This report examines the technologies, current markets and relative costs for heat and cold energy production using biomass, geothermal and solar-assisted systems. It evaluates a range of national case studies and relevant policies. Should the successful and more cost-effective policies be implemented by other countries, then the relatively untapped economic potential of renewable energy heating and cooling systems could be better realized, resulting in potential doubling of the present market within the next few years.
