You overlooked one thing, which is that it is a lot more expensive to heat with electricity than combustion. Compare: - Burn stuff, make steam, turn generators, step up voltage, transmit power many miles over big wires, step down voltage, transmit to house, and run thru electrical element to generate heat - pipe stuff to house, burn it, pump hot water around your house. .hc > > _ _ __ ___ _____ ________ _____________ _____________________ ... > | Mathieu Bouchard - tél:+1.514.383.3801, Montréal QC > Canada_______________________________________________ > [email protected] mailing list > UNSUBSCRIBE and account-management -> http://lists.puredata.info/ > listinfo/pd-list ------------------------------------------------------------------------ ---- Computer science is no more related to the computer than astronomy is related to the telescope. -Edsger Dykstra _______________________________________________ [email protected] mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
