极端高温事件的频率和强度都在增加,由于不断增长的冷却需求,对电力基础设施构成挑战,并对城市居民构成公共健康风险。为了最大限度地减少极端高温增加的风险,关键是(a)预测随着城市变暖而增加的电力使用,以及(B)确定最脆弱的社区,部分原因是缺乏空调(AC)和无力负担增加的能源。在这里,我们利用智能电表数据,从180 476个家庭在南加州量化增加居民用电每度变暖的每个人口普查区。我们还计算了AC渗透率,发现空调在较贫困的人口普查区不太普遍。利用世纪末的气候变化预测,我们发现,55%和30%的人口普查区被确定为最脆弱的预计将经历超过16和32极端炎热的日子,每年分别。
Extreme heat events are increasing in frequency and intensity, challenging electricity infrastructure due to growing cooling demand and posing public health risks to urbanites. In order to minimize risks from increasing extreme heat, it is critical to (a) project increases in electricity use with urban warming, and (b) identify neighborhoods that are most vulnerable due in part to a lack of air conditioning (AC) and inability to afford increased energy. Here, we utilize smart meter data from 180 476 households in Southern California to quantify increases in residential electricity use per degree warming for each census tract. We also compute AC penetration rates, finding that air conditioners are less prevalent in poorer census tracts. Utilizing climate change projections for end of century, we show that 55% and 30% of the census tracts identified as most vulnerable are expected to experience more than 16 and 32 extreme heat days per year, respectively.
