In False Creek, a waterfront community in Vancouver, the energy being used to heat homes comes from an unlikely source. Instead of a boiler, each building's hot water arrives in underground pipes from a city-owned plant—a system called district heating. A growing number of municipalities(市政当局) are incorporating(并入) this strategy(策略) into their plans to cut fossil fuel consumption(化石燃料消耗), using renewable energy sources such as geothermal(地热的) or solar energy instead of oil or natural gas. But in the case of False Creek, they're using sewage.
It turns out that the water flowing out of your kitchen sink, washing machine, shower, dishwasher and yes, toilet is warmer than when it first shows up at your house. Wastewater flowing through municipal sewer pipes can maintain a temperature of between 10℃ and 20℃ even in the coldest months. So rather than waste that heat, False Creek uses it. In 2022, the local utility(公用事业) said it generated(产生) 23,441 megawatt hours of thermal energy from sewage water—enough to heat 3,000 residential apartments for a year. "What we're doing is turning wastewater into a resource," says Derek Pope, manager of neighbourhood energy for Vancouver. "In doing so, we're able to heat up an entire neighbourhood."
