00:00As Northern China slips into a winter chill, renewables and waste are becoming new sources
00:11of energy to heat homes.
00:14In Lanzhou City, the capital of Northwest China's Gansu Province, sewage is being used
00:19for heating for the first time.
00:21Heat pumps extract heat from the treated wastewater as it leaves the sewage treatment plant.
00:27Compared to fossil fuels, heat pump wastewater systems can reduce carbon emissions by 47,000
00:33tons annually.
00:35In another district of the city, geothermal water, which is pumped from 2,300 meters below
00:41ground, is the main heat source.
00:43The temperature of the water can reach 74 degrees Celsius.
00:47Thermal water heating can reduce coal use by 7,000 tons annually and thus reduce carbon
00:52emissions by 19,000 tons.
00:56This year, the temperature is higher than last year.
00:59Data shows that as of last year, there were 41 million people using renewable energy for
01:04heating in the country's northern region.
