China is one of main carbon production countries in the world, with its northeast regions producing the most greenhouse gases. That is because the region’s winter lasts six months long. To survive, people rely on boilers heated by coal. Scholars and researchers have long since looked for an eco-friendly alternative to coal, and now we introduce you to a system that relies on underground sewage to help regulate temperatures. ( NE winter more than 6 months long ) Summer in China’s northeastern city of Harbin — the Provincial Capital of Heilongjiang Province — is enjoyable, but short. Winter begins in October, covering the region in thick layers of snow that last until the next March. HIT Civil & Envtl. Eng. School, Prof. Sun Dexing: ” Most heating in Harbin is provided by boilers, which provide heating for a whole district. For every square meter of area being heated in winter, 40 kilos of coal is consumed over the course of the winter. As the coal burns, the carbon dioxide produced is multiplied by three, which means 120 kilos are discharged for every square meter. There is no way to reduce carbon emissions with these methods.” ( Heating causes emissions ) For every kilo of coal burned, three kilos of carbon dioxide is released into the air. With limited supplies of natural energy source in the world, how will northeast China endure its frigid winter, while still remaining environmentally friendly? HIT Civil & Envtl. Eng. School, Prof. Sun Dexing: ” Solar energy …
