I like this...

"In addition it is well documented that the burning of those fossil
fuels is causing a build up of greenhouse gases that is contributing
to global warming. In light of this, it makes sense to make the
best possible use of our natural resources. It is clear that we
need to produce cleaner energy, and microgeneration can help us to
address this issue at grass roots level - in our individual homes.

Run that by me again -- just what fuel does it use to create the
electricity ;-)

Burn a 1 kW appliance on the grid and the efficiency from power station to
appliance is around 40%ish on average. Generate the 1 kW in a boiler using
very clean natural gas at 90% plus efficiency and you see the difference.
Generated at 90% plus efficiency and zero line losses as the burning
appliance is only feet away.

micoCHP still makes sense.

What makes best sense is:

1. Superinsulation,
2. Air-tightness
3. passive solar design.
4. Natural gas boiler using weather compensation control and CH zoning.

Existing homes can do Nos 1 & 2. Not fully in most cases on No. 1.
