  2. 2. 2 Click to add titleTowards decarbonising heat Maximising the opportunities for Scotland Four key challenges: • Decarbonising heat • Diversifying sources of heat • Reducing pressure on household energy bills • Seizing the economic opportunities
  3. 3. 3 Click to add titleDecarbonising heat Total final energy consumption in Scotland 2011 Source: DECC. (2013). Total final energy consumption statistics (Sub-national): 2011. Heat Electricity Transport Heat accounts for 47% of total CO2 emissions.

  11. 11. 11 Click to add titleSummary and conclusions • Decarbonising heat is essential to meet Scotland’s 2050 CO2target. • A transformation of Scotland’s heat sector is required. • There is considerable uncertainty in terms of costs, performance and deployment of heat technologies. • A “whole systems” approach is essential. • Heat storage provides substantial opportunities to support intermittent and inflexible generation. • Consumer engagement is crucial to deliver:  reductions in heat demand.  selection of heating technology.
