Non-fossil fuel used in China for winter heating

Transcript

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.
