Combined Heat and Power (CHP)
In the United States, most electricity is generated by thermal power
plants, which have an average efficiency of 30-33 percent because
two-thirds of the energy used is released in the form of waste heat.
Combined heat and power (CHP) captures this heat and typically
distributes it to nearby buildings through a network of pipes known as
a district heating system to provide both space and water heating. CHP
Stupid solution. How much heat is lost in the pipes?


Its waste heat. If it wasn't got rid of via the district heating
system it would have to be got rid off some other way.
Eg by means of cooling towers which would themselves cost money to
build and maintain.


You obviously don't understand that piping natural gas into the home is
100% efficient and requires no insulation.

Well another possiblity is to let each home generate its own electric
power.

The waste heat is then directly available to the home.

Eg. from fuel cells.
