I have seen some promising info on ground-exchange heat pump
systems that handle domestic hot water as well as space heating/

For the tumble drier I hear there is an advanced solution
known as "clothesline" :-)

I understand that power utilities assisted the original penetration
of CFL's in the US two decades ago because it made economic
sense to them. Interest rates were high, fuel costs rising,
pollution controls needed: building new generating capacity was
expensive. Spend a million dollars subsidizing consumers to
buy CFL's and you can avoid spending 20 million on building a
new power plant. I think Amory Lovins, the Rocky Mountain Institute
guy, was the key proselytizer.
