A frequently emphasised aim of the domestic energy policy is increasing the market share of renewable energy based heating and district heating generation. The National Energy Strategy considers renewable-based heat generation as one of the most efficient method for decreasing the dependence on natural gas and for increasing supply security, with a particular emphasis on using biomass-based and geothermal energy sources. By 2020, the National Renewable Energy Usage Action Plan (NREAP) intends to increase the share of renewable energy sources in the total domestic heat consumption from the present 13.6% to 18.9%, this way contributing to decreasing the dominance of natural gas based heat production.
