Alongside policy support, drivers supporting the roll out of district heating
include the decarboni - sation trend, as district heating can harness a range of renewable or low - carbon energy sources such as
biomass and geothermal; energy security, as district heat - ing can improve the reliability of access to energy at both the user and national levels by re - ducing reliance on cen - tral energy networks; and energy efficiency, which is higher with district heating than
traditional boilers.
