Combined heat and power and district heating and cooling (DHC) represent a series
of proven, reliable and cost-effective technologies that are already making an important
contribution to meeting global heat and electricity demand.This report follows the
March 2008 report that hightlighted the energy, economic and environmental benefits
of CHP and DHC (IEA, 2008). That report also provides a technical introduction to
CHP/DHC and describes its global status and potential.
