal Heat Pumps

[grahame at bsc-worldwide.com]

Geothermal heat pumps are not and cannot be sustainable or high performance 
systems.
All electric systems need to be eliminated, the excuse that solar PV, etc. can be 
used is invalid.
Heat pumps generate hot water and chilled water to serve standard type air 
conditioning systems, such as fan coil units.
Building energy systems need to be developed that utilize geothermal water for 
cooling and for preheating with solar hot water and/or biogenerators with hot 
water and electric generation.
Zero energy buildings need systems designed for this purpose now, not in 10 
years time.
