Electrical heating

kg CO2 per MWh produced heat (Source:Sven Werner/B Karlsson)

Local emissions (allpower is CO2 free)

Global emissions (allpower valued as coalcondensing power)

Net emissions of carbon dioxide for different fuels and technical solutions when coal condensing power is marginal production in the European power system

System perspective

• 1 kWhel always means 1 kg CO2 everywhere

• Electricity price x specific consumption = constant

Potential

• Emissions today in Sweden 60 Mtonne

• Potential CHP -30 Mtonne

• Improved efficiency -30 Mtonne

• Means no climate change contribution
