Article 23 1b.

Member States shall carry out an assessment of their potential of energy from renewable sources and of the use of waste heat and cold in the heating and cooling sector including, where appropriate, an analysis of areas suitable for their deployment at low ecological risk and of the potential for small-scale household projects. That assessment shall consider available and economically feasible technology for industrial and domestic uses in order to set out milestones and measures to increase the use of renewable energy in heating and cooling and, where appropriate, the use of waste heat and cold through district heating and cooling with a view to establishing a long-term national strategy to reduce greenhouse gas emissions and air pollution originating from heating and cooling. That assessment shall be in accordance with the energy efficiency first principle and part of the integrated national energy and climate plans submitted pursuant to Articles 3 and 14 of Regulation (EU) 2018/1999, and shall accompany the comprehensive heating and cooling assessment required by Article 14(1) of Directive 2012/27/EU.
