Mapping and analyses of the current and future (2020 - 2030) heating/cooling fuel deployment (fossil/renewables)

Mapping EU heat supply

Heating and cooling (H/C) account for the major share of final energy demand in industry, services and the residential sector in the EU. It therefore plays a central role in achieving energy policy goals like climate change mitigation, security of supply and competitiveness. At the same time, the official statistics only provide an incomplete picture regarding H/C: Data is often scattered, incomplete or not available.

This project aims to provide a comprehensive picture of the current state of the EU’s H/C sector as well as possible future trajectories until 2020 and 2030.

Main objectives

  • Develop a detailed, consistent and complete energy balance for the H/C sector
  • Provide an overview of the H/C conversion technologies currently in use throughout Europe
  • Assess future trajectories for the diffusion of renewable energy sources in H/C until 2020 and 2030 based on scenario analysis
  • Assess the economic impacts of the faster deployment of renewable energy sources
  • Identify the main barriers to and bottlenecks for the diffusion of renewable energy sources and provide policy recommendations
