According to the IEA, energy security and renewable technology could make a direct contribution to heating in the form of increasingly affordable solar and geothermal sources.
Heat from solar, geothermal sources, and heat pumps, is increasingly economic but is often overlooked in government programmes that promote public acceptance and provide incentives for renewable electricity and energy efficiency. The IEA suggests that the direct contribution that renewable energy can make to domestic or commercial space heating and industrial process heat should be examined more closely.
