In recent years, aft P14 The average DH growth in northern China is slowing down, while the development in central and southern China is increasing. We expect the annual growth of building floor area covered by DH to be between 4-6 % for the coming ten years. The annual DC growth is expected to be above 15 % for the co P15 1200 MW CHP coal plant with cooling fans to the left on picture currently supplying heat for the new town area in Tongchuan, but it has the capacity to supply much more. DISTRICT HEATING IN CHINA FOCUS BIG MARKETS: CHINA & POLAND By Senior Advisor John Tang, Danish Energy Agency (Beijing) P16 Natural gas, electricity, geothermal heat, biomass, solar energy, industrial waste heat, ultra-low emission coal (CHP) and nuclear energy are in China defined as sources for clean heating. The share of clean heating was 34 % in North China in 2016 according to the government and it is expected P17 Outside the DH sector the heat demand and supply cannot be found in any statistics. This means that predictions for the future size of the DH sector are tenuous and mostly based on present district heated floor area. In Figure 1, eight different prediction models are shown for the future size o P18 A Chinese coal stove in a private apartment and exhaust from the same stove nearby power plant is not used to supply heat.

The weather moves from cold and rainy to slightly warmer and rainy, with occasional detours through disturbing heat waves along the way. In the same way, EU politics are defined by phases.

In the face of scepticism about her environmental credentials, notably from Greens and Socialists, she committed to bringing forward a plan for a P30 With this in mind, the emerging EU discussion on sector coupling (e.g. power-to-heat) is of the highest strategic importance for our industry.
