Fossil electricityshare of electricity generated from coal, oil and gas27%

Heat is all fuel and district heating used in industry, buildings and agriculture, plus the electricity households use for heating, hot water and cooking. Electricity that becomes heat in offices and industry is counted as electricity, so the true heat share is somewhat higher. Fossil heat and the largest source are shares of the fuel and district heating part.
